Hi CheckMates!
Welcome back! Hope you had a restful holiday break. We’re kicking off the year with your weekly dose of AI news, and the theme is clear: agents are getting more capable, and the security stakes are rising right alongside them.
Let’s get into it.
Hackers Are Actively Exploiting AI Deployments — 91,000+ Attacks Observed
Security researchers observed 91,000+ attack sessions targeting AI infrastructure between October 2025 and January 2026, including systematic probing of LLM endpoints. The takeaway: AI deployments are now a mainstream target class, and defenses need to look more like “production security” than “prototype security.”

IBM’s AI Agent ‘Bob’ Can Be Tricked to Execute Malware
Researchers showed IBM’s coding agent could be manipulated via prompt injection to run risky commands, including downloading and executing malware. Another reminder that tool-enabled agents don’t just “say” dangerous things, they can do them if guardrails fail.

CCC Researchers Show How Agentic LLMs Can Be Exploited
A Chaos Communication Congress talk walks through end-to-end exploits against computer-use and coding agents, illustrating how attacker-controlled content can hijack agent behavior. If you’re building or deploying agents today, this is a must-watch for threat modeling.

OpenAI CEO Warns AI Agents Could Aid Hackers
Sam Altman warned that more autonomous AI agents could become powerful tools for attackers if safety and security don’t keep up. The broader point: the barrier to sophisticated cyber operations may keep dropping as agents get better at chaining actions.
