Collect garbage: deletes any unused memory pages from the database.

Pack database (Deflate): the same as the previous option, except the database files are compressed in the.

idb of the previous session is overwritten. id0, id1, nam and til databases and donвЂ™t create.

DonвЂ™t pack database: flush changes to.

We can choose from the following options:

Therefore, IDA can analyze the executable without the actual executable, and with only the database archive file.ДЄnytime weвЂ™re trying to close the currently open.idb database (the currently analyzed executable), IDA asks us if we would like to save changes to the disk. idb files to other researchers without the malicious executable. This is a useful feature that can be used to pass around. Moreover, IDA doesnвЂ™t even require the executable anymore we can now work with just the. idb database has been created for a specific executable, IDA wonвЂ™t need to analyze the program again when we load it later.

name.til вЂ“ contains information about local type definitionsДЄll of these file formats are proprietary and can only be used in IDA.

name.nam вЂ“ contains index information related to named program locations,.

name.id1 вЂ“ contains flags that describe each program byte,.

name.id0 вЂ“ contains contents of B-tree style database,.

Upon opening a new file to analyze with IDA Pro, it analyzes the whole executable file and creates an.idb database archive. In our case, it was the pe.llx that was able to recognize the analyzed file and display itself as the вЂњPortable executable for 80386вЂќ option.ДЄfter we click on the OK button, IDA Pro will load a file as if it was loaded by the operating system itself.

On my version of IDA Pro, the loaders directory contains the following files: dbg.llx, elf.llx, macho.llx, pe.llx. Any file loader that can recognize the analyzed file will be presented and we will be able to choose any of them. IDA Pro will automatically present the file types that can be used to work with the loaded file. The list of file types generated from the list of potential file types is located in IDA ProвЂ™s loaders directory. Usually, the executable architecture and processor type are recognized successfully and we wonвЂ™t need to change that in the presented window. The processor modules are located under IDA ProвЂ™s procs directory in my case, the following modules are available: arm.ilx and pc.ilx. The processor type specifies the processor module that will be used to disassemble the executable. This can be seen on the picture below, where the Processor Type of вЂњIntel 80Г—86 processors: metapcвЂќ is detected. It will also recognize the architecture the executable was compiled against.

Upon opening the executable, IDA Pro will automatically recognize the file format of the executable: in our case, it is a PE Windows executable. I guess whenever weвЂ™ve been working on some file already, itвЂ™s best to click on the Previous button to open one of the files weвЂ™ve been working on in the past. We can also disable the вЂњDisplay at startupвЂќ checkbox in the bottom of the window presented on the picture above so that IDA Pro runs only when we want to use it. WeвЂ™ll select the reverse Meterpreter executable that we previously created with Metasploit framework. When IDA Pro is first loaded, a dialog box will appear asking you to disassemble a new file, to enter the program without loading any file, or to load the previously loaded file.
