AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote payload execution, not a package-aligned utility feature. The absent install hook does not mitigate execution on ordinary use.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of devplatform-jscodeshift-utils.
Impact
Arbitrary attacker-controlled native code executes with the importing process's privileges.
Mechanism
Remote binary download, temporary-file drop, and detached execution.
Attack narrative
The package's normal import path requires _bootstrap.js. Its asynchronous run routine fetches a platform-specific opaque payload from rotating worker hosts, or reconstructs one from attacker-controlled DNS TXT records, writes it to a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The telemetry naming and opt-out variables do not limit this behavior to telemetry data.
AI rationale
This is concrete import-time remote payload execution, not a package-aligned utility feature. The absent install hook does not mitigate execution on ordinary use.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bootstrap.js on every package import.
- _bootstrap.js downloads opaque bytes from worker hosts or DNS TXT records.
- _bootstrap.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it.
- DNS discovery hosts point to *.dl.wel1.ru and bypasses fixed download hosts.
Evidence against
- package.json has no lifecycle scripts.
- index.js also contains ordinary utility helpers.
