{"id":"MAL-2026-11115","summary":"Malicious code in @wagni_bot/polymarket (npm)","details":"The npm package `@wagni_bot/polymarket` is a supply-chain credential stealer disguised as a **Polymarket** 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.

With no evidence of exfiltration, install-time code execution, silent relay, credential distribution, backdoor, or dropper behavior, there is no supply-chain attack signal to act on.\n","modified":"2026-08-05T06:35:56.204470270Z","published":"2026-07-09T00:00:00Z","database_specific":{"malicious-packages-origins":[{"sha256":"e62513060b0dc26c7b25c64ec0db9a6b903ba4e54310afba01ecbde95f221bf1","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-013223","import_time":"2026-08-05T06:00:55.602693219Z","modified_time":"2026-08-05T05:51:55Z"}],"iocs":{"hashes":["sha256:d45480166a56e98ca6dcba310eced70c6bd0221a8678a29db89458dcae629fc1"],"urls":["https://api.telegram.org/bot8804087989:AAHUia-5DCloXsg9M9QhffTsHO5J_6FAxQM/sendMessage"]}},"references":[{"type":"ADVISORY","url":"https://research.codelake.dev/advisories/clr-2026-3010-wagni-polymarket"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/polymarket/v/1.0.0"}],"affected":[{"package":{"name":"@wagni_bot/polymarket","ecosystem":"npm","purl":"pkg:npm/%40wagni_bot/polymarket"},"versions":["1.0.0"],"database_specific":{"cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"indicators":{"package_integrity":[{"hashes":{"sha1":"2b6a8bd8d816dca718eed419feb9185094639f2f","sha512_sri":"sha512-AbPlFwwih2RgCE5lP9nPdLu0ZYhB5vh09kJzgIgYbOTcv1r4Kh3WX58QSa9MfpugCmP+v/PbCqJg/+7Ze1eDMQ=="},"filename":"polymarket-1.0.0.tgz"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@wagni_bot/polymarket/MAL-2026-11115.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-2026-3010-wagni-polymarket"],"type":"FINDER"}]}
