The Top 10 Most Prevalent MITRE ATT&CK Techniques

The Picus Red Report 2026 analyzed over 1.1 million malicious files and mapped 15.5 million adversarial actions, finding that defense evasion, persistence, and C2 tactics now account for 80% of the top ten techniques. Process Injection (T1055) tops the list for the third consecutive year at 30%, while Sandbox Evasion (T1497) saw explosive growth: LummaC2 now calculates the Euclidean distance and angles of mouse movements to distinguish human operators from sandbox automation. Ransomware took a 38% nosedive as attackers pivot from loud encryption to quiet long-term residency, the era of the “digital parasite.” Picus’s press release has Picus Labs VP Dr. Süleyman Özarslan sum up the business case in one line: “Attackers no longer need to lock your data to monetize it; they just need to steal it.”
