    A new botnet called 'RapperBot' is being used in attacks since mid-June 2022, focusing on brute-forcing its way into Linux SSH servers to establish a foothold on the device.

      Oh my!, it's been A LOT of years since I heard that on Dr. Demento. I think he is still doing a show, he's gotta be up there in years.

        :facepalm: Allowing password authentication in SSH is like securing the vault with a ziptie. Secure key exchange is not that hard. And yes, the number of password-based logon attempts on my server has recently gone from about 10 or 20 a day to 500+. If I used port 22 and didn't use fail2ban, I hate to think how many it would be.
