The closest I've had to an incident (that I know of) is when one of my WordPress installations was compromised for shady SEO purposes. I discovered this when I analyzed my web logs and realized that the prevailing search terms that were driving traffic to my site were all pharma-spam terms.
HACKER was the first game I was able to get in my hands after getting my Amiga 1000 in Oct 1985. The UPS guy had delivered it and left it in a shed in our yard - it had been there for a few days before I found it, I recall.
Technically yes, but nothing bad really came of it. The SSH server on my computer is exposed to the internet. I have an account named "test" with a password of "test" that I use to serve files via FTP to my Wii, as well as run some maintenance bots on Wikia . Some bot from China guessed the password and kept trying to login. Fortunately I had set the shell to falselogin and it didn't have any admin rights, so there wasn't much it could have done. I changed my configuration to deny SSH login to that account anyway.
I had a couple of good run-ins. One guy was using the Sub7 Trojan to control my system. That was a fun time, didn't do much, just a script kiddie having fun. Eventually they turned on Matrix chat and was chatting with me about how 'stupid' I was blah blah. I was 12 at the time. I then learned how to use Sub7… … and I will stop talking about that there LOL
After that experience, my local network has been locked down so tight. I have had a few brute force attempts but no Mongolians breaking down my walls!
A friend of mine who isn't the brightest bulb once unknowingly donated a virus to me. I got a bit suspicious when a computer with a week-old Windows installation that had never been connected to the internet started popping up saying I had 9000+ compromised files, and spontaneously opening IE windows to generic adult websites.
I manually dialed in the QuantumLink number in the terminal package for my C64′s modem (see other thread on first modems) and instead of getting the usual fol-de-rol that comes with dialing in I got the LOGIN: prompt.
I tried a few things, realized I wasn't Matthew Broderick and my '64 wasn't Joshua, and there was no getting past that prompt so I went back to playing games.
