Ransomware Revenue Declines for Second Year Despite 50% Surge in Attacks

According to Chainalysis, whole on-chain ransomware funds fell by round 8% in 2025, marking the second consecutive annual decline.

Despite this drop, claimed assaults rose 50%. The report notes that the widening hole between the rise in incidents and decrease payouts highlights the advanced forces reshaping the ransomware financial system.

Ransomware Payments Reach $820 Million in 2025

In the ransomware chapter of its 2026 Crypto Crime Report, Chainalysis disclosed that ransomware actors collected greater than $820 million in on-chain funds in 2025. The determine represents an 8% year-over-year decline from the agency’s revised 2024 estimate of $892 million.

Even as whole funds confirmed relative stability, ransomware exercise intensified sharply. Data from eCrime.ch signifies that claimed ransomware victims elevated 50% 12 months over 12 months in 2025, making it probably the most lively 12 months on report. Despite the surge in attacks, the share of ransoms paid fell to twenty-eight%, a report low.

Chainalysis cited a number of components behind the divergence. Improved incident response and tighter regulatory oversight have helped cut back the frequency of payouts.

Furthermore, worldwide enforcement efforts towards these actors and laundering networks have constrained some income flows. 

“In some circumstances, the introduction of strains like VolkLocker, notable for a cryptographic weak spot that allowed free decryption in some circumstances, illustrates how technical vetting by defenders can sometimes disrupt a ransomware pressure,” the report learn.

Bitcoin Remains Top Choice as Ransomware Median Payments Soar

While whole funds stagnated, median ransom sizes rose sharply in 2025. The median cost surged 368%, climbing from $12,738 in 2024 to $59,556 in 2025.

Jacqueline Koven, Head of Cyber Threat Intelligence at Chainalysis, instructed BeInCrypto that the median cost is probably going pushed up by a small variety of comparatively high outlier funds relatively than a return to big-game looking ransomware ways that dominated in the previous.

“Ransomware actors are opportunistic, and we proceed to see victimization of organizations of all sizes,” she stated.

Koven additionally revealed that Bitcoin (BTC) stays the financial rail of choice for ransomware actors. She defined that regardless of its transparency, which poses a danger to unhealthy actors, they like BTC as a result of it’s cross-border, instantaneous, liquid, and straightforward to make use of.

“Bitcoin remains to be most well-liked for ransomware funds,” she added.

$14 Million Paid to Initial Access Brokers as Ransomware Pipeline Expands

The report additionally defined that ransomware operations are supported by a wider cybercriminal ecosystem that features Initial Access Brokers and different specialised service suppliers. These brokers facilitate entry to compromised networks, permitting associates to deploy ransomware with relative ease.

Chainalysis estimates that Initial Access Brokers acquired not less than $14 million in on-chain funds in 2025, a determine largely unchanged from the earlier 12 months. While small in comparison with total ransomware revenues, the funds spotlight the “important enabling perform.”

“It is vital to notice that not all IAB funds are made by ransomware operators. IABs actually commerce and purchase accesses amongst themselves and a few malicious actors have TTPs and aims aside from ransomware. Another vital caveat is that not all ransomware incidents will be traced to preliminary entry brokers – there are a variety of various methods to realize entry to sufferer networks. With these caveats in thoughts, we will draw a connection between legal investments and the ransomware assaults that observe,” Chainalysis stated.

The report added that IAB exercise can function a number one indicator. According to on-chain evaluation, surges in IAB inflows are inclined to precede will increase in ransomware payouts and sufferer leaks by roughly 30 days.

“IAB funds are a strong glimpse into the ransomware ecosystem as a result of at the same time as ransomware teams have fragmented and rebranded, as we notice in our report, dependencies on IABs stay fixed. In that means, IAB and even infrastructure funds can sign assault preparation,” Koven talked about to BeInCrypto.

Chainalysis burdened the ransomware story of 2025 can’t be understood by income figures alone. While whole on-chain funds declined modestly, the size, sophistication, and strategic affect of assaults continued to broaden. Organizations of all sizes, from world automakers to regional healthcare suppliers, confronted extortion that disrupted operations, eroded belief, and generated systemic losses far exceeding recorded ransom funds.
