Ransomware, or "ransomware," exploits security vulnerabilities of a company or individual to encrypt and block its computer systems. Attacks for businesses recorded a sharp increase in 2023 to reach a record level after a lull in 2022.

A survey conducted by Cohesity among 900 IT decision-makers and cybersecurity managers from large Anglo-Saxon companies shows that nearly 80% of respondents say they were victims of a ransomware attack between last July and December. The average cost of an attack was $1.82 million for a business, but the bill rises to $2.6 million if we include the payment of ransoms.
