Introduction: The Race Between Attackers and Defenders Is Accelerating
For years, Endpoint Detection and Response (EDR) platforms have been one of the strongest defensive technologies protecting organizations from ransomware. Security teams relied on these tools to detect malicious behavior, isolate infected systems, and stop encryption before catastrophic damage occurred. However, the cybercriminal landscape has dramatically evolved. Today’s ransomware groups no longer simply evade security—they actively destroy it before launching their attacks.
The latest Halcyon Q2 2026 Ransomware Evolution Report paints a concerning picture of an industry undergoing rapid transformation. Modern ransomware operators are becoming more organized, more intelligent, and increasingly automated. Artificial intelligence is no longer an experimental tool for attackers—it has become an operational asset that accelerates intrusions, improves social engineering, and even assists during ransom negotiations.
Although the total number of ransomware incidents declined slightly during the second quarter of 2026, cybersecurity experts warn that organizations should not interpret this as good news. Instead, attackers are becoming significantly more efficient, requiring fewer attacks to achieve greater financial and operational impact.
EDR-Kill Is No Longer an Advanced Technique
One of the
Only a few years ago, successfully shutting down enterprise-grade EDR software required sophisticated malware development and deep knowledge of Windows internals. Today, that capability has become standard among leading ransomware operators.
Once security monitoring is disabled, defenders lose valuable visibility into attacker activities. This dramatically reduces the opportunity to detect lateral movement, privilege escalation, credential theft, and ransomware deployment before encryption begins.
Instead of fighting against security software, attackers now eliminate it entirely.
The Gentlemen: A Rapidly Rising Ransomware Threat
Among the fastest-growing ransomware groups identified by Halcyon is The Gentlemen, which rapidly climbed the rankings to become one of the world’s most active ransomware operations during June 2026.
Rather than developing every component from scratch, the group systematically studies successful ransomware families including:
Babuk
Qilin
LockBit 5.0
Medusa
Researchers discovered that developers reverse-engineer these ransomware families to identify the strongest encryption algorithms, stealth techniques, code obfuscation methods, and EDR bypass mechanisms before integrating the best components into their own malware.
This “best-of-all-worlds” development model allows newer ransomware groups to evolve far faster than traditional malware families.
Attack Numbers Declined, But Attack Quality Improved
Halcyon documented 1,988 publicly claimed ransomware attacks conducted by 89 active ransomware groups targeting organizations across 101 countries during Q2 2026.
While this represents a 5.7% decrease compared to the previous quarter, the reduction in attack volume hides a far more dangerous trend.
Modern ransomware operations have become:
Faster
More automated
More stealthy
Better coordinated
More resilient against detection
Instead of launching large numbers of less effective attacks, cybercriminals are investing in higher-quality operations with greater success rates.
The Most Active Ransomware Groups of Q2 2026
According to
Qilin – 293 claimed attacks
The Gentlemen – 214 attacks
DragonForce – 143 attacks
Akira – 119 attacks
LockBit 5.0 – 102 attacks
Interestingly, DragonForce and LockBit experienced renewed activity, while The Gentlemen briefly surpassed Qilin during June, highlighting the rapidly changing hierarchy within the ransomware ecosystem.
Researchers also identified emerging threats including:
KryBit
Payload
PEAR
World Leaks
These newer groups demonstrate that ransomware development continues despite law enforcement disruptions.
Manufacturing Remains the Favorite Target
Manufacturing continued to be the
Other heavily targeted sectors included:
Construction
Business Services
Retail
Software
Manufacturing organizations remain attractive because production downtime often translates directly into significant financial losses, making victims more likely to pay ransoms quickly.
Edge Device Vulnerabilities Continue Opening the Front Door
Attackers continue exploiting internet-facing infrastructure to obtain initial access.
Frequently abused vulnerabilities included:
Citrix NetScaler ADC & Gateway (CVE-2025-5777)
SonicWall SSL VPN (CVE-2024-40766)
Fortinet FortiOS (CVE-2024-55591)
Edge devices remain particularly attractive because they are directly exposed to the internet and frequently contain high-privilege administrative access into enterprise networks.
Delayed patching continues to provide ransomware operators with reliable entry points.
From Initial Breach to Encryption in Less Than One Hour
One of the most concerning findings is the shrinking timeline between compromise and ransomware deployment.
Groups such as DragonForce and Akira have demonstrated the ability to move from initial access to full encryption in under sixty minutes.
Traditional incident response often assumes defenders have several hours—or even days—to investigate suspicious activity.
That assumption is becoming dangerously outdated.
Organizations now need near real-time visibility and automated containment capabilities to interrupt attacks before encryption begins.
Artificial Intelligence Is Becoming an Operational Weapon
The report highlights a significant shift in how cybercriminals employ artificial intelligence.
Rather than simply experimenting with AI-generated phishing emails, attackers are integrating AI throughout nearly every stage of the ransomware lifecycle.
Examples include:
AI-generated malware development
Intelligent phishing campaigns
Automated reconnaissance
AI-assisted victim negotiations
Adaptive social engineering
Autonomous attack decision-making
This evolution enables ransomware operators to scale attacks while reducing the technical expertise previously required.
EvilAI Malware Disguises Itself as Productivity Software
Researchers observed increasing activity involving EvilAI, an LLM-developed malware family disguised as AI productivity applications.
Victims believe they are installing useful AI software designed to improve productivity.
Instead, the application silently grants attackers remote access to corporate environments, providing the foothold required for later ransomware deployment.
The popularity of AI tools across businesses creates an ideal environment for these deceptive campaigns.
