S5 Ep 208An incident response reveals itself as GhostShell tool, ShellClient.
Guest Mor Levi, Vice President of Cyber Practices from Cybereason, joins Dave Bittner to discuss her team's work on "Operation GhostShell - Novel RAT Targets Global Aerospace and Telecoms Firms." In July 2021, the Cybereason Nocturnus and Incident Response Teams responded to Operation GhostShell, a highly-targeted cyber espionage campaign targeting the Aerospace and Telecommunications industries mainly in the Middle East, with additional victims in the U.S., Russia and Europe. The Operation GhostShell campaign aims to steal sensitive information about critical assets, organizations’ infrastructure and technology. During the investigation, the Nocturnus Team uncovered a previously undocumented and stealthy RAT (Remote Access Trojan) dubbed ShellClient which was employed as the primary espionage tool.

S5 Ep 207Malware sometimes changes its behavior.
Dr. Tudor Dumitras from University of Maryland joins Dave Bittner to share a research study conducted in collaboration with industry partners from Facebook, NortonLifeLock Research Group and EURECOM. The project is called: "When Malware Changed Its Mind: An Empirical Study of Variable Program Behaviors in the Real World." In the study, the team analyzed how malware samples change their behavior when executed on different hosts or at different times. Such “split personalities” may confound the current techniques for malware analysis and detection. Malware execution traces are typically collected by executing the samples in a controlled environment (a “sandbox”), and the techniques created and tested using such traces do not account for the broad range of behaviors observed in the wild. In the paper, the team shows how behavior variability can make those techniques appear more effective than they really are, and they make some recommendations for dealing with the variability.

S5 Ep 206When big ransomware goes away, where should affiliates go?
Our guest Doel Santos, Threat Research Analyst at Palo Alto Networks, joins Dave Bittner to talk about Unit 42's work on "Ransomware Groups to Watch: Emerging Threats." As part of Unit 42’s commitment to stop ransomware attacks, they monitor the activity of existing groups, search for dark web leak sites and fresh onion sites, identify up-and-coming players and study tactics, techniques and procedures. During their operations, Unit 42 observed four emerging ransomware groups that are currently affecting organizations and show signs of having the potential to become more prevalent in the future. Doel discusses these (AvosLocker, Hive Ransomware, HelloKitty, and LockBit 2.0) with Dave.

S5 Ep 205Groove Gang making a name for themselves.
Guest Michael DeBolt, Chief Intelligence Officer from Intel471, joins Dave Bittner to discuss their work on "How Groove Gang is shaking up the Ransomware-as-a-Service market to empower affiliates." McAfee Enterprise ATR believes, with high confidence, that the Groove gang is associated with the Babuk gang, either as a former affiliate or subgroup. These cybercriminals are happy to put aside previous Ransomware-as-a-Service hierarchies to focus on the ill-gotten gains to be made from controlling victim’s networks, rather than the previous approach which prioritized control of the ransomware itself.

S5 Ep 204Taking a closer look at UNC1151.
Matt Stafford, Senior Threat Intelligence Researcher, from Prevailion joins Dave to talk about their work on "Diving Deep into UNC1151’s Infrastructure: Ghostwriter and beyond." Prevailion’s Adversarial Counterintelligence Team (PACT) used advanced infrastructure hunting techniques and Prevailion’s visibility into threat actor infrastructure creation to uncover previously unknown domains associated with UNC1151 and the “Ghostwriter” influence campaign. UNC1151 is likely a state-backed threat actor waging an ongoing and far-reaching influence campaign that has targeted numerous countries across Europe. Their operations typically display messaging in general alignment with the security interests of the Russian Federation; their hallmarks include anti-NATO messaging, intimate knowledge of regional culture and politics, and strategic influence operations (such as hack-and-leak operations used in conjunction with fabricated messaging and/or forged documents). PACT assesses with varying degrees of confidence that there are 81 additional, unreported domains clustered with the activity that FireEye and ThreatConnect detailed in their respective reports. PACT also assesses with High Confidence that UNC1151 has targeted additional European entities outside of the Baltics, Poland, Ukraine and Germany, for which no previous public reporting exists.

