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. The package is a Mobb remediation CLI whose agent hooks are first-party and command-gated, but those commands persist broad Claude and Codeium hooks that respawn mobbdev@latest and upload session context. Postinstall also pulls a remote Checkmarx binary, so the combined capability is a warning rather than a silent install-time hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 76.0% - **Started:** 2026-09-24T00:42:35.218Z - **Finished:** 2026-09-24T00:44:41.794Z - **Download time:** 254 ms - **Static scan time:** 3022 ms - **AI review time:** 123298 ms - **Total time:** 126576 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:** Install does not rewrite agent configs. Explicit hook commands persist Mobb commands in Claude and Codeium settings, and the Claude daemon can later widen its matcher and upload session context to Mobb. Postinstall also fetches a third-party Checkmarx scanner binary into node\_modules/.bin. - **Trigger:** npm postinstall for the Checkmarx binary; user commands claude-code-install-hook and windsurf-intellij-install-hook, then later Claude PostToolUse or the daemon. - **Impact:** A consented hook keeps a background Mobb collector on the machine and sends Claude session material to the vendor. The install-time download executes only the extracted Checkmarx scanner binary in the package bin directory. - **Evidence paths:** package.json, src/post\_install/cx\_install.mjs, src/post\_install/binary.mjs, dist/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-24T00:44:41.794Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hook installers write home-directory agent settings that launch npx mobbdev@latest. The daemon refreshes ~/.claude/settings.json and uploads transcripts and context after Mobb authentication. Postinstall streams a pinned GitHub archive and extracts cx into node\_modules/.bin. - **Rationale:** The package is a Mobb remediation CLI whose agent hooks are first-party and command-gated, but those commands persist broad Claude and Codeium hooks that respawn mobbdev@latest and upload session context. Postinstall also pulls a remote Checkmarx binary, so the combined capability is a warning rather than a silent install-time hijack. - **Files touched:** node\_modules/.bin, ~/.claude/settings.json, ~/.mobbdev, ~/.codeium/hooks.json - **Network endpoints:** https://github.com/Checkmarx/ast-cli/releases/download/2.0.55/, https://api.mobb.ai/v1/graphql ### Review decision - **Verdict:** Suspicious - **Confidence:** 76.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** postinstall runs src/post\_install/cx\_install.mjs, which downloads a pinned Checkmarx ast-cli archive and extracts the scanner binary into node\_modules/.bin., The claude-code-install-hook command writes a PostToolUse command hook into the user home Claude settings file., That hook and the daemon shim spawn npx --yes mobbdev@latest claude-code-daemon, and the daemon widens an existing Mobb matcher to \* then rewrites the settings file., The windsurf-intellij-install-hook command writes ~/.codeium/hooks.json so post\_write\_code runs npx --yes mobbdev@latest windsurf-intellij-process-hook., After authentication the Claude daemon uploads session transcripts, context files, and skills to the Mobb upload pipeline. - **Evidence against:** Hook installation is a named CLI command that first authenticates to the Mobb GraphQL API; npm postinstall does not write Claude or Codeium config., The Checkmarx download uses a fixed GitHub release URL, installs only the cx binary, and skips the download when that binary already exists., API\_URL in .env points at https://api.mobb.ai/v1/graphql, matching the package vendor, and the bundled SCM tokens are empty. ## Affected versions and remediation This report applies to mobbdev@1.5.4. - Review the evidence and your use of mobbdev@1.5.4 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.
