Malware Alert: New DeerStealer Campaign

A new variant of sophisticated information-stealing malware, DeerStealer, has been identified targeting personal and financial data across infected systems. Using signed binaries, rootkit-like techniques, and deceptive installers (like Adobe Acrobat Reader), it evades detection while maintaining persistence via scheduled tasks.
 
Key highlights:

  • Steals system info, credentials, crypto wallets, browser & app data.
  • Uses obfuscated files and hidden components for stealth.
  • Communicates with C2 servers and can switch servers to avoid detection.
  • Sold and supported on dark-web forums and Telegram channels.
  • Stay vigilant! Always verify downloads and keep security tools updated.