S5 Ep 203IoT security and the need for randomness.
Dan Petro, Lead Researcher, and Allan Cecil, Security Consultant, from Bishop Fox join Dave to share their research "You're Doing IoT RNG," that they presented at DefCon 29. There’s a crack in the foundation of Internet of Things (IoT) security, one that affects 35 billion devices worldwide. Basically, every IoT device with a hardware random number generator (RNG) contains a serious vulnerability whereby it fails to properly generate random numbers, which undermines security for any upstream use. In order to perform most security-relevant operations, computers need to generate secrets via an RNG. These secrets then form the basis of cryptography, access controls, authentication, and more. The details of exactly how and why these secrets are generated varies for each use. The research can be found here: You're Doing IoT RNG Learn more about your ad choices. Visit megaphone.fm/adchoices
S5 Ep 202Vulnerabilities in the public cloud.
Guest Ariel Zelivansky, Senior Manager of Security Research at Palo Alto Networks, joins Dave to discuss Unit 42's work on the first cross-account container takeover in the public cloud. The Unit 42 Threat Intelligence team has identified the first known vulnerability that could enable one user of a public cloud service to break out of their environment and execute code on environments belonging to other users in the same public cloud service. This unprecedented cross-account takeover affected Microsoft's Azure Container-as-a-Service (CaaS) platform. Researchers named the finding Azurescape because the attack started from a container escape – a technique that enables privilege escalation out of container environments. The research can be found here: What You Need to Know About Azurescape Finding Azurescape – Cross-Account Container Takeover in Azure Container Instances Note: Microsoft is a sponsor of the CyberWire, however, we cover them as we would any other company.

S5 Ep 201An IoT educational exercise reveals a far-reaching vulnerability.
Guest Jake Valletta, Director of Professional Services at Mandiant, joins Dave to talk about the critical vulnerability Mandiant disclosed that affects millions of IoT devices. Mandiant disclosed a critical risk vulnerability in coordination with the Cybersecurity and Infrastructure Security Agency (“CISA”) that affects millions of IoT devices that use the ThroughTek “Kalay” network. This vulnerability, discovered by researchers on Mandiant’s Red Team in late 2020, would enable adversaries to remotely compromise victim IoT devices, resulting in the ability to listen to live audio, watch real time video data, and compromise device credentials for further attacks based on exposed device functionality. These further attacks could include actions that would allow an adversary to remotely control affected devices.

S5 Ep 200A Google Chrome update that just didn't feel right.
Guest Jon Hencinski from Expel joins Dave Bittner to discuss his team's recent work on "Expel SOC Stops Ransomware Attack Aimed at WordPress CMS via Drive-By Download Disguised as Google Chrome Update." In July, 2021, Expel's SOC stopped a ransomware attack at a large software and staffing company. The attackers compromised the company’s WordPress CMS and used the SocGholish framework to trigger a drive-by download of a Remote Access Tool (RAT) disguised as a Google Chrome update. In total, four hosts downloaded a malicious Zipped JScript file that was configured to deploy a RAT, but we were able to stop the attack before ransomware deployment and help the organization remediate its WordPress CMS. Jon will walk us through what happened, how they caught it, and provide recommendations on how to secure your WordPress CMS.

S5 Ep 199Like a computer network but for physical objects.
Guest Ben Seri, Armis' VP of Research, joins Dave to talk about a set of remote code execution (RCE) vulnerabilities in the pneumatic tube system of Swisslog. Nine vulnerabilities in critical infrastructure used by 80% of major hospitals in North America. Swisslog’s Translogic Pneumatic Tube System (PTS), a solution that plays a crucial role in patient care, found vulnerable to devastating attack. Dubbed PwnedPiper, the vulnerabilities allow for complete take over of the Translogic Nexus Control Panel, which powers all current models of Translogic PTS stations. Older IP-connected Translogic stations are also impacted, but are no longer supported by Swisslog. The research can be found here: PwnedPiper Learn more about your ad choices.

S5 Ep 198Joker malware family: not a joke for Google Play.
Guest Deepen Desai, Zscaler's Chief Information Security Officer and VP Security Research & Operations, joins Dave to discuss their ThreatLabz team's research "Joker Joking in Google Play: Joker malware targets Google Play store with new tactics." Joker is one of the most prominent malware families targeting Android devices. Despite public awareness of this particular malware, it keeps finding its way into Google’s official application market by employing changes in its code, execution methods, or payload-retrieving techniques. This spyware is designed to steal SMS messages, contact lists, and device information, and to sign the victim up for premium wireless application protocol (WAP) services. Zscaler’s ThreatLabz research team has been constantly monitoring the Joker malware. Recently, they observed regular uploads of it onto the Google Play store. ThreatLabz notified the Google Android Security team, who have taken prompt action to remove the suspicious apps from the Google Play store. This prompted them to evaluate how Joker is so successful at getting around the Google Play vetting process. The team saw 11 different samples regularly uploaded to Google Play recently clocking 30k installs.

