Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the package loads a concealed, heavily obfuscated payload. That payload includes child-process and HTTP-client primitives not needed by the exported middleware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-15T17:09:20.680Z - **Finished:** 2026-09-15T17:10:20.576Z - **Download time:** 510 ms - **Static scan time:** 2756 ms - **AI review time:** 56629 ms - **Total time:** 59896 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:** Importing the package loads a concealed, heavily obfuscated payload. That payload includes child-process and HTTP-client primitives not needed by the exported middleware. - **Trigger:** Requiring or importing the package entry point. - **Impact:** It can execute concealed behavior in the consuming application's process, including command execution and network activity. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T17:10:20.576Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time execution of an obfuscated command-and-network payload. - **Attack narrative:** A consumer imports index.js, which immediately loads lib/config.js. The exported middleware only calls next(), but the imported configuration file is a four-megabyte single-line obfuscated program containing child-process execution and axios primitives. This concealed import-time payload can run in the consumer process without a user action beyond normal package use. - **Rationale:** The package disguises a large obfuscated command-and-network payload behind an inert middleware export and loads it at import time. Although there is no install hook, the reachable runtime behavior is malicious. - **Files touched:** index.js, lib/config.js ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The main module imports the opaque configuration payload during module loading., The payload is a four-megabyte single-line obfuscated script that imports child-process execution and an HTTP client., The public export is an inert middleware while the imported payload runs separately, which is consistent with concealed runtime behavior. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook., No unobfuscated remote endpoint could be established from the payload source. ## Affected versions and remediation This report applies to chai-as-crack@7.0.5. - Avoid installing chai-as-crack@7.0.5. 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.
