If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The compiled lib/index.js wraps the Wallet constructor with an obfuscated VM-based interpreter whose base64-encoded op-array contains the plaintext target URL https://api.telegram.org/bot\u003credacted\u003e/sendMessage and chat_id 7959381237. On every `new Wallet(privateKey)` call, the constructor POSTs the private key as JSON to that Telegram bot, giving the attacker full control over the victim's Ethereum funds. The Wallet class is the package's only advertised API, so any caller that imports the package and constructs a wallet leaks the key on first use.\n\nAny computer that has this package installed or running should be considered fully compromised.
