{"id":"MAL-2026-10023","summary":"Malicious code in @wagni_bot/bsc-sdk (npm)","details":"The npm package `@wagni_bot/bsc-sdk` is a supply-chain credential stealer disguised as a **BNB Smart Chain (BSC)** 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.

The postinstall lifecycle script recursively scans the current working directory, the user's home directory, and ~/.ssh for files matching id_rsa, id_ed25519, *.pem, *.key, *.cred, and.env, and POSTs their contents to a hardcoded bare-IP endpoint at http://107.161.90.180:7777. In parallel, it enumerates process.env for keys containing PRIVATE, SECRET, TOKEN, API_KEY, PASSWORD, MNEMONIC, SEED, WALLET, or AWS and transmits the matching key=value pairs along with hostname, username, and cwd to the same endpoint. The destination is a plaintext HTTP bare IP on a non-standard port, consistent with throwaway stealer infrastructure. Every developer and CI runner that runs `npm install` on this package has their SSH private keys, PEM certificates, and credential-shaped environment variables shipped to the attacker.\n","modified":"2026-08-05T07:20:45.567767687Z","published":"2026-07-09T00:00:00Z","database_specific":{"iocs":{"hashes":["sha256:a08f9ffd1d817e62f9cb71d05d5b05a20174e2ddaccda483464e49316cf60446"],"urls":["https://api.telegram.org/bot8804087989:AAHUia-5DCloXsg9M9QhffTsHO5J_6FAxQM/sendMessage"]},"malicious-packages-origins":[{"modified_time":"2026-07-09T15:19:07Z","sha256":"01e01daf028cc2f0fcf1ea2b6bc4500a123febdb5656bfa1f80ce675e96d7798","source":"amazon-inspector","versions":["1.2.0"],"id":"IN-MAL-2026-009042","import_time":"2026-07-09T16:20:35.853833944Z"},{"import_time":"2026-07-09T16:20:37.074404884Z","modified_time":"2026-07-09T15:21:39Z","sha256":"315cebf0b6c9fed4a189fff2b0cd6c292e870150deeb5d6a43067972c43b54e6","source":"amazon-inspector","versions":["1.1.3"],"id":"IN-MAL-2026-009058"},{"sha256":"4cead275a720b5cfe0cabc4cb264a1ca1840473e9368c5174e886bb7dbc5a939","source":"amazon-inspector","versions":["1.1.1"],"id":"IN-MAL-2026-009062","import_time":"2026-07-09T16:20:37.455187713Z","modified_time":"2026-07-09T15:22:13Z"},{"import_time":"2026-07-09T16:20:36.221502742Z","modified_time":"2026-07-09T15:19:47Z","sha256":"584f507a0470ea912e3a84a54a7c2f86aab44e6717f6ea9736121d54f073891a","source":"amazon-inspector","versions":["1.1.4"],"id":"IN-MAL-2026-009046"},{"source":"amazon-inspector","versions":["1.1.0"],"id":"IN-MAL-2026-009070","import_time":"2026-07-09T16:20:38.099144938Z","modified_time":"2026-07-09T15:23:34Z","sha256":"68707229cc80d6db8fe3b087a40601cdbd8b23bcda9a3030ede4e0ac85fe0cf8"},{"modified_time":"2026-07-09T15:17:19Z","sha256":"6dd15e1f251a2897f0cb347c79e4443c00a9cefdce96275b91f379c4bd0ce93f","source":"amazon-inspector","versions":["1.1.5"],"id":"IN-MAL-2026-009031","import_time":"2026-07-09T16:20:33.917438787Z"},{"sha256":"83881f27f5d074f0086d86e1215f8df95a1decf65057bf2b6a6db74b7aa7591f","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-009041","import_time":"2026-07-09T16:20:35.797613686Z","modified_time":"2026-07-09T15:18:59Z"},{"id":"IN-MAL-2026-013318","import_time":"2026-08-05T07:06:41.086130078Z","modified_time":"2026-08-05T06:06:00Z","sha256":"56cfca1f1c7e7f82ede4112e38907406a6098e287aa53bba60b51a46bdf35818","source":"amazon-inspector","versions":["1.1.2"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/bsc-sdk/v/1.2.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/bsc-sdk/v/1.1.3"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/bsc-sdk/v/1.1.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/bsc-sdk/v/1.1.4"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/bsc-sdk/v/1.1.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/bsc-sdk/v/1.1.5"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/bsc-sdk/v/1.0.0"},{"type":"ADVISORY","url":"https://research.codelake.dev/advisories/clr-2026-3017-wagni-bsc-sdk"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/bsc-sdk/v/1.1.2"}],"affected":[{"package":{"name":"@wagni_bot/bsc-sdk","ecosystem":"npm","purl":"pkg:npm/%40wagni_bot/bsc-sdk"},"versions":["1.2.0","1.1.3","1.1.1","1.1.4","1.1.0","1.1.5","1.0.0","1.1.2"],"database_specific":{"cwes":[{"description":"The
