Global Ransomware Groups Hit Record High as Smaller Threat Actors Emerge

 

The number of active ransomware groups has reached an unprecedented high, marking a new phase in the global cyber threat landscape. According to GuidePoint Security’s latest Ransomware & Cyber Threat Report, the total number of active groups surged 57%, climbing from 49 in the third quarter of 2024 to an all-time peak of 77. Despite this sharp rise, the number of victims has remained consistent, averaging between 1,500 and 1,600 per quarter since late last year. 

The United States continues to bear the brunt of these attacks, accounting for 56% of all reported victims. Germany and the United Kingdom followed distantly at 5% and 4%, respectively. Manufacturing, technology, and the legal sectors were among the hardest hit, with the manufacturing industry alone reporting 252 publicly claimed attacks in the second quarter—a 26% increase from the previous quarter. 

GuidePoint’s senior threat intelligence analyst, Nick Hyatt, noted that while the overall ransomware volume has stabilized, the number of distinct groups is soaring. He explained that this growth reflects both the consolidation of experienced threat actors under major ransomware-as-a-service (RaaS) platforms and the influx of newer, less skilled operators trying to gain traction in the ecosystem. 

Among the most active groups, Qilin led with a dramatic 318% year-over-year surge, claiming 234 victims this quarter. Akira followed with 130 victims, while IncRansom—first detected in August 2023—emerged as the third most active group after a sharp increase in attacks. Another rising player, SafePay, has steadily expanded its operations since its appearance in late 2024, now linked to 258 victims across 29 industries and 30 countries in 2025 alone. 

GuidePoint’s researchers also observed a growing number of unclaimed or unattributed ransomware attacks, suggesting that many threat actors are either newly formed or deliberately avoiding public identification. This trend points to an increasingly fragmented and unpredictable ransomware environment. 

While the stabilization in overall attack numbers might appear reassuring, experts warn against complacency. The rapid diversification of ransomware groups and the proliferation of smaller, anonymous actors underline the evolving sophistication of cybercrime. As Hyatt emphasized, this “new normal” reflects a sustained, adaptive threat landscape that demands continuous vigilance, proactive defense strategies, and cross-industry collaboration to mitigate future risks.

Black Basta Targets Microsoft Teams with New Ransomware Tactics

 

The Black Basta ransomware group has resurfaced with a concerning method of spreading file-encrypting malware, now targeting Microsoft Teams. The group, notorious for cyberattacks on technology, finance, and public sector industries, exploits the popular collaboration platform to infiltrate networks.

First observed in October 2024, this new tactic shows a shift from previous approaches. Active since April 2022, Black Basta initially used spam and social engineering to distribute malware. Now, they impersonate IT support staff or colleagues, tricking users into providing credentials for fake network logins, enabling the deployment of malware. This deceptive method replaces older techniques like phone-based social engineering.

Microsoft Teams is a strategic target due to its global use in corporate communication. Many employees trust messages within the platform, often overlooking verification steps. This makes them more vulnerable to attackers who exploit this trust to gain unauthorized access.

In 2023, Black Basta was connected to email phishing campaigns involving links to malicious websites. While those campaigns focused on harvesting credentials and delivering malware, the group's shift to real-time platforms like Teams indicates a significant evolution in their strategy.

Microsoft urges users to exercise caution with suspicious messages, especially those requesting sensitive information or financial transactions. "If a message in Teams appears to ask for credentials or money transfers, users are advised to verify the sender’s identity through other channels," the company recommended. Avoiding unknown links and confirming requests through phone or email are key practices to prevent such attacks.
