The crypto clipper focuses on “high-value financial artifacts” from the clipboard, including BIP39 mnemonic seed phrases and Bitcoin and Ethereum private keys. It also replaces copied wallet addresses with attacker-controlled ones across Bitcoin, Tron and Monero and takes screenshots every ten seconds for additional context.

Microsoft Defender Antivirus detects the malware as Trojan:Win32/CryptoBandits.A.

Microsoft recommended:

  • Disabling autoplay on removable media
  • Blocking .lnk execution from USB drives
  • Monitoring for proxy activity and spawned scripts

2026 has seen a significant escalation in Windows-based crypto stealers. A new Windows malware strain called Lucid Stealer that targets browser extensions and crypto wallets was identified earlier this month by the Foresiet Threat Intel Team.
