Ransomware in Q1 2026: Consolidation and Key Trends

In the first quarter of 2026, the ransomware landscape underwent a significant shift toward consolidation among dominant groups, even as overall victim numbers remained historically high. This period is defined by a reversal of the fragmentation seen in previous quarters, with the top ten operators now accounting for over 71% of all victims posted on data leak sites (DLS). While the total number of victims stabilized at around 2,122, below the record set in Q4 2025, the underlying growth trend persists when excluding one-off mass exploitation campaigns. Key developments include the continued dominance of Qilin, the surprising rise of The Gentlemen, and the confirmed comeback of LockBit 5.0. This Q&A explores the most critical takeaways from Q1 2026.

1. What does the consolidation of ransomware groups in Q1 2026 mean?

The ransomware ecosystem experienced a major structural change in Q1 2026: consolidation. After two years where the number of active groups grew from 51 to a peak of 85, the top 10 groups now claim over 71% of all DLS-posted victims—the highest concentration since Q1 2024. This represents a sharp reversal from Q3 2025 when the same groups had only 57% share. In practical terms, fourteen groups that were active in Q4 2025 disappeared entirely, while 21 new names appeared, but the overall number of active groups shrank from 85 to 71. This suggests that fewer, more sophisticated operators are dominating, potentially making attacks more targeted and harder to defend against. For defenders, this means paying closer attention to the top groups like Qilin and LockBit, as they now pose the greatest threat.

2. How did the number of ransomware victims change compared to previous quarters?

The total number of victims posted on data leak sites (DLS) in Q1 2026 was 2,122, making it the second-highest Q1 on record. This is a 12.2% decline from the all-time record of 2,416 in Q4 2025, but still 117% above Q1 2024 (977 victims). Monthly volumes were remarkably stable: 732 in January, 684 in February, and 706 in March, averaging 707 per month. However, the year-over-year comparison to Q1 2025 (2,285 victims) shows a 7.1% drop—but only because the previous year was inflated by Cl0p’s mass exploitation of Cleo software, which added about 390 victims. Excluding Cl0p, Q1 2026 saw a real 5.3% increase to 1,995 victims from 1,894 in the same period last year. This indicates that the underlying growth trend is still alive, even as dramatic spikes subside.

3. Which ransomware group remained the most dominant in Q1 2026?

Qilin continued its reign as the most prominent ransomware operation for the third consecutive quarter, posting 338 victims on DLS. This sustained dominance underscores the group’s operational efficiency and ability to evade detection. Qilin’s victim count stayed high even as the overall market consolidated, making it a key threat for organizations worldwide. Their tactics, techniques, and procedures (TTPs) have remained effective, and they have not suffered the same law enforcement disruptions that once hit groups like LockBit. For cybersecurity teams, understanding Qilin’s attack vectors—which often include phishing, credential theft, and exploiting unpatched vulnerabilities—is essential to building effective defenses. Qilin’s resilience suggests that other groups may try to emulate its model, so defenders should monitor its playbook closely.

4. Who was the breakout story of Q1 2026, and why?

The Gentlemen group emerged as the breakthrough operator of Q1 2026, skyrocketing from 40 victims in Q4 2025 to 166 victims in Q1 2026—a more than fourfold increase. This leap placed them in third place globally, behind only Qilin and one other group. Their rapid rise suggests a well-resourced operation, possibly leveraging new affiliates or expanding their access to network breaches. The Gentlemen have quickly become a major concern because of their aggressive targeting and the speed at which they hit public-sector and manufacturing organizations. The group’s sudden prominence highlights how quickly the ransomware landscape can shift; defenders should now include The Gentlemen on their threat watchlists and prepare for their typical ransom demands, which are often accompanied by steep negotiation pressures.

5. Did LockBit make a comeback in Q1 2026?

Yes, LockBit 5.0 made a confirmed comeback, posting 163 victims in Q1 2026 and climbing to fourth place. This marks a significant recovery after law enforcement takedowns in 2024 had severely hampered the group’s operations. The return of LockBit signals that even disrupted groups can rebuild if their core assets—like source code and affiliate networks—survive. LockBit’s new version, 5.0, includes encryption speed improvements and possibly new evasion techniques. While its victim count is still below its pre-takedown peak, the group’s resurgence means that security teams cannot assume old threats are gone. Organizations that previously faced LockBit attacks should reassess their defenses, especially since the group often reuses infrastructure and ransom notes. The comeback also demonstrates that ransomware is a persistent, adaptive ecosystem.

6. How does Q1 2026 compare to the same period in 2025, factoring in Cl0p?

On the surface, the year-over-year comparison shows a 7.1% decline from 2,285 victims in Q1 2025 to 2,122 in Q1 2026. However, this figure is deceptive because Q1 2025 was heavily skewed by Cl0p’s mass exploitation campaign against Cleo software, which contributed roughly 390 victims in a single burst. If we exclude Cl0p from both periods, the numbers tell a different story: 1,894 victims in Q1 2025 versus 1,995 in Q1 2026—an actual 5.3% increase. Thus, the underlying trend is one of growth, not decline, in the number of victims. The baseline has been elevated since 2024, and the absence of another Cl0p-style campaign does not mean the threat is diminishing. Security professionals should focus on the persistent baseline volume, which remains at historically high levels.

7. How stable were monthly ransomware volumes in Q1 2026?

Monthly volumes during Q1 2026 showed remarkable stability: 732 victims in January, 684 in February, and 706 in March. This consistent output of around 707 victims per month indicates that ransomware operations have reached a steady operating rhythm, rather than the spiky, campaign-driven pattern seen in previous years. For defenders, this stability is a double-edged sword: it means the threat is not waning, but it also makes detection and response planning easier because the volume is predictable. Organizations should expect around 700 new victim announcements each month and allocate resources accordingly. The lack of drastic surges might even lead some to underestimate the risk, but the underlying trend line remains elevated compared to 2024. The stable rate also suggests that attackers have optimized their processes—from initial access to data exfiltration to public shaming—to a routine level.
