This is a challenge for those who like unpacking .NET and It's protected with the latest version of Reactor Enjoy it but remember that a tutor is required in case you manage to unpack it. UnpackMe.rar

After lARP v2.0 lite which was step-in level, here is an unpackme protected by lARP v2.0 Standard Ed. Dump and remove stub section. It would be great if you shared your remarks and the way how you did it by pm please. Don't hesitate to pm me for this one O, and the original unpackme doesn't run on win9x, hence the lARPed file doesn't either lena151. lARP_v2.0_Standard_Ed._UnpackMe.rar

Unpacked, but still not cracked The file has been succesfully unpacked by sdy100 Check his unpacked attachment abit further down. Waiting for a full explanation. Did you run into any problems? Correct Key solved by Till.ch Correct key is: correctkeyisthishao Information I just recently found my passion for protection coding along with trying to break it. I've used a opensource packer and made some heavy modifications to it, also added loads of anti-codes. I've had no success in getting out the correct key which you are supposed to type in, neither been able to unpack it. Allthough, i am a terrible reverser, i would like to get a 2nd opinion about this protectio…

This is a crackme I made 4 months ago and it has not been solved yet. Target: VistaSidebarGadgetCrackme by TiGa on www.crackmes.de Format: Windows Vista Sidebar Gadget (.gadget) Work to do: Find out what is a .gadget Remove the nags Activate the backdoor Turn the crackme into a keygen in .gadget format Write a solution Optional Work to do: Write a keygen in a "traditional" programming language (.exe) It doesn't absolutely require Vista to solve it but it helps a lot. Prepare yourself to be amazed by M$'s new "proprietary" file format. TiGa VistaSidebarGadgetCrackme.by.TiGa.zip

Actually it's no serious .net protector at all. But as I had a look, why not posting it. You can take it as an easy Fix-Teh-Dump-Cookie. There was no open download link for the .net version of PC Guard. And now I know why.. some mins ago even my grandma successfully unpacked it. There's indeed lots of encryption, antis, checks - nevertheless all in vain for .NET... they take money for nothing.. :/ The app can be run for 20 times only.. with random demo messages. Hint: 8 values have to be fixed in the dump (after some cutting). UnpackMe_PCG_502.rar

Packed by [Mine noname packer] Build Today, 02:13:02 GMT +2. Packed file: Resource Hacker (If wouldn't be so lazy, i would make programm, which shows only MSG Box).

Hey Here's my very first keygenme, thought it was time for such thing. I'm not going to say that much about it, it's your job to find out. It uses quite a lot antidebug, so if you find it crashing even outside a debugger or you are ABSOLUTELY sure antidebug cought you falsely, write it here and I *might* remove some of the antidebug... I'm pretty sure it doesn't run on < NT system, but I can't say for sure. Worth a try I guess You might experience false positives by AVs, I tested it at virustotal.com (go ahead and check for yourself) and only 4 of them reported it as 'malicious' or trojan. This is due to the packer used, so don't worry and get a proper AV if yo…

Hello all i leave here a dll file packed.I leave it as a challenge for experts.Cya and happy cracking test.rar

My very first Keygenme made in delphi 7 (I know, I should learn some more ASM). Just make a keygen for it. Also, it's packed with UPX 2.03w but with nothing else, so unpacking should be easy Post keygen when you're done. KeyGenMe_byAnte0.rar

try this, it's for beginners, no special knowledge required. do not patch, make a keygen cm260807.zip

This is a pretty easy KeyMe. Beginner-Intermediate range. The algo isnt very big at all but there are a few tricks. The goal of this KeyMe is for those who are pretty new to RE. It gives you a few curve balls that make it tougher. Don't worry though, the code is in assembly and is quite easy to read. Pay attention to the API's that are called. As well as the strings available to you. There is no encryption, packer, or protectors used. It's a whole 4kb so you dont have much to sort through. I hope you enjoy the keyme. Download: (UPDATED) http://rapidshare.com/files/69688808/KeyMeAsm1_FINAL.zip Patching isnt allowed. Once you complete it, leave the details for othe…

RLPack 1.19 [NT only] unpacking challenge: Your objective is to unpack the file deASPack.exe. To achieve this you can do anything you can think of. There is only one rule. Your unpacked file must unpack crackme.aspacked.exe file in such manner that file verify.exe says that the file unpacked.exe is valid. You can only modify/unpack the file deASPack.exe and any of your patches to it must not use the information obtained from the original unpacked.exe produced by the packed deASPack.exe. This means that your unpacked deASPack.exe file must create the valid unpacked.exe without patching it to write original data by force to unpacked.exe. To verify that everything works fine…
