// 01Executive summary
Immediate attention is required for cloud account and email compromises, which constitute 58% of observed incidents, highlighting a critical need to bolster cloud identity security and enhance visibility. Organizations in Manufacturing, Professional Services, IT, Finance, Construction, and Healthcare are primary targets, reflecting a focus on supply chain infrastructure. Pro-Russian hacktivists pose an urgent threat to NATO member states. Key TTPs include DNS tunneling (T1071.004), SSL C2 (T1071.001), privileged credential misuse (T1078), social engineering via fake recruitment, and the exploitation of RDP/VPN for initial access. Rapid detection and response to these vectors and TTPs, including lateral movement via RDP and persistence using Kerberoasting and Mimikatz, are paramount to mitigate ongoing threats.
