Explicit hook setup persists global AI-agent hooks that capture context and invoke the latest package release before uploading collected data. - **Trigger:** npm installation triggers the binary download; explicit Claude or Windsurf hook setup triggers persistent processing on later agent events. - **Impact:** Agent transcripts, prompts, inferences, workspace context, and bundled credentials can be exposed; later package releases execute through the persistent hook. - **Evidence paths:** .env, package.json, src/post\_install/cx\_install.mjs, dist/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T16:53:13.897Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent AI-agent hooks launch latest-package code and upload collected context. - **Attack narrative:** The package runs a postinstall downloader that places a remote executable in the consumer project. Its explicit hook commands modify global Claude and Windsurf configuration, creating persistent hooks. The Claude hook launches a detached npx mobbdev@latest daemon, so future releases can run automatically. That daemon scans Claude-related context and uploads files, prompts, and inferences to remote upload URLs. The package also ships a production-style environment file containing credential assignments. - **Rationale:** The package implements concrete persistent agent-data collection and upload behavior, plus a latest-version self-install path and an automatic external binary download. The explicit hook-install command reduces accidental activation but does not remove the demonstrated exfiltration and persistence chain. - **Files touched:** .env, node\_modules/.bin/cx, ~/.claude/settings.json, ~/.mobbdev/daemon-check.js, ~/.codeium/hooks.json - **Network endpoints:** github.com, api.mobb.ai ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The published .env contains production-style credential assignments., The automatic postinstall downloads and extracts an external executable into node\_modules/.bin without an integrity check., An installed Claude hook starts a detached npx process for mobbdev@latest, allowing later releases to run automatically., Hook processing collects Claude workspace context, prompts, and inferences, then uploads them to server-provided URLs. - **Evidence against:** Claude hook installation is initiated by an explicit CLI command and performs authentication first., The postinstall download is fixed to a Checkmarx release URL and is limited to a named binary. ## Public findings ### 1.
