Fatmike Posted September 19 Share Posted September 19 (edited) View File Fatmike's Crackme #5 ..::[FaTmiKE 2o24]::.. Welcome to my 5th crackme! It took a long time implementing this, i hope it is hard to solve! Sorry for the long load time of the crackme Here are the goals: 1. The main goal is to unpack and uncrypt this crackme. 2. Find a valid serial or write a keygen. If you only succeed in 1. or 2. it's fine, i am happy to read every solution. (e.g. if you can find a valid serial without unpacking, please write a tutorial how you did it!) The crackme was tested on windows 10. Have fun! PS: 1.) Windows Defender returns a false positive due to my custom protection. If you do not trust me, please use a VM for reversing the crackme. 2.) The crackme has to be started from explorer.exe The crackme can also be found here: https://crackmes.one/crackme/66ca5b91b899a3b9dd02af52 Submitter Fatmike Submitted 09/19/2024 Category UnPackMe Edited September 20 by Fatmike 1 Link to comment Share on other sites More sharing options...
jackyjask Posted September 19 Share Posted September 19 Does not run on Windows7 eats 100% of one CPU and no any GUI rendered... 1 Link to comment Share on other sites More sharing options...
Fatmike Posted September 19 Author Share Posted September 19 (edited) Nope, sorry. Windows 7 is not supported. It works on Windows 10, i haven't tested it on Windows 11. It needs some startup time due to custom protection... Edited September 19 by Fatmike 1 1 Link to comment Share on other sites More sharing options...
jackyjask Posted September 19 Share Posted September 19 how long is the bootup time? 1 Link to comment Share on other sites More sharing options...
Fatmike Posted September 19 Author Share Posted September 19 (edited) Only a couple of seconds on native Windows 10. It takes just a bit longer than you would usually expect for a small crackme. Not sure how much longer it takes in a vm. Edited September 19 by Fatmike 1 Link to comment Share on other sites More sharing options...
jackyjask Posted September 19 Share Posted September 19 OK, thanks for reply with details I just tried this crackme also on Win11 24H2/VBox VM same behavior as on W7 -hangs in processes, eats one full CPU core I waited 1min then killed it PS W11 defender says this is a virus and deleted the file, so I"ve to shut it up 1 Link to comment Share on other sites More sharing options...
Fatmike Posted September 19 Author Share Posted September 19 (edited) No problem Quote I just tried this crackme also on Win11 24H2/VBox VM I heard it works with Virtualbox with Windows 10. And there it takes 3-4 seconds for startup. Quote PS W11 defender says this is a virus and deleted the file, so I"ve to shut it up As i wrote in the description: PS: Windows Defender returns a false positive due to my custom protection. If you do not trust me, please use a VM for reversing the crackme. I hope you can still make it run somehow 😕 Edited September 19 by Fatmike 1 Link to comment Share on other sites More sharing options...

Fatmike Posted September 19 Author Share Posted September 19 (edited) Have you tried starting directly from explorer? @jackyjask: I have just tested it on Windows 11 23H2 in Virtual Box and it works fine, if you start it from explorer!
