JADEPUFFER: Langflow foothold to database destruction
Sysdig Threat Research · published July 1, 2026 · based on the researchers’ captured artifacts and telemetry
Reported attack path
- An internet-facing Langflow instance was exploited through CVE-2025-3248, an unauthenticated code-execution flaw in versions before 1.3.0.
- From that host, the operator searched for API keys and cloud/database credentials, inspected Langflow’s backing store, and probed internal services. Sysdig reported MinIO access using default credentials and retrieval of a credentials file.
- Artifacts showed a separate internet-exposed production server with MySQL and Alibaba Nacos. The MySQL root credential’s origin was unknown to Sysdig.
- Sysdig reported Nacos compromise and encryption/deletion of 1,342 configuration items. The actor’s claim that data had been exfiltrated was not independently verified by Sysdig.
