The threat actors behind Cuba (aka COLDDRAW) ransomware have received more than $60 million in ransom payments and compromised over 100 entities across the world as of August 2022.

In a new advisory shared by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI), the agencies highlighted a “sharp increase in both the number of compromised U.S. entities and the ransom amounts.”

The ransomware crew, also known as Tropical Scorpius, has been observed targeting financial services, government facilities, healthcare, critical manufacturing, and IT sectors, while simultaneously expanding its tactics to gain initial access and interact with breached networks.

It’s worth noting that despite the name “Cuba,” there is no evidence to suggest that the actors have any connection or affiliation with the island country.

The entry point for the attacks involves the exploitation of known security flaws, phishing, compromised credentials, and legitimate remote desktop protocol (RDP) tools, followed by distributing the ransomware via Hancitor (aka Chanitor).
