"Dude, I'm so sorry to hear that. Glad you got a handle on it before things got out of hand. Double-check those credentials and change 'em ASAP, just in case."
"Yikes, sorry to hear that. I've had a similar experience with a misconfigured AWS instance, it's super easy for hackers to find those exposed servers. Hope you've taken steps to harden your security and change all your passwords"
"Dude, I feel your pain. Had a similar experience last year with my SSH server getting compromised. Make sure to use 2FA and keep those passwords super secure, man."
"Dude, that's crazy how they managed to find your server. Glad you got it patched and secured, but you gotta give props to the hacker for being persistent. Was it a botnet or a targeted attack, btw?"
