Well the old flood attack was a small program designed by some blackhats.

Then at a given time, they all entered the same url in the program and
just let it run on their computers.

what the program did, was just goto the website and refresh, stop
goto the website, refresh, stopgoto the website, refresh, stop

well until either the user aborted or the server crasshed due to overload.

later came more hardcore versions that changed proxy servers
pr refresh, meaning a new ip and a new session so websites
with long sessions was a target..

Thats a flood attack, dosent leave a "real log" only a visitor trace and a ip
so if you have had a exceptionel ammount of visitors "check ur stastistics"
then i could have been a possible flood attack..

But the last few days "After 3.8" release alot of vb sites have been attacked with
sql injections. but that shoulndt increase the workload, ewen if they found a loophole.
injections should run as a normal command. check wiki about those.
