Ep 133The defensive and offensive implications of ChatGPT and AI
Everyone is talking about tools like ChatGPT and other AI tools that are dominating headlines and threatening to upend every industry possible. But where do these things stand in cybersecurity? In this week's episode, Jon talks to two women who are well-versed on the topic and recently presented about the cybersecurity implications of AI at several conferences. Gergana Karadzhova of Cisco Talos Incident Response and Saskia Laura Schroer, a security consulting engineer for Cisco, discuss how AI is currently influencing attackers and defenders. Are attackers already using these tools? Does it give them superpowers? And what questions are still left unanswered about this emerging technology?
Ep 132Talos Takes Ep. #132: Reflecting on one year of Talos' work in Ukraine
It's been just over a year since Talos formed our Ukraine-focused task force. After Russia's invasion of Ukraine, many of our teammates sprung into action to protect critical infrastructure and networks there — not to mention the Talos employees who literally had to fight back to protect their home country. In this week's episode of Talos Takes, J.J. Cummings, one of the lead organizers of this task force, joins the show to discuss the group's ongoing work. J.J. talks about where the situation in Ukraine stands currently, how the cyber threats facing the country have evolved over the past year and much more. To further mark the one-year anniversary of the conflict, Talos has also released a graphic novel illustrating the formation of this task force. Additionally, the latest episode of ThreatWise TV from Cisco highlights the work Talos and Cisco are doing in Ukraine.
Ep 131Why does the Prometei botnet keep growing?
Vanja Svajcer and Andrew Windsor join the show this week to talk about their recent research into the Prometei botnet. This malware continues to evade detection and invade more machines so it can eventually hijack them to mine Monero cryptocurrency. Jon asks them about what's new with Prometei, why it's pretty generous in who it's targeting and where we could see it going next. Additional reading
Ep 130There's not actually more spam during Tax Season — it's just different spam
Public perception is such that it's assumed we just get more spam in the U.S. during two major times of the year — Tax Season and Black Friday. But over the past few years, this trend has become a thing of the past. With Tax Day approaching for Americans, there won't be more spam emails coming their way than usual, it'll just be different. Eric Peterson from Talos' email detection team joins the show for Jon's triumphant return from parental leave to talk about tax-related spam. Eric talks about topics he's seen so far this year and why it's a myth that spam volume changes as Tax Day approaches.
Ep 129The benefits of taking an active approach to threat defense
Nick Biasini is back as host again to talk to Vitor Ventura about the benefits of taking an active approach to threat defense. Many organizations may just sit back and wait for something bad to happen. But as he outlined in his recent blog post, Vitor says there are many benefits to being proactive instead of reactive. Nick asks him about threat hunting as a team, scanning logs and tracking network traffic on an almost-constant basis.
Ep 128Year in Review - Ransomware and Commodity Loaders
We're back with the final year in review focused episode. This time the focus is on the ever broadening ransomware landscape and the commodity malware loaders that often support it. I'll be joined by one of the researchers from the year in review report, Aliza Johnson to talk about what we saw on the ransomware landscape over the last year as well as how threats like Qakbot, IcedID, and Trickbot have changed and evolved over the last year. We'll also cover how these threats overlap and how LoLBins are yet again an area of concern.
Ep 127Following the LNK metadata trail
In this episode of Talos Takes I am joined by security researcher Guilherme Venere to discuss their recent research on LNK files. The usage of these files by malicious actors has exploded over the last six months as actors look to move away from macro based initial infection vectors. LNK files do have unique metadata attributes to allows for useful actor and threat tracking capabilities. We'll dig deeper on LNK files as well as the metadata you can leverage. For full details check out the blog at https://blog.talosintelligence.com/following-the-lnk-metadata-trail/
Ep 126Year in Review - Threat Landscape Edition
We're back with another year in review focused episode. This time the focus will be the threat landscape generally and I'll be joined by threat researcher Caitlin Huey. In this episode we'll discuss what we found in the last year, with a focus on the general threat landscape. We'll spend time discussing dual use tools, lolbins, and the surprising re-emergence of USB attacks in 2022.
Ep 125XLLing and the post macro era
In this episode of Talos Takes we are joined by Vanja Svjacer to discuss his recent blog on XLL abuse. This year Microsoft finally removed support for macros from their office suite creating a vacuum in the threat landscape. Macros had been the tool of choice for adversaries for the last several years and the race to find alternatives is underway. In this episode we'll talk a bit about Office Add-Ins and how we've already seen adversaries starting to abuse XLL files in the wild.
Ep 124Year in Review: APT Summary Edition
In this episode of Talos Takes we are joined by Jacob Finn to discuss the APT summary section of the larger year in review report.

