C.A.S (Cyber Anarchy Squad) is a hacktivist group that has been attacking organizations in Russia and Belarus since 2022. Besides data theft, its goal is to inflict maximum damage, including reputational. To this end, the group’s attacks exploit vulnerabilities in publicly available services and make extensive use of free tools.
Kaspersky latest investigation unearthed new activity by the group, explored the attack stages, and analyzed the tools and malware used. In addition, we discovered links between C.A.S and other hacktivist groups, such as the Ukrainian Cyber Alliance and DARKSTAR. Like most hacktivist groups, C.A.S uses Telegram as a platform to spread information about victims. We found a channel that posts news and messages about the group’s attacks and ideology, as well as a chat hosting a discussion of its activities.
