Rewterz Threat Alert – Cuba Ransomware – Active IOCs

Severity

High

Analysis Summary

Cuba – a Windows-based ransomware family – has been active since December 2019. To boost its damage and profitability, the perpetrators recently moved to release the stolen data similar to what we’ve seen previously with other significant ransomware operations. It is delivered by Hancitor malware, a loader notorious for dumping or executing stealers onto victims’ networks, such as RATs and other forms of ransomware. Cuba Ransomware targets companies in the financial, government, healthcare, manufacturing, and information technology industries, infecting Windows computers with the Hancitor malware.
