Lots of RTP detections followed by partial network outage

Hello everyone. This is less of a malware removal help request, and more of a question.

I was hit with something strange an hour ago. MalwareBytes started reporting a ton of "RTP detections" from chrome.exe, all with the same IP, (I don't believe I was actively browsing at the time.)

Additionally, the first "RTP detection" logged is categorized as "Trojan" under the "Event details" column, while all subsequent ones are categorized as "Malware." All "Actions" were "Blocked website."

There were two RTP detections logged per minute between 15:05 and 15:21. At some point during that time, my Internet connectivity went down, but in an unusual way. I was connected to an online multiplayer game, but it kept working without a hitch — perhaps because it was using some direct IP connection instead of relying on DNS? But everything else stopped working. I couldn't load websites, even my router admin interface on my local network, and the system tray's network icon displayed as the little globe that indicates no connectivity (as opposed to the outline of a screen with a cable next to it) Out of curiosity, I tried the Windows troubleshooter, and the only thing it could suggest was to perform a network reset, which I didn't do.

Here are some bits from the Windows Event Viewer that may be relevant:

  • (15:06:00) DNS Client Events: Name resolution for the name telemetry.malwarebytes.com timed out after none of the configured DNS servers responded
  • (15:06:02) Tcpip: TCP/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint. This error typically occurs when outgoing connections are opened and closed at a high rate, causing all available local ports to be used and forcing TCP/IP to reuse a local port for an outgoing connection. (...)
  • (15:16:45) DNS Client Events: Name resolution for the name heartbeat.dm.origin.com timed out after none of the configured DNS servers responded.
  • (15:16:48) AFD: Closing a TCP socket with local port number 50767 in process 21288 is taking longer than expected. The local port number may not be available until the close operation is completed. This happens typically due to misbehaving network drivers

After rebooting my computer, everything was back to normal. There have been no further "RTP detection" events logged in Malwarebytes.

Malwarebytes scans have not reported anything detected so far, and neither has MSERT.exe.

Did I stumble onto a MB bug that caused this weird issue? Should I be worried of an actual infection on my computer?

Let me know if I can provide logs or any additional details regarding this.

Cross-checked with my browser history and it seems very likely that it's this web page (opened at 15:06, but left in the background) that was responsible: https://gamebanana.com/members/1238771

Warnings from Malwarebytes about are popping up again while I visit it, despite adblockers being enabled. Maybe there's a malicious ad somewhere.

So that seems most likely to be the root cause, but as to how and why it could bring my internet connectivity down... hopefully the logs will help someone shine light on what happened?

Were they incoming or outgoing?

The detections were outgoing. I was able to reproduce them by visiting the webpage I mentioned in my previous post, so the source is known. What I couldn't reproduce was my Internet connectivity going down after a while; because there's a possibility this might have been a Malwarebytes bug, I figured posting the logs would be helpful.

(I've hit strange MB bugs before, like the one that caused my PC to BSOD if a RTSP stream was accessed over LAN...! 😀)

I am not getting blocks on that page.

I'm not getting them anymore either, which is why I'm inclined to think it was an ad that was connecting to a blacklisted IP — failing, and trying over and over. Further searches have led me to a forum post that mentions this specific IP related to ads as well. This page claims there is a link between the IP and the gamebanana domain name as well.

I will run this tool and create a thread just in case, though—better safe than sorry! (I just want to write everything down in case that helps someone later down the line...)

We are the owner of the IP. It is a simple file caching server, identical to several others, that just serves JS and CSS files for a website. That is its only function. I have run a rootkit scanner on the server to check for trojans, and I could not find any. The server is relatively new, we set it up a couple of month ago. All I can think of is the IP's previous owner was malicious.

If this issue keeps occurring, we are open to reloading the OS and software on the server to ensure everything is clean.
