Modified UPX Unpacker

Recommended Posts

Hello master,

Is there a tool can automatically unpack modified UPX?

I found QuickUnpack v4.35 can't do this job well.

Please help how to use QuickUnpack correctly or there is another tool.

Thank you

PE Explorer, Resource Tuner have a UPX unpacker:

http://www.heaventools.com/

http://www.restuner.com/

 

IF not works standard Pushad/Popad - breaking on read to dword [ESP] after Pushad instruction

will do the trick.

 

Both of them can't automatically unpack (because it didn't detect of it) the modified UPX that i wanna unpack.

1) Why do you think it's a modified UPX?

2) Did you try CodeCracker's suggestion about standard pushad/popad method?

1. I simply analyze it with EXEinfo PE tool

2. I don't know how to do this manual job, thats why i ask if there an automatic tool that can do this job.

 

Btw, would you mind tell me how to do this manually with x64dbg may be.

Automatic tools will not teach you anything, try to understand the basic concepts and you will never need those automatic tools.
