ELFXtract : An Automated Analysis Tool Used For Enumerating ELF Binaries

ELFXtract is an automated analysis tool used for enumerating ELF binaries

Powered by Radare2 and r2ghidra

This is specially developed for PWN challenges and it has many automated features

It almost displays every details of the ELF and also decompiles its ASM to C code using r2ghidraDecompiling ELFs in Ghidra takes more time, but in elfxtract it decompiles and displays in few seconds Features in ELFXtract

* File info
* Shared object dependency details
* ELF Security Mitigation details / Checksec
* String details
* Header memory map
* ROP gadgets
* PLT Table
* GOT Table
* Function Table
* ASM code of functions
* Decompiled code of functions
* Predicting possible vulnerable functions Installation

git clone https://github.com/AidenPearce369/elfxtract
cd elfxtract
chmod +x install.sh
./install.sh
pip install -r requirements.txt

Working

You can run elfxtract with any ELF along with -ato list all details from the ELF

Threat: Ransomware Builder Babuk
Vulnerability: Insecure Permissions
Description: The malware creates directorys with insecure permissions when write to c:\ drive, granting change (C) permissions to the authenticated user group. Standard users can rename the executable dropped by the malware to disable it or replace it with their own executable. Then wait for a privileged user to logon to the infected machine to potentially escalate privileges.
