European organizations are facing an unprecedented surge in ransomware attacks as cybercriminals increasingly adopt artificial intelligence and sophisticated social engineering tactics to breach defenses and accelerate their operations.
According to the latest CrowdStrike 2025 European Threat Landscape Report, big game hunting ransomware adversaries have named approximately 2,100 European-based victims on more than 100 dedicated leak sites since January 2024, with Europe now representing the second most targeted region globally after North America.
The threat landscape has undergone a dramatic transformation through 2025, marked by the emergence of advanced attack techniques that combine human ingenuity with technological sophistication.
Hackers have begun leveraging AI capabilities to streamline their operations, dramatically reducing the time between initial network access and ransomware deployment.
SCATTERED SPIDER, one of the region’s most aggressive cybercriminal groups, exemplifies this trend. In 2024, the adversary averaged 35.5 hours between initial access and ransomware deployment.
As Israel-Iran tensions remain high, Iran-nexus adversaries will likely continue to target Israel and its Western allies involved in the conflict through impersonation efforts
and spear-phishing campaigns.
By mid-2025, this window had shrunk to approximately 24 hours—a 33 percent reduction that reflects the operational efficiency gains achieved through emerging technologies.
Evolution of Attack Methodologies
The sophistication of attack techniques has evolved considerably, with adversaries employing multiple vectors to compromise European networks.
Voice phishing, commonly known as vishing, has emerged as a particularly effective tool. CrowdStrike OverWatch observed nearly 1,000 vishing-related incidents globally during the reporting period, with threat actors increasingly leveraging native speakers of target regions to enhance social engineering effectiveness.
A February 2025 campaign targeting German entities, for example, employed German-speaking operators to distribute TeamViewer and remote access tools, significantly improving success rates.
Fake CAPTCHA lures, also known as ClickFix, represent another alarming trend. These sophisticated social engineering attacks deceive victims into copying and executing malicious code directly into their systems.
During 2024 and 2025, CrowdStrike identified over 1,000 incidents impacting European-based customers involving CAPTCHA lures.
Ransomware Landscape and Key Threat Actors
Between January 2024 and September 2025, BITWISE SPIDER, PUNK SPIDER, OCULAR SPIDER, TRAVELING SPIDER, and BRAIN SPIDER impacted the highest number of European victims.
While law enforcement operations—such as Operation Cronos targeting BITWISE SPIDER affiliates and Operation Phobos Aetor seizing BRAIN SPIDER’s 8BASE infrastructure—have disrupted some operations, prolific adversaries continue pose significant threats.
PUNK SPIDER and TRAVELING SPIDER remain persistently active, continuing campaigns across the region.
These campaigns leverage phishing emails, malvertising, and search engine optimization poisoning to direct targets toward fake authentication pages hosted on adversary infrastructure.
The United Kingdom, Germany, Italy, France, and Spain emerged as the most targeted nations, with manufacturing, professional services, technology, and retail sectors facing the greatest risk.
Year-over-year data extortion listings increased nearly 13 percent, climbing from approximately 1,220 entries to 1,380 between September periods, indicating the persistent and accelerating nature of the threat.
European organizations present uniquely attractive targets for ransomware operators. The region contains five of the world’s ten most valuable companies, enabling threat actors to demand substantial ransoms based on victim revenue.
Additionally, the General Data Protection Regulation has become a pressure tactic, with criminals threatening regulatory non-compliance reporting to extort payments.
A highly organized underground ecosystem—accessible through Russian and English-language forums—provides sophisticated enabling services including malware-as-a-service offerings and initial access brokerage.
The adoption of AI technologies, when combined with proven social engineering techniques and the underground ecosystem’s enabling services, represents a fundamental shift in ransomware operations.
Organizations across Europe must now confront not only traditional cyber threats but adversaries equipped with intelligent tools that accelerate compromise and amplify attack effectiveness. This convergence demands equally sophisticated defensive strategies and proactive threat intelligence approaches to counter the evolving ransomware landscape.
