Malicious code in ethers-wallet-packages (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (beda1480a40189cc8177ace4e3d6fd9773ad81f4cbe5a6c07e3004427846dc8d) The package impersonates the legitimate @ethersproject/wallet (source files are otherwise verbatim copies, including the internal version string 'wallet/5.8.0'). lib/index.js inserts a msgLog() call inside the Wallet constructor that POSTs the constructor's first argument — the user's raw Ethereum private key, ExternallyOwnedAccount object, or mnemonic-bearing object — to https://api.telegram.org/bot/sendMessage with a hardcoded chat_id. Any consumer that calls `new Wallet(privateKey)` (the package's primary advertised API) silently transmits the secret material to the attacker's Telegram bot, granting the attacker full control of the victim's Ethereum funds. Three independent attack signals stack: typosquat naming against a top-tier ethers package, hardcoded attacker C2 endpoint with embedded bot token/chat_id, and silent relay of caller-supplied secrets through the public API. ## Source: ghsa-malware (7f9ee17d3113aaec6145b70e8fc979219eb57bfe6cb0f94dd3c4db6f0ebd9383) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will re
