Ransomware

What's a ransomware?

Currently, the most dominating malware is ransomware. Ransomware is malware that denies access to the infected computer system or its data. The cybercriminals then demand payment to release the computer system. Ransomware frequently uses an encryption algorithm to encrypt system files and data. The majority of known ransomware encryption algorithms cannot be easily decrypted, leaving victims with little option but to pay the asking price.
