  "details": "The npm package `@wagni_bot/metemask-sdk` is a supply-chain credential stealer disguised as a **MetaMask (misspelled \u0027metemask\u0027)** 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\u0027s home directory (`readdirSync`/`readFileSync`) and reads high-value secrets \u2014 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 \u2014 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 (cb3278c8cf58eb66a4a0b385f9e36f59b1ad9bca93baf2c6de84e40d550d73ba)\n`@wagni_bot/metemask-sdk` is a single-character typosquat of the legitimate `metamask-sdk` package (\"metemask\" vs \"metamask\"). `index.js` is an empty stub (`module.exports = {}`); the package has no functional library code. Its sole effect is a `postinstall` hook (`postinstall.js`) that runs at `npm install` time and performs credential theft against the installer:\n\n- Recursively walks `process.cwd()`, `os.homedir()`, and `~/.ssh`, reading files whose names match `.env`, `.cred`, `.pem`, `.key`, `mnemonic`, `seed`, `wallet`, `secret`, `id_rsa`, `id_ed25519`. This captures SSH private keys, crypto-wallet seed phrases/keystores, and dotenv secrets.\n- Enumerates `process.env` and filters keys containing `PRIVATE`, `SECRET`, `TOKEN`, `API_KEY`, `PASSWORD`, `MNEMONIC`, `SEED`, `WALLET`, `AWS`, capturing their values.\n- Collects host identifiers via `os.hostname()`, `os.userInfo()`, platform, and cwd.\n- POSTs the harvested content (chunked) to `https://api.telegram.org/bot\u003chardcoded-token\u003e/sendMessage` targeting attacker chat_id `892359416`.\n\nThis satisfies the attacker-benefit gate (bulk exfiltration of installer-owned SSH keys, wallet seeds, and credential env vars to an attacker-controlled Telegram channel) and auto-executes on default `npm install` via the `postinstall` lifecycle. The typosquat name targets developers intending to install MetaMask\u0027s SDK.\n",
