LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.0.8 - **Selected version is latest:** No - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-10637 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-10637 confirms this npm version as malicious. mc-reg advertises itself as a Cosmos chain-registry data package (README shows chain-registry-style \`assets\`/\`chains\`/\`ibc\` API), but its main and ESM entrypoints do not expose that data. Instead, index.js lazy-imports and re-exports \`PartnerVaultHttpProvider\` from an unrelated runtime dependency \`chain-sdk-js\`, and esm/index.js statically imports it — so \`require('mc-reg')\` or \`import { chains } from 'mc-reg'\`... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-19T09:29:04.335Z - **Finished:** 2026-08-19T09:30:06.458Z - **Download time:** 509 ms - **Static scan time:** 45 ms - **AI review time:** 61568 ms - **Total time:** 62123 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:** The install lifecycle targets \`apps\`, whose index source is an external-file payload launcher. The source reads a parent-relative file and supplies its contents to a detached Node interpreter. - **Trigger:** npm postinstall, if the \`apps\` entry resolves and runs - **Impact:** Potential local code execution from a file outside the package boundary; execution is not confirmed due to the manifest/module mismatch. - **Evidence paths:** package.json, apps/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-19T09:30:06.458Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** external-file content piped into detached Node - **Rationale:** The package contains a concrete install-time staged-payload launcher, but source facts do not establish that its malformed/ambiguous entrypoint executes successfully. Warn rather than block. - **Files touched:** apps/index.js, ../../../public/logo.svg ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for AI warning decision:** Install hook invokes Node on \`apps\`., \`apps/index.js\` reads \`../../../public/logo.svg\`, outside the package root., It pipes that file's contents to a detached Node process and unreferences it. - **Evidence against:** No network or credential-exfiltration code was found., The root manifest does not declare ESM mode although the lifecycle source uses ESM imports, so successful execution is not confirmed by source alone. ## Affected versions and remediation This report applies to mc-reg@1.0.8. - Avoid installing mc-reg@1.0.8. 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.
