RANSOMWARE attacks spiked to unprecedented levels in the first quarter of 2025, according to new data from cybersecurity analysts, with a 126 percent year-over-year increase in public extortion cases.
A total of 2,289 victims were listed across 74 ransomware groups’ data leak sites between January and March, far exceeding the 1,011 victims disclosed during the same period in 2024. Even after adjusting for Cl0p’s mass disclosure of 300 victims in February — related to a supply chain exploit targeting Cleo file transfer platforms — attack volumes remain historically high.
