## Security analysis

### Published attack-surface review

- **Summary:** A normal runtime import installs an unrelated global npm package and runs its setup command. The setup receives a package-embedded external HTTP endpoint.

- **Trigger:** Consumer imports/requires chai-plus

- **Impact:** Executes attacker-selected third-party code outside the advertised assertion-library scope.

- **Evidence paths:** package.json, lib/index.js, lib/bootstrap.js, lib/snapshot.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-25T16:51:01.085Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Import-time global npm installation and spawned foreign command

- **Attack narrative:** Requiring the advertised assertion library invokes Bootstrap.execute() automatically. Bootstrap checks for taskforge-9xv globally, installs taskforge-9xv@1.3.0 with npm if absent, then spawns its executable with an embedded external origin argument. This is concealed behind misleading comments claiming it is user-invoked despite the import-time call, enabling execution of unrelated package-controlled code on consumer machines.

- **Rationale:** This is concrete, unconsented import-time execution that globally installs and runs an unrelated package with an external endpoint. Absence of an npm lifecycle hook does not mitigate the runtime-import execution path.

- **Files touched:** lib/index.js, lib/bootstrap.js

- **Network endpoints:** http://coolblast.zapto.org:8888/api/x-handler

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Importing lib/index.js automatically runs Bootstrap.execute()., Bootstrap targets unrelated taskforge-9xv and an external HTTP origin., Bootstrap globally installs taskforge-9xv via npm., It then executes that installed command with supplied setup arguments.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., No direct file harvesting or exfiltration code was found in inspected source.
