Where does the cross reference in Ida come from?
The cross reference in our case originates from the address 0x00436608, so the current function is called on that address. We also see the arrow pointing up, which indicates that the function that calls the current function is located upward the disassembly code (has a lower virtual address).
Where do you find the code xref in Ida?
On the picture above we can see the function at address 0x00436629 that contains the cross reference comment: the CODE XREF. The code references are presented as “CODE XREF”, whereas the data cross references is presented as “DATA XREF”; in our case we can see it’s a code cross reference.
What’s the difference between code and data cross references?
The code references are presented as “CODE XREF”, whereas the data cross references is presented as “DATA XREF”; in our case we can see it’s a code cross reference. The cross reference in our case originates from the address 0x00436608, so the current function is called on that address.
How are cross references marked in xrefs-InfoSec?
We can see that the data cross references are marked with the “DATA XREF” string and use the name and offset if the function is known or virtual address if function is not known to denote the location the data was accessed from.
How to identify the address of a function in Ida?
Identifying references to a function in IDA proves to be quite simple, as the XrefsTo () API function does exactly this. For this script, I’m going to hardcode the address of the decryption script. The following code can be used to identify the addresses of the references to the decryption function.
How to get cross references to a struct?
In order to do this, firstly, i need to get the list of cross-references to a given structure type (e.g. struct BITMAPINFO) which can be found in “Structure” subview in IDA. I know IDA provides this function from version 6.2 by right-button mouse clicking on the structure name and selecting “List cross references to”.
How can I access another graph in Ida?
This is why Ida has another graph that can be accessed by selecting View – Graphs – User xrefs chart, which we can interact with in various ways.
