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:

Does not run on Windows7

eats 100% of one CPU and no any GUI rendered...

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...

how long is the bootup time?

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.

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
 

No problem

I heard it works with Virtualbox with Windows 10. And there it takes 3-4 seconds for startup.

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 😕

Confirmed working in:

• Win10 x64 22H2 inside VMWare;
• Win10 x86 2004, build 19041 inside VMWare;
• Win10 x64 22H2 real machine;

Takes ~5 seconds to start up.

 

@jackyjask:

Spoiler

it hates when it's not started from explorer.exe - could that be a problem?  

 

@kao : Thanks for pointing out the issue with explorer, i will add it to the description

I did - turned off the realtime scanner

but then it hangs as I wrote above

 

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!

Edited September 20, 2024Sep 20 by Fatmike

nope, not from explorer

I'm old fan of TC

so running always ing from it, I dont like explorer, even hate it. .. sorrry

I can't believe that it matters how do you run it??
