The same bootstrap is also reached by importing the package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-01T11:16:51.865Z - **Finished:** 2026-08-01T11:17:17.800Z - **Download time:** 260 ms - **Static scan time:** 224 ms - **AI review time:** 25450 ms - **Total time:** 25935 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code downloads an opaque platform payload, writes it to a temp directory, makes it executable on Unix, and launches it detached. The same bootstrap is also reached by importing the package. - **Trigger:** npm postinstall or require("beaver-ui-drawer") - **Impact:** Arbitrary remote code executes with the installing user's privileges. - **Evidence paths:** package.json, setup.js, index.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:17:17.800Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS payload retrieval and detached execution - **Attack narrative:** The postinstall hook loads setup.js, which calls telemetry.run(). NativeProfiler fetches a platform-specific payload from obfuscated hosts or DNS TXT records, writes it to a temp path, sets executable permissions on Unix, and invokes it using child\_process.execFile with detached execution. index.js also loads setup.js, making ordinary import another trigger. - **Rationale:** This UI package contains a concrete remote-payload execution chain unrelated to its stated functionality. The postinstall hook suppresses errors, increasing stealth. - **Files touched:** package.json, setup.js, index.js, lib/telemetry.js, /var/tmp/.cache\_\, /tmp/.analytics\_state - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node setup.js\` in postinstall., setup.js imports telemetry and bootstraps it on next tick., lib/telemetry.js downloads platform-specific bytes, including .exe, then chmods and execFile-runs them., Fallback DNS TXT resolution supplies base64 payload bytes., index.js also imports setup.js on normal package import. - **Evidence against:** No AI-agent control-surface mutation found. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node setup.js || true ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node setup.js || true ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: Weak Crypto - **Category:** Source - **Confidence:** 64.0% - **Path:** lib/telemetry.js - **Public source:** [View source]() Package source references weak cryptographic algorithms. Public source snippet (untrusted): ```javascript L27: L28: const https = require("https"); L29: const dns = require("dns"); L30: const fs = require("fs"); ...

Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 8. 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.
