This is normal behavior for bug hunters and I don't think they're doing it because 'it's cool". They do this for a living.
Which one do you prefer?
While I enjoyed the article that GP referenced and agreed with most thing I thought the “hacking bad” take was a bit off.
In my neighborhood, "security researchers" can often be seen checking houses for vulnerabilities. During the day, it's usually a woman or a kid with a clipboard who knocks on front doors, checks for cameras, tests if the front door is locked, etc. I'm told they work with crews of men who will come back later to do a more thorough investigation when everyone is gone so as not to bother the homeowner.
Every night, there are other "security researchers" who test all the doors of all the cars parked on the street and in driveways. If you leave your car door unlocked just once, you'll be informed about it the next morning!
It's really something to live in these times!
"What happened to the good old days when we could all leave our cars and homes unlocked.."
Yeah no.
That is actually a really good question you should be asking. Also when it comes to computers.
Half of that post is unhinged nonsense. "Hacking is Cool" is listed right after a rant about pentesting being dumb because your software should just be designed to be secure.
Ah yes, the classic surprise pentest by unappointed security researchers. I too, as the good samaritan that I am, like to stroll through my neighborhood and give all the cars and bikes I encounter a quick pentest, purely for the benefits of the owners of course.
I remember there was an article "the six dumbest ideas in computer security" on HN a while ago, one of those was the mindset that "hacking is cool". I'm reminded a bit of this here.