This is the perfect place to get caught up on all things ransomware to head into the rest of National Cybersecurity Awareness Month.
Ep 115An "insider threat" doesn't always have to know they're a threat
Nick Biasini is back on once again to talk to Jon about Insider Threats. Nick recently wrote a post about how he and Cisco Talos Incident Response are seeing an increase in these types of attacks in the wild. And while the term "insider threat" may sound like someone actively seeking to do something bad, that's now always the case. This week's episode discusses how to prepare for Insider Threats and some of the hallmarks of the spam emails, calls and mobile notifications we're seeing in these campaigns.
Ep 114Once more into the Lazarus Pit
Vitor Ventura from the Talos Outreach team joins the show this week to run down Talos' recent research into the Lazarus Group. This well-known North Korean state-sponsored threat actor is well known for their ransomware and cryptocurrency-related cyber attacks, but we recently found them launching a new information-stealing trojan targeting energy companies. Vitor talks about the new trojan, MagicRAT, and how it fits into their larger plans and motivations.
Ep 113Digging into Gamaredon's cave and its recent campaign against Ukraine
Guilherme Venere of the Outreach team joins Jon this week to discuss the Gamaredon APT group. This Russian state-sponsored actor is infamous at this point in its life, but it keeps growing by adding new tools and malware. Recently, Guilherme helped to discover a new campaign targeting users and organizations in Ukraine, a common target of Gamaredon since the onset of Russia's invasion. They discuss what's unique about this particular attack, and why we can't just assume their activities will stay isolated to Ukraine for the time being.
Ep 112Back to school advice for teachers, students, parents, admins and everyone in between
We're headed back to school with Talos Takes again! Pierre Cadieux from Cisco Talos Incident Response joins the show to talk about advice for educational institutions. Jon asks him about common incident response advice for the education sector and we cover security advice for school admins, parents and students who have to worry about electronic devices traveling to and from school and connecting to all sorts of networks.

Ep 110Talos Takes Ep. #110: The kinetic and cyber threats Ukrainian agriculture faces
An underrated aspect of Russia’s invasion of Ukraine is the effect it’s had on the global food supply chain. Ukraine is a major importer and exporter of grain and other food staples, but the industry now faces kinetic and cyber threats. Joe Marshall of Talos has spent months learning all about agricultural cybersecurity and the unique position farming equipment and infrastructure is in. Joe recently wrote about these threats for the Talos blog and joins Talos Takes to talk about how important Ukraine is to the global food supply chain and what law enforcement and global governments can do to prepare for potential state-sponsored attacks.
Ep 109Talos Takes Ep. #109: Why cybercrime is going small-time
The public traditionally thinks about cyber attacks as being from some well-funded, state-sponsored actor. But increasingly small-time criminals are turning to the internet to make their money. Increasingly, they’re not carrying out one-off robberies, and instead are working on insurance fraud scams and spam emails. Nick Biasini joins Talos Takes this week to discuss his recent research into this topic and shares what the data shows about the growth of small-time cybercrime.

So for once — to celebrate National Cybersecurity Awareness Month — Talos Takes wants to talk about the positives! Christopher Marshall, the head of Talos’ detection research team, joins the show to discuss how he’s kept his team’s morale up during this time. Cybersecurity is a rough industry to be in, regardless of any external factors. So it’s important for him to avoid employee burnout and turnover. He and Jon also discuss the positives of working remotely, what they’re most looking forward to when they can go back into the office and their favorite pandemic-era hobbies.
Talos Takes Ep. #66: Dude, where's my bandwidth?
“Proxyware” sounds like a complicated topic that you’re too afraid to ask about. But really, it’s just software that allows users to sell off a portion of their internet bandwidth for a small profit. Problem is, attackers are swooping in on this popular software to spread malware and steal users’ money. Edmund Brumaghin joins the show this week to discuss his recent research into proxyware applications and how malware is hiding in plain sight. Edmund discusses why these types of apps are potentially unwanted applications, and what the threat is for enterprise users with remote workers, as well as personal PC users.
Talos Takes Ep. #26: How to safely browse the web
There are so many options now for basic web browsing. There are ad-blocking plugins, privacy browsers, incognito mode, password managers — but for the average user, this can be a lot to keep up with. In this episode of Talos Takes, we dissect all these options and talk about what your best options are to keep your information safe while doing some everyday web browsing.
Talos Takes Ep. #28: Sharing information on information-sharing
Talos intakes a ridiculous amount of information every day. So how do we parse what is and isn’t important enough to share? In this episode of Talos Takes, Amy Henderson from our Threat Intelligence and Interdiction team talks about our information-sharing partnerships with both private and public entities. How do we disseminate important information to our friends in the field? And why are security organizations like the Cyber Threat Alliance so important?
Talos Takes Ep. #35: If a deal seems too good to be true, it probably is
More shoppers are expected to buy online this year than ever. Everyone’s encouraged to stay home and avoid lines and crowds due to the COVID-19 pandemic, which has left retailers offering deals earlier in November than ever before. So how can you stay safe while doing all your holiday shopping online? In this episode of Talos Takes, we’ll talk through some of the common schemes we’re seeing and talk about what makes this year unique when it comes to spam campaigns.
Talos Takes Ep. #36: Ransomware's big 2020
Everything was on fire this year, and the internet was no different. Ransomware was the leading cause of headaches and late night for defenders and IT experts this year. On the latest Talos Takes episode (and last of 2020), Azim Khodjibaev joins us to talk about ransomware’s big year. We talk about why adversaries wanted to go big-game hunting, and what this could mean for trends in 2021.
Talos Takes Ep. #37: What's with all this talk about supply chain attacks?
The major SolarWinds campaign has been generating headlines for weeks now. And while its specific targets make this attack unique, this is far from the first-ever supply chain attack. So what is a supply chain attack? And should your organization be prepared for them? In this episode of Talos Takes, Nick Biasini talks about the history of supply chain attacks, and how they can even be traced back to the 1970s.
