What is Radare? And its features


What Is Radare2?


Ans. "Radare2 (also known as r2) is a complete framework for reverse-engineering and analyzing binaries; composed of a set of small utilities that can be used together or independently from the command line. Built around a disassembler for computer software which generates assembly language source code from machine-executable code, it supports a variety of executable formats for different processors and operating systems." - Wikipedia

In Simple Words, Radare is a Complete Framework That Can Help In Performing Various Type Of Activities, Operations And Functions with binary files. Basically, You Can Consider Radare As a Complete Set Of Tools And Scripts Written in C, That Help To Achieve Various Types Of Goals.



What is Reverse Engineering?

Ans. Actually, Radare in Starting Was Specially Design As A Reverse Engineering Frameworks. As You Can Read Into Their Official Website.

Radare is a portable reversing framework that can...

  • Disassemble (and assemble for) many different architectures
  • Debug with local native and remote debuggers (gdb, rap, webui, r2pipe, winedbg, windbg)
  • Run on Linux, *BSD, Windows, OSX, Android, iOS, Solaris and Haiku
  • Perform forensics on filesystems and data carving
  • Be scripted in Python, Javascript, Go and more
  • Support collaborative analysis using the embedded webserver
  • Visualize data structures of several file types
  • Patch programs to uncover new features or fix vulnerabilities
  • Use powerful analysis capabilities to speed up reversing
  • Aid in software exploitation




What is Binary Exploitation?

Ans. Because Of its Big List of Features. Experts Hacker normally use Radare For Binary Exploitation. Those Who Don't Know What it Is? Binary exploitation is the process of subverting a compiled application such that it violates some trust boundary in a way that is advantageous to you, the attacker.



What is Computer Forensic?

Ans. Forensic is Basically Reverse Engineering of Binary Files. Basically, In Forensic Their main motive is to collect as much as various type of useful information can collect. For More info.. Use Google.
