{"id":"MAL-2026-10028","summary":"Malicious code in @wagni_bot/metemask-sdk (npm)","details":"The npm package `@wagni_bot/metemask-sdk` is a supply-chain credential stealer disguised as a **MetaMask (misspelled 'metemask')** 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.

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's SDK.\n","modified":"2026-08-05T06:35:55.062014676Z","published":"2026-07-09T00:00:00Z","database_specific":{"iocs":{"urls":["https://api.telegram.org/bot8804087989:AAHUia-5DCloXsg9M9QhffTsHO5J_6FAxQM/sendMessage"],"hashes":["sha256:5867a4645ba3bf832a6511e27195ec5073a4ab3142405bf2dab493b8a8a1dbb9"]},"malicious-packages-origins":[{"sha256":"0970ff01982fabbf6fe10079a50e89ec0847d3edad5f643b17dbecd70321ae10","source":"amazon-inspector","versions":["1.1.5"],"id":"IN-MAL-2026-009078","import_time":"2026-07-09T16:20:38.872477506Z","modified_time":"2026-07-09T15:24:51Z"},{"id":"IN-MAL-2026-009039","import_time":"2026-07-09T16:20:35.228102701Z","modified_time":"2026-07-09T15:18:36Z","sha256":"c734022f34f31176059d3fc16b4750750d6b5f1dbef1662bbd151d29c38d657c","source":"amazon-inspector","versions":["1.1.1"]},{"versions":["1.0.0"],"id":"IN-MAL-2026-009024","import_time":"2026-07-09T16:20:33.409512406Z","modified_time":"2026-07-09T15:16:12Z","sha256":"cb3278c8cf58eb66a4a0b385f9e36f59b1ad9bca93baf2c6de84e40d550d73ba","source":"amazon-inspector"},{"versions":["1.2.0"],"id":"IN-MAL-2026-009016","import_time":"2026-07-09T16:20:32.881751701Z","modified_time":"2026-07-09T15:14:53Z","sha256":"f02eb354580eaed07d89cb6015f54f3e97d47891a69f8e420bbd42203e4ea3c3","source":"amazon-inspector"},{"versions":["1.1.4"],"id":"IN-MAL-2026-009053","import_time":"2026-07-09T16:20:36.688386301Z","modified_time":"2026-07-09T15:20:49Z","sha256":"2f1619378d1a86aeccaa082b41b58319d72fae1a8dea02d8f5ba60e1284338c2","source":"amazon-inspector"},{"sha256":"6772612dd322662e3f6daab985ad1378d380dc8d0e59e10406ebab4de146aa1d","source":"amazon-inspector","versions":["1.1.3"],"id":"IN-MAL-2026-009033","import_time":"2026-07-09T16:20:34.07294792Z","modified_time":"2026-07-09T15:17:39Z"},{"source":"amazon-inspector","versions":["1.1.0"],"id":"IN-MAL-2026-009069","import_time":"2026-07-09T16:20:38.027527392Z","modified_time":"2026-07-09T15:23:25Z","sha256":"b33bbb63be9b14ef0ee3f0041fc8225e2d272c24a1651ffa1b27a8f4876e1975"},{"modified_time":"2026-08-05T05:12:40Z","sha256":"7593ac939532972b2db1618d0ff347cf68b286638ffc8dcfd1bde3f5f9855e49","source":"amazon-inspector","versions":["1.1.2"],"id":"IN-MAL-2026-012952","import_time":"2026-08-05T06:00:23.675751458Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/metemask-sdk/v/1.1.5"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/metemask-sdk/v/1.1.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/metemask-sdk/v/1.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/metemask-sdk/v/1.2.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/metemask-sdk/v/1.1.4"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/metemask-sdk/v/1.1.3"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/metemask-sdk/v/1.1.0"},{"type":"ADVISORY","url":"https://research.codelake.dev/advisories/clr-2026-3000-wagni-metemask-sdk"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/metemask-sdk/v/1.1.2"}],"affected":[{"package":{"name":"@wagni_bot/metemask-sdk","ecosystem":"npm","purl":"pkg:npm/%40wagni_bot/metemask-sdk"},"versions":["1.1.5","1.1.1","1.0.0","1.2.0","1.1.4","1.1.3","1.1.0","1.1.2"],"database_specific":{"indicators":{"package_integrity":[{"filename":"metemask-sdk-1.1.5.tgz","hashes":{"sha1":"3200bd5a61c869dc3e1d28f4b807f7e91941d93f","sha512_sri":"sha512-zmzp/T7cTFk75etUN4mNQqhIfjmyN1/dKQtmsRAaCPfhMpZtfYWx/8h20k04CO9d1z8KEAI9deylC8WgJL8wEQ=="}}],"evidence_files":[{"sha256":"3d8a59e627a451040c959870dace8fb417d1f9c55c6e2d2190637289212f8b3f","tlsh":"5c8155c4b1fa520958a341eefa5b220210717d573848e4a9fedc9f456f56240af53bfc","path":"postinstall.js"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@wagni_bot/metemask-sdk/MAL-2026-10028.json","cwes":[{"description":"The
