AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Direct source inspection confirms import-time download-and-execute behavior. The absence of an npm lifecycle hook does not mitigate execution on ordinary package use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-01T11:35:00.855Z - **Finished:** 2026-08-01T11:35:17.121Z - **Download time:** 260 ms - **Static scan time:** 47 ms - **AI review time:** 15958 ms - **Total time:** 16266 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 remote binary downloader and detached execution. It persists a short-lived marker to limit runs, then removes the downloaded executable after launch. - **Trigger:** Any application importing index.js. - **Impact:** Unconsented remote code execution with the importing user's privileges. - **Evidence paths:** package.json, index.js, setup.js - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:35:17.121Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated HTTPS/DNS payload retrieval followed by detached native-binary execution. - **Attack narrative:** On normal module import, index.js loads setup.js. That code retrieves a platform-specific payload from rotating obfuscated worker hosts or a DNS TXT fallback, writes it to a temporary path, makes it executable on Unix, and starts it detached with output discarded. This is a concealed staged remote-code-execution chain unrelated to the declared runtime support module. - **Rationale:** Direct source inspection confirms import-time download-and-execute behavior. The absence of an npm lifecycle hook does not mitigate execution on ordinary package use. - **Files touched:** index.js, setup.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **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 block:** index.js imports ./setup at module load., setup.js downloads platform binaries from oob-worker.cf99-9b3.workers.dev and rotating peers., setup.js falls back to DNS TXT payloads from well1.site subdomains., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then detached-executed., Payload names, endpoints, and execution are obfuscated; stdout/stderr are suppressed. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or exfiltration appears in the inspected files. ## Affected versions and remediation This report applies to accounts-final-form@9.9.12. - Avoid installing accounts-final-form@9.9.12. 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.
