Executive Summary
A report published by NCC Group on September 23, 2026, reveals a significant escalation in global ransomware activity. In August 2026, attacks reached a new annual peak with 1,073 victims, a 12% increase from July. The industrial sector bore the brunt of these attacks, accounting for nearly a third of all incidents. North America remains the most targeted region. The report identifies the Qilin and The Gentlemen ransomware groups as the dominant threats, highlighting the persistent and evolving nature of the ransomware-as-a-service (RaaS) ecosystem.
Threat Overview
The data from August 2026 indicates a relentless and growing ransomware threat. The key statistics include:
- Total Victims: 1,073 organizations, a 12% increase from 973 in July.
- Top Targeted Regions: North America (44%) and Europe (26%).
- Top Targeted Industries: Industrials (31%), Consumer Goods and Services (18%), Healthcare (12%), and Information Technology (11%).
- Most Prolific Groups: Qilin (164 incidents), The Gentlemen (116 incidents), Clop (89 incidents), Dire Wolf (43 incidents), and INC Ransom (43 incidents).
The report notes a continuing trend of double extortion, where attackers not only encrypt data but also steal it and threaten to leak it publicly. In some cases, such as the attack on Manchester Airport Group, attackers are forgoing encryption altogether and focusing solely on data theft and extortion.
Technical Analysis
Ransomware groups like Qilin and Clop employ a variety of TTPs, often starting with phishing or the exploitation of public-facing vulnerabilities.
Common MITRE ATT&CK Techniques
- T1190 - Exploit Public-Facing Application: Many groups, including Clop, are known for exploiting zero-day or n-day vulnerabilities in internet-facing software (e.g., MOVEit Transfer) for initial access.
- T1566 - Phishing: A primary initial access vector for groups like Qilin, often delivering malicious payloads via email.
- T1048 - Exfiltration Over Alternative Protocol: Before encryption, attackers exfiltrate large volumes of sensitive data to their own servers to use as leverage for extortion.
- T1486 - Data Encrypted for Impact: The final stage of a traditional ransomware attack, where files on critical systems are encrypted, rendering them inaccessible and disrupting business operations.
- T1657 - Financial Cryptocurency: Ransom demands are made in cryptocurrency to obfuscate the flow of funds.
Impact Assessment
The record number of attacks underscores the widespread and indiscriminate nature of the ransomware threat. The impact on victim organizations is multi-faceted:
- Financial Loss: Includes costs of remediation, operational downtime, and potential ransom payments.
- Operational Disruption: The encryption of critical systems can halt manufacturing lines, cancel appointments in healthcare, and disrupt supply chains.
- Data Breach and Regulatory Fines: The theft of data triggers data breach notification laws (like GDPR), leading to significant regulatory fines and loss of customer trust.
- Reputational Damage: Being listed on a ransomware group's leak site causes significant harm to a company's brand and reputation.

Cyber Observables — Hunting Hints
Security teams can hunt for general signs of ransomware activity. The following patterns could indicate an intrusion:
*.qilin, *.clopreadme.txt, decrypt-me.txtvssadmin.exe delete shadows /all /quietDetection & Response
- Detection: Use EDR solutions with behavioral detection capabilities to identify and block processes performing rapid file encryption. Canary files (honeypot files) can be placed on file shares; any modification to these files should trigger a high-priority alert. This aligns with D3FEND's
D3-FCR - File Content Rules. - Response: An automated response is key. Upon detecting ransomware-like behavior, the infected endpoint should be immediately isolated from the network to prevent lateral spread. Affected user and service accounts should be disabled. The incident response plan should be activated to assess the scope and begin recovery procedures.
Mitigation
NCC Group recommends organizations prepare a defense plan and conduct tabletop exercises. Key technical mitigations include:
- Patch Management: Prioritize patching of internet-facing systems and critical vulnerabilities known to be exploited by ransomware groups. This is a core part of D3FEND's
D3-SU - Software Update. - Immutable Backups: Maintain a robust backup strategy with offline and immutable copies of data that cannot be deleted or altered by attackers.
- Network Segmentation: Limit the ability of attackers to move laterally by segmenting the network. Critical assets should be on isolated network segments with strict access controls.
- User Training: Conduct regular security awareness training to help employees recognize and report phishing attempts.

Severity increasedNew high-profile victim (ATF) identified; details on emerging Aurora RaaS group and its TTPs provided.
The latest report on the August 2026 ransomware surge identifies the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) as a high-profile victim targeted by the Qilin group. Additionally, the report introduces the emerging Aurora Ransomware-as-a-Service (RaaS) group, active since April 2026. Aurora's typical attack chain involves exploiting VPN vulnerabilities and using stolen credentials for initial access, followed by deploying ransomware payloads. This update provides new insights into the evolving threat landscape and specific actors involved in the record-high ransomware activity.

Severity increasedRansomware attacks surged 50% in Q3 2026, reaching nearly 2,900 incidents, driven by intense rivalry between The Gentlemen and Qilin groups.
A new report from Nord Security reveals a significant escalation in ransomware activity during Q3 2026, with 2,894 attacks documented between July and September. This marks a 50% year-over-year increase and an 8.6% rise from Q2. The surge is primarily attributed to fierce competition between the two most dominant ransomware groups, The Gentlemen (383 attacks) and Qilin (363 attacks), who together accounted for over 25% of all incidents. This rivalry is driving innovation in TTPs and increasing operational tempo, suggesting a new phase of heightened activity in the ransomware landscape.
