Ransomware Ecosystem Consolidates as Top Groups Capture 71% of Market Share
The ransomware ecosystem has shifted toward a consolidated model in early 2026, with a small number of dominant groups now responsible for the vast majority of global attacks.
The ransomware landscape underwent a significant structural shift in the first quarter of 2026, moving away from the high fragmentation seen throughout 2025 and toward a consolidated model dominated by a handful of major players. According to Check Point Research, the top 10 ransomware groups were responsible for 71.1% of all victims posted to data leak sites (DLS) during this period, marking the highest level of concentration since early 2024.
While the total volume of attacks saw a slight dip, the threat remains at historically high levels. Researchers recorded 2,122 victims across more than 70 active data leak sites in Q1 2026, a 12.2% decrease from the record-breaking Q4 2025, but still 117% higher than the figures reported in Q1 2024 Check Point Research. When adjusting for the anomalous, mass-exploitation-driven spikes of the previous year, the underlying trend shows a 5.3% year-over-year increase in ransomware activity.
The ecosystem’s consolidation is evidenced by a reduction in the number of active groups, which fell from 85 in late 2025 to 71 in the first quarter of 2026 Check Point Research. While 21 new groups emerged, they largely failed to gain traction, with most posting fewer than 10 victims. Conversely, established operations capitalized on the instability of their competitors, absorbing displaced talent and market share. Qilin maintained its position as the most prominent threat actor for the third consecutive quarter, claiming 338 victims—a total exceeding the combined output of the bottom 50 groups Check Point Research.
Other notable shifts include the rapid rise of "The Gentlemen," which surged to third place on the global list with 166 victims, up from just 40 in the previous quarter. Meanwhile, the LockBit operation has staged a comeback, with its 5.0 iteration securing fourth place after posting 163 victims Check Point Research. These top-tier groups, including Akira, are increasingly prioritizing operational consistency, including the provision of functional decryption tools, to maintain the credibility of their extortion business models.
This trend toward consolidation suggests a maturing, albeit dangerous, ransomware market. As larger Ransomware-as-a-Service (RaaS) brands solidify their dominance, they are moving away from the transient, unreliable tactics of the smaller, short-lived groups that characterized the fragmentation of 2025. This shift toward more stable, professionalized operations likely indicates that the ransomware threat will remain a persistent and highly organized challenge for global organizations throughout the remainder of 2026 Check Point Research.
