Group-IB identified the 2025 Masked Actors through extensive intelligence, highlighting the scale, sophistication, and impact of these active threat groups across sectors and geographies.
The 2025 top ten masked actors include:
RansomHub – The Ransomware-as-a- Service, RaaS operation that surfaced after ALPHV, BlackCat disappeared. Accounting for nearly a fifth of ransomware victims between February and September 2024, it has quickly become a dominant force, targeting industrial manufacturing and healthcare sectors. GoldFactory – A nefarious mobile banking malware group responsible for GoldPickaxe. iOS, the first known iOS trojan designed to harvest facial recognition data for deepfakeenabled financial fraud. Lazarus – A North Korea-linked threat actor responsible for high-profile attacks on financial institutions and cryptocurrency platforms, with over $ 1.3 billion stolen in 2024 alone.
DragonForce – An emerging hacktivist and ransomware group possibly linked to DragonForce Malaysia, that’ s rapidly expanding its operations globally. It targets governments and corporations across multiple industries. OilRig – A Middle East-based group that’ s been active for over a decade. OilRig specialises in increasingly sophisticated phishing attacks to gain intelligence from finance, energy, telecom, and government entities. MuddyWater – Another Middle East-based group. MuddyWater focuses on cyber espionage campaigns targeting NATOaffiliated nations, particularly through spearphishing campaigns. Brain Cipher – A new Ransomware-as-a- Service, RaaS group that surfaced in mid- 2024. It made headlines after demanding an $ 8 million ransom following an attack on Indonesia’ s national data centre. Boolka – Representing a new wave of cybercriminals, Boolka specialises in exploiting website vulnerabilities. The group’ s evolving stealth tactics and ability to adapt and deploy modular malware causes significant financial and reputational damage that’ s likely affected thousands of businesses and users worldwide.

Group-IB analysed over 1,400 unique samples, suggesting a significant number of affected users and an increasing global reach.
Team TNT – Likely the most prolific Malicious Minds in crypto crime, Team TNT has gained infamy for its relentless cloudfocused cryptojacking and brute-force attacks, targeting Kubernetes, Redis, and Docker environments.
