## Verdict summary
**Blocked & quarantined** — Arbitrary attacker-controlled native code executes as the importing process user.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 35.7.5
- **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.

This is an import-time, covert remote-code-execution chain unrelated to the declared log formatter functionality. Lack of an npm lifecycle hook does not mitigate execution on normal package use.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Malicious
- **Recorded analysis confidence:** 99.0%
- **Started:** 2026-08-05T17:25:37.445Z

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 silently triggers a remote payload retrieval and execution chain. It drops a platform-specific binary in a temp directory and launches it detached.

- **Trigger:** Any runtime require/import of checkout-dolyame-logic

- **Impact:** Arbitrary attacker-controlled native code executes as the importing process user.

- **Evidence paths:** package.json, index.js, \_runtime.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:25:59.380Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** remote binary download, temporary-file drop, and detached execution

- **Attack narrative:** The public entrypoint loads \_runtime.js inside a swallowed try/catch. That module immediately invokes setup(), fetches a platform payload from obfuscated HTTPS mirrors or DNS TXT records, writes it under a temporary path, chmods it on Unix, and launches it via shell/cmd in detached mode.

- **Rationale:** This is an import-time, covert remote-code-execution chain unrelated to the declared log formatter functionality. Lack of an npm lifecycle hook does not mitigate execution on normal package use.

- **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>

- **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.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 \_runtime.js on every package import., \_runtime.js downloads platform binaries from obfuscated Workers hosts and DNS TXT records., \_runtime.js writes the payload to a temp directory, marks it executable, then detached-spawns it., The marker file only throttles repeated execution; it does not require user consent.

- **Evidence against:** package.json has no lifecycle scripts., The advertised Logger export itself is a simple formatter.

## Affected versions and remediation

This report applies to checkout-dolyame-logic@35.7.5.

- Avoid installing checkout-dolyame-logic@35.7.5. 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.
