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. An automatic install hook transmits host uptime information to an external endpoint. Shell-variable assembly obscures the curl command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-05T16:45:05.524Z - **Finished:** 2026-10-05T16:45:46.050Z - **Download time:** 1266 ms - **Static scan time:** 7 ms - **AI review time:** 39252 ms - **Total time:** 40526 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:** An automatic install hook transmits host uptime information to an external endpoint. Shell-variable assembly obscures the curl command. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** Exposes host uptime, user-count and load information and signals installation to the recipient. - **Evidence paths:** package.json, test.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-05T16:45:46.050Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The preinstall hook executes test.sh, which runs uptime and passes its output to curl as POST data. - **Attack narrative:** Installation invokes test.sh automatically. The script assembles curl from variables, executes uptime, and posts the resulting host information to an external endpoint. There is no consent gate. Claims about collecting nothing and evading scanner visibility do not neutralize this active behavior. - **Rationale:** Source confirms automatic, obscured transmission of host information unrelated to the stylesheet functionality. This supports blocking for malicious install-hook abuse, without claiming that the commented environment-harvesting command executes. - **Network endpoints:** https://abbishal.com/sh/poc ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json automatically runs test.sh through preinstall., test.sh constructs curl from shell variables and posts uptime output to https://abbishal.com/sh/poc without an opt-in gate., test.sh claims to collect nothing and be invisible to malware scanners, contradicting its active transmission and attempting to excuse the behavior. - **Evidence against:** colours.scss contains stylesheet variables and mixins., The active payload sends uptime information; the environment-harvesting command is commented out. ## Affected versions and remediation This report applies to abbishal-poc2@1.2.0. - Avoid installing abbishal-poc2@1.2.0. 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.
