DDOS: Shaft Agent to Handler
This signature detects the command string "alive" in a UDP packet from port 18753. This can indicate that a Shaft handler is soliciting a response from a Shaft agent. Attackers can use Shaft, a distributed-denial-of-service (DDoS) attack tool, to flood IP addresses with packets from forged source addresses.
Extended Description
An attacker could control the handler servers and agent hosts to execute Distributed Denial of Service attacks.
