The main motive of this campaign is to deploy Monero mining malware, also their toolset can be used to steal sensitive information from users and perform other nefarious actions. 

Cryptojacking is a slow and tedious way to generate illicit income, that’s why the actor is using botnet to infect as many devices as possible. “Owning multiple systems for mining is not cheap, so attackers try the next best thing: To remotely compromise devices and use them for mining instead,” according to the report published by Bitdefender researchers.
