The ransomware extortion landscape through the first part of 2026 has continued to evolve in some predictable and some less-predictable ways. The threat intelligence reporting from the major reporting bodies, the incident response findings from the major IR firms, and the operational telemetry from the major security platforms together paint a consistent enough picture to be worth a working read.

The headline observations.

The total volume of public ransomware incidents reported through victim shaming sites, regulatory disclosures, and threat intelligence reporting has been at a similar level to the same period in 2025. The shape of the activity has shifted within that broadly consistent total.

The big-game-hunting model — large enterprise victims, large ransom demands, sustained extortion pressure — has continued to be the centre of gravity for the most operationally significant threat actor groups. The headline-grabbing incidents through Q1 2026 have followed this pattern.

The pure-encryption extortion model has continued to give ground to the data-extortion and data-leak model. The proportion of incidents where the threat actor is primarily extorting on the basis of stolen data rather than encryption has continued to grow. The reasons are operational — data extortion is technically easier than maintaining reliable encryption-based extortion, the victim’s ability to recover from backups is irrelevant to a data-leak extortion, and the public-relations and regulatory pressure on the victim of a data leak is often higher than the pressure of operational disruption alone.

The double-extortion model where both encryption and data-leak threats are used remains the most common pattern but the share of pure-data-extortion incidents has grown.

The threat actor landscape.

The most operationally active threat actor groups through Q1 2026 are mostly continuations of groups that have been active for several years. The brand reshuffling and the takedown-and-rebrand cycle has continued. Law enforcement actions through 2024–2026 have produced some meaningful disruptions but the operational tempo of ransomware activity has not been broken.

The geographic distribution of threat actor operating bases has been broadly consistent with prior years. The Russia-and-CIS-based ransomware ecosystem remains the dominant single concentration. The smaller ransomware operations originating from other geographies have been noted but have not approached the scale of the major Eastern European groups.

The relationship between ransomware activity and broader state-aligned cyber activity has continued to be a focus of intelligence analysis. The lines between criminal-motivated ransomware operations and state-tolerated or state-supported activity have remained blurred in some operations. The policy and law enforcement response to this ambiguity continues to develop.

The targeted sector picture.

The healthcare sector has continued to be a heavily targeted vertical. The combination of high data sensitivity, time-critical operational disruption, and often-constrained security budgets has kept the sector attractive to ransomware operators. The major healthcare incidents through Q1 2026 have continued to expose the operational fragility of some healthcare networks.

The education sector has been similarly targeted. The combination of large user populations, federated identity architectures, and constrained budgets has produced a steady incident rate.

The manufacturing and industrial sector incidents have continued. The operational technology exposure in manufacturing environments has been a focus of incident response findings.

The financial services sector has been generally less impacted than other sectors. The security investment and operational maturity in financial services has produced better resilience but the sector has not been immune.

The local government and small public sector entity exposure has been a continued concern. The capacity of smaller entities to maintain operational security at the level required to deter modern ransomware operators is limited and the incident rate has reflected this.

The attack technique picture.

The initial access patterns have been broadly consistent with recent reporting. Credential theft from infostealer operations followed by purchase or trade on access-broker markets has continued to be a major initial access pathway. Vulnerability exploitation, particularly of edge devices and remote access infrastructure, has continued. Phishing-driven initial access has continued but has decreased as a share of total initial access compared to credential-based access.

The lateral movement and privilege escalation techniques have been broadly consistent. The use of standard administrative tooling for lateral movement, the abuse of legitimate remote management software, and the exploitation of identity infrastructure all remain dominant patterns.

The defensive picture.

The defensive responses across the major reporting incidents have shown improvement in some areas. The use of immutable and air-gapped backup strategies has reduced the impact of pure-encryption extortion. The investment in identity and access infrastructure has reduced the impact of credential-based initial access in better-prepared organisations.

The areas where defensive practice continues to lag include endpoint detection and response coverage in operational technology environments, identity hygiene in legacy identity infrastructure, and the speed of detection and response in the critical first hours of an incident.

The regulatory and policy picture.

The Australian regulatory environment for ransomware-related disclosure has continued to develop. The Cyber Security Act and the related reporting frameworks have produced more visibility on incident patterns than was available in earlier years. The Critical Infrastructure regime has been a continued operational consideration for affected entities.

The international policy work on ransomware — the Counter Ransomware Initiative, the various law enforcement collaborations, the financial sanctions and asset seizure actions — has continued. The cumulative effect on threat actor operations has been real but limited.

The outlook for the rest of 2026.

The realistic outlook is that ransomware activity will continue at broadly the current operating tempo through the rest of the year. The technical and operational evolution of threat actor activity will continue. The defensive practice will continue to improve at uneven pace across sectors. The major incidents that hit the headlines will continue to be a mix of well-prepared organisations under heavy attack and less-prepared organisations exposed by inadequate security posture.

The work for defenders remains the same as it has been — identity hygiene, backup integrity, detection and response capability, and incident response readiness. The organisations that do these well have a meaningfully better chance of avoiding the worst outcomes when they are targeted. The organisations that do not are continuing to be exposed.
