AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The source confirms a runtime path from normal package use to a detached helper that fetches and executes remote code; this is concrete malicious behavior even without install hooks. Scanner labels are corroborated by direct inspection of index.js and lib/initializeCaller.js. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-07-10T09:41:56.591Z - **Finished:** 2026-07-10T09:42:40.279Z - **Download time:** 510 ms - **Static scan time:** 67 ms - **AI review time:** 43110 ms - **Total time:** 43688 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:** Runtime use of the exported middleware launches a detached helper that fetches code from a remote endpoint and executes it. This is unconsented remote code execution in the consuming application's context. - **Trigger:** Calling the exported function from index.js, as shown by normal package usage. - **Impact:** Remote server can run arbitrary Node.js code with access to require and the consumer app's privileges. - **Evidence paths:** package.json, index.js, lib/initializeCaller.js, lib/const.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-10T09:42:40.279Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** detached child process plus remote JavaScript execution - **Attack narrative:** A consumer imports cookie-phase and calls the exported middleware/plugin. index.js starts a detached node process running lib/initializeCaller.js. That helper decodes a hidden URL, posts to it with axios, then treats the server response as JavaScript and runs it through new Function with require available, allowing arbitrary remote payload execution. - **Rationale:** The source confirms a runtime path from normal package use to a detached helper that fetches and executes remote code; this is concrete malicious behavior even without install hooks. Scanner labels are corroborated by direct inspection of index.js and lib/initializeCaller.js. - **Files touched:** lib/initializeCaller.js - **Network endpoints:** https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df, https://purple-kelila-79.tiiny.site/data.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js exports middleware that spawns detached node child process for lib/initializeCaller.js when called., lib/initializeCaller.js decodes an obscured HTTPS endpoint and POSTs to it with axios., lib/initializeCaller.js executes response.data via new Function("require", response.data)., README presents normal chai plugin usage that calls cookiePhase, activating the background task., lib/const.js contains another base64-obscured URL, though it is not imported by the observed entrypoint. - **Evidence against:** package.json has no install/preinstall/postinstall lifecycle scripts., The helper shadows process.env with hardcoded values rather than directly harvesting the real host environment., No filesystem writes, persistence, destructive code, or AI-agent control-surface mutation found in inspected source. ## Affected versions and remediation This report applies to cookie-phase@2.3.5. - Avoid installing cookie-phase@2.3.5. 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.
