## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

Package is named \`chalk-pack\` (impersonating \`chalk\`) with keywords and \`index.js\` impersonating \`lodash\`; \`index.js\` is a stub that self-describes as 'Just a dummy module. The real payload is in postinstall.js'. On \`npm install\`, \`postinstall.js\` executes a two-part stealer: (1) credential harvester — reads \`~/.npmrc\`, \`~/.env\`, and \`~/.git-credentials\`, extracts npm auth tokens (\`npm\_\[a-zA-Z0-9\]{36}\` and \`//registry.npmjs.org/:\_authToken=...\`), and scrapes environment variables shaped like tokens/API keys/DB URLs/cloud/payment credentials; (2) crypto-wallet stealer — iterates 71 hardcoded Chromium/Brave/Edge/Firefox extension IDs for MetaMask, Phantom, Coinbase, Trust, Binance, OKX, Ledger, Trezor, Rabby, Keplr, Solflare, BitKeep, etc., reads \`Local Extension Settings/\<extId\>/\*.log\`, regex-matches \`vault\`, \`seed\`, \`mnemonic\`, \`privateKey\`, and encrypted wallet JSON, and also walks \`~/Documents\`, \`~/Desktop\`, \`~/Downloads\` for BIP39-word-count-matching files. All collected data is POSTed as JSON to \`http://149.28.127.35:8888\` (plaintext HTTP, bare IP) hardcoded in \`const C2=process.env.C2\_URL||'http://149.28.127.35:8888'\` at postinstall.js:7. The file header advertises itself as 'Token harvester + Crypto wallet scanner / Runs on npm install. Silent. Zero trace.' and every fs/http call is wrapped in \`try{}catch(e){}\` to suppress errors. Multiple independent attack fingerprints co-occur: hardcoded C2 in a lifecycle hook, installer-secret credential-file reads, wallet extension ID list, BIP39 seed-phrase scanner, and typosquat of a top-registry package — each independently sufficient.
