AES.ddos or Dofloo is a backdoor with DDoS functionality that accepts commands encrypted with AES.
- DDoS sends an initial message to the C2 (command and control). This message contains the version of Linux, CPU, MHz, and RAM usage.
- DDoS sends a message every second with the CPU percentage usage and network usage in MBPS to the C2.
- C2 sends commands encrypted with AES.
The attacker must be able to send crafted packets to the target system.
