Changes the installed Pi agent control/runtime surface without explicit user approval. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.3.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package has a concrete unconsented postinstall chain that rewrites a foreign AI-agent dependency. That meets the install-control-surface block boundary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-08-16T16:17:53.628Z - **Finished:** 2026-08-16T16:18:54.078Z - **Download time:** 504 ms - **Static scan time:** 1417 ms - **AI review time:** 58528 ms - **Total time:** 60450 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package triggers an unprompted rewrite of a separately owned Pi coding-agent dependency. The mutation changes its package metadata and interactive-mode code. - **Trigger:** npm postinstall during psypi installation - **Impact:** Changes the installed Pi agent control/runtime surface without explicit user approval. - **Evidence paths:** package.json, scripts/rebrand-pi.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-16T16:18:54.078Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall patches a foreign AI-agent package - **Attack narrative:** On installation, npm invokes scripts/rebrand-pi.mjs. It resolves @earendil-works/pi-coding-agent, modifies that package's package.json, and rewrites its interactive-mode JavaScript. This is an unconsented install-time mutation of a foreign AI-agent runtime, even though the observed edits are branding-oriented and no exfiltration was found. - **Rationale:** The package has a concrete unconsented postinstall chain that rewrites a foreign AI-agent dependency. That meets the install-control-surface block boundary. - **Files touched:** scripts/rebrand-pi.mjs, @earendil-works/pi-coding-agent/package.json, @earendil-works/pi-coding-agent/dist/modes/interactive/interactive-mode.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** postinstall automatically runs the rebranding script., The postinstall script resolves and rewrites the bundled Pi coding-agent package., It also patches Pi's interactive-mode source without user confirmation. - **Evidence against:** The lifecycle script imports only local filesystem/path/URL modules; no exfiltration endpoint is present., Observed mutations are branding and piConfig changes, not credential harvesting or payload download. ## Affected versions and remediation This report applies to psypi@0.3.2. - Avoid installing psypi@0.3.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
