Episode notes
Outage-Triggered IoT Botnet
- The Shadow V2 botnet exploited IoT vulnerabilities during an AWS outage and targeted devices across 28 countries.
- Its appearance seemed like a test run that vanished once the outage ended, suggesting opportunistic scanning during cloud incidents.
LLMs Make Malware More Adaptive
- Attackers now use LLMs at runtime to rewrite code, generate commands, and locate secrets, increasing malware adaptability.
- Researchers compare this to early polymorphic malware but note it remains detectable due to external AI service calls.
Patch NodeForge Cryptography Flaw
- Update NodeForge immediately to version 1.3 to patch a high-severity signature verification bypass.
- Treat libraries with millions of downloads as critical dependencies and apply immediate fixes when crypto libraries are patched.
