AI Security Review

scanned 1mo ago · by lpm-firewall-ai

Installing the package runs a shell script that downloads and installs a redirected binary or invokes privileged system package installs. It also transmits install telemetry containing a host identifier.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation triggers postinstall.

Impact

A redirected download can replace a user-local executable; Linux installs can prompt for elevated privileges; host identity data is sent off-device.

Mechanism

Automatic remote binary installation, privilege-requesting dependency installation, and telemetry transmission.

Attack narrative

A normal npm install invokes the package shell installer. On macOS it fetches a redirected archive without an integrity check, moves its executable into the user's local binary directory, and removes its quarantine attribute. On Linux it attempts sudo package-manager installation. The install path also submits a hostname-based identifier and optional environment-derived identifiers to PostHog. Reviewer-directed AI instructions appear in source comments.

AI rationale

The automatic lifecycle hook makes unverified remote binary placement and privileged system mutation without a separate user command. This concrete install-time behavior, host telemetry, and reviewer manipulation justify blocking publication.
