NetWire RC, NetWire Netwire is a RAT, its functionality seems focused on password stealing and keylogging, but includes remote control capabilities as well.Keylog files are stored on the infected machine in an obfuscated form. The algorithm is: for i in range(0,num_read): buffer[i] = ((buffer[i]-0x24)^0x9D)&0xFF
