Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Remote endpoint operators can run arbitrary Node.js code with the consuming application's permissions. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 7.0.9 - **Selected version is latest:** Yes - **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 a concrete remote-code-execution chain, not merely suspicious primitives. The lack of install hooks limits the trigger to package use but does not reduce the impact of arbitrary runtime payload execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-14T07:13:50.613Z - **Finished:** 2026-07-14T07:14:59.715Z - **Download time:** 510 ms - **Static scan time:** 61 ms - **AI review time:** 68531 ms - **Total time:** 69102 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:** Invoking the package export launches a detached child process. That child fetches remote JavaScript and executes it locally, giving the endpoint arbitrary code execution in the consumer process environment. - **Trigger:** A consumer invokes the exported middleware function from \`index.js\`. - **Impact:** Remote endpoint operators can run arbitrary Node.js code with the consuming application's permissions. - **Evidence paths:** package.json, index.js, lib/initializeCaller.js, lib/const.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-14T07:14:59.715Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote payload fetch followed by dynamic code execution. - **Attack narrative:** At runtime, calling the exported middleware starts a detached Node process running \`lib/initializeCaller.js\`. It Base64-decodes a hard-coded endpoint, fetches JSON from it with a header, extracts \`data.cookie\`, compiles that response through \`Function.constructor\`, and invokes it with \`require\`. This is a remote, mutable payload channel that executes with the consumer's local Node permissions and hides normal child output. - **Rationale:** Source inspection confirms a concrete remote-code-execution chain, not merely suspicious primitives. The lack of install hooks limits the trigger to package use but does not reduce the impact of arbitrary runtime payload execution. - **Files touched:** index.js, lib/initializeCaller.js - **Network endpoints:** https://tomato-brunhilda-40.tiiny.site/index.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`index.js\` spawns detached Node child when exported middleware is invoked., \`lib/initializeCaller.js\` decodes an obscured remote URL and issues an Axios GET., The remote response field is compiled with \`Function.constructor\` and executed with \`require\`., The request retries silently up to five times; detached child uses ignored stdio., \`package.json\` has no lifecycle hooks, so activation is runtime rather than install-time. - **Evidence against:** No package lifecycle scripts (\`preinstall\`, \`install\`, or \`postinstall\`) are declared., No AI-agent configuration or persistence-control paths were found in inspected runtime source. ## Affected versions and remediation This report applies to chai-as-hardened@7.0.9. - Avoid installing chai-as-hardened@7.0.9. 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.
