I also thought that was fornicationed up.

Interesting 🌝 this is reminded me to the old days, is it possible to create a tutorial video I don't see good unpacking tutorials theses days

Hello everyone I have been developing my own EXE protection and encryption system for a long time Taking inspiration from solutions like VMProtect and Themida I am trying to build a structure that includes various security layers such as packer encryption obfuscation anti dump and more To test this work and identify its shortcomings I prepared a small test EXE The application is a simple program that asks for a license key and your goal is to crack this application and gain access I encrypted and protected this test application using the protection system I developed Download link https://dosya.co/x5e4xyewg94d/CrackMe.exe.html VirusTotal analysis https://www.virustotal.com/gui/url-analysis/u-a65e75a253a80ae0a2ef0e23a218db163333faf2ce84401f76168cb764444c2a-a6822794 I kindly ask you to analyze it using reverse engineering techniques and try to break it and if possible share with me The parts you found difficult The weaknesses you found easy The strong and weak points of the protection My goal is purely to learn see my mistakes and make the system more robust For experienced experts it may be a simple application please excuse that in advance I hope it will be an educational exercise for beginners and intermediate level users Thank you in advance to everyone who participates Good luck to all

@cTrI the site will not disappear, bcoz the webdav server configured connection to single only no parallel connections allowed, if u use multiple winscp clients from the same location(ip) then u may abuse...

Any have any idea to handle this kind protection ?

Catch the exit and/or terminate process routine(s) (I assume the PE is auto-exiting when tampered with). And walk the stack back until you find the logic that controls the check(s).

No pressure; anyone can enjoy doing CTF challenges here. Old-day masters no longer exist

Sorry, I'm really short on time for tutorials. Besides it won't be much of use, as mostly custom tools are used. But I could try to answer some questions.

Should I download all the necessary courses now? They are truly amazing, but from what I know, WebDAV isn't very stable. I'm honestly worried that the site might disappear...but I'm worried that downloading (too much) might put too much strain on the server.

I don't know how to create exe with PyInstaller. Also I didn't finished my updates yet.

Use version.ASM to load your dll. compile with fasm.
