{"id":"MAL-2026-11117","summary":"Malicious code in @wagni_bot/web3 (npm)","details":"The npm package `@wagni_bot/web3` 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.

No lifecycle scripts, credential reads, network beacons to attacker-controlled hosts, dropper patterns, or dependency-chain hijack signals were identified in the reviewed artifacts. The package name is scoped under a personal-looking scope and references 'web3', which can be adjacent to crypto-tooling name spaces sometimes used in supply-chain campaigns, but name proximity alone is not evidence of an attack.\n","modified":"2026-08-05T07:20:49.069847174Z","published":"2026-07-09T00:00:00Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-08-05T06:06:42Z","sha256":"fac6d1b9a5e4f1dde662157a957635dda9c9e5d8870908a9e3a5dd259515c912","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-013323","import_time":"2026-08-05T07:06:41.35532155Z"}],"iocs":{"hashes":["sha256:758d5e20b352c8db926c620a7b5b20bdd194a7cf8b22e93a3d86830bb186f9cb"],"urls":["https://api.telegram.org/bot8804087989:AAHUia-5DCloXsg9M9QhffTsHO5J_6FAxQM/sendMessage"]}},"references":[{"type":"ADVISORY","url":"https://research.codelake.dev/advisories/clr-2026-3021-wagni-web3"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/web3/v/1.0.0"}],"affected":[{"package":{"name":"@wagni_bot/web3","ecosystem":"npm","purl":"pkg:npm/%40wagni_bot/web3"},"versions":["1.0.0"],"database_specific":{"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"package_integrity":[{"filename":"web3-1.0.0.tgz","hashes":{"sha1":"a99be427f0a3b62f6574dacc118c68c8d906377c","sha512_sri":"sha512-btOI2Z/X13oz/TyfSJnzNlN2ZJthiHPUZ2ZcZeiaZTMWgBDwimv2BHfvPX0PEwqh9HSDP9/vYGYBQNqilXpDPw=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@wagni_bot/web3/MAL-2026-11117.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"codelake Research","contact":["https://research.codelake.dev/advisories/clr-2026-3021-wagni-web3"],"type":"FINDER"}]}
