REvil and GandCrab ransomware operations highlight critical defensive gaps
German authorities identified two Russian nationals who led GandCrab and REvil ransomware operations that successfully attacked at least 130 German companies between 2019-2021, causing over $40 million in damages. These operations succeeded because organizations lacked adequate incident response capabilities and reliable backup systems to recover from attacks without paying ransoms. The scale of damage demonstrates how ransomware groups exploit weaknesses in business continuity planning and recovery procedures. While law enforcement identification is important, the primary defense against such attacks lies in robust backup strategies and incident response preparedness.
Tactical Insight
Immediate actions

- Establish an incident response team with defined roles and communication protocols
- Deploy endpoint detection and response (EDR) tools across all systems
Long-term improvements
- Develop and regularly test comprehensive business continuity and disaster recovery plans
- Create network segmentation to isolate critical systems from potential ransomware spread
- Establish partnerships with cybersecurity firms for emergency incident response support
Detection and monitoring
- Implement continuous monitoring for suspicious file encryption activities
- Deploy behavioral analytics to detect lateral movement patterns typical of ransomware attacks
