Re: spoolss overflow attempt: unknow threat or false alert ?

Hi Martynas,

A few questions -

	1 - What planned changes have happened to the network in recent  
weeks (SOE change, patches, permission changes)?
	2 - When the workstations are rebooted, how long until the packets  
start up? Before the user logs in?
	3 - Did the perimeter network security devices record any odd  
behaviour in the 24-48 hours prior to the first packets being flooded?
	4 - Is there any odd network behaviour between workstations that are  
affected, and those that aren't? (If it is something sneaky, you  
might be lucky and catch it here)

If it is a sneaky attack targeting the alerted SNORT rule, then your  
systems are on their way to being hosed.  Good Luck.

Sincerely,

Carl Jongsma
