Full Details

Google's M-Trends 2026 report, based on over 500,000 hours of Mandiant incident response investigations in 2025, reveals a dramatic acceleration in attack timelines. The time between initial access to an organization's systems and handoff to a secondary threat group has decreased from hours to just 22 seconds over recent years. Exploits were the most common initial infection vector, accounting for 32% of cases, followed by phishing (11%), prior compromise (10%), and stolen credentials (9%). This rapid handoff indicates increasing automation and coordination among threat groups, making detection and response more challenging for organizations.

Why It Matters

The dramatic reduction in handoff time requires organizations to implement real-time detection and automated response capabilities to counter increasingly coordinated and automated attacks.
