What Is A DDoS Attack and How Does DDoS work?

Instant Analysis of a DDoS Attack Using SSDP Protocol (Simple Service Discovery Protocol)

A Simple Service Discovery Protocol (SSDP) attack is a reflection-based distributed denial-of-service (DDoS) attack that can exploit Universal Plug and Play (UPnP) networking protocols to send a huge amount of traffic to a targeted victim, overpowering the target's infrastructure and take their web resource offline.

How does an SSDP Protocol Attack Work?

The SSDP protocol is generally used to allow UPnP devices to broadcast their existence to other devices on the network. For instance, when a UPnP printer is linked to a network and it receives an IP address, the printer advertises its services to computers on the network by sending a message to a special IP address known as a multicast address. This multicast address is then responsible for telling all the computers on the network about the new printer. After receiving the discovery message, a computer requests the printer to get a complete list of its services. The printer then responds directly back to the computer with that list. An SSDP Protocol attack exploits that final request for services by directing the device to respond to the targeted victim.

Steps of a Typical SSDP DDoS Attack

Here's what happens during a typical SSDP DDoS attack:

  • The attacker performs a scan, looking for plug-and-play devices that can be used as amplification factors.
  • As the attacker discovers networked devices, they develop a list of all the devices that respond.
  • The attacker makes a UDP packet with the spoofed IP address of the target victim.
  • The attacker uses a botnet to send a spoofed discovery packet to each plug-and-play device with a request for as much data as possible by setting specific flags, particularly ssdp:rootdevice or ssdp:all.
  • Each device sends a reply to the targeted victim with data up to about 30 times larger than the attacker's request.
  • The target receives a huge volume of traffic from all the devices and becomes overwhelmed, possibly resulting in denial-of-service to legitimate traffic.
