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.
The data from August 2026 indicates a relentless and growing ransomware threat. The key statistics include:
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.
Ransomware groups like Qilin and Clop employ a variety of TTPs, often starting with phishing or the exploitation of public-facing vulnerabilities.
The record number of attacks underscores the widespread and indiscriminate nature of the ransomware threat. The impact on victim organizations is multi-faceted:
No specific Indicators of Compromise (IOCs) were provided in the source articles.
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 /quietD3-FCR - File Content Rules.NCC Group recommends organizations prepare a defense plan and conduct tabletop exercises. Key technical mitigations include:
D3-SU - Software Update.New high-profile victim (ATF) identified; details on emerging Aurora RaaS group and its TTPs provided.
Regularly patching software, especially on internet-facing systems, closes vulnerabilities exploited by ransomware groups.
Educating users to identify and report phishing attempts can prevent initial access.
Isolating critical systems can prevent the spread of ransomware across the entire network.
Modern EDR and antivirus solutions can detect and block known ransomware payloads and malicious behaviors.
Against the threat of ransomware, having a robust and tested File Restoration capability is the single most important mitigation. For organizations in highly-targeted sectors like manufacturing, this means implementing a 3-2-1 backup strategy: three copies of critical data, on two different media types, with at least one copy stored off-site and offline (air-gapped) or in immutable cloud storage. This ensures that even if attackers gain full control of the production network and delete local backups, a clean copy of the data is safe and available. Recovery plans must be regularly tested to validate the integrity of backups and the time-to-recovery. This D3FEND technique is the ultimate safety net, allowing an organization to recover from a destructive attack without paying a ransom.
Given that ransomware groups like Clop have had massive success exploiting vulnerabilities in public-facing applications (e.g., MOVEit), a rigorous Software Update and patch management program is a critical preventative measure. Organizations must maintain a complete asset inventory of all internet-facing systems and the software they run. A vulnerability management program should be in place to continuously scan these assets, identify vulnerabilities, and prioritize patching based on severity and evidence of active exploitation (e.g., inclusion in CISA's KEV catalog). For industrial organizations, this must extend to OT environments, where patching needs to be carefully planned and tested to avoid operational disruption. This D3FEND technique directly hardens the attack surface, closing the doors that many ransomware groups use for initial access.
With the rise of double-extortion ransomware, detecting and blocking data exfiltration is as important as preventing encryption. Implementing Outbound Traffic Filtering at the network perimeter is key. This should be configured with a default-deny policy, allowing only known, legitimate traffic to exit the network. For example, servers that have no business communicating directly with the internet should be blocked from doing so. Furthermore, deep packet inspection (DPI) and DLP solutions can be used to inspect allowed outbound traffic for sensitive data patterns or connections to known malicious domains or cloud storage services not sanctioned by the organization. This D3FEND technique can provide a critical alert that an attack is in progress and can, in some cases, prevent the data breach aspect of a ransomware attack, reducing the attacker's leverage.

Every tactic, technique, and sub-technique used in this threat has been identified and mapped to the MITRE ATT&CK framework for consistent, actionable threat language.
Observables and indicators of compromise (IOCs) have been extracted and cataloged. Risk has been assessed and correlated with known threat actors and historical campaigns.
Detection rules, incident response steps, and D3FEND-aligned mitigation strategies are included so your team can act on this intelligence immediately.
Structured threat data is packaged as a STIX 2.1 bundle and can be visualized as an interactive graph — relationships between actors, malware, techniques, and indicators.
Sigma detection rules are derived from the threat techniques in this article and can be converted for deployment across any major SIEM or EDR platform.
