Erhan Kahraman reports in cointelegraph.com that "security was never the strong suit of browser-based crypto wallets to store Bitcoin (BTC), Ether (ETH) and other cryptocurrencies. However, new malware makes the safety of online wallets even more complicated by directly targeting crypto wallets that work as browser extensions such as MetaMask, Binance Chain Wallet or Coinbase Wallet.
Named Mars Stealer by its developers, the new malware is a powerful upgrade on the information-stealing Oski trojan of 2019, according to security researcher 3xp0rt. It targets more than 40 browser-based crypto wallets, along with popular two-factor authentication (2FA) extensions, with a grabber function that steals users’ private keys.
The security expert notes that the malware can target extensions on Chromium-based browsers except Opera. Sadly, it means some of the most common browsers such as Google Chrome, Microsoft Edge and Brave made it to the list. Also, while they are safe from extension-specific attacks, Firefox and Opera are also vulnerable to credential-hijacking.
