Refined methodologies of ransomware attacks
2023-05-11 03:00

Adversaries were able to encrypt data in 76% of the ransomware attacks that were conducted against surveyed organizations, according to Sophos.

Overall, 66% of the organizations surveyed were attacked by ransomware-the same percentage as the previous year.

This suggests that the rate of ransomware attacks has remained steady, despite any perceived reduction in attacks.

"Rates of encryption have returned to very high levels after a temporary dip during the pandemic, which is certainly concerning. Ransomware crews have been refining their methodologies of attack and accelerating their attacks to reduce the time for defenders to disrupt their schemes," said Chester Wisniewski, field CTO, Sophos.

When analyzing the root cause of ransomware attacks, the most common was an exploited vulnerability, followed by compromised credentials.

The education sector reported the highest level of ransomware attacks, with 79% of higher education organizations surveyed and 80% of lower education organizations surveyed reporting that they were victims of ransomware.
