      That doesn't seem like it would be very hard to crack. The character set is just 16 characters. If the person thought he was being clever, there's could be 10 million people who had the same idea and the cracking software has seen it all before. It's probably not much harder to crack than 12345678.
      I just assume I'm never going to come up with some clever password trick that at least 1 million human beings haven't already thought of.

There he developed an English accent, got a degree (and later a PhD) in cybersecurity to protect his new identity and since he already had close relations with the Web ;) So, this would be the origin story of Dr. Mike Pound

    An update for those of you who are watching this now - I don't know if this wasn't the case back then, but nowadays you use a hash algorithm that is slow by design, like Bcrypt, so that attackers are limited by the speed of the algorithm rather than exclusively by the grade of their hardware.

    150gb password file + hashcat using your video card GPU = any password in minutes. I use the process in the last step to getting all my neighbors wifi passwords, though the possibilities are unlimited. I can do it from anywhere with a $13 wifi card on Amazon.. I felt so gangster when it worked so well right away. Oh wow, I was typing this up before you really got into it. hahah you just explained some hashcat! Nice. To compare, the same process took 3-10 days in 1998. Now it's about 3-10 min for a great password. I was a wireless network engineer.
