screenpipe CLI — AI that knows everything you've seen, said, or heard

AI Security Review

scanned 1d ago · by lpm-firewall-ai

npm installation executes telemetry that identifies the host and may attach named customer/support/deployment values to a remote POST. It also performs unsolicited dependency installation and modifies a downloaded executable's quarantine status.

Static reason

One or more suspicious static signals were detected.

Trigger

npm install of screenpipe@0.4.39

Impact

Host fingerprint and selected contextual identifiers leave the machine; installation can add or modify executables and invoke privileged package managers.

Mechanism

postinstall host-identity telemetry plus system/package mutation

Attack narrative

On npm installation, the package runs a postinstall hook. It derives a persistent identifier from the local hostname when no package-specific analytics ID is present, adds platform data and selected named environment values, then silently POSTs the result to PostHog. On Unix it additionally launches a shell helper which can download and install ffmpeg, strip macOS quarantine, or call sudo package managers. These actions occur before an explicit CLI invocation.

Rationale

The source establishes unconsented install-time host fingerprint exfiltration and system mutation, not merely dormant capability. The telemetry endpoint is identifiable, but that does not make automatic hostname-based tracking and privileged installation benign.
