Service scanner attempting to connect to same port on multiple computers
|service-scan (5253)||Low Risk|
By attempting to connect to the same port on many different computers, an attacker can attempt to determine which computers are running a particular service within a network. This information could be useful to an attacker in performing an attack.
In performing such a scan, an attacker may attempt to avoid detection by using a slow connection rate.
Investigate the source of this event for a possible intruder. Consider blocking all packets originating from the source network.
