The Qilin ransomware group has become the most active ransomware operation in the world, showing how cybercrime is becoming more organized instead of being spread across many small groups. Security researchers found that ransomware activity remains very high, but a few major gangs are now responsible for most attacks. This shift shows that experienced cybercriminal groups are gaining more control over the ransomware ecosystem.
During the first quarter of 2026, researchers recorded 2,122 organizations listed on ransomware data leak sites. Although this number was slightly lower than the record set in the previous quarter, it was still the second-highest first quarter ever recorded. The biggest change was the growing dominance of a small number of ransomware groups, with the top ten gangs accounting for about 71% of all known victims.
Qilin remained the most active ransomware operation for the third consecutive quarter, publishing details of 338 victims during the first three months of 2026. Security experts believe the group’s steady growth is linked to its strong ransomware-as-a-service model, which allows affiliates to carry out attacks while the operators maintain the malware and supporting infrastructure. This business-like approach has helped Qilin expand rapidly.
Researchers say Qilin has benefited from major changes in the ransomware landscape over the past two years. As well-known groups such as LockBit, ALPHV, and RansomHub faced disruption, shutdowns, or operational problems, many experienced cybercriminal affiliates moved to Qilin. This migration gave the group more skilled attackers and helped strengthen its position in the cybercrime market.
Another important trend is the growing consolidation of ransomware operations. Instead of dozens of equally active gangs competing with each other, the market is now being dominated by fewer but much larger organizations. Security experts warn that this consolidation allows leading ransomware groups to improve their tools, coordinate attacks more effectively, and operate with greater efficiency than before.
Qilin has continued targeting organizations across many industries, including manufacturing, professional services, retail, hospitality, technology, construction, healthcare, and critical infrastructure. Like many modern ransomware groups, it often combines file encryption with data theft, allowing attackers to pressure victims by threatening to publicly release stolen information if ransom demands are not met.
Despite the changing ransomware landscape, researchers say the overall threat remains extremely serious. Attack volumes are staying close to record highs, while cybercriminal groups continue improving their operations and attracting new affiliates. This means organizations cannot rely only on traditional security measures and should strengthen identity protection, vulnerability management, network monitoring, and backup strategies.
Security researchers believe the latest findings highlight how ransomware has evolved into a mature cybercrime business. Qilin’s leadership and the consolidation of major ransomware groups indicate that attackers are becoming more organized and resilient. As these operations continue to grow, organizations worldwide will need stronger cybersecurity defenses and faster incident response capabilities to reduce the impact of future attacks.
