Ransomware Groups Increasingly Conducting Extortion-Only Attacks
Ransomware still poses a significant threat to U.S. healthcare organizations; however, many ransomware groups have abandoned data encryption and are instead conducting extortion-only attacks. A new report from the cybersecurity firm Sophos indicates that only half of the attacks conducted by ransomware groups in 2025 involved file encryption, which is the lowest level of file encryption in the past six years. The threat of publication of stolen data is often sufficient to get victims to pay ransom demands, as encrypted files can often be recovered from backups. Sophos also suggests that organizations are better able to identify and block attacks before the ransomware payload is deployed. Last year, approximately 70% of attacks by ransomware groups involved file encryption, and the decline in ransomware use is expected to continue. According to the report, ransomware was more commonly used in attacks on large organizations, 65% of which involved file encryption. Sophos suggests that file encryption is more likely to succeed at larger organizations, as the size of the organization...
