The VoidCrypt Ransomware, also known as Chaos Ransomware, it uses both AES and RSA algorithms for encrypting data. The ransom note provides multiple email addresses to contact the threat actor and states the victim has 48 hours to pay or the ransom will double. It appends ".void" to infected files and stops multiple services before encrypting files.
