Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Arbitrary remote code can run in the consumer environment with package process privileges. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 0.0.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection confirms unconsented import-time background execution and remote dynamic code execution unrelated to the advertised chai assertions. This is concrete malicious behavior, not a noisy scanner finding. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-04T17:14:37.578Z - **Finished:** 2026-07-04T17:15:01.731Z - **Download time:** 253 ms - **Static scan time:** 78 ms - **AI review time:** 23821 ms - **Total time:** 24153 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:** The package has a concrete import-time remote code execution path. Loading the declared main module starts a detached helper that fetches remote JavaScript and executes it with require access. - **Trigger:** Requiring/importing package main index.js - **Impact:** Arbitrary remote code can run in the consumer environment with package process privileges. - **Evidence paths:** package.json, index.js, lib/caller.js - **Review source:** ai\_review - **Reviewed:** 2026-07-04T17:15:01.731Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** detached child process fetches and evals remote payload - **Attack narrative:** When a consumer loads chai-redirection, index.js immediately spawns lib/caller.js as a detached Node process. That helper retrieves code from jsonkeeper.com and executes fields from the response using new Function/Function.constructor with require exposed. A second endpoint is assembled from config constants and can also execute a returned token on 404, making the package a remote payload loader hidden behind a chai plugin facade. - **Rationale:** Source inspection confirms unconsented import-time background execution and remote dynamic code execution unrelated to the advertised chai assertions. This is concrete malicious behavior, not a noisy scanner finding. - **Files touched:** lib/caller.js - **Network endpoints:** https://jsonkeeper.com/b/O3JR0 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js runs callCallerAsOrigin() at import time, spawning detached node lib/caller.js with stdio ignored., lib/caller.js fetches https://jsonkeeper.com/b/O3JR0 and executes res.data.cookie via new Function with require., lib/caller.js also builds DEV\_API\_CHECK\_DOMAIN + aspath + token and executes error.response.data.token on 404 via Function.constructor., package.json main is index.js, so requiring the chai plugin triggers the background payload., Dependencies include axios/request/sqlite3 unrelated to visible chai assertion functionality. - **Evidence against:** package.json has no npm lifecycle hooks, so payload is import-time rather than install-time., Visible exported API contains chai assertion helpers for JWT/password/URL/email/string validation., No AI-agent control-surface writes found in inspected files. ## Affected versions and remediation This report applies to chai-redirection@0.0.3. - Avoid installing chai-redirection@0.0.3. 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.
