Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

Does the attack succeed? Never happened to me. You see bot trying, but really never seen succeeding irl. How is it configured?
Do you have also a rdp honeypot by chance? Do you see different rates of attack? Honestly curious.
I don't have any windows licenses around, otherwise, it would have been an interesting test
Also, antivirus is the wrong idea there. What you'd want is an intrusion detection and/or integrity checking system.
And disable password authentication as first step
It's configured to allow requests from connections using common default passwords. If it wasn't a honeypot the requests would succeed. I don't currently run an rdp honeypot but I did a few years back, iirc the rates were about the same with rdp being a little bit less. Which as I say, comes down to configuration and usage. If you misconfigure Linux you will get malware, same as Windows.
Ok, than the experiment you are doing is just to check how many attacks you can get over a certain time... It is not really representative of a common use case. And again, this is not a virus. It is a successful attack from a bot on a purposely misconfigured service exposed to the internet. An antivirus is not needed. What is needed is basic configuration. An antivirus cannot help there
Okay if we are taking the definition of a virus to be something that a person must download and execute, what about malicious javascript/python packages? They often target production systems running Linux and infection is caused by user error rather than misconfiguration.
I use python professionaly. Never seen a real successful supply chain attack on libraries used by "normal" people. There was recently a supply chain attack to pytorch, that I remember, but it was solved within few hours.
It is not a real risk for non developers. It is a risk, but veeery low, miles lower than pdf.exe.
Just check this stat for ransomwares taken as an example of viruses: https://www.statista.com/statistics/701020/major-operating-systems-targeted-by-ransomware/
Windows server is ~20% of server market. Still it is there second, with in practice no GNU/linux (80% of server market). This is why people do not really worry much, the risk exists, but it is minimal for well configured system compared to competition, even where competitors are a niche and Linux machines are the main target.
On windows, an antivirus is not a bad idea... On Linux, a firewall and basic care are usually sufficient
