Subject: Network Configuration Question?
On a corporate machine, I was having trouble removing the TinyBar
scrote-ware that had installed itself surreptitiously onto my machine. 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
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
segment, and what other avenues do I have to explore?
Thanks in advance
