Hi,

I Was Just Wondering If There Was Any Plans To Add 32 Bit Support To This?

When trying to lift driver, it falls with AV in vm_context::fetch (I think due wrong vip). If i remove constant 0x100000000 in vm_instance::initialize_context and make preferred_image_base = 0x10000 lift is success, but not sure that output is right.

unp_scylla.zip

with this loader

        std::vector<uint8_t> b1 = read_file("1.bin");
        vmpattack instance(b1);
        int my_rva = 0x7E4A1D; //0x740B47;//0x342861;
        if (auto result = instance.analyze_entry_stub(my_rva))
        {
            if (auto routine = instance.lift(result->job))
            {
                vtil::optimizer::apply_all_profiled(*routine);
                vtil::save_routine(*routine, "1_routine.vtil");
            }
        }

Give me exept on line 52 - memcpy( &read_value, ( void* )vip, size ); in vm_contenxt.hpp;
(Potential Branch Destinations: {0x10}) - prey

Also, some patches has been added, for VMPAttack, because VTIL API PE sessions part is updated.

And, thanks for the VMPDump and Attak! ) It really helped to understand the structure of the VMP from the inside)

Hi Adam, thank you for release. I see you hardcode .text section name for search. This is a bad idea. There could be many protected executable sections. Just list all sections, find executable ones, filter out vmp sections and process them. I'd pr but have no time currently, anyways it shouldnt be hard at all.

I'm stuck after lifting to VTIL , what to do next to unpack the exe after the dump & lift and make it executable again and not broken , ps : dumped via scylla.

Thanks

Can you make a release? I can't compile it

hello friend.
I want to ask if I want to improve it to x86, where should I start, and what information should I read?
hope to get some help.
sincere thanks.

Hi,

This tool seems very interesting, however I'm not sure what to do with the binary VTIL files it produces. Would it be possible to output the IL as readable text instead as an option? Or is there a free tool available that opens VTIL files?

In compiling the project I get

  main.cpp
