According to TechCrunch, "The Cuba ransomware gang extorted more than $60 million in ransom payments from victims between December 2021 and August 2022, a joint advisory from CISA and the FBI has warned.
The latest advisory is a follow-up to a flash alert released by the FBI in December 2021, which revealed that the gang had earned close to $44 million in ransom payments after attacks on more than 49 entities in five critical infrastructure sectors in the United States. Since, the Cuba ransomware gang has brought in an additional $60 million from attacks against 100 organizations globally, almost half of the $145 million it demanded in ransom payments from these victims.
The advisory notes that the group — which cybersecurity compan[ies]y [Security Joes and] Profero previously linked to Russian-speaking hackers — typically extorts victims by threatening to leak stolen data. While this data was typically leaked on Cuba’s dark web leak site, it began selling stolen data on Industrial Spy’s online market in May this year."
