A record number of companies have been affected by ransomware attacks, and the number of organizations that have agreed to pay a ransom to decrypt data has also increased. Even some publicly available data released by attackers put additional pressure on extortion victims, forcing them to pay.

To last year’s cases Based on this, Unit 42 analysts estimate that the average ransom demanded by cybercriminals rose 144% to $2.2 million, while the average actual payment increased by 78% to $540,000. Retail, healthcare, and manufacturing are the sectors most frequently attacked.
The most active hacker group Conti
The most active hacker group last year was Conti. They accounted for, on average, more than one-fifth of the incidents investigated by Unit 42. In second place is the Revil group with 7.1% of the events. The third place is shared by Hello Kitty and Phobos, which realized 4.8% of the cases.
Some of the proceeds from ransomware were used by attackers to develop new and easier tools for cyber attacks. In this way, zero-day vulnerabilities are increasingly being exploited.
