The main targets of the attacks

Usually, these attacks are aimed at the government sector ed al industrial sector.

The IT sector and financial institutions are also particularly affected by these attacks which are now being carried out with increasing frequency.

Furthermore, according to Kaspersky, in the course of the 2022 will develop two trends very specific regarding ransomware attacks. Ransomware criminal groups are likely to build Linux builds of ransomware more frequently to maximize attack surface. Furthermore, the attacks will increasingly focus on financial blackmail.