S5 Ep 197Exploring vulnerabilities of off-the-shelf software.
Guest Tomislav Peričin, Reversing Labs' Chief Software Architect and Co-Founder, joins Dave to discuss his team's research that addresses the importance of validating third-party software components as a way to manage the risks that they can introduce. Developing software solutions is a complex task requiring a lot of time and resources. In order to accelerate time to market and reduce the cost, software developers create smaller pieces of functional code which can be reused across many projects. The concept of code reuse is one of the cornerstones of modern software engineering and it is universally accepted that everybody should strive towards it. However, in addition to the positives, organizations need to be aware of the security risks introduced by such third-party components. The growing number of cyber incidents that target the software supply chain are focused on high-value target compromises. With the latest surge and public uproar, the US President Biden has issued the Executive Order on Improving the Nation’s Cybersecurity in order to create an institutional framework addressing these kinds of security risks.

S5 Ep 196You can add new features, just secure the old stuff first.
Guests Will Schroeder and Lee Christensen from SpecterOps join Dave to share the research they recently presented at Black Hat USA on the security of Microsoft's Active Directory Certificate Services. Their abstract: Microsoft’s Active Directory Public Key Infrastructure (PKI) implementation, known as Active Directory Certificate Services (AD CS), has largely flown under the radar of both the offensive and defensive communities. AD CS is widely deployed, and provides attackers opportunities for credential theft, machine persistence, domain escalation, and subtle domain persistence. We present relevant background on certificates in Active Directory, detail the abuse of AD CS through certificate theft and active malicious enrollments for user and machine persistence, discuss a set of common misconfigurations that can result in domain escalation, and explain a method for stealing a Certificate Authority’s private key in order to forge new user/machine “golden” certificates. By bringing light to the security implications of AD CS, we hope to raise awareness for both attackers and defenders alike of the security issues surrounding this complex, widely deployed, and often misunderstood system.

S5 Ep 195SideCopy malware campaigns expand and evolve.
Guest Asheer Malhotra, Threat Researcher of Cisco Talos Intelligence Group, joins Dave to discuss his team's research "InSideCopy: How this APT continues to evolve its arsenal." Cisco Talos has observed an expansion in the activity of SideCopy malware campaigns, targeting entities in India. In the past, the attackers have used malicious LNK files and documents to distribute their staple C#-based RAT. We are calling this malware "CetaRAT." SideCopy also relies heavily on the use of Allakore RAT, a publicly available Delphi-based RAT. Recent activity from the group, however, signals a boost in their development operations. Talos has discovered multiple new RAT families and plugins currently used in SideCopy infection chains. Targeting tactics and themes observed in SideCopy campaigns indicate a high degree of similarity to the Transparent Tribe APT (aka APT36) also targeting India. These include using decoys posing as operational documents belonging to the military and think tanks and honeytrap-based infections.

S5 Ep 194China's influence grows through Digital Silk Road Initiative.
Guest Charity Wright, Cyber Threat Intelligence Expert in Recorded Future's Insikt Group, joins Dave to discuss her research "China’s Digital Colonialism: Espionage and Repression Along the Digital Silk Road". Through the Digital Silk Road Initiative (DSR), announced in 2015, the People’s Republic of China (PRC) is building an expansive global data infrastructure and exporting surveillance technologies to dictators and illiberal regimes throughout the developing world, in some cases trading technology for access to sensitive user data and facial recognition intelligence. Domestically, China uses this type of technology to assert authority over its citizens, censor the media, quell protests, and systematically oppress religious minorities. Now, over 80 countries are enabled to do the same with Chinese surveillance technology.

S3 Ep 193Free malware with cracked software.
Guest Christopher Budd, Senior Global Threat Communications Manager at Avast, joins Dave to talk about some research his team did when they looked into a Reddit report saying their Avast folder was empty and other reports like it. The team found a new malware they’re calling “Crackonosh” in part because of some possible indications that the malware author may be Czech. Crackonosh is distributed along with illegal, cracked copies of popular software and searches for and disables many popular antivirus programs as part of its anti-detection and anti-forensics tactics.

S3 Ep 192Enabling connectivity enables exposures.
Guest Nathan Howe, Vice President of Emerging Technology at Zscaler, joins Dave to discuss his team's work, "2021 “Exposed” Report Reveals Corporate and Cloud Infrastructures More at Risk Than Ever From Expanded Attack Surfaces." The modern workforce has resulted in an increase of users, devices, and applications existing outside of controlled networks, including corporate networks, the business emphasis on the “network” has decreased and the reliance on the internet as the connective tissue for businesses has increased. Zscaler analyzes the attack surface of 1,500 organizations and identifies trends affecting businesses of all sizes and industries, across all geographies. Key findings include: The attack surface impact based on company size The countries with the greatest attack surface The industries that are most exposed The research can be found here: “Exposed”: The world’s first report to reveal how exposed corporate networks really are.

