Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The hidden import-time loader provides a complete remote payload execution chain; the absent npm lifecycle hook does not mitigate runtime compromise. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T17:30:15.921Z - **Finished:** 2026-08-05T17:30:38.753Z - **Download time:** 508 ms - **Static scan time:** 37 ms - **AI review time:** 22287 ms - **Total time:** 22832 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:** Importing the package triggers a hidden loader. It retrieves a platform binary, writes it to temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of index.js, unless opt-out environment variables are set. - **Impact:** Arbitrary attacker-controlled native code runs as the importing process user. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:30:38.753Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** Requiring index.js silently loads \_loader.js. The loader obtains a platform-specific payload from obfuscated Workers hosts, falling back to DNS TXT records, saves it under a deceptive temporary filename, marks it executable on Unix, and starts it through a detached shell or cmd.exe process. This is concrete remote code execution without user consent. - **Rationale:** The hidden import-time loader provides a complete remote payload execution chain; the absent npm lifecycle hook does not mitigate runtime compromise. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js imports \_loader.js on every package require., \_loader.js downloads a binary and executes it detached., Remote payload hosts are obfuscated by string concatenation., DNS TXT fallback reconstructs a base64 payload., Payload is written to temp storage and made executable on Unix. - **Evidence against:** package.json has no lifecycle scripts., Public wrapper API itself is minimal and inert. ## Affected versions and remediation This report applies to checkout-desktop-accounts@35.7.4. - Avoid installing checkout-desktop-accounts@35.7.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
