An AI agent just ran a ransomware attack completely on its own. No human involved. This might be the scariest AI story of 2026 and barely anyone's talking about it.

No human clicked. No human decided. The AI planned it, executed it, and encrypted the data — start to finish.
Security researchers documented it. It's called JADEPUFFER, and it's officially the first ransomware attack run entirely by an autonomous AI agent, hitting over a thousand database records.
We've spent years debating "can AI write good code." Wrong question the whole time.
The real question was always: what happens the moment AI can act instead of just answer?
That future didn't arrive with a warning. It arrived quietly, this month.
