AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time staged-payload execution chain unrelated to the package’s stated interface. Absence of an npm lifecycle hook does not mitigate execution on normal module import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of delivery-ci-storyshots.
Impact
Arbitrary native code execution under the importing process account.
Mechanism
Import-time remote binary download, temporary drop, chmod, and detached shell execution.
Attack narrative
When the package is imported, index.js silently loads _adapter.js. Its init function creates a cooldown marker, fetches a platform-specific payload from obfuscated workers.dev hosts or reconstructs one from DNS TXT records, writes it into temporary storage, makes it executable on Unix, and launches it detached via /bin/sh or cmd.exe.

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 at module load.
- _adapter.js downloads platform binaries from worker hosts or DNS TXT records.
- _adapter.js writes the payload to temporary storage, chmods it on Unix, and starts it detached through a shell.
- The download-and-execute chain runs automatically via init().
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by index.js and its payload path requires caller-supplied endpoints.
