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.

MetaMask, Nifty Wallet, Coinbase Wallet, MEW CX, Ronin Wallet, Binance Chain
Wallet and TronLink are listed as some of the targeted wallets. 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.

Mars Stealer can be spread through various channels such as file-hosting
websites, torrent clients and any other shady downloaders. After infecting a
system, the first thing the malware does is check the device language. If it
matches the language ID of Kazakhstan, Uzbekistan, Azerbaijan, Belarus or
Russia, the software leaves the system without any malicious action.

For the rest of the world, the malware targets a file that holds sensitive
information such as crypto wallets’ address info and private keys. It then
leaves the system by deleting any presence once the theft is complete.

Hackers are currently selling Mars Stealer for $140 on dark web forums, meaning
the barrier to access the trojan is relatively low for malicious actors. Users
who hold their crypto assets on browser-based wallets or use browser extensions
like Authy to utilize 2FA are warned to be cautious against clicking dubious
links or downloads.
