10 Critical Insights into Ransomware Trends – Q1 2026

Ransomware activity in the first quarter of 2026 delivered a mix of expected stability and surprising shifts. While victim counts remain near record highs, the real story lies in the changing structure of the threat landscape. After years of fragmentation, the ecosystem is consolidating around a handful of powerful groups. Here are ten essential facts to understand the current state of ransomware.

1. The Top 10 Groups Now Control 71% of All Attacks

The biggest change in Q1 2026 is market consolidation. The ten leading ransomware operations were responsible for 71.1% of all victims posted on data leak sites (DLS). This is a sharp reversal from the fragmentation seen in late 2025, when the top 10 share had fallen to 57%. The number of active groups dropped from 85 to 71, as smaller players disappeared or were absorbed. Fourteen groups that posted victims in Q4 2025 vanished entirely, while 21 new names emerged—but none gained significant traction. This concentration of power makes it easier for defenders to track threats but also means the remaining groups wield outsized influence.

2. Victim Numbers Stabilize at Historically High Levels

A total of 2,122 victims were posted on DLS in Q1 2026, making it the second-highest first quarter on record. While this represents a 7.1% drop from Q1 2025’s 2,285 victims, that decline is misleading. Excluding Cl0p’s massive Cleo exploitation campaign—which alone added ~390 victims in Q1 2025—the underlying count actually rose 5.3% year over year (see item 6). Monthly volumes were remarkably consistent: 732 in January, 684 in February, 706 in March, averaging 707 per month. This stability suggests ransomware operations have found a sustainable rhythm at a very high baseline.

3. Qilin Maintains Dominance for a Third Straight Quarter

Qilin remains the most prolific ransomware operation, posting 338 victims in Q1 2026. This marks the third consecutive quarter at the top of the list. Their sustained activity shows no signs of slowing, with a consistent victim count that far outpaces rivals. Qilin’s success comes from a streamlined affiliate model and aggressive data leak site operations. While law enforcement has disrupted other groups, Qilin has proven resilient. Defenders should expect this group to remain a primary threat as long as its infrastructure stays intact.

4. The Gentlemen Become the Breakout Story of the Quarter

Perhaps the most surprising development is the meteoric rise of The Gentlemen. This group jumped from 40 victims in Q4 2025 to 166 in Q1 2026, vaulting into third place globally. Their victim count increased more than fourfold in just three months. The Gentlemen appear to have expanded rapidly, possibly recruiting disillusioned affiliates from smaller defunct groups. Their aggressive posting schedule and broad targeting make them a new force to watch. If they maintain this pace, they could challenge Qilin for the top spot later in 2026.

5. LockBit 5.0 Stages a Comeback

After a period of decline following law enforcement takedowns, LockBit has returned with version 5.0. In Q1 2026, LockBit posted 163 victims, climbing to fourth place. That’s up from a lower standing in late 2025. The new version includes improved encryption and evasion techniques. LockBit’s brand recognition and affiliate network give it a strong foundation for resurgence. However, its victim count is still below its historical peak, and the group faces stiff competition from Qilin and The Gentlemen.

6. The Real Growth Trend Is Still Positive

Headline year-over-year comparisons show a 7.1% decline in victims, but that figure is skewed by Cl0p’s one-time mass exploitation in Q1 2025. When Cl0p is excluded from both periods, victim counts were 1,894 in Q1 2025 versus 1,995 in Q1 2026—an actual 5.3% increase. This underlying growth is more indicative of the persistent upward pressure from ransomware. The ecosystem continues to expand in capacity and reach, even if the most dramatic spikes have subsided. Coupled with the high monthly stability (item 2), the trend lines remain concerning.

7. Monthly Victim Counts Show Remarkable Consistency

Throughout Q1 2026, monthly victim postings stayed within a narrow range: 732 in January, 684 in February, 706 in March. This consistent pace of ~707 victims per month suggests that ransomware operations have become industrialized. Groups have standardized their extortion processes, from initial access to data publication. For defenders, this predictability means resource planning can be more precise. But it also indicates that the current security measures are not enough to reduce the overall frequency of attacks.

8. Number of Active Groups Shrinks as Small Players Vanish

The ransomware landscape is becoming less fragmented. The count of active groups posting victims dropped from 85 in Q3 2025 to 71 in Q1 2026. Fourteen groups that were active in Q4 2025 disappeared completely, while only 21 new ones appeared. Many of the new entrants posted very few victims and may not survive. This attrition of small operators is a natural consequence of market consolidation, where successful groups outcompete others for affiliates and access. The overall diversity of threats is decreasing, but the remaining threats are more potent.

9. Fragmentation Reverses After Two Years of Steady Increase

From early 2024 through mid-2025, the ransomware ecosystem experienced continuous fragmentation, with the number of active groups growing from 51 to 85. During that period, the top 10 share of victims fell from 68% to 57%. But Q1 2026 decisively reversed that trend. The top 10 share jumped back to 71.1%, the highest since early 2024 (when the ecosystem was smaller overall). This structural shift indicates a maturing market, where established groups have consolidated their control. Fragmentation was a sign of chaos; consolidation suggests a more organized, perhaps more dangerous, adversary landscape.

10. The Ecosystem Is Shifting Toward Fewer, Larger Operators

The overarching theme of Q1 2026 is consolidation at scale. Fewer groups are responsible for more victims, and the barrier to entry for newcomers appears higher. The concentration of power among a handful of players—Qilin, The Gentlemen, LockBit, and others—likely leads to more sophisticated attacks, better infrastructure, and longer dwell times. While the total number of victims has stabilized, the operational capabilities of the top groups are growing. This shift demands that organizations focus their defenses on the tactics and techniques of these dominant operators, as they will drive the majority of incidents.

Conclusion

Q1 2026 showed that while ransomware volume has hit a plateau, the threat landscape is undergoing a fundamental realignment. The days of dozens of splinter groups are fading, replaced by a concentrated core of highly effective operators. For businesses and security teams, understanding this new dynamic is critical. Focus on the top groups, monitor their evolving methods, and maintain robust backup and response plans. Ransomware is not going away—but its shape is changing.
