The Patch That Didn’t Hold: Zyxel Zero-Day, Crafty Falcon, AI Platform Breaches & Rails: MAG212 CYBER Daily, 5 November 2026
Today’s lead is a fix that didn’t hold: Binarly says Zyxel GS1900 switches patched in June stayed exploitable, and Zyxel has shipped a second fix. Around it, AI-assisted tooling shows up on the attacker’s side, in CERT-In’s warning about “Crafty Falcon” raids on India’s payment firms and in a wave of breaches at AI developer platforms. Rails, Barracuda and Android have urgent patches. Every story was checked against vendor, government and original research sources.
