Firewall Blackjack request on port 1025

[Fraha]

Hi all!

My firewall (Norman) keeps asking for internet access for port 1025 for svchost.exe

I can't determen wich service this is. It tells me 'system' that's all.
But it keeps wanting to connect to another ip address.

TDS cannot find anything wrong, I can only see it's there in port explorer (great proggie!)

What can I do?

Frans

Here's my hijackthis log. Can somebody check this for me? I think I saw a switch point at the end!

which IP number is it asking to connect to

most outgoing svchost "system" connections are legitimate" but if we have the Ip number we can check

[Pieter_Arntz]

Hi Fraha,

Your log is pretty clean , so I will give you this link and move your thread to the firewall forum.

[dvk01]

providing it's outgoing I let it go but I have all incoming blocked so \I don't get bothered with alerts, but I use kerio as I find it more configureable for me

No doubt one of the firewall experts will be able to advise better

[Fraha]

OK, thanks for the reply,

I'll wait for other reactions then.

Can you provide any more detail on the type of communication from your logs? (Protocol, direction, source port, destination port, destination IP - complete log entries would help, just xxx out your public IP)

Thanks for all the respons. It seems solved for now. If this returns I'll be back!

Hi Guys,

I am having same problems. Svchost.exe accepts connection from differnet ips. Everytime i run tcpview, i see port 1025 is connected to some ip either on my cable network or some from internet...different countries..

I tried all sort of tricks, reading packets, watching port etc...i dont know, whats happening there..i can block the port but i am more curious to know whats happening on there..


Looking forward for somehelp

[edit] -> its a TCP connection and connected ip is different everytime

Thanks,

Hi,

Well i kept investigation on port 1025 connection. And i found remote computer connects to my pc using WBEM, and it creates some files under C:\WINDOWS\System32\WBEM\Repository\FS

So WIM or WBEM can be source of big exploit...as WIM gives entire details of workstation along with remote control...

Investigating further on it......


Regards,

[The_ALL]

i want to understand what you want know about 1025 port.

as i posted, the link explane how work a network behind a router or modem or proxy.
if the nat is active or you have a server browser,the port from 1025 to 5000 must be open, or if these ports are not open, external client computers are not able to access the Web sites or other application you run.

if you want more security,restrict incoming traffic on your firewall by Internet protocol (IP) address instead of by port.For example, create a filter that only allows traffic from the proxy server through the perimeter network's internal firewall, on any port in the 1025 to 5000 range,so this filter allows incoming traffic on any port that has a source address that matches the proxy server's address, and blocks all other traffic.

Are you running a firewall?

Could you provide full details of the connections: protocol, source and destination IP/ports. Just xxx out your public IP.

Which OS and services are you running?

WIM? Did you mean WMI - Windows Management Instrumentation
WBEM - Web Based Enterprise Management

Regards,

CrazyM

[asad]

I am running Windows XP Professional.

Protocol : TCP
PORT: 1025

IP: changes every time

I have zone alarm as personal firewall but it doesnt detect.


SVCHOST.exe accepts connection on port 1025. I am not behind any firewall and i use dsl here. Since there could be many instances of svchost.exe because it is used by os for internet connection etc.



>>WIM? Did you mean WMI - Windows Management Instrumentation
>>WBEM - Web Based Enterprise Management

Yes, this is what i saw in file monitor. I downloaded a file system monitor from sysinternals and ran. I found the svchost.exe which has accepted connection on 1025 is reading and writing files in C:\WINDOWS\System32\WBEM\Repository\FS

One file which was written on every session grown to 5 MB+, file is OBJECTS.DATA.

Now i have disabled WIM service from services.msc and i dont see any such connection on 1025.

It seems to be resolved but i am still curious to know, what was happening there..if i didnt stop, what would have been possible..etc..

But i guess, its good start point to further investigate on this port 1025 thingy...

Believe me WIM and WBEM can be used to do anything on a remote system as per my knowledge.

cheers,
A

I see about the same thing, and it started recently, within the last week or so.
I see protocols 1025, 1026, and 1027 also associated is 3127 and 6129.
I use Zone Alarm Pro on my own machine, so I just blocked the three lower ports.
I harvisted the following list from the Kiwi Syslog deamon that I have logging traffic through my Linksys gateway router.

The 68.94.xxx.xxx are within Cox.net, my cable provider.

I checked further and concluded that this is a fairly wide-spread and rapidly spreading trojan virus:

I am doing a current scan to see if any attacks actually penitrated my machine.

Hi,

As i mentioned in my last post that svchost.exe on port 1025, let remote computer access through WBEM or WIM.

But i lately found, it doesnt use WBEM or WIM all time. This time it was using \WINDOWS\system32\modemui.dll

I am really serious now and more curious to know, what does it do.

As jim@knock.com just mentioned, it could be trojen. So it makes our concerns more serious.

Guys, lets find the exact reason with soln.

Regards,
Abdul

SVCHOST.exe accepts connection on port 1025. I am not behind any firewall and i use dsl here. Since there could be many instances of svchost.exe because it is used by os for internet connection etc." }-

You mention "I have zone alarm as personal firewall but it doesnt detect", then say "I am not behind any firewall and i use dsl here".

Are you currently running a firewall or not?
Are you currently running any proxy or other web filtering utilities?

You mention protocol TCP and port 1025, but in order to clarify what type of connections may be happening we need more details. Are these in fact remote systems connecting to your system, or connections initiated by your sytem? Protocol, direction, local address (xxx out your public IP), local port, remote address, remote port.

Edit: svchost.exe may need some outbound access, but you should not be allowing unsolicited inbound connections.
