Ransomware Attack Statistics 2024: Year in Review (Updated 2026)

The ransomware landscape in 2024 delivered a paradox that few predicted. Attack volumes climbed to record highs, yet total ransom payments dropped sharply as more organizations refused to pay. Fueled by 46 new threat groups and high-profile takedowns like Operation Cronos against LockBit, the year reshaped the economics of cyber extortion. This retrospective pulls together the most reliable 2024 ransomware attack statistics from reports published in 2025 and 2026, giving IT leaders a clear picture of what happened and what it means going forward.

Key Ransomware Attack Statistics From 2024

• Researchers recorded 5,414 ransomware attacks globally in 2024, an 11% increase over 2023, according to a Check Point Cyberint annual report published in January 2025.

• Ransomware gangs collected an estimated $813.5 million in payments during 2024, a 35% decline from 2023's record $1.25 billion, per the Chainalysis 2025 Crypto Crime Report.

• 95 distinct ransomware groups were active in 2024, a 40% jump from the prior year, with 46 entirely new groups emerging on the scene.

• The United States absorbed over 50% of all global ransomware attacks, with approximately 2,675 confirmed incidents targeting American organizations.

• Only about 30% of ransom negotiations resulted in actual payments, while the typical final payout settled between $150,000 and $250,000 regardless of the initial demand.

• Healthcare remained the costliest sector, with the average data breach reaching $9.77 million in 2024, marking the 14th consecutive year healthcare led all industries.

• 66% of ransomware attacks resulted in data encryption before defenders could intervene, according to the Sophos State of Ransomware 2025 report.

• The median ransom demand climbed to $2.75 million in 2024, while median actual payments sat at $1.26 million, highlighting the widening gap between what attackers asked for and what victims paid.

• RansomHub emerged as the most active group with 531 claimed victims, overtaking LockBit (522 victims) after law enforcement disruption.

• 65% of financial institutions worldwide reported experiencing a ransomware attack during 2024, nearly double the rate from two years earlier.

Total Attacks Hit Record Highs Despite Payment Declines

The most striking ransomware attack statistic from 2024 is the disconnect between attack volume and revenue. While the number of incidents climbed by double digits, the money flowing to criminal wallets fell by more than a third. The Chainalysis 2025 report attributed this to several converging forces: improved backup strategies, growing law enforcement pressure, and a cultural shift among victims toward refusing payment.

The first half of 2024 actually started hot, with $459.8 million in payments tracking 2.38% ahead of the same period in 2023. But the second half told a different story. On-chain payments slowed dramatically, dropping roughly 35% compared to H1. Law enforcement operations, particularly the February 2024 takedown of LockBit infrastructure through Operation Cronos, played a pivotal role. LockBit's payments fell 79% in the second half of the year according to blockchain analysis.

Meanwhile, the gap between what attackers demanded and what victims ultimately paid widened considerably. In the second half of 2024, there was a 53% difference between initial ransom demands and final settlement amounts, suggesting that even when organizations did pay, they negotiated aggressively to reduce the financial impact.

This dynamic created a dangerous situation for organizations, though. As overall payments declined, ransomware groups compensated by attacking more targets and diversifying their extortion tactics. The Analyst1 year-in-review report, published in January 2025, documented 5,223 extortion claims, a 13% rise over 2023. The message was clear: fewer victims were paying, so attackers simply cast a wider net.

The Ransomware Group Ecosystem Fragmented

One of the defining features of 2024's ransomware attack statistics was the explosion of new threat actors. According to the Check Point Cyberint report, 46 new ransomware groups surfaced during the year, yet their average operational lifespan was just 3.9 months. Only 16 of those 46 groups survived past the six-month mark.

This fragmentation reshaped the threat landscape in important ways. The top 10 groups accounted for 52.8% of all attacks, down from a higher concentration in prior years. RansomHub seized the top position with 531 victims, narrowly edging out LockBit at 522. Play (355 victims), Akira (262), and Hunters International (234) rounded out the top five.

The rapid turnover also made attribution and defense harder. New groups often spun up using leaked or purchased ransomware builders, operated for a few months to collect quick payouts, and then dissolved before law enforcement could respond. The Kaspersky 2025 ransomware report noted that 56 new data leak sites appeared in 2024, double the count from 2023, reflecting this churn.

Healthcare and Financial Services Bore the Heaviest Costs

Industry-level data painted a grim picture for specific sectors. Healthcare organizations faced the highest financial impact, with breach costs averaging $9.77 million per incident throughout 2024. The Sophos State of Ransomware 2025 report found that median remediation costs across all sectors, excluding the ransom itself, reached $3.12 million.

