Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Arbitrary install-time code execution with potential dropped/executed payload and host/system telemetry disclosure - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Install Hook Abuse - **Selected version:** 5.5.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package has concrete unconsented install-time execution with obfuscation, process spawning, filesystem mutation, and telemetry behavior that exceeds the declared ESLint-config purpose. This supports blocking as malicious install-hook abuse rather than a noisy scanner false positive. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-07-04T23:47:10.159Z - **Finished:** 2026-07-04T23:47:52.301Z - **Download time:** 506 ms - **Static scan time:** 97 ms - **AI review time:** 41538 ms - **Total time:** 42142 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:** Install-time obfuscated code executes automatically and performs filesystem/process/network behavior inconsistent with an ESLint config package. The shipped runtime entry is also broken because it requires a missing src/index.js. - **Trigger:** npm install postinstall - **Impact:** Arbitrary install-time code execution with potential dropped/executed payload and host/system telemetry disclosure - **Evidence paths:** package.json, scripts/postinstall.js, dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-04T23:47:52.301Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** obfuscated install script with child process, filesystem mutation, detached execution, and telemetry - **Attack narrative:** On install, npm runs scripts/postinstall.js. That file is a large obfuscated one-line program that hides strings and includes decoded require calls, child-process execution, recursive filesystem handling, chmod, detached spawn, and network telemetry submission with system details. This is not package-aligned for an ESLint config, and the declared main points to a missing source file via dist/index.js, indicating the useful package surface is secondary to the installer. - **Rationale:** The package has concrete unconsented install-time execution with obfuscation, process spawning, filesystem mutation, and telemetry behavior that exceeds the declared ESLint-config purpose. This supports blocking as malicious install-hook abuse rather than a noisy scanner false positive. - **Files touched:** scripts/postinstall.js, dist/index.js, package.json, README.md - **Network endpoints:** telemetry.tqm-mfe.io, https://docs.tqm-mfe.io/platform/main, https://jira.tqm-mfe.io/projects/PLATFORM, https://npm.tqm-mfe.io, git+https://github.tqm-mfe.io/platform/main.git ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs postinstall: node scripts/postinstall.js, scripts/postinstall.js is a 182KB single-line heavily obfuscated installer, postinstall references require, atob, child process execution, recursive filesystem operations, chmod, and detached spawn patterns, postinstall collects package/version/timestamp and system fields before sending an install event, README claims install telemetry, but code behavior is far broader and obfuscated - **Evidence against:** dist/index.js only re-exports ../src/index.js, but src/index.js is absent from package, No AI-agent control-surface paths found in readable strings, No dependency payloads declared in package.json ## Affected versions and remediation This report applies to @tqm-mfe/main@5.5.0. - Avoid installing @tqm-mfe/main@5.5.0. 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.
