What is Gamma Ransomware
Gamma is a crypto-extortionist from the Dharma family whose activity came in September of this year. This is a Ransomware that encrypts user files of different formats. By itself, Ransomware is one of the most dangerous threats, which carries a real danger, as this makes your files unusable. After encryption, Gamma changes the extension of your files to .gamma. In fact, it uses such a template .id-(your id).[firstname.lastname@example.org].gamma. Files are encrypted by AES algorithm, therefore independent file recovery is an almost impossible task. The virus creates a special file-note with details of the redemption.
