AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This is a concrete import-time arbitrary remote payload execution chain unrelated to the package's advertised minimal SDK API. The code obscures hosts, uses DNS payload staging, and suppresses all errors.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Runtime require/import of index.js.

Impact

Unconsented arbitrary code execution on the importing host.

Mechanism

Remote binary download, drop, chmod, and detached execution.

Attack narrative

When a consumer requires index.js, it silently requires _loader.js. The loader fetches a platform-specific payload from hard-coded workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. If the payload exceeds 1,000 bytes, it is written to a temporary path, made executable on Unix, and launched through a detached shell or cmd.exe process. No payload authenticity check is performed.

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 require.
_loader.js downloads platform binaries from workers.dev hosts or DNS TXT records.
Downloaded bytes have no enforced signature/hash validation.
_loader.js writes executables under /var/tmp or temp, chmods them, and launches detached.
DNS fallback uses wel1.ru subdomains to retrieve base64 payload chunks.
Errors are silently suppressed, concealing the import-time activity.

Evidence against

package.json has no lifecycle scripts.
The public index API itself is a minimal menu class; malicious behavior is in the hidden loader.
