Aside from being a certified system engineer back in the dark ages I had my forum attacked, the attacks launched from two outlaw forums. I had to come up to speed in a hurry on some things. There are sites that people use to develop and exchange code just to stir crap mostly although some might be aiming at profit. Programs to be bought very inexpensively too. Not to mention governments all over the world hacking and hammering away. I suspect the US of being at least as big a culprit as any, maybe the biggest. Got to play the game today.
Anyway, anyone is open to attack including just blast attacks to see what the attacker gets. The odds of successful attacks goes up the tighter your security gets but it matters little if the average time to break your security is a few hundred years and somebody stumbles in taking only days. It can happen. Government computers being hacked should tell us there is no such thing as perfect security. Somebody can daisy chain a bunch of lower end computers and come up with a killer machine to hammer on security too. A few years back china had the fastest supercomputer in the world. They created it by using hundreds of comparatively slow PC CPU's daisy chained together and working in parallel. Another issue, some malware uses your computer and internet access. This software can daisy chain hundreds or thousands of computers together.
My attackers and others that wanted to play anonymous games? It never took me as long as three hours to track them to their homes, where they lived, phone numbers, where they worked, I stopped there and contacted them with polite e-mails suggesting we should meet and talk. I asked would they prefer we meet at their home(information given) or their place of work(information given). I destroyed the two websites that attacked me. One owner's legitimate business had government contracts. I inquired how long the owner thought his government contracts would last when he faced a handful of felonies?
I was green as a gourd until I was attacked. Forty or fifty hours of work and research was all the time it took for me to be able to block and return attacks. Also, there was a cash bounty for my personal information on a site that had dozens or hundreds of hackers on it. I visited that site daily as an anonymous visitor for a few months to check what they were up to. They could see the B class license that was my last bounce, still a long ways from me!
Just a little discourse for those that think they can't be hacked. Hackers are out there, with as many hacking away as are out there, some as a full time hobby for years, skill or just one of the blunt force type attacks may nail you.
When it comes to cyber security over 95% of us are woefully ignorant, most that aren't are working in the field. Making a living at it is the only way to stay fairly current.
