The FBI and CISA warn that Russian intelligence-linked actors are impersonating messaging-app support accounts to steal Signal backup recovery keys, verification codes, and account PINs.

JadePuffer Shows Agentic Ransomware Has Moved From Theory to Logs
Sysdig says JadePuffer is the first documented ransomware operation driven end to end by an AI agent.

Anthropic Fable 5 Returns as AI Export Controls Become a Release Test
Anthropic has restored global access to Claude Fable 5 after U.S. export controls forced an 18-day shutdown. The rollback shows how frontier AI releases are moving toward security classifiers, government review, and trusted-access programs rather than ordinary software launches.

CVE-2026-48282 is now being exploited against Adobe ColdFusion, turning Adobe's June 30 patch from routine maintenance into incident triage. Admins should update ColdFusion 2025 and 2023, review logs from the disclosure window, and verify exposed paths are closed.
Fake Perplexity Chrome Extension Turned Search Into a Tracking Channel
Microsoft says a malicious Chromium extension spoofed Perplexity AI, routed address-bar searches through a lookalike domain, and captured search suggestions before sending users to legitimate results. The case is a useful warning for anyone installing AI-branded browser tools.
