Deloitte Global Cyber Threat Intelligence Report 2025

The 2024 Global Cyber Threat Intelligence Report highlights ransomware as the top threat vector, with emerging groups like RansomHub dominating the scene using ransomware-as-a-service (RaaS) models. Nation-state actors such as APT29 continue advanced cyber-espionage activities, while social engineering and AI-enhanced phishing attacks increasingly threaten organizations worldwide. #RansomHub #APT29 #CyberVolk

Keypoints

  • The annual cybersecurity report typically begins with an executive overview summarizing major trends, followed by detailed sections on threat vectors, initial access techniques, notable threat actor profiles, and data summaries.
  • Main sections also include cross-industry threat analysis, threat vector highlights such as ransomware and social engineering, underground cybercriminal trends, and emerging threat actor insights.
  • Key statistics reveal a 17% increase in ransomware attacks in 2024, the rise of over 30 new ransomware groups, and the average ransomware breach cost reaching $4.91 million.
  • Notable trends include the shift to using stolen credentials for VPN access, growing adoption of AI tools for more sophisticated attacks, and increased collaboration between politically motivated threat actors and ransomware operators.
  • Emerging ransomware groups such as RansomHub leverage an affiliate-friendly RaaS model enabling varied skill levels to participate, complicating attribution and expanding attack scale.
  • Social engineering remains a severe and likely initial access technique, enhanced by AI-generated phishing, resulting in a 1,265% increase in phishing attacks observed during 2024.
  • Nation-state actors like APT29 (Midnight Blizzard), Salt Typhoon, and Volt Typhoon intensified espionage campaigns targeting government and critical infrastructure globally.
  • Cybercriminal underground communities are adapting rapidly through decentralization, encrypted communications, and privacy-centric payment methods despite high-profile law enforcement takedowns.
  • Collaboration between law enforcement and private sector entities has increased, resulting in temporary but impactful disruption of cybercriminal operations, though persistent underground resilience is noted.
  • Recurring themes emphasize the evolving complexity of ransomware and social engineering tactics, the emergence of AI as a force multiplier in cyber threats, and the importance of intelligence-driven defense strategies.