S3 Ep 191Dealing illicit goods on encrypted chat apps.
Guest Daniel Kats, Senior Principal Research Engineer at NortonLifeLock, joins Dave to discuss his team's work, "Encrypted Chat Apps Doubling as Illegal Marketplaces." Encrypted chat apps are gaining popularity worldwide due to their central premise of not sending user data to tech giants. Some popular examples include WhatsApp, Telegram and Signal. These apps have also been adopted by businesses to securely communicate directly to their users. Additionally, these apps have been instrumental to subverting authoritarian regimes. However, NortonLifeLock found that encrypted chat apps are also being used by criminals to sell illegal goods. Because content moderation is, by design, nearly impossible on these apps, they allow for an easy vector for dealers of illicit goods to communicate directly to customers without fear of law enforcement involvement.

S3 Ep 190Malware in pirated Windows installation files.
Guest Tom Roter from Minera Labs joins Dave to discuss his team research: "Rigging a Windows Installation." It is common knowledge that pirated software might contain malware, yet millions still put themselves and their devices at risk and download from dubious sources. It is even more surprising to see the popularity of torrented operating system installations, which are ranked at the top of most torrent tracker ranking lists. Today we will prove conventional wisdom right and show off a devious, yet clever attack chain employed by an infected Windows 10 image, frequently shared and downloaded by tens of thousands of users. Over the last year, numerous malicious PowerShell events popped up in our telemetry. The events caught our attention because a payload was being downloaded into the “C:\Windows” directory, which is usually well guarded under NTFS permissions, this implies that the attacker had very high privilege on the compromised system.

S3 Ep 189Exhibiting advanced APT-like behavior.
Guest Yonatan Striem-Amit joins Dave to talk about Cybereason's research "Prometei Botnet Exploiting Microsoft Exchange Vulnerabilities." The Cybereason Nocturnus Team responded to several incident response (IR) cases involving infections of the Prometei Botnet against companies in North America, observing that the attackers exploited recently published Microsoft Exchange vulnerabilities (CVE-2021-27065 and CVE-2021-26858) in order to penetrate the network and install malware. Yonatan shares his team's findings of the investigation of the attacks, including the initial foothold sequence of the attackers, the functionality of the different components of the malware, the threat actors’ origin and the bot’s infrastructure.

S3 Ep 188Primitive Bear spearphishes for Ukrainian entities.
Guests Gage Mele and Yury Polozov join Dave to talk about Anomali's research "Primitive Bear (Gamaredon) Targets Ukraine with Timely Themes." Anomali Threat Research identified malicious samples that align with the Russia-sponsored cyberespionage group Primitive Bear’s (Gamaredon, Winterflounder) tactics, techniques, and procedures (TTPs). Primitive Bear, known primarily to focus on Ukraine, has been very active in 2021. However, the themes of the samples Anomali found, as well as those shared by the security community, could also be used to target multiple former Union of Soviet Socialist Republic (USSR) countries. Anomali Threat Research found malicious .docx files being distributed by Primitive Bear, likely through spearphishing, that attempted to download remote template .dot files through template injection.

S3 Ep 186Bad building blocks: a new and unusual phishing campaign.
Guest Karl Sigler of Trustwave's SpiderLabs joins Dave Bittner to talk about their research: "Hidden Phishing at Free JavaScript Site". The research describes an interesting phishing campaign SpiderLabs encountered recently. In this campaign, the email subject pertains to a price revision, followed by some numbers. There is no email body, but there is an attachment about an ”investment.” The attachment’s convoluted filename contains characters the file-naming convention doesn’t allow, notably the vertical stroke, “|.” Even though "xlsx" is in the filename, double-clicking the attachment will prompt the user to open it with the default web browser. Thus, the file indeed appears to be an HTML document. Of course, it’s malicious. The research can be found here: HTML Lego: Hidden Phishing at Free JavaScript Site Learn more about your ad choices.

S3 Ep 185EtterSilent: a popular, versatile maldoc builder.
Guest Brandon Hoffman of Intel 471 joins Dave Bittner to share his team's research "EtterSilent: the underground’s new favorite maldoc builder". The cybercrime underground often mimics behaviors that we see in everyday facets of life. Intel 471’s latest discovery is an example of one of these patterns: when a product takes off in the marketplace, users will rush to obtain it and find unique ways to use it in order to fit their needs. The latest “product” is a malicious document builder, known in the underground as “EtterSilent,” that Intel 471 has seen leveraged by various cybercrime groups. As it has grown in popularity, it has constantly been updated in order to avoid detection. Used in conjunction with other forms of malware, it’s a prime example of how ease of use and a concentration of skill sets leads to a commoditization of the cybercrime economy.

