Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Installation triggers a shell command that lists cron-named files under \`/tmp\` and writes the result to another temporary file. No confirmed exfiltration, execution, or persistence follows. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-23T04:39:40.039Z - **Finished:** 2026-09-23T04:40:08.444Z - **Download time:** 514 ms - **Static scan time:** 27 ms - **AI review time:** 27864 ms - **Total time:** 28405 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:** Installation triggers a shell command that lists cron-named files under \`/tmp\` and writes the result to another temporary file. No confirmed exfiltration, execution, or persistence follows. - **Trigger:** npm install - **Impact:** Creates or appends \`/tmp/test.txt\` and may disclose local filenames to later local processes. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-23T04:40:08.444Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall filesystem enumeration and temporary-file write - **Rationale:** The install-time command is unnecessary and suspicious, but source inspection shows no concrete malicious chain beyond local temporary-file enumeration and logging. A warning is proportionate. - **Files touched:** /tmp/cron\*, /tmp/test.txt ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for block:** \`postinstall\` executes automatically during npm installation., It enumerates \`/tmp/cron\*\` and appends the listing to \`/tmp/test.txt\`. - **Evidence against:** No network endpoint, payload execution, credential access, or destructive action is present in the only package file., The declared \`index.js\` entrypoint is absent from the package. ## Affected versions and remediation This report applies to randompkga@1.0.18. - Avoid installing randompkga@1.0.18. 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.
