I went from John the Ripper to L0phtCrack to Hash Cat. Now I want a Quantum computer because for some type of passwords even running Hash Cat on a big GPU farm is too slow because of hashing algorithms.

Bad news is: a quantum computer will not crack hashes faster.

It would reduce the output space of a cryptographic hash by its square root. That would help speed up attacks would it not?

I recall running this on a dual core Celron (BP6 dual socket motherboard) over-clocked back in the day to get 1Ghz `testing` power. Fun times.

Ah I remember that setup. The fact that 'normal' people could actually afford a 1Ghz computer was mind blowing.

I remember that motherboard :-). Cheapest dual socket setup you could get.

Human, I'm 28, been in InfoSec for ~10 years. Granted, I was lucky enough to be interested in and peruse this as a professional branch when I graduated college in 2016. I am also an adjunct professor at my local university, where I make it a salient point to remind my students of the history of hacking. We talk about this still. I also start every semester off with the opening scene of Hackers - the best hacking movi…

Lacks the soundtrack. I always work to music to help focus.

I used it in ~ 1999-2000 to check password strength in the company I worked for; it was running for 1 minute, for any password that was recovered the owner got a notice to change it immediately. Initially 50% of the passwords were the username and more than 50% were up tp 5 characters long. At that time an 8 char min length was "safe enough" for a company that had no sensitive data other than the payroll.

I was going to object to your "under 30" quip, then realized I haven't been under 30 for quite a while. Oops.

I'm in the same boat, and it's really amazing how quickly things change. I was explaining to a coworker the other day how much more optimistic we were in the 90s, and when he casually mentioned that he was born in 2000, I suddenly felt really old.

The number of candles on my birthday cake seems to change the fastest. I ask for hexadecimal whenever possible.

I got expelled from high school because of this program. I'm a millionaire now though so shrug

I was a hair's breadth away from expulsion too - exfiltrated .sam files from a PC in the library on a 3.5" floppy. Seems to be quite common experience judging by this thread.

Why did we all get caught? Smart enough to figure that out in your teens, dumb enough to think you can get away with it...

In my case I was operating with a dumbass friend who left a "calling card" on one of the compromised machines.

They tried to expel me for this (among other) reason(s) too, though the Vice Principal went to bat for me and instead I was banned from using any computers on school property for the last couple years of high school instead.

Very similar experience - in the end no police, and I just had to stay back and write a long essay on why hacking is wrong (pretty sure I was an edgelord about it and wrote something nuanced about white-hatting...)
