It passes a remote origin server to that program. - **Trigger:** A consumer imports or requires chai-plus. - **Impact:** An ordinary dependency import can execute external code and modify the user's global npm environment. - **Evidence paths:** package.json, lib/index.js, lib/bootstrap.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T14:08:12.657Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time global package installation followed by remote-service configuration. - **Attack narrative:** The declared main module executes an immediately invoked bootstrap function during import. If taskforge-9xv is absent globally, it installs that unrelated package and executes its command with configuration for a remote server. This is unrelated to an assertion library and occurs without an explicit user setup action, enabling unconsented host mutation and execution of a remotely sourced package. - **Rationale:** Source inspection confirms a concrete import-time global install and remote configuration chain unrelated to the advertised testing library. This is malicious dependency behavior. - **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 the package synchronously checks for and globally installs taskforge-9xv without user consent., The import-time code then runs taskforge setup with a remote origin server., The package has no lifecycle hook, so the harmful behavior starts when its normal main module is required. - **Evidence against:** No credential harvesting or local file exfiltration was found in the inspected source., The manifest declares no install lifecycle scripts. ## Public findings ### 1.
