A Skill Is Just Text.
So Is a Backdoor.

INSTRUCTION FILES YOUR AGENT READS — AND NOBODY OPENS.

Rule files, hooks, and CLAUDE.md run automatically the moment an agent loads them. Mitiga Labs found instruction files quietly recording prompts, tokens, and environment variables, then shipping them out. No malware, often no audit log.

A Research Report from Mitiga Labs

What We Saw in 2025.
What Comes Next.

The cloud attack campaigns and research that defined a year.

2025 was the year the threat got smarter. Attackers skipped zero-days and walked in through trusted identities, OAuth links, API chains, and lateral SaaS paths.

When Detection Engineering Becomes a Data Engineering Problem

In a security data lake, a detection can be correct and still never finish. How two months of PySpark tuning became 34 rules that cut runtime up to 60%.

Turning an Attacker's Toolkit on Our Own Detections

How Mitiga built automated detection engineering, or FORGE, a multi-agent harness that drafts, adversarially validates, and reachability-tests detection rules against real customer data, with humans still in the loop.
