Basement dwelling geek probably using freeware like Wireshark to sniff data packets is not hacking. This guy is a fantasist attention seeker, not some kind of James Bond super Villain.
That ridiculous beard will be a useful recognition aid for flight crew in future, the Commander will be able to deny boarding before he gets past check-in.
Exactly. Every intrusion I've encountered has merely been some "hacker" detecting the presence of a system. The moment they start trying anything the IP address is blocked, so brute force password efforts are eliminated.
On the systems I work even unumeration efforts result in an IP block.
Some of these "hackers" may get a thrill from seeing that they have access to a minframe logon screen but their efforts end their. All that they have done i gain access to a port and an IP address which are publicly available but not publicised. That's not hacking, and systems are designed to flick these flies of our butts with a judicious swish of the tail.
That said, I have to fear those who create tools in private.
