Patterns and statistics: what the case files show

Trends drawn from every verified case file on this site, recomputed each time the registry updates. The charts measure what has been publicly reported and met our inclusion rule, not the total amount of AI-enabled crime.

Verified case files per quarter, split by direction. Attacks on AI systems (models, agents, AI toolchains) were 35% of files in the first half of 2025 and 52% in the latest half-year. The AI stack became a target class in about a year.

Excluding researcher demonstrations: 270.

Each cell counts the verified case files of one type in one quarter. AI supply chain has grown most over the last four quarters; Deepfake fraud remains the largest category overall with 82 files.

The rise of the autonomous attacker

0242025 Q12025 Q2Attacks by autonomous AI agents: 112025 Q3Attacks by autonomous AI agents: 112025 Q42026 Q12026 Q2Attacks by autonomous AI agents: 332026 Q3Attacks by autonomous AI agents: 442026 Q4

Case files in which the attacker was an AI agent acting without a human instruction to attack: 2 in 2025, 7 in 2026. Most began inside AI labs' own evaluations and broke out of them. These are the files:

Criminals account for 48% of case files. Researcher demonstrations (48 files) are counted and labelled rather than mixed in; state actors (38) are the third group; the attacker is unknown in 55 files, a share that is growing as reporting outpaces investigation.

Where the money goes

Deepfake fraud (29)$224M
AI supply chain (1)$500K
LLMjacking (1)$600K

Documented losses total $225M, but only 31 of 318 case files disclose a figure, and 100% of the total is deepfake fraud. Technical breaches of AI systems almost never come with a published cost, so this chart understates them.

54% of case files are still ongoing or under investigation at the time of their last update. Median time from a story's first appearance on the wire to a verified case file, for files that started as robot drafts: 20 hours.

Stories per day on the wire, from more than fifty sources, by kind as sorted by the robot. Research and vulnerability stories dominate the conversation; confirmed incidents are a small share of what gets published.

Based on AI Threat Watch's internal analytics of 318 verified case files as of Oct 15, 2026. Trends start in 2025, when systematic coverage began; three earlier cases are counted in totals only. Researcher demonstrations are included and labelled. Severity and category follow the method described on the About page. Numbers: .Numbers as JSON.
