A package installation modifies a foreign AI-agent installation surface and persistent user configuration without a separate user command. - **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:** 1.0.82 - **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. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes the user environment and installs a separate AI-agent CLI globally. It also persists PATH changes and replaces an application bundle in the user's Applications directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-20T08:11:32.179Z - **Finished:** 2026-09-20T08:20:37.817Z - **Download time:** 501 ms - **Static scan time:** 74 ms - **AI review time:** 545062 ms - **Total time:** 545638 ms The recorded confidence comes from the underlying analysis.

It also persists PATH changes and replaces an application bundle in the user's Applications directory. - **Trigger:** npm installation runs the postinstall script. - **Impact:** A package installation modifies a foreign AI-agent installation surface and persistent user configuration without a separate user command. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js - **Review source:** ai\_review - **Reviewed:** 2026-09-20T08:20:37.817Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script invokes a global npm install for Claude Code, calls persistent PATH modification code, and creates a desktop launcher. - **Attack narrative:** The package's postinstall hook runs automatically. If Claude Code is missing, it invokes npm to install that separate AI-agent CLI globally. The hook then persists the global bin path in shell startup files and creates or replaces an application bundle in the user's Applications directory. These are unconsented install-time mutations beyond installing this package itself. - **Rationale:** The automatic lifecycle hook changes a foreign AI-agent control surface and persistent user environment. This is concrete install-hook abuse, not an explicit user-invoked setup action. - **Files touched:** npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs the postinstall bootstrap., The bootstrap installs the separate Claude Code package globally when the command is absent., The same automatic hook persists the global npm bin directory in shell startup files., The hook also creates and replaces a desktop application copy under the user's Applications directory. - **Evidence against:** The bundled wheel metadata lists ordinary Python application dependencies and no runtime dependency on this npm package. ## Affected versions and remediation This report applies to agent-takkub@1.0.82. - Avoid installing agent-takkub@1.0.82. 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.
