Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package invokes a bundled native executable automatically. It runs its authentication logout action, which clears local CLI login state without an explicit user request. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-11T09:20:17.930Z - **Finished:** 2026-09-11T09:21:06.030Z - **Download time:** 762 ms - **Static scan time:** 180 ms - **AI review time:** 47157 ms - **Total time:** 48100 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:** Installing the package invokes a bundled native executable automatically. It runs its authentication logout action, which clears local CLI login state without an explicit user request. - **Trigger:** npm installation triggers postinstall. - **Impact:** Loss of locally stored Tencent Meeting CLI authentication state and unconsented execution of a native binary. - **Evidence paths:** package.json, scripts/cleanup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T09:21:06.030Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install hook executes bundled native logout command. - **Attack narrative:** During installation, npm runs scripts/cleanup.js. The script selects a platform-specific bundled binary, grants it execute permission where applicable, and invokes \`auth logout\`. This automatic command can remove the user's existing local authentication state and executes opaque native code outside an explicit CLI action. - **Rationale:** The package contains an unconsented postinstall action that invokes a native logout operation and mutates user authentication state. This is concrete destructive install-hook behavior, not necessary package setup. - **Files touched:** scripts/cleanup.js, dist/tmeet-macOS-Intel, dist/tmeet-macOS-AppleSilicon, dist/tmeet-Linux-x86\_64, dist/tmeet-Linux-ARM64, dist/tmeet-Windows-x86\_64.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall hook automatically runs a cleanup script., The cleanup script changes the shipped binary's mode and runs its logout command on every install., That automatic native-binary invocation can clear the user's stored CLI authentication state without a user command. - **Evidence against:** The JavaScript launcher maps platforms to bundled binaries and forwards explicit CLI arguments., No JavaScript source code harvests environment variables or sends data to a remote endpoint. ## Affected versions and remediation This report applies to @tencentcloud/tmeet@1.0.18. - Avoid installing @tencentcloud/tmeet@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.
