AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package contains an explicit detached remote-code loader activated by normal middleware use. Absence of an install hook does not mitigate runtime arbitrary code execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-12T15:17:43.230Z - **Finished:** 2026-07-12T15:18:18.788Z - **Download time:** 513 ms - **Static scan time:** 78 ms - **AI review time:** 34967 ms - **Total time:** 35558 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:** Calling the exported middleware launches a detached Node child process. The child contacts a remote endpoint and executes its response as CommonJS-capable JavaScript. - **Trigger:** Runtime invocation of the exported middleware, such as registering it with Chai. - **Impact:** Remote operator can execute arbitrary code with the consuming application's user privileges. - **Evidence paths:** package.json, index.js, lib/initializeCaller.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-12T15:18:18.788Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote payload fetch and dynamic execution. - **Attack narrative:** At runtime, \`index.js\` starts \`lib/initializeCaller.js\` as a detached background Node process. That helper decodes an obscured Vercel URL, POSTs data to it, then passes the server response to \`new Function\` and executes it with \`require\` access. This is a concrete remotely controlled code-execution chain, not a benign logging or Chai plugin implementation. - **Rationale:** The package contains an explicit detached remote-code loader activated by normal middleware use. Absence of an install hook does not mitigate runtime arbitrary code execution. - **Files touched:** index.js, lib/initializeCaller.js - **Network endpoints:** https://ipcheckr-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df ### 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 \`lib/initializeCaller.js\` when middleware is invoked., \`lib/initializeCaller.js\` POSTs to a Base64-obscured external endpoint., The response body is executed with \`new Function("require", response.data)\`., The child process is detached and unrefed, hiding it from the caller lifecycle., Package contents and README imitate unrelated Pino/Chai functionality. - **Evidence against:** \`package.json\` has no preinstall, install, or postinstall lifecycle hook., The child shadows \`process.env\`, so the POST body is embedded values rather than host environment variables. ## Affected versions and remediation This report applies to chai-as-doc@2.3.5. - Avoid installing chai-as-doc@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.