S3 Ep 184Leveraging COVID-19 themes for malicious purposes.
Guest Joe Slowik joins us from DomainTools to discuss his team's research "COVID-19 Phishing With a Side of Cobalt Strike." Multiple adversaries, from criminal groups to state-directed entities, engaged in malicious cyber activity using COVID-19 pandemic themes since March 2020. Adversaries continue to leverage the pandemic, arguably the most significant issue globally as of this writing, in various ways. Yet the most persistent avenue remains using COVID-19 themes for building malicious document files. Examples include lures associated with Cloud Atlas-linked activity and broader targeting of health authorities. Given the continued significance of the pandemic and persistent use of pandemic themes by adversaries, DomainTools researchers continuously monitor for items leveraging COVID-19 content for malicious purposes. While conducting this research, DomainTools analysts identified an interesting malicious document with what appeared to be unique staging and execution mechanisms.

S3 Ep 183Jack Voltaic: critical infrastructure resiliency project, not a person.
Guest LTC Erica Mitchell from Army Cyber Institute joins us to talk about their infrastructure resiliency research project called Jack Voltaic. The Army Cyber Institute’s (ACI’s) Jack Voltaic (JV) project enables the institute to study incident response gaps alongside assembled partners to identify interdependencies among critical infrastructure and provide recommendations. JV provides an innovative, bottom‐up approach to critical infrastructure resilience in two unique ways. Whereas most federal efforts to improve resiliency focus on regional or multistate emergency response, JV focuses on cities and municipalities where critical infrastructure and populations are most heavily populated. Furthermore, JV deviates from other cybersecurity and national preparedness exercises in that it builds around areas of interest nominated by the participants. Although JV events include national-level capabilities and resources, they are conceptually driven by the concerns of the cities and their infrastructure partners. Through this approach, the ACI, the Army, and the Department of Defense (DoD) are able to harvest insights about potential roles, dependencies, partners, and support requests, while cities are able to discover potential capability gaps and expand their critical infrastructure information-sharing networks before a potential disaster strikes.

S3 Ep 182SUPERNOVA activity and its possible connection to SPIRAL threat group.
Guest Mike McLellan from Secureworks joins us to share his team's insights about SUPERNOVA and threat group attribution. Similarities between the SUPERNOVA activity and a previous compromise of the network suggest that SPIRAL was responsible for both intrusions and reveal information about the threat group. In late 2020, Secureworks® Counter Threat Unit™ (CTU) researchers observed a threat actor exploiting an internet-facing SolarWinds server to deploy the SUPERNOVA web shell. Additional analysis revealed similarities to intrusion activity identified on the same network earlier in 2020, suggesting the two intrusions are linked. CTU™ researchers attribute the intrusions to the SPIRAL threat group. Characteristics of the activity suggest the group is based in China.

S3 Ep 180Bulletproof hosting (BPH) and how it powers cybercrime.
Guest Jason Passwaters of Intel 471 joins us to discuss his team's research into bulletproof hosting (BPH). The research team at Intel 471 defined what a typical BPH service offers and how these services can be stopped in order to limit the damage they have on enterprises, businesses and digital society itself. They examined some popular malware families that actors host or leverage via BPH services. While much more goes into a cybercriminal’s full operation, it would be vastly more difficult to pull off without the ability to host malware and be free from impunity. Finally, they listed of some of the BPH providers that are firmly entrenched in the cybercrime underground and how they give support to other cybercriminal enterprises. By recognizing their behaviors, security teams can begin to take measures to figure out who the actors are, how they operate and what their infrastructure looks like. By doing so, organizations can begin to uncover ways to proactively counter maliciously-used infrastructure before criminals have a chance to launch their attacks.

S3 Ep 179Social engineering: MINEBRIDGE RAT embedded to look like job résumés.
Guest Deepen Desai joins Dave to talk about Zsaler's research "Return of the MINEBRIDGE RAT With New TTPs and Social Engineering Lures." In Jan 2021, Zscaler ThreatLabZ discovered new instances of the MINEBRIDGE remote-access Trojan (RAT) embedded in macro-based Word document files crafted to look like valid job resumes (CVs). Such lures are often used as social engineering schemes by threat actors. MINEBRIDGE buries itself into the vulnerable remote desktop software TeamViewer, enabling the threat actor to take a wide array of remote follow-on actions such as spying on users or deploying additional malware.The use of social engineering tactics targeting security teams appears to be on an upward trend.

