[GLUG-tech] Re: proxy aware worm/badness using port 443?


Port 443 gets used for ssl. Eg Secure socket layer.. This will be used
by ALL banking sites etc etc as it is safer than http.

I have recently noticed a lot of traffic through our
proxy out to port 443. OK, big deal. Except the traffic
goes to oddball IP addresses that reverse resolve to
dialup pools in Germany and suchlike.

This doesn't sound right -- and I notice one client
machine is making lots of these connections to various
IP addresses, sometimes sucking down large amounts of
data. ATM, it's looking like 200Kbps of port 443
traffic comming in, which is, for us, a *lot*.

Anybody aware of any

- clever new p2p app that goes through proxy servers
using CONNECT on port 443?
- horrible new worm that does this?

Am I going to have to hurt somebody...again?
