Yesterday I could not fall asleep immediately so I decided to test some applications which are by default included in Windows. I had a look at the Windows games (Freecell, Hearts, Minesweeper, Pinball and so on) and during fooling around a feature namely saving game scores of Spider Solitaire sparked my interest in having a deeper look at it.
You can not choose the file where to save the highscore in and you overwrite the stored highscore everytime you save another game so I started Filemon and found the file `spider.sav' which is located at "%USERPROFILE%\Own Files".

Yesterday I came across an interesting blog about "IDA, decompilation, programming, binary program analysis and information security". Ilfak Guilfanov, the blog author, discusses a lot of IDA related topics like debugger hiding tricks, TLS callbacks and handy IDA plugins (source code included).

Recently there was a CrackMe-Contest at buha.info (A German security community) . It consisted of ten different levels sorted by difficulty. I think it was a good idea to involve various programming languages for example C/++, Java, VB and C# in the contest because so everyone had to concern himself with a language he maybe does not like/use.

Last night, I uploaded all received solutions (keygens, keygen-patches, source codes, algos, howtos etc.) for the different levels to the CrackMe-Contest site. So all crackmes (source code included) are well documented and helpful for training purposes. Especially crackme #1 and #2 from nait (level 9 and 10 of the contest) and the great step by step guidances (by CDW and nait) to understand and solve the crackmes are worth a view.

An ExploitMe-Contest and a sort of HackMe-Contest will take place soon so stay tuned..
