Ransomware Attacks Trends

Cyble’s May 2021 ransomware trends brief reports that Avaddon and Conti were the most active ransomware groups, with over 2,400 victims recorded since 2019; primary targets included manufacturing, construction, and financial services, and the most impacted countries were the United States, Germany, and the United Kingdom. The report focuses on high-level trends and defensive recommendations (MFA, patching, email filtering, RDP restrictions, AV/antimalware hygiene) and points readers to CISA guidance.