Agentic Ransomware Marks a Dangerous Milestone
Perhaps the most groundbreaking development is the emergence of what researchers believe may be the first agentic ransomware.
Unlike traditional malware that simply follows predefined instructions, agentic ransomware can autonomously perform portions of an intrusion, including:
System discovery
Target prioritization
Credential collection
Environmental analysis
Attack sequencing
Although still in its early stages, this represents a major shift toward partially autonomous cyberattacks.
Future ransomware variants may require significantly less direct human control.
Cyber Resilience Is Becoming More Important Than Prevention Alone
Halcyon’s researchers argue that organizations must rethink their defensive strategies.
If attackers routinely disable endpoint protection before encryption, relying exclusively on prevention becomes increasingly risky.
Cyber resilience now includes:
Immutable backups
Network segmentation
Identity protection
Rapid recovery procedures
Continuous monitoring
Incident response rehearsals
Zero Trust architecture
Organizations capable of recovering quickly may become far less attractive ransomware targets.
Nation-State Interests and Criminal Ransomware Are Converging
The report also highlights growing evidence that ransomware operations are increasingly serving geopolitical objectives.
Researchers observed Iran-linked actors disguising espionage campaigns as financially motivated ransomware attacks.
This convergence complicates attribution because organizations may initially believe they are facing ordinary cybercriminals when the true objective involves intelligence collection or strategic disruption.
As geopolitical tensions continue to influence cyberspace, ransomware may increasingly become a hybrid tool combining criminal profit with state-sponsored objectives.
Deep Analysis
The evolution described in Halcyon’s report demonstrates that ransomware has entered an automation era. Attackers are reducing manual effort while increasing operational speed through AI-assisted decision making and standardized EDR-kill modules. The combination significantly shortens defenders’ response windows.
Organizations should focus on proactive detection rather than reactive investigation. Monitoring for EDR service termination, suspicious driver loading, and unauthorized security configuration changes can provide early warning before encryption begins.
Recommended Defensive Commands (Windows)
Check Windows Defender status
Get-MpComputerStatus
List running security-related services
Get-Service | Where-Object {$_.DisplayName -match "Defender|EDR|Security"}
Review recently stopped services
Get-WinEvent -LogName System | Where-Object {$_.Id -eq 7036}
List active network connections
netstat -ano
Identify suspicious processes
Get-Process | Sort CPU -Descending
Review local administrator accounts
net localgroup administrators
Search PowerShell Operational logs
Get-WinEvent -LogName Microsoft-Windows-PowerShell/Operational
These commands are useful for defensive monitoring, incident response, and identifying suspicious activity following a potential compromise.
What Undercode Say:
The Halcyon report confirms a trend that cybersecurity researchers have been warning about throughout 2026: ransomware groups are evolving into highly organized software development teams rather than loose collections of cybercriminals.
The democratization of EDR-kill techniques is perhaps the report’s most significant finding.
Only elite ransomware operations previously possessed the expertise required to disable enterprise security software.
Today, those capabilities are becoming standardized modules that can be integrated into nearly any ransomware family.
This dramatically lowers the barrier to entry.
Artificial intelligence is accelerating that transformation.
Instead of replacing hackers, AI is multiplying their productivity.
Every stage of the attack chain—from reconnaissance to negotiation—is becoming faster.
The appearance of agentic ransomware deserves particular attention.
Autonomous malware capable of making limited decisions represents the next logical evolution of cybercrime.
Although current implementations remain relatively simple, future versions will almost certainly become more adaptive.
Organizations should assume attackers will continue reducing human involvement.
Automation also means attacks can occur simultaneously against hundreds of victims.
Security teams cannot manually investigate every alert.
Detection engineering, behavioral analytics, and automated response will become increasingly essential.
The report also reinforces an uncomfortable reality.
Attack counts alone no longer measure cyber risk.
Fewer attacks can still produce greater financial damage if each intrusion becomes more efficient.
The continued exploitation of VPNs and edge appliances highlights another recurring issue.
Many organizations still struggle with vulnerability management.
Internet-facing systems remain one of the weakest security layers.
Attack timelines shrinking below one hour fundamentally change incident response expectations.
Security operations centers must detect suspicious behavior almost immediately.
Waiting for traditional indicators of compromise may already be too late.
Cyber resilience therefore becomes just as important as prevention.
Recovery capabilities now determine business survival.
Organizations should regularly test backup restoration rather than simply assuming backups work.
Executive leadership should also recognize that ransomware has become a business continuity problem—not merely an IT problem.
Finally, the convergence between nation-state operations and ransomware suggests attribution will become increasingly difficult.
Financial motives and geopolitical objectives may coexist within the same campaign.
The cybersecurity industry should expect ransomware groups to continue borrowing techniques from intelligence agencies while intelligence agencies borrow operational cover from ransomware gangs.
The distinction between cybercrime and cyber warfare will continue to blur.
✅ Verified:
✅ Verified: The report documents 1,988 publicly claimed ransomware attacks across 89 active groups during Q2 2026 and notes that attackers are adopting AI across multiple stages of the ransomware lifecycle.
✅ Verified with Context: While overall ransomware attack claims declined by 5.7% compared to the previous quarter, researchers emphasize that attacks have become faster, more automated, and considerably more difficult to detect, meaning reduced volume does not equate to reduced risk.
Prediction
(+1) AI-powered defensive technologies will increasingly evolve to detect EDR-kill behavior in real time, using behavioral analytics, kernel-level monitoring, and automated isolation to counter ransomware before encryption begins. At the same time, organizations that adopt Zero Trust architectures, immutable backups, continuous threat hunting, and AI-assisted security operations will significantly improve their resilience against the next generation of autonomous ransomware campaigns.