Financial institutions were hit at an alarming rate. Roughly 65% of financial organizations worldwide experienced a ransomware attack in 2024, nearly doubling the rate from just two years prior. The Change Healthcare breach stood out as the single most consequential incident of the year, with the ALPHV/BlackCat group initially demanding $22 million and the breach ultimately affecting approximately 100 million individuals.

The construction sector saw a 50% spike in attacks compared to 2023, while government and defense entities reported 412 ransomware incidents globally. These numbers underscore that no industry was spared, but those with legacy infrastructure, limited security budgets, or high-value data remained the most attractive targets.

Victims Increasingly Refused to Pay

Perhaps the most encouraging trend in 2024's ransomware attack statistics was the growing willingness of victims to refuse ransom demands. The Kaspersky report cited Coveware data showing the payment rate hit a record low of 25% in Q4 2024, down from 29% in Q4 2023. The Chainalysis analysis confirmed that less than half of all recorded incidents resulted in any payment, and when victims did pay, there was a 53% gap between the initial demand and final amount in the second half of the year.

This shift was driven by better organizational preparedness. Sophos found that 73% of ransomware victims recovered their data using backups rather than paying the ransom. Improved incident response playbooks, cyber insurance policies that discouraged payment, and public guidance from agencies like CISA and the FBI all contributed to the trend.

Still, the numbers carried a caveat. While the payment rate dropped, individual payouts could still be enormous. One unnamed Fortune 50 company reportedly paid $75 million to the Dark Angels group in 2024, the largest single ransomware payment ever recorded. And the average ransom payment actually increased to roughly $3.96 million, according to Sophos data, even as fewer organizations chose to pay.

How the Numbers Changed in 2025-2026

The trends that emerged in 2024 have continued to evolve. The Chainalysis 2026 Crypto Crime Report revised 2024's total payments upward to $892 million as late attributions came in, and reported that 2025 payments settled at approximately $820 million, an 8% decline. However, the number of claimed victims surged by another 50% in 2025, and the payment rate potentially dropped to an all-time low of 28%.

The median ransom size spiked 368% from 2024 to 2025, reaching $59,556, suggesting attackers shifted toward higher-volume, higher-demand campaigns. Meanwhile, the economic ripple effects grew more severe. The Jaguar Land Rover ransomware incident in 2025 caused an estimated 1.9 billion British pounds in economic damage, making it the costliest cyber event in UK history.

Law enforcement disruptions continued to bear fruit but also revealed the resilience of the criminal ecosystem. Groups that were taken down in 2024, like LockBit and ALPHV/BlackCat, saw their affiliates scatter to competing operations, fueling the proliferation of new brands and leak sites. The Sophos 2025 survey found that the percentage of attacks stopped before encryption jumped to 47% in early 2025, up from 22% in 2023, indicating that defensive technologies and response capabilities continued to mature.

These evolving numbers reinforce that while defenders made meaningful progress in 2024 by driving down payment rates, the ransomware ecosystem has adapted rather than retreated. Attack volumes continue to climb, new groups replace disrupted ones within weeks, and the collateral damage from each incident extends far beyond the ransom itself.

How Managed IT Services Can Help

The ransomware attack statistics from 2024 make one thing clear: organizations that invested in proactive defense fared significantly better than those that relied on reactive measures alone. The 73% backup recovery rate shows that preparation works, but it requires consistent execution across endpoint protection, network monitoring, patch management, and incident response planning.

This is where a managed IT services partner becomes essential. For small and mid-sized businesses that lack dedicated security operations centers, a managed services provider delivers 24/7 monitoring, automated threat detection, and tested backup and disaster recovery systems. These are exactly the capabilities that separated organizations that recovered quickly in 2024 from those that faced weeks of downtime and millions in costs.

The statistics from 2024 also highlight the importance of employee security awareness training. Many ransomware incidents began with phishing emails or compromised credentials, attack vectors that technical controls alone cannot fully address. A managed IT services partner can implement ongoing training programs, simulated phishing exercises, and access management policies that reduce the likelihood of a successful initial compromise.

With 95 active ransomware groups and 46 new ones emerging in a single year, no organization can afford to treat ransomware as someone else's problem. Partnering with a managed IT services provider ensures that your defenses stay current, your backups are verified, and your response plan is ready before an attack arrives.
