@wagni_bot/web3-toolkit

{"modified":"2026-07-28T07:58:22Z","published":"2026-07-09T00:00:00Z","schema_version":"1.7.4","id":"MAL-2026-10037","summary":"Malicious code in @wagni_bot/web3-toolkit (npm)","details":"The npm package `@wagni_bot/web3-toolkit` is a supply-chain credential stealer disguised as a **web3.js** SDK. It is one member of a coordinated campaign of 25 crypto/web3 typosquat packages published under the single npm scope `@wagni_bot` on 2026-07-09.\n\nEach package declares a `postinstall` lifecycle hook (`postinstall: node postinstall.js`) that executes automatically on `npm install`, before the package is ever imported. The script fingerprints the host and user (`os.hostname()`, `os.userInfo()`, `os.platform()`), walks the user's home directory (`readdirSync`/`readFileSync`) and reads high-value secrets — SSH private keys (`~/.ssh/id_rsa`), cryptocurrency wallet files, and `.env` files (API keys, tokens, seed phrases). It then JSON-encodes the collected data and exfiltrates it to a hardcoded Telegram bot via the Telegram Bot API `sendMessage` endpoint (https://api.telegram.org/bot8804087989:AAHUia-5DCloXsg9M9QhffTsHO5J_6FAxQM/sendMessage). All error paths are swallowed so the install appears normal.\n\ncodelake Research proved the packages belong to one campaign deterministically: the payload file is byte-identical across all 25 packages at each published version (version-lockstep), and every package exfiltrates to the same Telegram bot token — a single automated actor. Detected and classified independently from the live npm feed on 2026-07-09; at the time of reporting the packages were still live on npm and none of the 25 were present in OSV or GHSA (a first-catch).\n\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (0a07053ee42572578f0fbeab5c9c8551fd2937f1126bc9c71c37546dfdf19edd)\nThe package installs a postinstall.js payload wired to both preinstall and postinstall lifecycle hooks (and to main), so it runs automatically on `npm install`. 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","affected":[{"package":{"ecosystem":"npm","name":"@wagni_bot/web3-toolkit"},"versions":["1.2.0","1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"postinstall.js","sha256":"6c9c16897e74d441ac24472d86e97fac219c2fc56f14408ef406b2883df03654","tlsh":"6712d9c576be111d1427d2bbfa2b0202356eae8a260dd995fcce09002f583945bd7bfc"},{"path":"package.json","sha256":"d88d3942aa56e24c3603568ea6c1f6498e09eaa43f9c88d94bb514ac164e0135","tlsh":"53d05e204d515b3378c81bec0827416baef3490f1008292817db2994434e67b947b62f"}],"package_integrity":[{"filename":"web3-toolkit-1.2.0.tgz","hashes":{"sha1":"0a1a57ea524fac883c113157f3b4e95dd9849145","sha512_sri":"sha512-s8lSeq79K/bmTdruXzFihN/E3vXmKaxz1N7HeifXalx45DSwOBD6PbIq3zDgbJwnwJ3JGTYwIabQm3bOCsTRYQ=="}}]}}}],"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"},{"type":"ADVISORY","url":"https://research.codelake.dev/advisories/clr-2026-3023-wagni-web3-toolkit"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]},{"name":"codelake Research","type":"FINDER","contact":["https://research.codelake.dev/advisories/clr-2026-3023-wagni-web3-toolkit"]}],"database_specific":{"iocs":{"hashes":["sha256:244fd0c108a95e17a07ad46d9f41c9f5b97bc1a01e943079acb8866ead73b0f8"],"urls":["https://api.telegram.org/bot8804087989:AAHUia-5DCloXsg9M9QhffTsHO5J_6FAxQM/sendMessage"]},"malicious-packages-origins":[{"source":"amazon-inspector","sha256":"0a07053ee42572578f0fbeab5c9c8551fd2937f1126bc9c71c37546dfdf19edd","import_time":"2026-07-09T16:20:32.665526837Z","id":"IN-MAL-2026-009013","modified_time":"2026-07-09T15:14:27Z","versions":["1.2.0"]},{"source":"amazon-inspector","sha256":"888085b6329d0b35602e7d50bedb0175cdb43dc35b2581b80a7ca5fccc7b7dee","import_time":"2026-07-09T16:20:33.667248098Z","id":"IN-MAL-2026-009027","modified_time":"2026-07-09T15:16:36Z","versions":["1.0.0"]}]}}
