We were able to establish proof of connection through their shared infrastructure, e.g., IP addresses and C&C servers, and the code similarities between some of the malware families. We first noticed the first Android malware variant (AndroidOS_Mudwater.HRX) when we discovered that its IP address and C&C server, 78[.]129[.]139[.]131, was used as the final C&C server of a MuddyWater campaign. In the said campaign, we saw victims receiving commands for downloading a second stage payload from the abovementioned IP address.
