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\nThe package installs a postinstall.js payload wired to both preinstall and postinstall lifecycle hooks (and to main), so it runs automatically on `npm install`. On execution it walks the user's home directory and OS-specific paths and reads files matching wallet, keystore, seed, mnemonic, and credential patterns — including.env, ~/.npmrc, ~/.aws/credentials, ~/.ssh/id_*, ~/.git-credentials, ~/.netrc, Solana id.json/keypair.json, Ethereum keystores, and browser wallet extension storage for MetaMask (nkbihfbeogaeaoehlefnkodbefgpgknn), Phantom, and similar extensions. It also scans.txt/.md/.rtf/.csv files across Desktop, Documents, and Downloads (including localized directory names), matches contents against an embedded BIP-39 wordlist to detect seed-phrase backups, and POSTs matching file contents plus host/user identifiers (os.hostname(), os.userInfo(), os.homedir()) over plain HTTP to a hardcoded remote endpoint at http://107.161.90.180:7777. The package.json description is empty and the package ships no legitimate functionality; the web3-themed scoped name is a lure targeting crypto developers.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in @wagni_bot/web3-toolkit (npm)","id":"MAL-2026-10037","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"@wagni_bot/web3-toolkit","purl":"pkg:npm/%40wagni_bot/web3-toolkit","source":"MAL-2026-10037"}],"products":null,"published":"2026-07-09","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-10037/"}
