{"id":"MAL-2026-10037","summary":"Malicious code in @wagni_bot/web3-toolkit (npm)","details":"\n---\n_-= Per source details.

On execution it walks the user's home directory and OS-specific paths and reads files matching wallet, keystore, seed, mnemonic, and credential patterns — including.env, ~/.npmrc, ~/.aws/credentials, ~/.ssh/id_*, ~/.git-credentials, ~/.netrc, Solana id.json/keypair.json, Ethereum keystores, and browser wallet extension storage for MetaMask (nkbihfbeogaeaoehlefnkodbefgpgknn), Phantom, and similar extensions. It also scans.txt/.md/.rtf/.csv files across Desktop, Documents, and Downloads (including localized directory names), matches contents against an embedded BIP-39 wordlist to detect seed-phrase backups, and POSTs matching file contents plus host/user identifiers (os.hostname(), os.userInfo(), os.homedir()) over plain HTTP to a hardcoded remote endpoint at http://107.161.90.180:7777. The package.json description is empty and the package ships no legitimate functionality; the web3-themed scoped name is a lure targeting crypto developers.\n","modified":"2026-07-09T16:31:51.542804706Z","published":"2026-07-09T15:14:27Z","database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","modified_time":"2026-07-09T15:14:27Z","sha256":"0a07053ee42572578f0fbeab5c9c8551fd2937f1126bc9c71c37546dfdf19edd","import_time":"2026-07-09T16:20:32.665526837Z","id":"IN-MAL-2026-009013","versions":["1.2.0"]},{"import_time":"2026-07-09T16:20:33.667248098Z","source":"amazon-inspector","sha256":"888085b6329d0b35602e7d50bedb0175cdb43dc35b2581b80a7ca5fccc7b7dee","modified_time":"2026-07-09T15:16:36Z","id":"IN-MAL-2026-009027","versions":["1.0.0"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/web3-toolkit/v/1.2.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/web3-toolkit/v/1.0.0"}],"affected":[{"package":{"name":"@wagni_bot/web3-toolkit","ecosystem":"npm","purl":"pkg:npm/%40wagni_bot/web3-toolkit"},"versions":["1.2.0","1.0.0"],"database_specific":{"indicators":{"package_integrity":[{"hashes":{"sha512_sri":"sha512-s8lSeq79K/bmTdruXzFihN/E3vXmKaxz1N7HeifXalx45DSwOBD6PbIq3zDgbJwnwJ3JGTYwIabQm3bOCsTRYQ==","sha1":"0a1a57ea524fac883c113157f3b4e95dd9849145"},"filename":"web3-toolkit-1.2.0.tgz"}],"evidence_files":[{"sha256":"6c9c16897e74d441ac24472d86e97fac219c2fc56f14408ef406b2883df03654","path":"postinstall.js","tlsh":"6712d9c576be111d1427d2bbfa2b0202356eae8a260dd995fcce09002f583945bd7bfc"},{"sha256":"d88d3942aa56e24c3603568ea6c1f6498e09eaa43f9c88d94bb514ac164e0135","path":"package.json","tlsh":"53d05e204d515b3378c81bec0827416baef3490f1008292817db2994434e67b947b62f"}]},"cwes":[{"name":"Embedded Malicious Code","description":"The product contains code that appears to be malicious in nature.","cweId":"CWE-506"},{"name":"Embedded Malicious Code","description":"The product contains code that appears to be malicious in nature.","cweId":"CWE-506"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@wagni_bot/web3-toolkit/MAL-2026-10037.json"}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
