My apologies if this question is very basic. I have found this string in my Android application Binary that was built using the flutter framework. This is a 32 bit ARM library. I found the location of a url string at "00c88fa0" located below. I want to find the assembly code that loads and uses this string. I used Ghidra's "show call trees" and "Show references to address" functionality, but they have been unable to help me. I assume the string is being referenced by a base address + offset calculation. Is there an easy way for me to find this section of the code? Or is it not easily possible because there are too many base + offset calculations that could arrive at my String?

Thank you.

    Have you made sure the whole .text section has been disassembled? If not the xref would not have been created.

  • I did another run of the autoanalyzer changing a few settings. I think it has disassembled more of the text section and added functions to the symbol tree. However, I don't see any xref links to this string. I am sure this string is used as well.

  • Have you looked a little before the actual string? Suppose it is a counted string, you'd expect something like "maximum" and "current length" before the string (or, if there is no flat version of the counted strings, such record could point to the string you have identified).

  • I edited my post with more bytes. Actually a bit of background what I am doing is that this url was originally a https url. As part of a pen test I am conducting I wanted to intercept the traffic and needed to downgrade the connection to http instead of https. In the past I achieved this by removing the "s" in the url and padding the end of the string with a null byte thinking that it would terminate 1 byte early. This time the null byte gets added to the url. So long story short I do believe that this is a counted string. I wanted to find the counting code so that I could fix it and learn.

  • I'd be surprised if there were many servers not automatically redirecting http->https these days... it would be quicker to check for redirection in a browser first rather than modify the app. Nov 23, 2022 at 22:52

In Ghidra, it is possible to view the references to a given address in memory as shown in the picture: How to see references to a string in memory
