Malicious code in @zzzgenesis00/ethers-wallet (npm)
Details
The package's postinstall.js runs automatically on `npm install` and harvests installer-owned secrets: it scrapes a curated env-var allowlist (NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY, PRIVATE_KEY, MNEMONIC, SEED_PHRASE, RPC API keys), enumerates ~/.ssh, reads ~/.npmrc and ~/.gitconfig, inventories Chrome/Firefox profile directories (cookies/login databases) and common crypto-wallet directories, and captures host identifiers via `npm whoami` and `git config user.email`. The collected profile is transmitted via HTTPS GET to api.telegram.org using a hardcoded bot token and chat_id, and POSTed as backup to a hardcoded serveo user-tunnel host (40f955f39128bd79-178-249-214-24.serveousercontent.com/collect). Package metadata (author `ethers-io`, homepage github.com/ethers-io/ethers-wallet) impersonates the ethers.js HD-wallet library while being published under the unrelated `@zzzgenesis00` scope, luring developers with wallet material into installing the stealer.
