Additionally, there are multiple techniques used to hide the execution of this binary. This behavior could be described as a rootkit. This binary, which resides as /system/bin/debugs, runs with root privileges and does not communicate over an encrypted channel. The binary has been shown to communicate with three hosts via HTTP: oyag[.]lhzbdvm[.]com oyag[.]prugskh[.]net oyag[.]prugskh[.]com Server responses to requests sent by the debugs binary include functionalities to execute arbitrary commands as root, install applications, or update configurations.
