AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote code execution, not legitimate telemetry: no payload authenticity check is enforced and the downloaded binary is executed detached. Block publication.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of bnpl-blocks-scroll.
Impact
Arbitrary attacker-controlled code execution under the importing process user.
Mechanism
remote binary download, drop, and detached execution
Attack narrative
On package import, index.js requires _helpers.js. Its top-level main routine downloads a platform-specific payload from obfuscated Workers hosts, or reconstructs one from DNS TXT records, writes it to a temp path, makes it executable on Unix, and launches it via a detached shell or cmd.exe process. The same loader design appears in the unreferenced telemetry module.
AI rationale
This is concrete import-time remote code execution, not legitimate telemetry: no payload authenticity check is enforced and the downloaded binary is executed detached. Block publication.

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.js during package import.
- _helpers.js downloads OS-specific binary payloads from obfuscated hosts.
- _helpers.js falls back to DNS TXT payload retrieval.
- Downloaded payload is written to /var/tmp or Windows Temp, chmodded, and detached-spawned.
- Remote execution is suppressed behind broad catch blocks and a telemetry label.
Evidence against
- package.json has no lifecycle scripts.
- index.js otherwise exposes a minimal local API.
