LPM AI review remains unresolved. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.6.1 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-18322 identifies this version as malicious and supplies the Firewall block. LPM AI review remains unresolved. Independent AI assessment: manual\_review. LPM AI review remains unresolved. OpenSSF/OSV advisory MAL-2026-18322 confirms this npm version as malicious. Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 79.0% - **Started:** 2026-10-26T04:49:10.163Z - **Finished:** 2026-10-26T04:50:03.380Z - **Download time:** 2054 ms - **Static scan time:** 4367 ms - **AI review time:** 46795 ms - **Total time:** 53217 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:** No attack was confirmed. The active CLI loads heavily obfuscated runtime code whose behavior remains unresolved. - **Trigger:** Running the numbors CLI loads dist/main. - **Impact:** The effects of the unresolved operations cannot be determined from the inspected source. - **Evidence paths:** dist/main.js, dist/mcp-tools.js, dist/commands/forecast.js - **Review source:** ai\_review - **Reviewed:** 2026-10-26T04:50:03.380Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Encoded string tables and computed property lookups obscure runtime operations during static inspection. - **Rationale:** The CLI entrypoint reaches an obfuscated runtime, and inspection did not resolve its behavior. No concrete attack was established, so the package requires manual review. - **Files touched:** package.json, bin/cli.js, dist/main.js, dist/mcp-tools.js, dist/commands/forecast.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 79.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json exposes bin/cli.js, which loads dist/main; the runtime bundles contain encoded string tables and computed property lookups., The inspected source does not resolve the behavior behind those obfuscated runtime operations, so no attack is confirmed and safety remains undetermined. ## Affected versions and remediation This report applies to numbors@1.6.1. - Avoid installing numbors@1.6.1. 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.
