New Malware Targets MetaMask and Forty Other Digital Asset Wallets

Users have been cautioned against a new malware designed to appropriate digital assets from browser extension wallets like MetaMask and Coinbase Wallet.

Security was never the sturdy suit of browser-based digital asset wallets to store BTC, ETH, and other virtual assets. Nonetheless, new malware makes the security of online wallets even more intricate by directly targeting digital asset wallets that work as browser extensions including Binance Chain Wallet, MetaMask, and Coinbase Wallet.

Dubbed Mars Stealer by its developers, the new malware is a powerful upgrade on the information-stealing Oski trojan of 2019, as per the security researcher 3xp0rt. It targets over forty browser-based digital asset wallets, along with renowned 2FA extensions, with a grabber function that appropriates private keys of the users.

Coinbase Wallet, MetaMask, Nifty Wallet, Binance Chain Wallet, MEW CX, Ronin Wallet, and TronLink are listed as a couple of the targeted wallets. The security expert emphasizes that the malware can target extensions on Chromium-based browsers except Opera.

Presently, hackers are selling Mars Stealer for around one hundred and forty dollars on dark web forums, signifying the barrier to access the trojan is comparatively low for bad actors. Users who hold their virtual currencies on browser-based crypto wallets or use browser extensions like Authy to utilize 2FA are cautioned to be careful against clicking untrustworthy links or downloads.
