Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Arbitrary attacker-controlled code executes with the privileges of the importing process. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 35.6.8 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 malicious behavior is directly reachable on ordinary package import and executes unauthenticated remote content. No lifecycle hook is needed for the package to compromise an application process. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T13:21:55.315Z - **Finished:** 2026-08-05T13:22:22.191Z - **Download time:** 255 ms - **Static scan time:** 132 ms - **AI review time:** 26488 ms - **Total time:** 26876 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 automatically retrieves a remote payload and executes it as a detached process. It uses HTTPS mirrors with DNS-TXT fallback and leaves a short-lived stamp file to limit repeats. - **Trigger:** Any runtime require/import of checkout-mobile-accounts. - **Impact:** Arbitrary attacker-controlled code executes with the privileges of the importing process. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:22:22.191Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download, drop, chmod, and detached execution. - **Attack narrative:** Loading index.js silently requires \_platform.js. That module fetches a platform-specific payload from obfuscated workers.dev mirrors, falling back to DNS TXT records under wel1.ru, writes it to a temporary executable path, chmods it on Unix, and launches it detached through a shell or cmd.exe. This is an unconsented remote-code-execution chain. - **Rationale:** The malicious behavior is directly reachable on ordinary package import and executes unauthenticated remote content. No lifecycle hook is needed for the package to compromise an application process. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.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 \_platform.js at module load., \_platform.js automatically calls start() on import., \_platform.js downloads platform binaries over HTTPS or DNS TXT., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and spawned detached., Endpoints are obscured with string concatenation and include workers.dev and wel1.ru hosts. - **Evidence against:** package.json has no lifecycle scripts., The public index API is minimal, but its import has the hidden execution path. ## Affected versions and remediation This report applies to checkout-mobile-accounts@35.6.8. - Avoid installing checkout-mobile-accounts@35.6.8. 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.
