Apache on Windows 2K - helllabs?

I was bopping along through my apache access log today and came across a
couple entries I didn't understand. I'm running an Apache server on
Windows 2000, cygwin ssh, typesoft ftp (sometimes) and nothing else I
can think of that it would be possible to connect to. The only unusual
thing about my configuration is that I'm running Apache on 8080. I'm
including the logs so that you can see what I saw. The ranges have been
removed but nothing else has been changed.


Issue:
It shows someone has tried to:
"CONNECT 200.61.10.250:25 HTTP/1.0" 405 315
"GET http://www.helllabs.com.ua/cgi-bin/textenv.pl?8080 HTTP/1.0" 404 302
both followed by:
"\x04\x01" 501 310
Is this a spammer trying to see if I'll let him proxy to some smtp server?

Whatever it is, do I need to worry about it? It wasn't successful was it?


Thanks,
~Mike

Well, that's an attempt to relay spam, as shown by port 25. The 405
indicates that the CONNECT method is disallowed on your server, as you would
hope.

It's somebody attempting to use your proxy to access a cgi-bin env checker
to see if your proxy would connect anonymously or forward identifying
headers. Here's what it returns for me:

[demonstrating as it does that my ISP has a transparent inline cache/proxy
which adds a X-Forwarded-For: header to my request.] The 404 means your
proxy won't forward requests for sites it doesn't host locally, which is
also what you'd hope for.

That's an attempt to see if there's a socks v4 proxy running. That's just
plain daft to send to a webserver.

> Is this a spammer trying to see if I'll let him proxy to some smtp server?

Yep. Maybe several of them, or some combination of spammers and people
looking to do a spot of anonymous websurfing/hacking.

> Whatever it is, do I need to worry about it? It wasn't successful was it?

Nope, from what I see you're blocking it. Is it possible your proxy was
open when you first put it up on the net, and that your IP got onto a few of
the public proxy lists somehow? If that was the case, it'll presumably drop
off in time since it's secure now. If not, it's just background noise.

From "Helllab's" website:

Is it legal to use someone's proxy server?

"Yes, absolutely! When some person installs proxy server software he has
an option, whether it should be public accessible server or not
(password protected). In the first case proxy server is the public one
and you can use it for your purposes. If someone (your ISP or owner of
the proxy server) tells you that you have misused proxy server, point
him out that there were no password protection, therefore you have used
public proxy and did not violate any rules."


So, I guess, by this definition, I can scan the Internet looking for
default accounts left open w/out passwords- and if I do get it, too bad,
right??

;p
