250,000 affected by data Breach at Texas hospital CISA says, "patch Citrix NetScaler bug by Thursday" Researchers uncover mining operation using ISO lures Get the show notes here: https://cisoseries.com/cybersecurity-news-texas-hospital-breach-cisa-orders-netscaler-patch-iso-file-rat-warning/ Huge thanks to our sponsor, ThreatLocker Security controls fail when they break the business. Successful teams phase in protections gradually — starting with visibility, then moving to enforcement. That approach allows organizations to reduce risk without overwhelming IT teams or disrupting critical workflows. Learn more at ThreatLocker.com

Apple pushes new patches over DarkSword FBI: US surveillance hack is major incident Cisco code stolen in Trivy-linked breach Get the show notes here: https://cisoseries.com/cybersecurity-news-apple-pushes-new-patches-over-darksword-fbi-us-surveillance-hack-is-major-incident-cisco-code-stolen-in-trivy-linked-breach/ Huge thanks to our sponsor, ThreatLocker Detection-based security assumes you'll catch an attack in time. Control-based security assumes you won't. That mindset shift is driving more organizations to focus on preventative controls — stopping unknown execution and unauthorized privilege elevation instead of relying solely on alerts after the fact.

HTTP client introduces malicious dependency TeamPCP testing the open source supply chain Claude source code leaked Get the show notes here: https://cisoseries.com/cybersecurity-news-axios-poisoned-teampcp-details-claude-code-leaked/ Huge thanks to our sponsor, ThreatLocker Least privilege isn't about distrusting users — it's about limiting blast radius. Many attacks succeed because malware inherits excessive permissions. Enforcing least privilege helps ensure that even if something goes wrong, attackers can't easily escalate access or move laterally across the environment. Learn more at ThreatLocker.com

FBI confirms theft of director's personal emails Lloyds customer data exposed in IT glitch Hundreds of valid API keys discovered on the Web Get the show notes here: https://cisoseries.com/cybersecurity-news-fbi-email-theft-lloyds-bank-glitch-api-keys-running-loose/ Huge thanks to our sponsor, ThreatLocker Most breaches don't start with a zero-day — they start because something unexpected was allowed to run. One way organizations reduce risk is by shrinking the attack surface: deciding what software should be allowed to execute and blocking everything else by default. Fewer unknowns means fewer opportunities for attackers. Learn more at ThreatLocker.com
