Not at all. You leave a ssh port open, you don’t get a virus. Try it. Set up a raspberry pi, install ssh and leave the port open in your firewall. It is much less risky than exposing rdp (the most comparable windows protocol) on windows for instance.

It is a security risk, but absolutely not comparable of installing pdf.exe.

As said, try it now and tell me how it goes.

Glad you asked, I run a ssh honeypot and get multiple connections adding ssh keys, trying to run lockr, downloading shit every day.

2023-09-16T09:09:48+0000 [SSHChannel session (1) on SSHService b’ssh-connection’ on HoneyPotSSHTransport,14737,61.222.241.108] Command found: echo ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEArDp4cun2lhr4KUhBGE7VvAcwdli2a8dbnrTOrbMz1+5O73fcBOx8NVbUT0bUanUV9tJ2/9p7+vD0EpZ3Tz/+0kX34uAx1RV/75GVOmNx+9EuWOnvNoaJe0QXxziIg9eLBHpgLMuakb5+BgTFB+rKJAw9u9FSTDengvS8hX1kNFS4Mjux0hJOK8rvcEmPecjdySYMb66nylAKGwCEE6WEQHmd1mUPgHwGQ0hWCwsQk13yCGPK5w6hYp5zYkFnvlC8hGmd4Ww+u97k6pfTGTUbJk14ujvcD9iUKQTTWYYjIIu5PmUux5bsZ0R4WFwdIe6+i6rBLAsPKgAySVKPRK+oRw== mdrfckr >> .ssh/authorized_keys

  Does the attack succeed? Never happened to me. You see bot trying, but really never seen succeeding irl. How is it configured?

    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 to check how many attacks you can get over time… It is not really representative of a common use case. And again, this is not a virus. It is an successful attack from on a purposely misconfigured internet service. An antivirus is not needed. What is needed is basic configuration

  Running a honey pot for SSH and sharing logs only proves that people try to attack you, it does not really tell if SSH as such is vulnerable or not. It is a honey pot, people gaining access if the whole point.
  
  Having a locked down but exposed SSH access is something else.

    You’re missing my point, a virus doesn’t have to infiltrate a completely secure system. It can come through you accidentally leaving your ssh insecure or any other service.

    I get that a malware can get inside the worlds most secure system, if for example a user lets it in. What I am saying is that showing a honey pot in response to “ssh is more secure than a software that runs code without you giving consent and without your knowledge” not say anything, except what happens if someone gets in.
