Since October 2015, the Pat Bear Organization (APT-C-37) has launched an organized, planned, and targeted long-term uninterrupted attack against an armed organization. Its attack platform is Windows and Android. Up to now, 360 Beaconlab has captured 32 Android platform attack samples, 13 Windows platform attack samples, and 7 C&C domain names.
