- busterarm 11y agoIsn't the point to be able to do these yourself?
- AlyssaRowan 11y agoYes, exactly. In that case, perhaps using the algorithm described in the same place as one may find the reverser's credo: "what one man can invent, another can discover"? (As can women and others, of course! I've always assumed the "man" a forgivable historical artifact there, given the now 110-year gap.) One might tolerate an occasional hint, but please, please, please do not spoil the crackmes and such things. They are for the practice and instruction of those who seek knowledge, not those who want to merely find it. The act of seeking trains the mind in the inference of their creators' intentions and thoughts: a skill that needs to be learned, and I do not think can simply be taught. I am, of course, biased. There is a remnant of elitism, I will admit. Before we had the web, such things used to be swapped via post, and obscure BBSes. It's quite emotional, even, to be reminded some of the old forgotten places still exist. It has been many years. Even... a certain shrine's still running, somehow. Old crackers never die: they just nop! +akr
- foobeef 11y agoWonder what happend to +Mal and others +HCUers now. Probably still in reversing business .. Good ol' days

- 0x0539 11y agoIts a classic alright but being a classic just a warning to everyone some of it does require going back in time a little bit like dealing with a 16bit binary. If this type stuff interests any of you but is too hard, give mine a try ( 0x0539.net ). It is not intended to be a significant challenge, instead all the stages focus on introducing some basic concept related to offensive security. Its mostly aimed at some young teens that have expressed an interest in learning that stuff rather so the target is very introductory. I update the site every so often with new sets of challenges and rotate through former sets if someone requests it. The current one I ran for a bit in 2013 and then brought it back earlier this year and plan to cycle in a new binary exploitation focused one in December.
- busterarm 11y agoI've gotten so far as finding the first secret and turning that into something viewable so I can read the two word question. Not quite sure what to do with the stuff that's left over yet though.
- noobie 11y agoThere are 10 types of people.. ;)
- rhubarbcustard 11y agoI've got past this bit and got the deciphered output but am hopelessly stuck on the next bit. Any clues?
- busterarm 11y agoSure, that gives me an address, but the host isn't reachable. I played around with it and found a login page that might be similar but _no clues_ as to how to gain access. Feel like I'm missing an intermediate step here.
- 0x0539 11y agoOh sorry, that is a side-effect from bringing it back the domain was slightly different. As for the login page, sometimes the way in is not through the front door.
