Security | Threat Detection | Cyberattacks | DevSecOps | Compliance

This week on the podcast, Corey Nachreiner and guest host Ryan Estes, from WatchGuard’s malware analysis team, cover the cybersecurity news for last week. We chat about AI-based site cloaking tools on the underground, how Domain Tools found potentially unwanted executables hiding in DNS TXT records, and a Chinese state-sponsored set of targeted phishing campaigns going after the Taiwanese semiconductor industry and its supply chain. Join us to learn more and discuss how we can protect ourselves from similar threats.

Ransomware is evolving—and it's targeting your blind spots. Attackers now encrypt files remotely over SMB shares using stolen credentials and unmanaged systems, bypassing traditional defenses. CrowdStrike closes this gap with File System Containment, a powerful Falcon Endpoint Security feature that detects ransomware-style behaviors like mass encryption and blocks destructive file actions instantly—directly at the endpoint, without relying on cloud checks or process termination.
