January 2025 marked a pivotal month in the ransomware landscape, with Akira emerging as the most active and dominant threat actor.
The group was responsible for 72 attacks globally, a 60% surge compared to previous months, underscoring its aggressive expansion and technical sophistication.
Akira’s rise is emblematic of the broader evolution of ransomware operations, characterized by advanced malware tactics and targeted exploitation of critical infrastructure vulnerabilities.
Manufacturing Sector and U.S. Among Primary Targets
The Manufacturing sector bore the brunt of Akira’s attacks, reporting 75 incidents globally in January.
This trend reflects ransomware groups’ focus on industries with high-value data and operational dependencies.
The IT sector also saw a significant 60% increase in attacks, driven by its critical role in supply chain operations and data management.
Geographically, the United States remained the most targeted region, with 259 incidents, followed by Canada, the UK, France, and Germany regions known for their robust economies and data-rich enterprises.
Technical Evolution
Akira’s operations have evolved significantly since its emergence in March 2023.
The group employs a Ransomware-as-a-Service (RaaS) model, leveraging affiliates to deploy ransomware while sharing profits with developers.
Recent campaigns utilized Python-based malware for lateral movement within networks and exploited VMware ESXi hypervisors a critical component of virtualized infrastructures via SSH tunneling for persistence and data encryption.
Akira’s hybrid encryption scheme combines ChaCha20 for speed with RSA for secure key exchange, ensuring robust data encryption.
Additionally, its latest variant, “Akira v2,” written in Rust, targets Linux systems and VMware ESXi servers.
According to the Cyfirma, this variant employs advanced obfuscation techniques, further complicating detection and analysis by security experts.
While Akira dominated January’s ransomware landscape, new groups such as MORPHEUS and Gd Lockersec also surfaced.
MORPHEUS shares a codebase with HellCat ransomware, indicating potential collaboration or shared resources.
Gd Lockersec focuses on financial gains while avoiding attacks on specific regions and non-profit organizations.
The surge in ransomware activity highlights the growing sophistication of threat actors and their ability to exploit vulnerabilities across diverse sectors.
The sharp increase in incidents from 280 victims in January 2024 to 510 in January 2025 emphasizes the escalating threat posed by ransomware groups like Akira.
This trend underscores the urgent need for organizations to adopt proactive cybersecurity measures, including regular patching, network segmentation, multi-factor authentication (MFA), and employee training to mitigate risks.
As ransomware groups continue to innovate and expand their operations globally, businesses must prioritize robust defenses to safeguard sensitive data and maintain operational resilience against this evolving cyber threat.
