The count by type
The tracker uses six types. Here is what each means and how many entries fell into it so far.
| Type | Entries | What it covers |
|---|---|---|
| AI-run attack | 0 | An intrusion where agents or models did real operational work |
| Critical vuln | 0 | A severe flaw disclosed and fixed, no confirmed exploitation yet |
| Breach | 0 | A company's systems or customer data were accessed |
| Supply chain | 0 | A package, release or update channel shipped malicious code |
| Exploited | 0 | A bug with confirmed attacks in the wild |
| Agent incident | 0 | An AI agent caused harm or broke a control by itself |
Each entry has a status: "Confirmed" (the company, an agency or a named research team said so) or "Reported" (one vendor's research, not yet corroborated).

What the month shows
It is too early to say. With no entries, there is no pattern to report. We will write this section once the tracker holds enough incidents to support one.
What to do now
- Rotate secrets you have not rotated since October. The October list showed stolen tokens, app credentials and unrotated passwords as the usual way in.
- Cap and scope every AI key. Set a spend limit and the narrowest permission each key needs, so one leak does not become an unlimited bill.
- Pin packages and images. Use exact versions and digests, and delay adopting new releases by a day or two where you can.
- Lock down publishing. Use short-lived tokens, protect release workflows, and review any new workflow file a token pushes.
- Watch what agents can reach. Give agents narrow cloud roles, no standing production keys and a log you actually read.
