MilkyDoor Malware affects Hundreds of Android Apps Available on Google Playstore.

A new android Malware has been found by Trend Micro which it claims is a successor to a Dress Code malware found earlier.

This malware uses port 22 to establish a SSH session with its Command and Control (CnC) server owned by the attacker.

As it uses SSH all the data between the Android phone and its CnC server are encrypted which makes it difficult for the enterprise security infrastructure to detect it. Security solutions cannot detect the data inside the encrypted connection unless they are doing Deep Packet Inspection of SSH traffic.