S3 Ep 178Strategic titles point to something more than a commodity campaign.
Guests Gage Mele, Winston Marydasan, and Yury Polozov from Anomali join Dave to discuss their research into Static Kitten targeting government agencies in the UAE and Kuwait. Anomali Threat Research uncovered malicious activity very likely attributed to the Iran-nexus cyberespionage group, Static Kitten (Seedworm, MERCURY, Temp.Zagros, POWERSTATS, NTSTATS, MuddyWater), which is known to target numerous sectors primarily located in the Middle East This new campaign, which uses tactics, techniques, and procedures (TTPs) consistent with previous Static Kitten activity, uses ScreenConnect launch parameters designed to target any MOFA with mfa[.]gov as part of the custom field. Anomali's team found samples specifically masquerading as the Kuwaiti government and the UAE National Council respectively, based on references in the malicious samples.

S3 Ep 177Ezuri: Regenerating a different kind of target.
Guests Fernando Martinez and Tom Hegel from AT&T Alien Labs join Dave to discuss their team's research "Malware using new Ezuri memory loader." Multiple threat actors have recently started using a Go language (Golang) tool to act as a packer and avoid Antivirus detection. Additionally, the Ezuri memory loader tool acts as a malware loader and executes its payload in memory, without writing the file to disk. While this technique is known and commonly used by Windows malware, it is less popular in Linux environments.

S3 Ep 175BendyBear: difficult to detect and downloader of malicious payloads.
Guest Jen Miller-Osborn from Palo Alto Networks' Unit 42 joins us to discuss their research into BendyBear. Highly malleable, highly sophisticated and over 10,000 bytes of machine code. The code behavior and features strongly correlate with that of the WaterBear malware family, which has been active since as early as 2009. The malware is associated with the cyber espionage group BlackTech, which many in the broader threat research community have assessed to have ties to the Chinese government, and is believed to be responsible for recent attacks against several East Asian government organizations. Due to the similarities with WaterBear, and the polymorphic nature of the code, Unit 42 named this novel Chinese shellcode “BendyBear.” It stands in a class of its own in terms of being one of the most sophisticated, well-engineered and difficult-to-detect samples of shellcode employed by an Advanced Persistent Threat (APT).

Guest Hossein Jazi of Malwarebytes joins us to take a deep dive into North Korea's APT37 (aka ScarCruft, Reaper and Group123) toolkit. On December 7 2020 the Malwarebytes Labs threat team identified a malicious document uploaded to Virus Total which was purporting to be a meeting request likely used to target the government of South Korea. The meeting date mentioned in the document was 23 Jan 2020, which aligns with the document compilation time of 27 Jan 2020, indicating that this attack took place almost a year ago. The file contains an embedded macro that uses a VBA self decoding technique to decode itself within the memory spaces of Microsoft Office without writing to the disk. It then embeds a variant of the RokRat into Notepad. Based on the injected payload, the Malwarebytes team believes that this sample is associated with APT37. This North Korean group is also known as ScarCruft, Reaper and Group123 and has been active since at least 2012, primarily targeting victims in South Korea.

S3 Ep 172Shining a light on China's cyber underground.
Guest Maurits Lucas from Intel471 joins us to discuss his team's research into cybercrime in China. Data from Intel 471 show that the Chinese cybercrime underground proliferates through use of common methods or platforms, but behaves differently in large part due to the caution that actors take with regard to their identity. While the average citizen must follow the heavy handed nature of the government’s surveillance of cyberspace, Chinese threat actors take special precautions to protect their forums, TTPs and themselves. This leads to the Chinese cybercrime underground being disorderly when compared to others, particularly Russia, which tend to be much more organized.

S3 Ep 171Attackers (ab)using Google Chrome.
Guest Bojan Zdrnja of Infigo IS and a certified instructor at SANS Institute shares an incident he discovered where attackers were using a pretty novel way of exfiltrating data and using that channel for C&C communication. The code that was acquired was only partially recovered, but enough to indicate powerful features that the attackers were (ab)using in Google Chrome. The basis for this attack were malicious extensions that the attacker dropped on the compromised system.

S3 Ep 170Using the human body as a wire-like communication channel.
Guest Dr. Shreyas Sen, a Perdue University associate professor of electrical and computer engineering, joins us to discuss the following scenario:. Instead of inserting a card or scanning a smartphone to make a payment, what if you could simply touch the machine with your finger? A prototype developed by Purdue University engineers would essentially let your body act as the link between your card or smartphone and the reader or scanner, making it possible for you to transmit information just by touching a surface.

