![]() ![]() Your character will start walking automatically and pass through each of the marked points without deviating from the predetermined path. This feature offers the possibility to pre-set a route with different stops. However, each speed has its advantages and disadvantages, depending on what the player intends at any given moment. This option allows you to move in the Pokémon world at different speeds, ranging from 0 km/h to 60 km/h. However, the easiest and fastest way would be to teleport wherever you need to go. If the virtual location is close to your real location, then you can select the option to walk there. To move to that location from where you are, you have two options: teleport or walk. PGSharp will transport you to any location where you can catch a Pokémon. That is, you don't need to physically travel to a specific location to access the Pokémon that are there. The map function allows you to move around the Pokémon world virtually. PGSharp not only allows you to move your Pokémon GO character without having to physically move in the real world, but it also includes various useful features such as: However, it is important to note that this practice is prohibited by Niantic, the developer of Pokémon GO, and your Pokémon Trainer Club account may be banned if they detect that you are using PGSharp or a similar app.Īll kinds of features to quickly catch Pokémon The main utility of PGSharp is to spoof your GPS location, which helps you catch more Pokémon, visit different gyms, and increase your chances of finding rare Pokémon. PGSharp allows you to move your character in the game with a virtual joystick without having to physically move in the real world. By moving, you can get closer to Pokémon to catch them or obtain items at PokéStops, among other activities. Normally, Pokémon Go uses your GPS signal to move your character on the map. Public void q () // your character without having to move in the real world It can help to dynamically identify which function is called: Since its prototype is (lua_State *L, StkId func, int nresults), luaD_precall Function that is involved when calling a C native function or a pure Lua function.The orange files are utilities, while the green ones This Lua bytecode is the result of the compilation of the original script with luac.īy hooking this function, we can recover the following files: Here is a basic block of a native function that uses the Lua API:Īmong all the Lua C functions, some of them are worth identifying to ease reverse engineering:īasically, it loads a Lua bytecode from a buffer given in parameter. The native library that implements the cheat functionalities and that contains the Lua VM being stripped, one of theĬhallenges lies in recognizing the Lua C API among the library’s functions 2. Add new opcodes ( OP_RUN, OP_GETDOWNVAL, OP_OLDTABLE, and OP_XXOR) to break decompilation and.Fake the version: try to make believe Lua 5.1 while it’s Lua 5.3.Some parts of the cheat are written in Lua whose VM has been modified to: It adds another layer to reverse, as we need to understand the VM architecture before being able to understand the original semantic of the code.īut what about using an interpreted language (like Python) and obfuscate its VM or its interpreter with O-LLVM? Some obfuscation techniques are based on transforming the original code through a VM (like VMProtect). ![]() Nevertheless, the obfuscation is relatively weak against emulation and static analysis 1. On the other hand, PGSharp uses different layers of obfuscation to prevent its analysis.įirst of all, it uses O-LLVM to obfuscate the native code that includes, at least, control-flow flattening and Gotta Catch ‘Em All: Frida & jailbreak detection),Īnd since only this part of the game is heavily obfuscated, it gives a hint about where the critical functionalities are. The Unity part is “compiled” into libil2cpp.so but we can recover some metadata with Perfare/Il2CppDumper.Īll the obfuscation is focused on libNianticLabsPlugin.so (c.f. Game is absolutely not protected, such as we have the original class and method names. It is worth mentioning that only a subset of the game is obfuscated. PokemonGO is a target of choice for reverse engineers and some critical functionalities are protected by a commercial solution.
