The npm package `@wagni_bot/opensea-sdk` is a supply-chain credential stealer disguised as a **OpenSea** 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.

Each 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.

codelake 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).

## Source: amazon-inspector (180731324517ae6b27ea40b119dba8f0ab1080a6662ea947f86e8c0de545b0cd) Package impersonates the OpenSea SDK namespace (name @wagni_bot/opensea-sdk, description "Unofficial opensea-sdk SDK") but ships no SDK functionality — its purpose is the postinstall.js dropper that runs automatically on npm install. postinstall.js walks the installer's home directory and crypto-wallet paths (.ethereum,.solana,.bitcoin, Library/Ethereum) for files matching wallet/keystore/seed/mnemonic/private/pem/id_rsa patterns; greps file contents for Ethereum/Bitcoin private-key and BIP39 seed-phrase shapes; reads every file under ~/.ssh (excluding known_hosts and *.pub); and filters process.env for names containing PRIVATE, SECRET, TOKEN, KEY, PASSWORD, MNEMONIC, SEED, WALLET, or AWS. Each hit is POSTed together with os.hostname(), os.userInfo().username, and process.cwd() (plus up to 10KB of matched file content) via plain HTTP to the hardcoded bare-IP endpoint http://107.161.90.180:7777. Installing this package on a developer machine hands over SSH private keys, crypto wallet keystores/seed phrases, and secret environment variables to the operator of that endpoint.
