Chrome Extension Caught Stealing Crypto-Wallet Private Keys

A Google Chrome extension was caught injecting JavaScript code on web pages to steal passwords and private keys from cryptocurrency wallets and cryptocurrency portals. From a report: The extension is named Shitcoin Wallet (Chrome extension ID: ckkgmccefffnbbalkmbbgebbojjogffn), and was launched last month, on December 9. According to an introductory blog post, Shitcoin Wallet lets users manage Ether (ETH) coins, but also Ethereum ERC20-based tokens — tokens usually issued for ICOs (initial coin offerings). Users can install the Chrome extension and manage ETH coins and ERC20 tokens from within their browser, or they can install a Windows desktop app, if they want to manage their funds from outside a browser’s riskier environment. However, the wallet app wasn’t what it promised to be. Yesterday, Harry Denley, Director of Security at the MyCrypto platform, discovered that the extension contained malicious code. According to Denley, the extension is dangerous to users in two ways. First, any funds (ETH coins and ERC0-based tokens) managed directly inside the extension are at risk.
