Binary Ninja
Binary Ninja is a reverse-engineering platform developed by Vector 35 Inc. It can disassemble a binary and display the disassembly in linear or graph views. It performs automated in-depth analysis of the code, generating information that helps to analyze a binary. It lifts the instructions into intermediate languages, and eventually generates the decompiled code. Binary Ninja supports various CPU architectures and binary executable formats. It runs on Windows, macOS, and Linux. It also has a free-to-use cloud version. History Binary Ninja was originally an internal tool for a CTF team. The developers later decided to form Vector 35 Inc and develop Binary Ninja into a commercial product. The development started in 2015 and the first public version was released in July 2016. The commercial product does not share code with the internal tool. The latter one is now open-sourced under GPLv2. Features and usage User interface Binary Ninja's UI is built using Qt.

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Capture The Flag (cybersecurity)
Capture the Flag (CTF) in computer security is an exercise in which "flags" are secretly hidden in purposefully- vulnerable programs or websites. It can either be for competitive or educational purposes. Competitors steal flags either from other competitors (attack/defense-style CTFs) or from the organizers (jeopardy-style challenges). Several variations exist. Competitions can including hiding flags in hardware devices, they can be both online or in-person, and can be advanced or entry-level. The game is based on the traditional outdoor sport of the same name. History Capture the Flag (CTF) is a cybersecurity competition that is used as a test of security skills. It was first developed in 1993 at DEFCON, the largest cybersecurity conference in the United States hosted annually in Las Vegas, Nevada. The conference hosts a weekend of cybersecurity competitions including CTF. There are two ways CTF can be played: Jeopardy and Attack-Defense. Both formats test participant’s knowl ...

Radare2
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 processor architectures and operating systems. History Radare2 was created in February 2006, aiming to provide a free and simple command-line interface for a hexadecimal editor supporting 64 bit offsets to make searches and recovering data from hard-disks, for forensic purposes. Since then, the project has grown with the aim changed to provide a complete framework for analyzing binaries while adhering to several principles of the Unix philosophy. In 2009, the decision was made to completely rewrite it, to get around limitations in the initial design. Since then, the project continued to grow, ...

JEB Decompiler
JEB is a disassembler and decompiler software for Android applications and native machine code. It decompiles Dalvik bytecode to Java source code, and x86, ARM, MIPS, RISC-V machine code to C source code. The assembly and source outputs are interactive and can be refactored. Users can also write their own scripts and plugins to extend JEB functionality. Version 2.2 introduced Android debugging modules for Dalvik and native (Intel, ARM, MIPS) code. Users can "seamlessly debug Dalvik bytecode and native machine code, for all apps ..including those that do not explicitly allow debugging". Version 2.3 introduced native code decompilers. The first decompiler that shipped with JEB was a MIPS 32-bit interactive decompiler. JEB 3 ships with additional decompilers, including Intel x86, Intel x86-64, WebAssembly (wasm), Ethereum (evm), Diem blockchain (diemvm). JEB 4 was released in 2021. A RISC-V decompiler was added to JEB 4.5. A S7 PLC block decompiler was added to JEB 4.16. Hist ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ghidra
Ghidra (pronounced gee-druh; ) is a free and open source reverse engineering tool developed by the National Security Agency (NSA) of the United States. The binaries were released at RSA Conference in March 2019; the sources were published one month later on GitHub. Ghidra is seen by many security researchers as a competitor to IDA Pro. The software is written in Java using the Swing framework for the GUI. The decompiler component is written in C++, and is therefore usable in a stand-alone form. Ghidra plugins can be developed in Java or in Python (provided via Jython). History Ghidra's existence was originally revealed to the public via WikiLeaks in March 2017, but the software itself remained unavailable until its declassification and official release two years later. In June 2019, Coreboot began to use Ghidra for its reverse engineering efforts on firmware-specific problems following the open source release of the Ghidra software suite. Ghidra can be used as a debugger sin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Decompiler
A decompiler is a computer program that translates an executable file to a high-level source file which can be recompiled successfully. It does therefore the opposite of a typical compiler, which translates a high-level language to a low-level language. Decompilers are usually unable to perfectly reconstruct the original source code, thus frequently will produce obfuscated code. Nonetheless, decompilers remain an important tool in the reverse engineering of computer software. Introduction The term ''decompiler'' is most commonly applied to a program which translates executable programs (the output from a compiler) into source code in a (relatively) high level language which, when compiled, will produce an executable whose behavior is the same as the original executable program. By comparison, a disassembler translates an executable program into assembly language (and an assembler could be used for assembling it back into an executable program). Decompilation is the act of using a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Disassembler
A disassembler is a computer program that translates machine language into assembly language—the inverse operation to that of an assembler. A disassembler differs from a decompiler, which targets a high-level language rather than an assembly language. Disassembly, the output of a disassembler, is often formatted for human-readability rather than suitability for input to an assembler, making it principally a reverse-engineering tool. Assembly language source code generally permits the use of constants and programmer comments. These are usually removed from the assembled machine code by the assembler. If so, a disassembler operating on the machine code would produce disassembly lacking these constants and comments; the disassembled output becomes more difficult for a human to interpret than the original annotated source code. Some disassemblers provide a built-in code commenting feature where the generated output gets enriched with comments regarding called API functions or parame ...

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...
