If you ever close an important view, you can always reopen it by clicking on its corresponding unit in the Project Explorer view, right-click, then Open View command.ĭid you know that JEB can decompile all sorts of formats? From Android dex to the classic x86 and Arm, less classic Mips, but also more exotic ones like Ethereum smart contracts compiled to EVM bytecode, or WebAssembly modules.

Depending on the code unit, different bases will be offered, including decimal, hexadecimal, octal, character, or binary string. Immediates can be rebased using the B hotkey (or via the Action menu, Convert command). You can explore a file, its structure, and analyze its constituents using the Project Explorer panel.

JEB handles any type of file, from raw bytes to PE to ELF to APK to DEX, but also archives, documents, etc. The first artifact will determine your project name, but other artifacts can be added whenever needed via the File menu, Add an Artifact command. JEB can handle more than one file in a single project. Press Space to switch back to the listing view. When located on a disassembled method, press the Space bar to switch from a flat listing to a CFG view of the method. This list is used by some code optimizers to further enhance decompilations.
no field update, directly or indirectly) outside of providing a return value. This Android analysis setting allows you to specify a list of methods which are guaranteed to have no side-effect (e.g. This analysis will use the decompiler, emulator, and sandboxing engine to find interesting things in the code, such as encrypted strings and constants or reflected accesses.Ĭustomizing the Emulator used by the Android Global Analysis #Ĭheck out the Emulator Settings command in the Android menu to customize the emulator and sandboxing engine policies and time-outs.
If you are analyzing an APK or Dex file, it is usually a good idea to run a Global Analysis pass. A code unit will generate a Disassembly document, among many other documents. Units can be rendered as documents, including text buffers, tables and trees. An artifact usually produces a tree of several units, including code units. In JEB, the analysis of an artifact (typically, an input file) yields objects called "units". Other actions, specific to a given class of files or analysis, are located in other menus (e.g. They include decompiling, renaming items, viewing cross-references, adding comments, etc. These commands are also accessible from the Navigation menu.Ĭommon analysis actions are located in the Action menu. Your project-wide list of bookmarks is accessible with F12. Type anything you can think of in this box.īookmark your favorite locations using the Control+F12 hotkey (Command+F12 on macOS). From strings to code, comments, bookmarks, command names, and text contents. It allows users to search and quickly visualize (and navigate to) any type of item referenced in your JEB project. The omnibox is a text input box located on the right side of the toolbar (default hotkey: F3). JEB Demo as well, but with several limitations. JEB Android ships with everything Android. JEB Community Edition bundles the x86 decompilers. Check which decompilers ship with your build by using the File menu, Decompilers command. You can navigate back to the Disassembly in a similar way. In the Disassembly view, right-click and select Decompile, or use the Action menu, Decompile command. If you are looking to decompile code, position yourself somewhere in the disassembly and hit the TAB key. You may navigate and modify your analysis via the Actions menu. Create a new project by opening a file (menu File, command Open) to be analyzed: it can be a PE file, an ELF file, an APK or DEX file, or anything else that your JEB build has plugin support for.Īfter an initial analysis pass, your main workspace will display an interactive disassembly listing, as well as a Project tree and a Code Hierarchy tree. Welcome! If this is your first run, you should be presented with an empty JEB workspace.
