Sysdig's Threat Research Team documented the first campaign on July 1 and the second on July 20. The entry point never changed, but the payload changed completely.
Both ran through CVE-2025-3248, a missing-authentication flaw in Langflow's code-validation endpoint that lets anyone reaching the server execute Python on it. In the first, the agent improvised, encrypting 1,342 Alibaba Nacos configuration items with MySQL's own encryption function and dropping the tables. In the second, it staged ENCFORGE, a compiled Go binary sweeping roughly 180 file extensions.
