JEB by PNF Software is a comprehensive reverse engineering platform for disassembly, decompilation, debugging, and analysis of code and document files. It supports multiple architectures including Android, x86, ARM, MIPS, RISC-V, WebAssembly, and Ethereum smart contracts. JEB enables reverse engineers and security auditors to analyze malicious code, perform security audits, and automate reverse engineering tasks. It translates machine code or bytecode back into a higher-level programming language representation, aiming to recover source code or a close approximation. The tool supports various file formats such as Android APKs, Windows PE, Linux ELF, Mach-O, and headless firmware. JEB provides an interactive graphical user interface and APIs for advanced code analysis, debugging, and automation. It allows for both manual analysis and automated pipelines for examining Android apps, native binaries, and other file types.
