Serious Discussion Is this a malicious domain?

[ByteSentinel]

Hi all,
I like playing windows games on Linux and one of the game I'm playing is contacting the domain below that is flagged by Controld AI Malware filter. I put that domain into VirusTotal and none of the AVs is flagging it, is this a false positive or should I be worry?

Spoiler: Domain

uc-jw.ucloud.com.cn.ucnaming[.]com

My KES detects it as untrusted because a problem with certificate, ignoring the warning:

ERROR: ACCESS DENIED​

1. The actual owning domain is ucnaming.com
2. For the domain names ucloud.com, ucloud.com.cn, and ucnaming.com, only the last returns information about dates and registrant (Chinese).
3. Those domains don't have an entity main website

I would treat this as suspicious and stop playing the game until things become clearer. If it's not a network game, maybe just Firewall the game altogether to keep playing. Not having a valid HTTPS certificate definitely shows a lack of effort because the certificate is free.

Should I go ahead and re-image my laptop just in case? I stopped playing that game since it's a gacha game and requires network.

Does not look good. First run KVRT & ESET online scanner and see what it turns up. If in doubt after that re-image.

I'm using Fedora secureblue so I can't run those scanners unfortunately. I've gone and re-imaged my laptop and kept an eye on my ControlD log to make it's nothing serious

LOL mate if your running Fedora your 99% probably not going to get rinsed or pwned by some random malicious Chinese game or website.

Unless you work for the government and targeted in the attack your clean. Fedora is not the target audience for 99.999999% of hacks/attacks.

Or unless you work in cybersecurity, where security testing is a sport.

Just for amusement, a couple of years ago I erected a domain boastfully named 'nohackershere.com' advertising a made up cybersecurity firm using Godaddy do-it-yourself tools. It got wiped within a month. The pretty stock photo CSO wasn't spared

Even then your not going to get pwned. Fedora is about as interesting as Nana's knitting.

What do you think about Ubuntu? It is more popular among new Linux users, like Mint. Do you think those 2 are more attractive to hackers ? I learned OpenBSD first. And Ubuntu was the first Linux I stayed with.
