Check Point researchers they discovered that in the third quarter of 2020, the ransomware gangs that carried out the most attacks were Maze and Ryuk. In fact, the Ryuk ransomware targeted an average of 20 companies per week.

The Ryuk gang intensified its activities in July and focused mainly on organizations health care. It should be noted that hospitals and related organizations face many challenges in recent months due to COVID-19. The ransomware gangs they target them because they know they are likely to succumb and pay the ransom after they systems they can not be closed for a long time.

Check Point says that ransomware attacks increased by 50%, worldwide in the third quarter of 2020. Ryuk and Maze ransomware were the most common threats. In the US, these attacks have almost doubled. The following is a list of countries most affected by ransomware attacks this time:
