{"id":"MAL-2026-11114","summary":"Malicious code in @wagni_bot/polygon (npm)","details":"The npm package `@wagni_bot/polygon` is a supply-chain credential stealer disguised as a **Polygon** 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 only 3 files scanned and no concrete evidence of exfiltration, install/import-time code execution, credential handling, or network beacons, there is no basis to classify this as a supply-chain attack against installers.\n","modified":"2026-08-05T07:20:49.065118003Z","published":"2026-07-09T00:00:00Z","database_specific":{"iocs":{"urls":["https://api.telegram.org/bot8804087989:AAHUia-5DCloXsg9M9QhffTsHO5J_6FAxQM/sendMessage"],"hashes":["sha256:b35881320cda659f5223a0fb83e3e7d5e4d3bdd1927a25512f99b7ad54790c9e"]},"malicious-packages-origins":[{"modified_time":"2026-08-05T06:07:15Z","sha256":"c111a24195f77b41724bc587e9a6a21718c6197134fd3979617d273e3f0ee4e6","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-013327","import_time":"2026-08-05T07:06:41.590188687Z"}]},"references":[{"type":"ADVISORY","url":"https://research.codelake.dev/advisories/clr-2026-3014-wagni-polygon"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wagni_bot/polygon/v/1.0.0"}],"affected":[{"package":{"name":"@wagni_bot/polygon","ecosystem":"npm","purl":"pkg:npm/%40wagni_bot/polygon"},"versions":["1.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@wagni_bot/polygon/MAL-2026-11114.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"package_integrity":[{"filename":"polygon-1.0.0.tgz","hashes":{"sha1":"2e6057f6e5a1247e6af9f9a787eb241c460daa69","sha512_sri":"sha512-j096Lm6n7UpFiYM0gnYSTfwdONueIMGSN0y/EyHjOwj6Fz+kTPoCUcqC3Ekm1XHsSGYn0FH/w8Mrl65WAAmMdw=="}}]}}}],"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-2026-3014-wagni-polygon"],"type":"FINDER"}]}
