Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Cactus on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

About this groupFirst seen 2023-07-03

cactus

According to ransomware.live, The CACTUS ransomware is said to have emerged around March 2023. The group became known for exploiting vulnerabilities to gain initial access and maintain a presence within the organization's infrastructure. There is little known information about the ransomware group, except that it emerged on the mentioned date and, following encryption, a text file named 'cAcTuS.readme.txt' would be created. Additionally, encrypted files were altered to the '.cts1' extension, and data exfiltration and victim extortion were conducted through the use of the service known as Tox.
