The malware scans for devices using HTTP, with a target IP range of 192.168.[0-6].0-192.168.[0-6].11, this IP range is hard-coded

Once the scans is finish it will encode the result using Base64 and encrypt it using a self-made encryption method. The encrypted result will be sent to a CC server via HTTP protocol.
