MassMiner Takes a Kitchen-Sink Approach to Cryptomining

Once the malware has been installed, it sets about mining for Monero and hooking up with a crypto-wallet and mining pool; it also connects with its C2 server for updates, and configures itself to infect other machines on the network. Meanwhile, a short VisualBasic script is used to deploy the malware to compromised Apache Struts servers, and it moves laterally by replicating itself like a worm. MassScan meanwhile passes a list of both private and public IP ranges to scan during execution, to find fresh server targets out on the web that it can break into with the SQLck brute-force tool.
