I was wondering if you could get the dll saved into your hard drive from the respective .dmp file. Also if not, is it possible to fully get the asm code from the same .dmp file in addition to it .data/.text sections bin file? By getting the asm code I mean just like you would get if you'd open an unpacked .exe in IDA(So you'd be able to reconstruct functions into c code etc)
not sure what is respective dump file if you have a .dmp (full kernel memory dump )
and you have loaded it in windbg you can use .writemem command to write back the pages back
kd> lm m null Browse full module list start end module name fcad2000 fcad2b80 Null (pdb symbols) e:\symbols\null.pdb\77840F8CB3624E438D5D2F0913E4D30E1\null.pdb kd> r cr3 cr3=00039000 kd> ?? @$proc->Pcb.DirectoryTableBase unsigned long  0x81291848 0x39000 kd> .writemem c:\null.bin fcad2000 L?(fcad2b80-fcad2000) Writing b80 bytes..
Yes it's possible, but there's no automation of this process. Technically it's similar to the process of unpacking: you get the memory dump of the executable(in you case you need to extract dll from the memory dump), adjust PE header, so that the sections match the offsets in the dump, set OEP if needed, recover import section, recover the relocations.
If you just want to disasm the dll, and not going to reuse the binary, then you may just open dmp file in IDA and find it there among the modules. IDA allows you to disassemble it right in the dump, though you won't be able to apply signatures. And the imports will not be shown, since dmp is a mix of all modules of the process.
