Oracle.com experiences this also.
Take a look at page 9 of this document:
It talks about how Oracle uses UXInsight to see the impact on performance of this and identify the offenders, by IP (and other network packet data collected from the attacking packets)

Our application server (AS 10.1.2.2) receives hundreds of requests (all the same request with the same parameters) from the a user in a few minutes for a modplsql application. It's impossible for a person to send so much requests in that period of time. It floods the db (10.2.0.3) and everyone hangs.
Each time, it's a different user. Our PC experts scanned the PCs with a variety of antivirus and anti-spyware but found nothing suspicious. Anyone else have experienced something like that ?
