Cryptocurrency users are facing a new wave of cyberattacks. Security firms like SlowMist and Sentinel Labs have uncovered two major threats: malicious browser extensions and sophisticated Mac malware.
Fake Browser Extensions: A Sneaky Threat
Over 40 fake Firefox extensions are impersonating popular crypto wallets like MetaMask and Coinbase Wallet. These fake extensions look incredibly realistic, copying branding and reviews to trick users. Once installed, they silently steal your wallet credentials. This campaign has been ongoing for months, with new extensions appearing regularly. Researchers suspect a Russian-speaking group is behind it.
The bottom line? Don’t blindly trust browser extensions, even if they look legit. Thoroughly vet any extension before installing it.
Mac Malware: The Zoom Update Scam
Mac users aren’t immune either. A new malware campaign uses social engineering—tricking you via messages—to get you to download a fake Zoom update. This installs NimDoor malware, which steals your keystrokes, screen recordings, passwords, and crypto wallet data. Another variant, CryptoBot, specifically targets browser wallet extensions. This shows that Macs are increasingly becoming targets for sophisticated attacks.
Best Wallet: A Safer Alternative
Given these threats, a mobile-only wallet like Best Wallet offers a much safer approach. Because it’s only available as a mobile app and doesn’t have a browser extension, it’s immune to these attacks. If you see a Best Wallet browser extension, it’s a fake and should be avoided. Best Wallet also uses advanced multi-party computation (MPC) security to protect your private keys.
Key takeaway: Stick to mobile-only wallets to significantly reduce your risk of falling victim to these attacks. Download the official Best Wallet app for enhanced security./p>
