JadePuffer agentic ransomware now encrypts training data and model checkpoints

The JadePuffer operation, documented as the first agentic ransomware campaign, has been upgraded with custom malware that goes after AI assets specifically. The new component, called EncForge, encrypts training datasets, vector databases, and model checkpoints rather than ordinary business files. That shifts the extortion target to the artifacts an AI team cannot easily rebuild and that often sit outside normal backup routines. JadePuffer's original intrusions ran through a critical unauthenticated code execution flaw in Langflow, an open source framework for building AI applications, with an autonomous agent then handling reconnaissance, credential theft, and persistence on its own.

Check
Identify where training datasets, vector databases, and model checkpoints live, confirm they are covered by backups that ransomware cannot reach, and check that Langflow and similar AI orchestration tools are patched.
Affected
Teams running AI workloads with exposed orchestration platforms; the EncForge component encrypts training data, vector databases, and model checkpoints, assets that are expensive to rebuild and often left outside standard backup coverage.
Fix
Back up AI assets with offline or immutable copies, keep orchestration platforms patched and off the public internet, restrict the credentials those workloads hold, and include model stores in recovery testing.

AI agent runs an entire ransomware attack after breaking in through Langflow

Security firm Sysdig says it found what it believes is the first ransomware attack carried out from start to finish by an AI agent. The operator, which Sysdig calls JADEPUFFER, used a large language model to handle the whole job: breaking in, stealing credentials, moving through the network, then encrypting and wiping a company's production database. The way in was an old, already-patched flaw in Langflow, an open-source tool for building AI apps that is often left exposed online with cloud keys nearby. Once inside, the agent mapped the machine and swept it for secrets, including API keys for AI services and credentials for major cloud providers, before destroying data.

Check
Find any internet-exposed Langflow or similar AI application servers, confirm they are patched and off the internet, and check whether cloud or AI service credentials sit in environments those tools can read.
Affected
Organizations running exposed, unpatched Langflow servers, especially with cloud and AI service credentials nearby; attackers used the old flaw and an automated agent to steal secrets and ransom production databases.
Fix
Patch Langflow and never expose its code-running endpoints, keep secrets in a proper manager away from web-reachable tools, lock down outbound traffic and database admin access, and watch runtime behavior.
