Who They Target.
About Mikroceen.
In this joint blogpost with fellow researchers from Avast, we provide a technical analysis of a constantly developed RAT that has been used in various targeted campaigns against both public and private subjects since late 2017. We observed multiple instances of attacks involving this RAT, and all of them happened in Central Asia. Among the targeted subjects were several important companies in the telecommunications and gas industries, and governmental entities. Also, we discuss other malware that was typically a part of the attacker’s toolset together with the RAT. The misspelling is intentional, in order to avoid the established microbiological notion, but also to have at least phonemic agreement.
