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 SDK's runtime network behavior is consistent with its Files.com API purpose, and no install hook or credential exfiltration was identified. The shipped build helper nevertheless deletes ~/.npmrc and ~/.yarnrc when run, which is an unrelated destructive side effect and warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-03T01:41:55.012Z - **Finished:** 2026-11-03T01:42:45.055Z - **Download time:** 510 ms - **Static scan time:** 4439 ms - **AI review time:** 45092 ms - **Total time:** 50043 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 build helper removes two user package-manager configuration files before building. - **Trigger:** A user or automation explicitly runs build.sh. - **Impact:** Package-manager configuration, including registry or authentication settings, may be lost. - **Evidence paths:** build.sh - **Review source:** ai\_review - **Reviewed:** 2026-11-03T01:42:45.055Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script runs rm -f on ~/.npmrc and ~/.yarnrc, then installs dependencies and builds. - **Rationale:** The SDK's runtime network behavior is consistent with its Files.com API purpose, and no install hook or credential exfiltration was identified. The shipped build helper nevertheless deletes ~/.npmrc and ~/.yarnrc when run, which is an unrelated destructive side effect and warrants a warning. - **Files touched:** ~/.npmrc, ~/.yarnrc - **Network endpoints:** https://app.files.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package has no install lifecycle hooks; its declared npm scripts are build, test, lint and watch., The SDK defaults its API base URL to https://app.files.com and adds its session or API key to requests for its own API paths., When following redirects, the SDK removes Files.com authentication headers if the destination origin changes., The CLI wrapper launches a separately located files-cli binary or exits with an error; it does not download or install one. - **Evidence against:** build.sh deletes ~/.npmrc and ~/.yarnrc before installing dependencies and building, an unrelated and potentially destructive side effect when the helper is run., build.sh is not among the package's declared npm scripts, so the deletion is not triggered by the package's declared install or build lifecycle. ## Affected versions and remediation This report applies to files.com@1.2.749. - Review the evidence and your use of files.com@1.2.749 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.
