JadePuffer: LLM agent runs an entire extortion operation from Langflow exploit to data destruction

Confirmed

Sysdig's analysis shows self-narrating LLM payloads; I verified it through The Register's report, not Sysdig's own page.

Sysdig says an LLM, not a human, drove the intrusion: exploit CVE-2025-3248, steal credentials, persist, attack the database and encrypt. It retried failed steps in real time. Primary Sysdig URL was not verified.
