The number of victims that ransomware groups posted on their data leak sites increased by 50% last year according to an analysis by researchers from Palo Alto Networks. Twenty-five new groups also appeared last year but some of them had a short life until they disbanded or rebranded.
Noteworthy trends include the use of exploits for zero-day vulnerabilities in lesser known software such as managed file transfer (MFT) applications, but also for vulnerabilities in popular enterprise products like Citrix or VMware. “2023 presented a thriving and evolving ransomware landscape as reflected in posts from ransomware leak sites,” the Palo Alto researchers said in their report.
