Re: SQL-worm 1 IP multiple MAC???

Possibly: This MAC Flooding is an ARP Cache Poisoning technique aimed at
network switches. When certain switches are overloaded they often drop
into a "hub" mode. In "hub" mode, the switch is too busy to enforce its
port security features and just broadcasts all network traffic to every
computer in your network.

Hi all,

 

I’ve just found the old SQL-slammer again in my customer network and
notice something that I’ve never notice before:

 

The worm sends UDP packet using 1 static spoof source IP and 1 static
spoof dest IP, but the MAC address changes in every packet (mostly the
source mac).  What is happening here??  Have anybody notice this
before?? 

 

Cheers,

 

-A
