hi everybody,

i'm doing research for network security incidents in the last 6 months.
i have to find two examples and not just vulnerabilities, actual attacks or attempted attacks...
i've looked in google and found heaps of information about worms,viruses and new exploits..
the most news were stuff like that:
CERT® Advisory CA-2002-12 Format String Vulnerability in ISC DHCPD

but i need more information about attacks and affected companies(resulting effect of the incident on the network and the company owning the network)
any information or links would be nice
cheers,
