Runs fine here on XP, W7 & W8. Hidden from the taskbar by default (easy to find the call).

ok its done by design, thought my OS is acting weird. ok i will give it a try.

SHA384?

 

fun(sn) = Mid(SHA384(username), 0x11, 0x20); ---> success!

sha384 is 5% from algo but even here you are wrong.

ChOoKi.

Will be hints with block cipher part?

It would be too soon to start posting valid combos, let's just hope someone solves it without hints/help. Best of luck to all. :peace:

This is sad but I would seriously like to know how to unpack this crap


 


(or the name of the packer)

The old ESP trick land just one command below OEP.


The the file can be unpacked as usual once you have landed on the OEP.

More or less, you see the packer destroys the usual alignement of the IAT table causing the final dumped PE to be misaligned. And since I *STILL* use imprec and imprec does not have the PE rebuilder/fixer tool my final unpacked file would be non working, thanks for Lord_PE for that one
