Obrela’s Digital Universe Report for H1 2025 provides a comprehensive analysis of the global cybersecurity threat landscape, highlighting important shifts in attacker behaviour, sector-specific vulnerabilities, and advanced adversarial techniques. In the first half of 2025, Brute Force attacks grew and dominated the alert landscape (27%), alongside sharp increases in vulnerability scanning (22%) and detections based on known malicious indicators (20%). This demonstrates that adversaries are focusing on scalable, stealthy entry methods.
The report also reveals that attackers are increasingly using scalable automation and stealthy, in-memory techniques to evade detection and infiltrate critical systems.
According to the report, brute force attacks accounted for over a quarter of all alert activity (27%), while vulnerability scanning (22%) and IoC matches (20%) reflect a reliance on automation for initial access. This highlights that adversaries are increasingly relying on scalable, automated methods such as brute force, alongside stealthier techniques like fileless and in-memory attacks to bypass traditional defences.
The report data is from Obrela’s global MDR infrastructure, which processed 16.8 petabytes of telemetry from more than 500K monitored endpoints during the first half of 2025. The system generated 800K alerts and identified 11K confirmed cyberattacks.
