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. The package's main SDK behavior appears consistent with its Files.com purpose, but build.sh has an unexplained destructive side effect that can erase user package-manager configuration. Since the script is only manually invoked and is not wired into install or the declared build script, this warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 85.0% - **Started:** 2026-11-03T01:33:38.139Z - **Finished:** 2026-11-03T01:34:23.665Z - **Download time:** 780 ms - **Static scan time:** 4161 ms - **AI review time:** 40583 ms - **Total time:** 45526 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:** A build helper deletes the user's npm and Yarn configuration files. - **Trigger:** Only when a user explicitly runs build.sh; it is not declared as an install hook or npm script. - **Impact:** Can erase package-manager settings and credentials stored in those files, disrupting package access and other workflows. - **Evidence paths:** build.sh - **Review source:** ai\_review - **Reviewed:** 2026-11-03T01:34:23.665Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Runs rm -f on ~/.npmrc and ~/.yarnrc, then invokes npm install and npm run build. - **Rationale:** The package's main SDK behavior appears consistent with its Files.com purpose, but build.sh has an unexplained destructive side effect that can erase user package-manager configuration. Since the script is only manually invoked and is not wired into install or the declared build script, this warrants a warning rather than a publish block. - **Files touched:** ~/.npmrc, ~/.yarnrc ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** build.sh silently deletes ~/.npmrc and ~/.yarnrc before running npm install and the build., The manifest has no install lifecycle hook, and build.sh is not among its declared npm scripts. - **Evidence against:** The package identifies itself as the Files.com JavaScript SDK and uses app.files.com as its default API host., The CLI shim only delegates to a configured or package-local files-cli executable. ## Affected versions and remediation This report applies to files.com@1.2.733. - Review the evidence and your use of files.com@1.2.733 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.
