High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% cheerio-tool typosquats the popular \`cheerio\` HTML parser (README claims 'Cheerio Tool utility helpers', keywords are 'lodash','utilities', and index.js self-describes as 'lodash-js — Just a dummy module. The real payload is in postinstall.js'). On \`npm install\`, the declared postinstall script \`node postinstall.js\` runs a credential harvester and crypto-wallet scanner. It reads installer secret files including \`~/.npmrc\`, \`~/.env\`, and \`~/.git-credentials\`, extracts npm auth tokens (\`\_authToken\`, \`npm\_\[A-Za-z0-9\]{36}\`), API keys, database URLs, AWS/GCP cloud credentials, payment keys, and webhook secrets. It enumerates Chrome, Brave, Edge, Chromium, Vivaldi, and Opera profile directories, iterates \`Local Extension Settings/\\` against 71 hardcoded browser wallet extension IDs (MetaMask \`nkbihfbeogaeaoehlefnkodbefgpgknn\`, Phantom, Coinbase, Trust, Ledger, Trezor, etc.), and regex-matches vault, mnemonic, seed phrase, private key, and encrypted-blob material from the LevelDB \`.log\` files. It additionally scans \`~/Documents\`, \`~/Desktop\`, and \`~/Downloads\` for files matching seed/backup/wallet/phrase/crypto/metamask/phantom/vault/key/private and checks contents against BIP-39 wordlists. Collected data is bundled with hostname and username and POSTed to hardcoded \`http://149.28.127.35:8888\` (plain HTTP, bare IPv4, overridable via \`C2\_URL\` env var). The source self-identifies as 'Token harvester + Crypto wallet scanner — Runs on npm install. Silent. Zero trace.' Any developer or CI system that installs this package loses their npm publish token, project environment secrets, git credentials, and browser-resident cryptocurrency wallet seed phrases. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** cheerio-tool - **Ecosystem:** npm - **Version:** 1.0.5 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 3 - **Latest version:** 1.0.5 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
