r2frida warning when hooking to process

[ethan-1106]

Please help me support the hooking issues of R2frida :(

Everytime i try to analysis the iOS Application with r2frida, it always return the following issue: r2 frida:///Headbook WARNING: r_bin_open_buf: assertion '(st64)opt->sz >= 0' failed (line 250)

Information note: Server - Client Frida version: 12.7.26

When installing the r2frida, i saw it get version 12.7.14. Is it the root cause of the client. I try to manually compile but that is not effective.

What about this? Please check the help usage and choose your election. The 2nd command is my suggestion.

$ r2 frida://?
$ r2 frida://spawn/usb//Headbook

Many thanks for your recommendation. 1 - use device id

2. as your suggestion:

I tried on all my devices : ipad mini 2 and iphone 6.

You don't have r2frida installed, do you?

Verify it with:

$ r2 -L|grep -i frida
rw_  frida    frida:// io plugin (MIT)

I already installed it as r2frida github recommendation.

The iOS appname does not seem to be correct.

This warning is because r2 is trying to parse a binary from memory of a 64bit address space in size which is obv not correct. Afaik this was fixed several months ago
