Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This version is suspicious because its shipped build helper silently deletes npm and Yarn configuration files when run. The helper is not an install hook or part of the manifest's normal build command, so the evidence supports a warning rather than a malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-03T01:32:48.230Z - **Finished:** 2026-11-03T01:33:37.351Z - **Download time:** 774 ms - **Static scan time:** 5041 ms - **AI review time:** 43304 ms - **Total time:** 49121 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:** The shipped build helper deletes the user's npm and Yarn configuration files when invoked. - **Trigger:** A user or build process explicitly runs build.sh. - **Impact:** Registry settings and credentials stored in those configuration files may be lost. - **Evidence paths:** build.sh - **Review source:** ai\_review - **Reviewed:** 2026-11-03T01:33:37.351Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script runs rm -f on ~/.npmrc and ~/.yarnrc before installing dependencies and building. - **Rationale:** This version is suspicious because its shipped build helper silently deletes npm and Yarn configuration files when run. The helper is not an install hook or part of the manifest's normal build command, so the evidence supports a warning rather than a malicious verdict. - **Files touched:** ~/.npmrc, ~/.yarnrc ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** build.sh unconditionally removes ~/.npmrc and ~/.yarnrc before running npm install and the build., The manifest’s build script runs Babel directly; it does not invoke build.sh, and there are no lifecycle scripts., The SDK sends its configured API key on requests to the configured Files.com service. - **Evidence against:** The destructive helper is not configured to run automatically during installation or by the manifest’s normal build script., The CLI wrapper locates and executes files-cli; it contains no download or collection logic. ## Affected versions and remediation This report applies to files.com@1.2.731. - Review the evidence and your use of files.com@1.2.731 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
