Challenge of Reverse Engineering

Here is an unpackme of Obsidium 1.3.5.5... http://www.tuts4you.com/download.php?view.2340 Ted.

Good Luck! ASProtect_UnPack_Me.rar

try to unpack it unpackME.rar

Hi mates! I've modified a little bit ExeFog packer (made by Bagie), removed some crap which i consider unuseful by the moment (CreateMutex?, Morphine? (well, i've removed this because it get detected by all AV )).. and added "some" protection... just have a look to the unpackme Thanx goes to Bagie for his sources Any ideas for improvement will be good received Enjoy it!

Attached is an unpackme from my own protector, Ultra version. Though lARP v2.0 Ultra supports compression, I haven't done so for this UnpackMe. I added quite a lot of features in comparison with Lite, Standard and Pro versions. It might have become harder to unpack but that's why I coded in a messagebox + exit (warning for debugging or VM), which should be an excellent point of attack. The real stuff doesn't have this messagebox nor exit though (See previous versions). Unpack and tell me about its flaws. I want to explicitly thank my buddy jstorme for providing me with ideas, testing on x64 and to always have kept pushing me over the edge. I would not have continued…

Armadillo_UnPack_Me.rar

quosego, lets see how this one goes should be a bit more of a pain then the last one.. (used sdk this time).. Good luck all This has all (except file patching) that WinLicense has to offer. WinLicense_v2.0.1.0_UnPackMe_2.rar

Well don't expect it to be easy. Any dumb can serialfish it. Keygenning isn't for everyone. Rules: ->>>FiShInG wIlL nOt Be CoNsIdErEd SoLuTiOn<<<- ->>>No PaTcHiNg<<<- ->>>Writte a KeyGen<<<- Solvers: -HVC, 1sT -Encrypto (asta) -Serial Killer (asta) Link: [hide] http://www.megaupload.com/?d=KV2XXN8M[/hide]

Catch My Anti.Debug/Anti.Attach Trick !!! anyone knows how we can bypass without patching main file memory ? Anti_Dump.zip

??? MbCrackMe.zip

This is my 2Nd challange written by me, make shure you find out why is this level 5. Rules are: -NO patching -NO bruteforcing -Making a keygen/Serial Fish are allowed solutions. -GOLD MEDAL {Keygenned}: DrPepUr - Keygen accepted -SILVER MEDAL {Serial Fished}: None ZUMASGENME2.zip

Hi there ! try this : CrackMe.zip

We are testing our GBA emulator and added a protection to it. Can you bypass it? We need to know this, because we want to make it harder to crack/bypass. NOTE: There are no rules, bypass the messagebox as you want, loader, patcher, whatever! But, make sure you tell us how you did it! File is located here (in the rar archive): LINK! Goal: Get past the first window message... Good Luck! NOTE: Can you also post how you did it, as a summary. Thanks, I will appreciate it very MUCH!

please try it.. my friend sent it to me but i can't solve it Yt__o_KeygenMe2.zip

I worked on a target with this algo when a little after I started reversing. It gave me a hard time fishing a serial so I just patched it and went about my way. I have this thing of going back to old targets and finding new solutions. Anyway recently keygenning has peaked my interests so I brought out PROGRAMX to see if I could keygen it. I couldnt belive how simple it was. It was right there smacking me in the face, anyway thought it would be a good exercise.. So I ripped the algo and modified a couple things and I leave you with this. No Anti, no other b/s just straight code. DrPepUr_6.rar Dustyh1981

Hello everybody! This is my first attempt at a keygen. I've tried to protect it the best i know. keygenme.zip http://www.megaupload.com/?d=06NNMUMKTell me if it's any good or where i can make it better. Thanks.

hi all people in this here i written a Serial Fishing for all cracking boards for testing Level : Hard Attached to this topic just find a valid serial , you not allow crack it if you found a valid serial , plz send it to my mail address : giotin_underseh@yahoo.com Regards , GioTiN Serial_Fishing__1_Under_SEH_Team.rar

Hello again everyone. This time it might be my final keygenme depends on real life issues you can download it here : http://www.encrypto.co.nr/crackmes/Keygenme.9.dEPENDENCE.zip i have a few things to say: this keygenme involves math crypto . good for intermediate crackers and starters of course This keygenme is dedicated to SerialKiller a good mentor and a good friend. Mynes i have to say thanks again for skinning this junk HMX0101 for reporting bugs and testing. I hope you like this one . Enjoy.

After lARP v2.0 Lite and lARP v2.0 Standard editions, here is an unpackme protected by lARP v2.0 Pro Ed. It is supposed to be challenging Have fun lena151. lARP_v2.0_Pro_UnpackMe.rar

hi, Info: Pack and Obfuscate with {SA} and use System.Reflection Namespace for protecting .NET Framework 2 is Need CrackME.zip

this is a CrackME (5) for NewBies by Me ok try get "serial & name" CrackME_5.rar

Here ya go, DrPepUr #5 I based this off a couple apps I worked on rolled them up into one and added a personal touch. Shouldnt be too hard. There are no rules all solutions ar valid as long as it runs registered and all options are unlocked. Patch, Keygen, Loader, Bruteforce just whatever you gotta do. Good Luck, Dustyh1981 DrPepUr5.rar
