State of ransomware in 2026

Securelist

Kaspersky researchers have identified key trends in ransomware for 2026, indicating a shift in tactics among cybercriminals. One notable trend is the emergence of EDR killers, tools designed to bypass endpoint detection and response systems, making it easier for attackers to operate undetected. Additionally, there is a growing focus on data leaks rather than just data encryption, meaning that attackers might threaten to expose sensitive information instead of simply locking it away. This change could lead to increased pressure on organizations to comply with ransom demands, as the risk of public exposure rises. These trends are significant as they suggest that companies will need to adapt their security strategies to combat evolving ransomware tactics effectively.
