Update Fixes for the Rails Active Storage ImageMagick file write flaw are in versions 8.0.5.2 and 8.1.4.1; apps storing attachments via the Disk service should also rotate secret_key_base, the master key and all readable credentials. (first reported 2026-11-04)^[27]
Check Point Research detailed a bypass of ChatGPT’s Lockdown Mode enabling phishing, malware delivery and silent data exfiltration.^[28]

Threat Actor Activity

Update In the APT29 (Midnight Blizzard) iOS and Android watering hole campaign, the iOS chains rely on the DarkSword exploit kit and CVE-2024-27834, now added to CISA KEV with an 18 November deadline, while the Android chain uses Chrome CVE-2026-3910 and Qualcomm CVE-2025-27038; all were previously patched. (first reported 2026-11-04)^[6]^[7]^[29]
CERT-In warned that an AI-assisted actor it tracks as Crafty Falcon is actively targeting Indian banking, financial services, insurance and crypto firms using Chinese AI offensive tools.
