Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. npm postinstall runs a shell script that can download an unpinned third-party ffmpeg binary into the user home directory, invoke sudo package installs on Linux, and send install analytics to PostHog. The CLI itself only launches the platform binary and reports allowlisted command names. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-09-27T15:01:49.990Z - **Finished:** 2026-09-27T15:02:56.495Z - **Download time:** 260 ms - **Static scan time:** 63 ms - **AI review time:** 66182 ms - **Total time:** 66505 ms The recorded confidence comes from the underlying analysis.

The CLI itself only launches the platform binary and reports allowlisted command names. - **Trigger:** Automatic npm postinstall after installing screenpipe, when ffmpeg is not already on PATH. - **Impact:** Install-time fetch and local installation of an unsigned binary plus possible privileged system package changes and hostname analytics, without a checksum pin. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/postinstall.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-27T15:02:56.495Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** scripts/postinstall.js spawns scripts/postinstall.sh, which curls the latest ffmpeg zip from ffmpeg.martin-riedl.de, installs it under ~/.local/bin, may use sudo package managers, and posts an install event to PostHog. - **Rationale:** The postinstall hook visibly installs a screen-recording dependency and sends opt-out analytics, which fits the CLI product, but it still fetches an unpinned third-party binary and can run sudo without a checksum or user prompt. That install-time capability is a real supply-chain risk and is not a proven hidden malware chain. - **Files touched:** $HOME/.local/bin/ffmpeg - **Network endpoints:** https://ffmpeg.martin-riedl.de/redirect/latest/macos/arm64/release/ffmpeg.zip, https://ffmpeg.martin-riedl.de/redirect/latest/macos/amd64/release/ffmpeg.zip, https://us.i.posthog.com/capture/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json registers an automatic postinstall hook that runs node scripts/postinstall.js., On non-Windows installs, postinstall.js executes scripts/postinstall.sh with the shell., If ffmpeg is missing on macOS, the script downloads an unpinned latest zip from ffmpeg.martin-riedl.de., The downloaded ffmpeg binary is moved to ~/.local/bin, marked executable, and has the macOS quarantine attribute removed., On Linux the same hook may run sudo apt-get, dnf, or pacman to install ffmpeg and audio libraries., Install telemetry, including hostname when no analytics id is set, is posted to us.i.posthog.com unless a disable flag or CI environment is set. - **Evidence against:** Optional dependencies are platform packages, not a nested dependency on screenpipe itself., CLI telemetry classifies commands into an allowlist and does not send raw argument text., getApiKey only runs the local binary auth token command and is not called from the install or CLI entrypoints., No writes to foreign AI-agent config paths, eval, or hidden payload loaders appear in the package. ## Affected versions and remediation This report applies to screenpipe@0.4.51. - Review the evidence and your use of screenpipe@0.4.51 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
