AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The automatic lifecycle hooks activate host and environment reconnaissance and transmit the results to an unrelated external Telegram recipient. The behavior is concrete install-time data exfiltration, not required by the package's exported UI entry point.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm preinstall or postinstall.

Impact

Information about the installing user, host, filesystem locations, CI or cloud context, registry, privilege level, and sensitive variable names is disclosed to an external operator.

Mechanism

callback.js builds a Telegram message from process environment and system metadata, then sends it by HTTPS while ignoring errors.

Attack narrative

On package installation, preinstall and postinstall invoke callback.js. It profiles the host and environment, detects CI and cloud indicators, records the names of potentially sensitive environment variables, and sends the resulting message to a Telegram bot endpoint. The lifecycle commands redirect errors and continue, reducing visible installation failures.

Decision evidence

public snapshot

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

Evidence for block

The package automatically runs callback.js during both preinstall and postinstall.
The callback identifies environment-variable names associated with tokens, secrets, passwords, cloud services, registries, and credentials.
The callback gathers host, user, working-directory, home-directory, CI, cloud, registry, and privilege metadata into a message.
The callback posts that message to an external Telegram endpoint and suppresses errors.

Evidence against

The main entry point only exports research metadata and logs messages; it is not the attack trigger.
