DESCRIPTION:Since malware evolved with time\, they established communicati
 ons with a server to work smoothly. Most of them always used the gold old 
 “client/server” model. Before diving into the malware ecosystem\, I'll
  explain why threat actors just reused communications channels that we hav
 e for thousands of years. Their goal remains the same except that\, today
 \, bits and bytes are used.\nThat’s the basics of a botnet where we have
  “bots” waiting for commands from their master. I’ll provide a recap
  of the C2 protocols from the past to today and... tomorrow? To show you c
 ommon tactics used by attackers to interact with the infected computers.
