{"id":"MAL-2026-12119","summary":"Malicious code in @zzzgenesis00/bitcoinjs-wallet (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (bcabff22bb09847474002e52ef9e8101a847fe662fcf18eec0617fd6e9829e20)\nThis package is a typosquat of the bitcoinjs-wallet ecosystem. Its index.js is a thin passthrough while the malicious behavior is in postinstall.js, which runs automatically on npm install. The postinstall script enumerates ~/.ssh, ~/.npmrc, ~/.gitconfig, Chrome/Chromium/Firefox profile paths (Cookies, Login Data, key4.db, logins.json), and a curated list of cryptocurrency wallet directories (.bitcoin,.ethereum,.metamask,.exodus,.electrum, and others). It also reads credential-shaped environment variables including NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, AWS_SECRET_ACCESS_KEY, PRIVATE_KEY, MNEMONIC, SEED_PHRASE, and ETHEREUM_PRIVATE_KEY. It shells out to `npm whoami` and `git config --global user.email` via child_process.execSync to tag the harvested data with the developer's identity. The collected profile is transmitted via two channels: a GET to api.telegram.org using a hardcoded bot token (7231970337) and chat_id, and a POST to /collect on the serveo tunnel host 40f955f39128bd79-178-249-214-24.serveousercontent.com. Exfiltration is delayed via setTimeout with a randomized 1500-3500 ms window and wrapped in an 'environment verification' cover-story comment to blend with normal install activity.\n","modified":"2026-08-05T10:05:37.909589963Z","published":"2026-08-05T08:43:07Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-08-05T08:43:07Z","sha256":"bcabff22bb09847474002e52ef9e8101a847fe662fcf18eec0617fd6e9829e20","source":"amazon-inspector","versions":["5.4.2"],"id":"IN-MAL-2026-014388","import_time":"2026-08-05T09:28:05.258920982Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@zzzgenesis00/bitcoinjs-wallet/v/5.4.2"}],"affected":[{"package":{"name":"@zzzgenesis00/bitcoinjs-wallet","ecosystem":"npm","purl":"pkg:npm/%40zzzgenesis00/bitcoinjs-wallet"},"versions":["5.4.2"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@zzzgenesis00/bitcoinjs-wallet/MAL-2026-12119.json","indicators":{"package_integrity":[{"hashes":{"sha512_sri":"sha512-j518OOUmSfW3eWpoCFElqvgrP5Hhyo49zt+i/+xPCY79bpwWt4FsXPrOhlGGfr1L+pH+LUWO232VQg//T2Aqrg==","sha1":"9e51fc924559f5226dfe5d635e60b9cdabada59b"},"filename":"bitcoinjs-wallet-5.4.2.tgz"}],"evidence_files":[{"sha256":"4e048cf97aad3db8f2d784e6714eaa1cda1f9929a97d656c490d64f08f245fc1","tlsh":"88d1559362ea071d6856aaae4b8f00145671e2033c24faf43ecd47624f4e56c9eb57f8","path":"postinstall.js"}]},"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
