OpenSSF/OSV malware advisory MAL-2026-6482 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as clean; the assessments disagree.

Independent AI assessment: clean. LPM AI assessed this version as clean; the assessments disagree.

OpenSSF/OSV advisory MAL-2026-6482 confirms this npm version as malicious. On npm install, scripts/install-check.cjs runs as a postinstall hook and performs a two-stage remote-code-execution flow: it fetches a JSON config from https://www.zscdao.help/config/stake-math-sync.json, extracts a \`peerBundle\`/\`bundle\`/\`bundleUrl\`/\`url\` field, downloads the referenced.tgz to a temp directory, extracts it, runs \`npm install\` inside the extracted tree, then \`require()\`s the resulting module and...

## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface is present in shipped source. The only lifecycle hook points to a missing file, causing install failure rather than executing packaged payload code.

- **Trigger:** npm install attempts package.json postinstall

- **Impact:** install may fail; no observed credential, file, network, persistence, or destructive behavior

- **Evidence paths:** package.json, dist/index.js, dist/index.d.ts, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T06:50:09.955Z

### AI review details

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

- **Mechanism:** missing postinstall script target; runtime library is pure math

- **Rationale:** Static inspection found a suspicious lifecycle declaration and misleading README claim, but the referenced script is absent and the shipped entrypoint contains only package-aligned math code. No exfiltration, dynamic execution, persistence, destructive action, or AI-agent control-surface mutation was found.

- **Files touched:** scripts/install-check.cjs

- **Network endpoints:** https://www.zscdao.help/config/stake-math-sync.json, https://github.com/zscdao/kelly.git

### Review decision

- **Verdict:** Clean

- **Confidence:** 86.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Medium

- **Evidence for AI clean decision:** package.json defines postinstall: node scripts/install-check.cjs, scripts/install-check.cjs is not present in packaged files, so install would attempt a missing local script, package.json homepage points to https://www.zscdao.help/config/stake-math-sync.json but no code references it

- **Evidence against:** dist/index.js exports only deterministic Kelly math functions, No require/import, child\_process, eval/Function, fs access, env reads, or network calls in dist/index.js, Package contains only package.json, README, LICENSE, and dist artifacts, No bin entrypoint or import-time side effects beyond function definitions
