AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has no install hook, but its normal import path performs concealed download-and-execute behavior. This is concrete arbitrary code execution, not package-aligned Sentry telemetry.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Runtime import or require of devplatform-spa-plugin-sentry
Impact
Arbitrary code execution as the importing process user.
Mechanism
remote payload download, temporary-file drop, and detached execution
Attack narrative
Requiring index.js silently requires _helpers.js. Its async main routine selects a platform payload, fetches it from rotating Workers hosts or reconstructs it from DNS TXT records, writes it to a temporary directory, makes it executable on Unix, and starts it detached via shell or cmd.exe. No integrity validation or user action is required.
AI rationale
The package has no install hook, but its normal import path performs concealed download-and-execute behavior. This is concrete arbitrary code execution, not package-aligned Sentry telemetry.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _helpers on every package import.
- _helpers.js downloads platform-specific bytes over HTTPS, with DNS TXT fallback.
- _helpers.js writes the fetched payload to /var/tmp or Windows Temp, chmods it executable, then launches it detached.
- Downloads use unrelated Workers and .ru discovery hosts and are hidden behind telemetry naming/empty logging.
Evidence against
- package.json has no lifecycle scripts.
- The exported API itself is a minimal local configuration class.
