Well you are plugged into a hub, along with other clients. The hubs are probably then hooked up to a switch. There is software available to sniff packets if you are hooked up directly to a switch, e.g ettercap.

As part of the process of tracking down how it was running, I downloaded a small packet sniffer and ran it so I could attempt to trace the outgoing target address of the pop-up window. We are on a 100mbs switched network (I believe switched but ..). Now imagine my surprise when I could pick up traffic from around 6 other machines, including HTTP, POP, SMTP and all the associated passwords. Some of the machines were geographically close to me in the office but not all. How could this happen on a switched network - has one of the switches fallen over into broadcast mode or something? If so how do I go about determining (remotely) why/how it has fallen over, who else is on the segment, and what other avenues do I have to explore? Thanks in advance Ian
