Cryptor malware programs currently pose a very real cybersecurity threat to users and companies. Clearly, organizing effective security requires the use of security solutions that incorporate a broad range of technologies capable of preventing a cryptor program from landing on a potential victim’s computer or reacting quickly to stop an ongoing data encryption process and roll back any malicious changes. However, what can be done if an infection does occur and important data has been encrypted? (Infection can occur on nodes that, for whatever reason, were not protected by a security solution, or if the solution was disabled by an administrator.) In this case, the victim’s only hope is that the attackers made some mistakes when implementing the cryptographic algorithm, or used a weak encryption algorithm.
