05-21-2023, 02:16 PM I want to know what format do you guys use to communicate with cnc is it json or custom format and why? 05-22-2023, 01:05 AM In my experience JSON is a good format for CNC. It can be exchanged between different programming languages and is easy to work with 05-22-2023, 08:34 AM 05-23-2023, 12:00 AM That is true. You should look into custom protocols for communication (JSON packet header and bytes for the packet body) 05-23-2023, 12:04 AM 05-24-2023, 05:42 AM If you have the time and knowledge to do so, writing your own format using cstructs provides alot more value to your malware. It makes reversing alot harder, it reduces the number of bytes sent, it adds less dependence on external stuff (like JSON libraries), it lets you set limits on data sizes (which means you can make your communication look bigger or smaller than it might normally be), and a myriad of other benefits. For most generic crimeware though, most people will just opt for JSON + TLS and forget about it. |
