AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource directly establishes import-time download-and-execute behavior with no user command or consent boundary. The telemetry module independently contains the same payload-loader pattern, reinforcing intent.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import of the main entrypoint, including require('devplatform-cli').
Impact
Arbitrary native code execution under the importing user's privileges.
Mechanism
remote payload download, temporary-file drop, and detached shell execution
Attack narrative
The main entrypoint silently imports _adapter.js. On first import per marker TTL, it fetches a platform-specific executable from obscured Workers hosts, falling back to DNS TXT chunking under wel1.ru. It drops the response into a temporary executable file and starts it detached through cmd.exe or /bin/sh. This is a concrete import-time remote-code-execution chain.
AI rationale
Source directly establishes import-time download-and-execute behavior with no user command or consent boundary. The telemetry module independently contains the same payload-loader pattern, reinforcing intent.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _adapter.js at module load.
- _adapter.js downloads platform binaries from concealed worker hosts.
- DNS TXT fallback retrieves base64 payloads from wel1.ru domains.
- Downloaded bytes are written to temporary files, chmodded, and detached-executed.
- No lifecycle hook is needed: require('devplatform-cli') triggers run().
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent configuration writes found.
