| | Hadn't noticed monthly membership had rocketed so much. Good work! |
|
 |
| | I'm a member of the PSP homebrew scene, some of the PSP's encryption is quite hardcore, so OSIX has come up in conversation a few times, hopefully a percentage of those new memberships come from the PSP Community. |
|
 |
| | Maybe i should write a PSP Encryption article, not sure how much interest it would be to the general populous though... |
|
 |
| | I used to follow the community so would be interested in this. |
|
 |
| Really, why did you stop? If i where to write an article on the PSP, it would probably be around NIDS (Can be thought of as API's). There are still a lot of unknowns, some of the encryption algorithms and the precise method of executable signing specifically.
Writing software for the PSP is still not for the faint of heart either, compiling the toolchain and environment takes all night! Then there is very little in the way of support (Obviously) the result is, a "hacky" feel to each piece of source you see. |

 |
| I'd certainly give it a read MaxMouse.
Also, I clicked on the members link(up in the article there) and down the bottom where there's the list of the number of people that joined each month, I found this:
[...]
February 2004 165
January 2004 187
December 2003 240
September 2003 1
May 1903 1
I'd never actually noticed that before, lol. |
|
 |
| | I mostly stopped when I entirely discounted it as a development platform (based on the homebrew I saw), and DA pretty much had the other side of things taken care of. |
|
 |
| Dom, The funniest part is, for an "Open Source" community, there is a whole lot of homebrew and indeed, firmware/hacks etc that are closed source lol
Well, when i get some time I'll do a snippet on PSP-NIDS, what they are, how to crack them, and the issues encountered when doing so :)
PS: what's with the May 1903 thing?! lol |
|
 |
| | Guessed who it was on my first try, it's think12. He likes to play - I'll give you a prize if you figure out what's significant about that date/time. |

7th May, 1903 at 03:25:01PM
1903+5+7+15+25+1 = 1956
1903+5+7+3+25+1 = 3874
07 05 19 03 15 25 01 (All prime numbers except 15 and 25) ...
Google doesn't say much...
I dunno.. clue? |
|
 |
| | You could try looking up the UNIX timestamp for that time. |
|
 |
| | -2103438899 - Errm... lol... |
|
 |
| | Maybe it's significant in some other base, or representation... and maybe it's something significant, but obviously modified? |
|
 |
| | it could be phone number, in Bexar, Texas? Although I thought it would be Canadian though judging by think12's location |
|
 |
| | maybe even the IP 125.95.238.51 |
|
 |
| | Ha, nice idea with the IP address. It could also be worth looking at what the IP would be when the timestamp's negative? I'm guessing you'd want one .ca or .uk. |

neither are registered on DNS and and TCP scanning hasn't shown up anything yet, this feels like a hackthissite challenge |

haven't done a port scan but suspect IP is the wrong tree to be barking up |
|
 |
| | I give up, spill the beans Dom. |
|
 |
| | Ha! It's not significant at all, as far as I know. I was looking into it myself though, and wanted to see if people would go down the same routes I did, or come up with something new. The best I was hoping to find out myself was a real date with a few figures added, but I didn't even get that. Who randomly puts in a date like that? Did he just make it a few months before Sep 2003, and then figure, hell, I'll go a century earlier? |
|
 |
| | However, three points to you, MaxMouse, and five to you, CodeX. |
|
 |
| woot :D
Maybe the date was made using a rough calculation e.g.
s = 1
m = 60 s
h = 60 m
da = 24 h
mo = 30 da
ye = 12 mo
so the date was intended to be around 1970-01-01 00:00:00 - 67-7-15 8:34:59 or something like that, however just doing it because you can sounds perfectly reasonable too and I'm happy believing that |
|
 |
| | lulz we where had! - I don't see a reason behind it, but it does seem a rather random thing to use... anyone asked think12 about it? |
|
 |
| I've got it, its a one time pad! The cyphertext is:
0xffffffff82a011cd (uint64_t of timestamp)
and the key is
0xa79a9b90c1807885
when these two are combined you get
0x5865646f43206948 which on a big endian platform forms the bytes like so in the memory:
48 69 20 43 6f 64 65 58
interpreted as ascii this produces:
Hi CodeX
:D solved, not exactly sure what generated the key but its obviously the solution, at a rough guess the key was generated by:
(2^8)*(5^3)*11*303119*113190023
something else was that I probably wasn't even using the alias CodeX when think12 joined so that makes another mystery :O

 |
| | All i can say is WTF CodeX?! Seriously... WTF?! and your on level 8? |
|
 |
| | I misplaced my hint for the level quite a while ago and being as persistent as I am gave up and that was quite a while ago |
