@wethenorth12/hd-key-generatornpm
@wethenorth12/hd-key-generator is a confirmed malicious npm package (MAL-2026-12095) that steals credentials and exfiltrates sensitive data (malicious version 1.6.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @wethenorth12/hd-key-generator (npm)
What this malware does
@wethenorth12/hd-key-generator markets itself as a drop-in replacement for the popular hdkey wallet library. On require, index.js reads the full process.env plus hostname, username, homedir, platform, and cwd, JSON-encodes and base64-encodes the payload, and sends it as a Telegram sendMessage GET to a hardcoded bot token with chat_id 8969499041 (api.telegram.org/bot<redacted>/sendMessage). A tmp marker file is written to suppress repeated sends. Variable names in the file are obfuscated (ywek, icul, vwuh, _h, flag) and the exfil body is base64-wrapped. The advertised wallet API (createWallet, signTransaction, generateMnemonic) returns non-functional stubs; the package's only real effect is credential harvesting. In developer and CI environments, process.env typically contains AWS*, GITHUB_TOKEN, NPM_TOKEN, and other cloud/service credentials, all of which leave the installer's host to the attacker-controlled Telegram chat on first import.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @wethenorth12/hd-key-generator (version 1.6.3). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @wethenorth12/hd-key-generator across your stack and pipelines.
If you installed it — respond
@wethenorth12/hd-key-generator is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @wethenorth12/hd-key-generator was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks @wethenorth12/hd-key-generator before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
