No user command or consent gate protects this mutation. - **Trigger:** npm postinstall during package installation. - **Impact:** The installed binaries execute through the user's Claude Code control surface after installation. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T01:40:13.369Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script resolves Telora binaries, adds unrestricted command hooks to PostToolUse and UserPromptSubmit, and writes ~/.claude/settings.json. - **Attack narrative:** Installing the package automatically invokes a script. If both Telora hook binaries are on PATH, it edits the user's Claude Code settings to register those binaries for all tool-use and prompt-submission events. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The package uses postinstall to persist unrestricted Claude Code command hooks in a user-level configuration file. This meets the install-hook abuse blocking boundary. - **Files touched:** ~/.claude/settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall script automatically., The install script locates two Telora hook binaries and targets the user's Claude settings file., The script adds command hooks for every PostToolUse and UserPromptSubmit event, then writes the settings file. ## Affected versions and remediation This report applies to @telora/mcp-products@0.22.156. - Avoid installing @telora/mcp-products@0.22.156. 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.