S3 Ep 169"Follow the money" the cybersecurity way.
Guest Joe Slowik joins us from Domain Tools to share their research "Current Events to Widespread Campaigns: Pivoting from Samples to Identify Activity" where they examined technical artifacts emerging around the 2020 conflict between Armenia and Azerbaijan in the Caucasus region. Cyber Threat Intelligence (CTI) practitioners can gain insight into adversary operations by tracking conflicts or geopolitical tensions. Similar to a “follow the money” approach in criminal investigations, looking at conflict zones can reveal cyber capabilities deployed as part of events —either by the parties to the conflict itself, or third parties interested in monitoring events for their own purposes. Based on precedent, analysts can identify developments in adversary operations and technical capabilities by tracking identifiers related to major events and conflict zones. Identifying capabilities deployed to take advantage of such items can yield insights into fundamental attacker tradecraft and behaviors, and enable defense and response for incidents which may strike far closer to home at a later date.

S3 Ep 168The Kimsuky group from North Korea expands spyware, malware and infrastructure.
Guest Yonatan Striem-Amit joins us from Cybereason to share their Nocturnus Team research into Kimsuky. The Cybereason Nocturnus Team has been tracking various North Korean threat actors, among them the cyber espionage group known as Kimsuky, (aka: Velvet Chollima, Black Banshee and Thallium), which has been active since at least 2012 and is believed to be operating on behalf of the North Korean regime. The group has a rich and notorious history of offensive cyber operations around the world, including operations targeting South Korean think tanks, but over the past few years they have expanded their targeting to countries including the United States, Russia and various nations in Europe.

S3 Ep 167Trickbot may be down, but can we count it out?
Guest Mark Arena from Intel471 joins us to discuss his team's research into Trickbot and its evolution from a banking trojan to a long-standing, most likely well-resourced operation that was taken down last year. Mark shares some insight into Trickbot's order of operations and what went on behind the scenes that his team working with Brian Krebs were able to discover. Since the separate and independent actions taken against Trickbot, Intel471 has observed successful disruption of its command and control infrastructure. However, the actors linked to Trickbot have not ceased their criminal activities. These actors have continued engaging in ransomware activity, using BazarLoader instead of Trickbot. Intel471 is unable to assess the long-term impact of the Trickbot disruption activity or whether Trickbot will continue to be used by cybercrime groups. This analysis covers the period from Sept. 22, 2020 until Nov. 6, 2020. The research can be found here: Trickbot down, but is it out? Learn more about your ad choices. Visit megaphone.fm/adchoices
S3 Ep 166Manufacturing sector is increasingly a target for adversaries.
Guest Selena Larson, senior cyber threat analyst at Dragos, Inc., joins us to discuss their research into recent observations of ICS-targeting threats to manufacturing organizations. Cyber risk to the manufacturing sector is increasing, led by disruptive cyberattacks impacting industrial processes, intrusions enabling information gathering and process information theft, and new activity from Industrial Control Systems (ICS)-targeting adversaries. Dragos currently publicly tracks five ICS-focused activity groups targeting manufacturing: CHRYSENE, PARISITE, MAGNALLIUM, WASSONITE, and XENOTIME in addition to various ransomware activities capable of disrupting operations. Manufacturing relies on ICS to scale, function, and ensure consistent quality control and product safety. It provides crucial materials, products, and medicine and is classified as critical infrastructure. Due to the interconnected nature of facilities and operations, an attack on a manufacturing entity can have ripple effects across the supply chain that relies on timely and precise production to support product fulfillment, health and safety, and national security objectives. Ransomware adversaries are adopting ICS-aware functionality with the ability to stop industrial related processes and cause disruptive – and potentially destructive – impacts. Dragos has not observed ICS-specific malware targeting manufacturing operations on the same scale or sophistication as that used in the disruptive TRISIS and CRASHOVERRIDE malware attacks that targeted energy operations in Saudi Arabia and Ukraine, respectively. However, known and ongoing threats to manufacturing can have direct and indirect impact to operations. This report provides a snapshot of the threat landscape as of October 2020 and is expected to change in the future as adversaries and their behaviors evolve.

S3 Ep 165Emotet reemerges and becomes one of most prolific threat groups out there.
Deep Instinct's Shimon Oren joins us to talk about his team's research on "Why Emotet's latest wave is harder to catch than ever before - Part 2." Emotet appears to have reemerged more evasive than before, this time with a payload delivered from a loader that security tools aren’t equipped to handle. Emotet, the largest malware botnet today, started in 2014 and continues to be one of the most challenging threats in today’s landscape. This botnet causes huge damage by spreading ransomware and info stealers to its infected systems. Recently, a rise in the number of Emotet infections was observed in France, Japan, and New Zealand. The high number of infections shows the effectiveness of the Emotet malware at staying undetected. Shimon joins us to discuss how Deep Instinct investigated the payload that was encrypted inside the loader, analyzes the next steps in the infection process, and discovers the techniques used to make this malware difficult to analyze.

