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 shows no automatic malicious behavior, but its included build helper deletes npm and Yarn configuration files when run. This is a real destructive side effect without an explicit prompt, so warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 81.0% - **Started:** 2026-11-03T01:41:59.439Z - **Finished:** 2026-11-03T01:42:52.405Z - **Download time:** 761 ms - **Static scan time:** 4479 ms - **AI review time:** 47724 ms - **Total time:** 52966 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 manually invoked build helper deletes the user's npm and Yarn configuration files. - **Trigger:** A user runs build.sh. - **Impact:** Package-manager settings and any stored registry credentials in those files may be lost. - **Evidence paths:** build.sh - **Review source:** ai\_review - **Reviewed:** 2026-11-03T01:42:52.405Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script runs rm -f on ~/.npmrc and ~/.yarnrc before installing dependencies and building. - **Rationale:** The package shows no automatic malicious behavior, but its included build helper deletes npm and Yarn configuration files when run. This is a real destructive side effect without an explicit prompt, so warn rather than block. - **Files touched:** ~/.npmrc, ~/.yarnrc - **Network endpoints:** https://app.files.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 81.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** build.sh deletes ~/.npmrc and ~/.yarnrc before running the build; invoking it can remove the user's package-manager configuration., The manifest points to the SDK entry point and lists only build, test, lint, and watch scripts; it declares no install lifecycle script., SDK requests use the configurable Files.com base URL and the API key set by the caller. - **Evidence against:** The build helper is not invoked by the manifest's scripts, so its deletions do not occur during normal package installation or import., The CLI wrapper only forwards arguments to an explicitly supplied or found files-cli binary., The SDK's default service endpoint is app.files.com. ## Affected versions and remediation This report applies to files.com@1.2.752. - Review the evidence and your use of files.com@1.2.752 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.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 9. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** bin/files-cli-ai - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 81.0% - **Path:** build.sh - **Public source:** [View source]() build.sh deletes ~/.npmrc and ~/.yarnrc before running the build; invoking it can remove the user's package-manager configuration. Public source snippet (untrusted): ```text #!/usr/bin/env bash rm -f ~/.npmrc rm -f ~/.yarnrc npm install --min-release-age=14 && npm run build ``` ### 12. Medium: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 81.0% - **Path:** package.json - **Public source:** [View source]() The manifest points to the SDK entry point and lists only build, test, lint, and watch scripts; it declares no install lifecycle script.
