In an unexpected shift in the ongoing cyber war, April 2025 recorded a significant decline in ransomware attacks. This drop, analyzed by Comparitech, coincides with apparent infrastructure troubles within one of the most active ransomware groups—RansomHub. The sudden silence from this prolific threat actor may have given temporary relief to industries that have been under constant siege. However, this lull may only represent a strategic repositioning rather than a true retreat.
As cybercriminal gangs continue to adapt, with affiliates possibly jumping ship to more active groups like Qilin, the overall ransomware threat remains. The shakeup also saw new trends in the criminal underworld, including advancements in ransomware features and a shift in the dominance hierarchy of hacker groups.
Snapshot of April 2025: A Temporary Dip in Cyber Chaos
April 2025 saw 479 ransomware attacks—noticeably fewer than previous months:
January: 530 attacks
February: 973 attacks
March: 713 attacks
April: 479 attacks
Out of these, only 39 attacks were confirmed by the victim organizations through official statements. The steep decline is largely attributed to RansomHub’s infrastructure outage on March 31, reported by threat intelligence firm Group-IB. The group appeared to go offline abruptly, ceasing activity throughout April, with no new victims listed on their leak site.
In contrast, Qilin, another ransomware syndicate, experienced a sharp rise in activity—from 45 attacks in March to 67 in April. Experts speculate that former RansomHub affiliates migrated to Qilin, especially as Qilin’s administrator “Haise” resurfaced, promoting a new version of their ransomware toolkit, now including DDoS extortion capabilities.
A report from NCC Group had previously ranked RansomHub among the top actors in March, boasting 62 known attacks. With their sudden disappearance, Qilin became April’s most active gang, followed by:
Akira (62 attacks)
Play (50)
Lynx (32)
NightSpire (22)
High-Profile Targets in April
Despite the general drop, April
Marks & Spencer, the UK retail giant, was hit—possibly by Scattered Spider, the group also responsible for 2023 attacks on MGM and Caesars.
Eu-Rec GmbH, a German recycling firm, was targeted by SafePay, leading to insolvency.
The Oregon Department of Environmental Quality (DEQ) fell victim to Rhysida, which claimed to have stolen 2.5TB of data—a ransom of \$2.7 million was refused.
Sector Breakdown
Government entities: 24 attacks
Healthcare: 22
Education: 14
Businesses: 425
What Undercode Say:
This decline in ransomware activity, though welcomed, is more of a strategic shift than a sign of defeat in the ransomware ecosystem. The digital criminal landscape functions like a black market economy—when one major player stumbles, another rises to fill the vacuum. RansomHub’s infrastructure failure left a power void, and Qilin wasted no time in stepping up, possibly absorbing not just the market share but also its affiliates.
The trend toward hybrid ransomware campaigns, as seen with Qilin’s DDoS extortion features, signals a chilling evolution. It’s no longer just about encrypting files and demanding ransom—now it includes multi-pronged pressure tactics to force compliance. This new level of sophistication increases risk across all sectors, particularly for small to mid-sized organizations that may lack resilient cybersecurity infrastructure.
Furthermore, the low number of confirmed disclosures (39 out of 479) suggests that the majority of businesses either resolved the issue quietly or paid ransoms discreetly. This lack of transparency hinders public understanding of the threat and slows down collective defense mechanisms.
The increase in attacks on healthcare and education—two sectors already under stress—raises significant concerns. These are not just technical breaches but threats to human welfare and the education of future generations.
Meanwhile, the high-profile attacks on Marks & Spencer and DEQ underline that even prominent, resource-equipped institutions are not immune. Scattered Spider’s continued activity underscores the persistence of sophisticated ransomware groups that target critical infrastructure and high-value data.
As we move further into 2025, a key area to monitor will be the consolidation of ransomware operations. Just as corporations merge for strategic advantage, cybercriminals may be doing the same—sharing resources, tools, or even integrating platforms. The cybercrime economy appears to be maturing, and with that comes greater efficiency and danger.
The temporary drop in numbers may offer false hope. What’s likely is not a retreat but a regrouping. The cybersecurity community must treat this decline as a warning—not a victory. It’s a reminder that ransomware isn’t just a threat—it’s an evolving industry.
Fact Checker Results:
RansomHub’s infrastructure outage is verified through Group-IB’s analysis dated April 30.
Qilin’s surge in activity is supported by Comparitech and NCC Group reports.
RansomHub listed no new victims in April, confirming a pause in operations.
Prediction:
The ransomware scene in 2025 is entering a phase of fragmented consolidation—with smaller groups potentially aligning with more structured operations like Qilin. Expect to see a rise in dual-threat extortion methods, especially combining data theft with DDoS and reputational damage. As threat actors become more strategic, law enforcement and cybersecurity responses must evolve from reactive to anticipatory. May 2025 could mark the return of RansomHub or a newly branded successor, further reshuffling the power dynamics in cybercrime.