S2 Ep 164Advertising Software Development Kit (SDK): serving up more than just in-app ads and logging sensitive data.
On August 24, 2020, Snyk announced the discovery of suspicious behaviors in the iOS version of a popular advertising SDK known as Mintegral. At that time, they had confirmed with partners in the advertising attribution space that at minimum, Mintegral appeared to be using this functionality to gather large amounts of data and commit ad attribution fraud. Their research showed that Mintegral was using code obfuscation and method swizzling to modify the functionality of base iOS SDK methods without the application owner’s knowledge. Further, their research proved that Mintegral was logging all HTTP requests including its headers which could even contain authorization tokens or other sensitive data. Since that time Mintegral announced that they were opening the source of their SDK to the market. While the SDK can only be downloaded by registered partners, a major game publisher shared the source code with Snyk for further analysis. They also continued their research by digging deeper into the Android versions of the SDK in which they hadn’t found similar behaviors at the time of the initial disclosure. This has resulted in some significant discoveries that necessitate an update to the previous disclosure. Additionally, Mintegral and the community at large have responded to the situation, and Snyk felt a summary of the events was a good way to finalize their research into this SDK. Joining us on Research Saturday to discuss their research is Snyk's Alyssa Miller.

S2 Ep 163Following DOJ indictment, a look back on NotPetya and Olympic Destroyer research.
From US Department of Justice: "On Oct. 15, 2020, a federal grand jury in Pittsburgh returned an indictment charging six computer hackers, all of whom were residents and nationals of the Russian Federation (Russia) and officers in Unit 74455 of the Russian Main Intelligence Directorate (GRU), a military intelligence agency of the General Staff of the Armed Forces. These GRU hackers and their co-conspirators engaged in computer intrusions and attacks intended to support Russian government efforts to undermine, retaliate against, or otherwise destabilize: (1) Ukraine; (2) Georgia; (3) elections in France; (4) efforts to hold Russia accountable for its use of a weapons-grade nerve agent, Novichok, on foreign soil; and (5) the 2018 PyeongChang Winter Olympic Games after Russian athletes were banned from participating under their nation’s flag, as a consequence of Russian government-sponsored doping effort. Their computer attacks used some of the world’s most destructive malware to date, including: KillDisk and Industroyer, which each caused blackouts in Ukraine; NotPetya, which caused nearly $1 billion in losses to the three victims identified in the indictment alone; and Olympic Destroyer, which disrupted thousands of computers used to support the 2018 PyeongChang Winter Olympics. The indictment charges the defendants with conspiracy, computer hacking, wire fraud, aggravated identity theft, and false registration of a domain name."

S2 Ep 162SSL-based threats remain prevalent and are becoming increasingly sophisticated.
While SSL/TLS encryption is the industry standard for protecting data in transit from prying eyes, encryption has, itself, become a threat. It is often leveraged by attackers to sneak malware past security tools that do not fully inspect encrypted traffic. As the percentage of traffic that is encrypted continues to grow, so do the opportunities for attackers to deliver threats through encrypted channels. To better understand the use of encryption and the volume of encrypted traffic that is inspected, Zscaler's research team, ThreatLabZ, analyzed encrypted traffic across the Zscaler cloud for the first nine months of 2020, assessing its use within specific industries. The study also set out to analyze the types of attacks that use encryption and the extent of the current risk. Returning to Research Saturday this week to discuss the report is Zscaler's CISO and VP of Security Research, Deepen Desai.

Encore: Using global events as lures for malicious activity.
The goal of malicious activity is to compromise the system to install some unauthorized software. Increasingly that goal is tied to one thing: the user. Over the past several years, we as an industry improved exploit mitigation and the value of working exploits has increased accordingly. Together, these changes have had an impact on the threat landscape. We still see large amounts of active exploitation, but enterprises are getting better at defending against them. This has left adversaries with a couple of options, develop or buy a working exploit that will defeat today's protections, which can be costly, or pivot to enticing a user to help you. In today's threat landscape, adversaries are always trying to develop and implement the most effective lures to try and draw users into their infection path. They've tried a multitude of different tactics in this space, but one always stands out — current events. Joining us on this week's Research Saturday from Craig Williams from Cisco's Talos Outreach team to walk us through how current events are used as lures.
