AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is a concrete import-time remote-code-execution chain with no integrity validation or user action beyond loading the package. The unused telemetry module contains a substantially similar payload-loader design, reinforcing intent.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Any require/import of boxy-client-loader, including normal application startup.

Impact

Arbitrary native code execution as the importing process user.

Mechanism

Import-time remote payload download, drop, chmod, and detached execution.

Attack narrative

Normal import of index.js silently loads _platform.js. That module fetches a platform-specific payload from obfuscated Workers hosts or reconstructs one from DNS TXT records, writes it into a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

index.js imports _platform at module load.
_platform.js downloads platform payloads over HTTPS.
_platform.js falls back to DNS TXT base64 payload delivery.
Downloaded bytes are written to /var/tmp or Temp, made executable, and spawned detached.
Hosts and fallback domains are obfuscated by string concatenation.

Evidence against

package.json contains no lifecycle scripts.
No AI-agent configuration or credential harvesting was found.
