Fennec.ws network traffic

Recommended Posts

Hi

Does anyone know why arma2oaserver.exe want to continuously send data to 208.53.128.27.. ie fennec.ws. ?? The data usage sits at about 88k/sec.

That i,s when I start the server and resource monitor, tick server.exe, and watch the network traffic, I can see packets going to various address but this one stands out as a bandwidth hog.

just looks sus...

Thanks....

Did you do an AV/malware check? Maybe your server got infected.

from where you obtained the arma2oaserver.exe (just for sure) ?

using any "3rd" party tools from unknown sources ?

We done a full virus scan and found nothing, the server is newly built and only been running for 5 days in a new data centre.

All arma files obtained from sprocket. Fire Daemon and Rcon. We first suspected Rcon and shut it down but the problem persisted. As Gonk said its coming from or directed at the arma2oaserver.exe..

We ip blocked it and don't have any further issues. but still doing a google search and trace route on it finds some very shady info.

I was using the Linux server from the sticky with the rest of the required content downloaded via Steam (using a VM). A friend of mine was toying with mission editing and had access to the machine but he hasn't logged in for a month. According to ntop it was sending stuff over port 21.

I have also notice more and more ip's having only Outbound network traffic from arma2oaserver.exe. They usually sit at about 50-70 k/sec. With no one connected to the game server... ip's like.. 109.169.x.x , 89.238.x.x, 216.246.x.x. Is there a security hole in this exe that ppl are exploiting ???

Where are you renting your server from? Or are you running the server on your PC?

we have our own server located at a Data Centre... (Co-location). We are only running on instance of amra2oaserver.exe. Just curious wheter other server admins are see this kind of activity.

Could this be related?

Either a mission (a picture or html file) or the server exe infected by the malware as it looks like.

I wasn't able to get to the source though.

I see similar behavior but connecting to chi.xfactorservers.com (88.198.6.24). No one on the server and the UDP traffic is from the arma2oaserver.exe. I disabled Battleye just to check, but the traffic still appears.

Confirmed the MD5 hash is correct, so don't think malware or a virus is at play.

I then added a firewall rule to block that IP address then restarted the arma2oaserver.exe. It tried to connect to the same address, but couldn't and eventually got to 0 bytes being sent. Then I restarted arma2oaserver.exe again and this time it connected to 66.150.214.8 (dallas-vetrilo.nfoservers.com). I repeated the same, blocking that IP and then restarted. So far it hasn't reconnected to anything with that high packet count.

Both xfactorservers.com and nfoservers.com are game server hosting companies, but can't see a reason why arma2oaserver.exe starts immediately sending 25k+ traffic continually to it ... with no traffic back that I can see.

Yep.those two are also on the block list. Saw them a couple of days ago. There must be away to see what is being sent.

Could you describe briefly how you do check the outgoing traffic,

so that others can check too that we get more data here. Thanks!

Most basic way to check network traffic within windows is to start Task Manager:

'Performance' Tab. At the bottom click 'Resource Monitor'.

Then 'Network' Tab

Install Wireshark and capture the traffic. I will attempt that today but, as I pointed out above, after I temporarily blocked the IP address in my firewall rules the traffic stopped even after I removed the rules.

rgr.. let us know what you find... I am plugging holes left and right...

174.x.x.x popped up today sucking 100k/sec. Will have a closer look on the weekend...

I came back this morning to find a new UDP session against 85.17.96.111 (hosted-by.leaseweb.com). I have checked with Wireshark and it's just ICMP (ping) traffic. There's no data in the packets I'm seeing on my server.

It's now really up to BIS to explain to us why the server is doing this as I really don't think it's a hack of any kind. I suspect it's related to the Gamespy support.

Have you tried the beta server yet ? this non-stop pinging response is eating into out data limit.
