  • Attempts to access Bitcoin/ALTCoin wallets;
  • Generates some ICMP traffic;

Unlike passwords and verification codes, fingerprints are fundamental parts of user’s identities. Among the threats blocked on biometric data processing and storage systems is spyware, the malware used in phishing attacks (mostly spyware downloaders and droppers), ransomware, and Banking Trojans as posing the greatest danger.
  • Ciphering the files located on the victim’s hard disk — so the sufferer can no longer utilize the information;
