A new report from Sophos reveals a strategic shift in attacks against healthcare: extortion without encryption has tripled since 2023. Attackers are increasingly stealing sensitive patient data to demand ransoms, rather than encrypting systems which triggers immediate alarms and recovery protocols.
Business Impact
This tactic allows attackers to stay undetected longer (higher dwell time) and avoids the complexity of decrypting systems. For healthcare providers, the regulatory fines (HIPAA/GDPR) and reputational damage from a massive data leak can be as costly as operational downtime.
Why It Happened
Improved backup strategies in healthcare have made encryption less effective as a bargaining chip. Attackers have pivoted to weaponizing the privacy of patient data, knowing that the threat of a leak is a powerful extortion tool.
Recommended Executive Action
Shift focus from purely “anti-ransomware” (anti-encryption) tools to Data Loss Prevention (DLP) and outlier detection. Monitor for large, unauthorized data exfiltration events. Ensure patient data is encrypted at rest to mitigate the impact of theft.
