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 is not malicious based on the reviewed entry points, but its shipped build helper deletes user-level npm and Yarn configuration without explaining or requesting that cleanup. Because the helper is not an install hook, this is a suspicious destructive side effect rather than install-time abuse. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-11-03T01:41:54.873Z - **Finished:** 2026-11-03T01:42:44.753Z - **Download time:** 769 ms - **Static scan time:** 4322 ms - **AI review time:** 44787 ms - **Total time:** 49880 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 two user-level package-manager configuration files. - **Trigger:** A user or build process explicitly runs build.sh. - **Impact:** Existing npm and Yarn configuration is lost. - **Evidence paths:** build.sh - **Review source:** ai\_review - **Reviewed:** 2026-11-03T01:42:44.753Z ### 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 is not malicious based on the reviewed entry points, but its shipped build helper deletes user-level npm and Yarn configuration without explaining or requesting that cleanup. Because the helper is not an install hook, this is a suspicious destructive side effect rather than install-time abuse. - **Files touched:** build.sh, ~/.npmrc, ~/.yarnrc - **Network endpoints:** https://app.files.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The shipped build.sh unconditionally removes ~/.npmrc and ~/.yarnrc when invoked, then installs build dependencies., The package exposes build.sh separately; its npm build script only runs Babel, so the destructive cleanup is not an install lifecycle action. - **Evidence against:** The manifest has no preinstall, install, or postinstall script., The SDK sends requests through its configured Files.com API base URL, consistent with its stated purpose., The AI CLI wrapper delegates to an existing files-cli binary and does not download or execute remote code. ## Affected versions and remediation This report applies to files.com@1.2.745. - Review the evidence and your use of files.com@1.2.745 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 5. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 6. Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** build.sh - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```shell path = build.sh kind = build_helper sizeBytes = 102 magicHex = [redacted] ``` ### 7. Medium: Oversized Source File - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** lib/models/AutomationLog.js - **Public source:** [View source]() Package contains source files above the normal full-analysis size ceiling. Public source snippet (untrusted): ```javascript path = lib/models/AutomationLog.js kind = oversized_source_file sizeBytes = 4629142 magicHex = [redacted] ``` ### 8. 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. Public source snippet (untrusted): ```text stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 1 ``` ### 10. Critical: Manifest Confusion - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Tarball package.json differs from the npm registry version manifest for scripts or dependency sets. Public source snippet (untrusted): ```json scripts changed=build ``` ### 11. Medium: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 88.0% - **Path:** build.sh - **Public source:** [View source]() The shipped build.sh unconditionally removes ~/.npmrc and ~/.yarnrc when invoked, then installs build dependencies. 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:** 88.0% - **Path:** package.json - **Public source:** [View source]() The package exposes build.sh separately; its npm build script only runs Babel, so the destructive cleanup is not an install lifecycle action. Public source snippet (untrusted): ```json "scripts": { "build": "./node_modules/.bin/babel src -d lib", "test": "jest", "lint": "eslint --fix src/", ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 4 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 16 - **Published dependency-graph edges:** 4 ### Published dependency entries - @babel/runtime ^7.10.3 (Dependency) - cross-fetch ^4.0.0 (Dependency) - readable-stream ^4.4.0 (Dependency) - safe-buffer ^5.2.1 (Dependency) ## Package metadata - **Package:** files.com - **Ecosystem:** npm - **Version:** 1.2.745 - **License:** MIT - **Version published:** 2026-09-19T18:09:12.974Z - **Package first seen:** 2026-07-01T08:21:16.434Z - **Package last seen:** 2026-11-03T14:40:22.120Z - **Known versions:** 97 - **Latest version:** 2.0.24 - **Appeal under review:** No - **Description:** Files.com SDK for JavaScript - **Author:** Files.com - **Maintainers:** files.com - **Keywords:** files.com, cloud storage, api - **Runtime engines:** node: ^6 || ^8.1 || \>=10.\* - **Artifact files:** 476 - **Artifact unpacked size:** 20,747,057 bytes - **Artifact signatures:** 2 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
