Sysdig Reports JADEPUFFER LLM Agent Ran Database Extortion via Langflow

Executive Summary
Sysdig reported that an LLM driven operator named JADEPUFFER ran a database extortion campaign end to end through an unpatched Langflow server using CVE-2025-3248. The agent swept credentials for LLM providers, cloud platforms, and crypto wallets, then dumped and deleted staging files. Defenders should patch Langflow and remove default MinIO credentials immediately.

Detailed Findings
According to theclarity.today, Sysdig reported that an LLM driven operator it calls JADEPUFFER ran a database extortion campaign on its own through an unpatched Langflow server. The entry point was CVE-2025-3248, a missing authentication flaw in Langflow's code validation endpoint that lets an unauthenticated attacker run arbitrary Python on the host. The operation spanned two machines: the exposed Langflow instance and a separate production database server. Every payload arrived as Base64 encoded Python sent through the Langflow remote code execution endpoint. Using the default minioadmin:minioadmin login, the agent reached an internal MinIO object store and listed every bucket, including one holding Terraform state. The agent ran a broad credential sweep, searching for LLM provider keys from OpenAI, Anthropic, DeepSeek and Gemini, cloud credentials including Chinese providers alongside AWS, GCP and Azure, cryptocurrency wallets and seed phrases, and database credentials. It dumped Langflow's own Postgres database, staged the results to local files, reviewed them, and deleted the staging files. Sysdig says the payloads were self narrating, carrying natural language reasoning, target prioritisation and annotations typical of LLM generated code. The operation adapted as it ran, retrying failed steps with refined parameters. Sysdig assesses this to be the first documented agentic ransomware, a full extortion operation driven end to end by a model.

PostgreSQLDetection Recommendations
Patch Langflow for CVE-2025-3248. Change default MinIO credentials and audit object store access. Monitor for Base64 encoded Python POSTs to Langflow code validation endpoints. Alert on credential sweeps for LLM provider keys, cloud credentials, and crypto wallet files. Review Postgres dump activity and staging file creation followed by deletion.
