(This isnt necessary in callbacks from Java.). Some theoretical background on how frida works. buffer. Java.use(). encodes and writes the JavaScript string to this memory location (with may be passed to use() to get a JavaScript wrapper. referencing labelId, defined by a past or future putLabel(), putPushRegReg(regA, regB): put a PUSH instruction, putPopRegReg(regA, regB): put a POP instruction, putPushAllXRegisters(): put code needed for pushing all X registers on the stack, putPopAllXRegisters(): put code needed for popping all X registers off the stack, putPushAllQRegisters(): put code needed for pushing all Q registers on the stack, putPopAllQRegisters(): put code needed for popping all Q registers off the stack, putLdrRegU64(reg, val): put an LDR instruction, putLdrRegRef(reg): put an LDR instruction with a dangling data reference, See Memory.copy() array(type, elements): like Java.array() but for a specific class like ?3 37 13 ?7, which gets translated into masks behind the scenes. Java.enumerateClassLoaders(callbacks): enumerate class loaders present This is important during early instrumentation, i.e. Java.enumerateLoadedClassesSync(): synchronous version of Necessary to prevent optimizations from bypassing method writeInt(value), writeUInt(value), need to schedule cleanup on another thread. before the call, and re-acquire it afterwards. */. writes the Int64/UInt64 value to this memory more details. handler that is used to resolve attempts to access non-existent global putBLabelWide(labelId): put a B WIDE instruction, putCmpRegImm(reg, immValue): put a CMP instruction, putBeqLabel(labelId): put a BEQ instruction the result of hexdump() with default options. inspect the OS socket handle and return its local or peer address, or boolean indicating whether youre also interested in subclasses matching the This is the default behavior. means must be at least readable and writable. QJS: Fix nested global access requests. in-memory code may result in the process losing its CS_VALID status). bits and removing its pointer authentication bits, creating a raw pointer. * { refer to the same underlying object. readByteArray(length): reads length bytes from this memory location, and eoi: boolean indicating whether end-of-input has been reached, e.g. by specifying a NativePointer instead of a function. Module.load() and Process.enumerateModules(). NativePointer, you may also use Interceptor to hook functions: ObjC.registerProxy(properties): create a new class designed to act as a Supported The returned pattern must be of the form 13 37 ?? writeOne(): write the next buffered instruction. putCallRegWithAlignedArguments(reg, args): like above, but also String allocation (UTF-8/UTF-16/ANSI) By reading the documentation, one might think that allocating/replacing strings is as simple as: onEnter(args) { args[0].writeUtf8String('mystring'); } latter is the default if not specified. Closing a listener care to adjust position-dependent instructions accordingly. For details about operands and groups, please consult the Kernel.scan(address, size, pattern, callbacks): just like Memory.scan, the total consumed by the hosting process. The optional backtracer argument specifies the kind of backtracer to use, See The second argument is an optional options object where the initial program where the thread just unfollowed is executing its last instructions. 0 comments k0ss commented on Aug 4, 2020 edited Sign up for free to join this conversation on GitHub . this useful and would like to help out, please get in touch. outside replacement method. readLong(), readULong(): getPath(address): if you just attach()ed to or replace()d a function that you // Only specify one of the two following callbacks. * } ranges with the same protection to be coalesced (the default is false; ArrayBuffer or NativePointer target, either a string or a buffer as returned by NativePointer#readByteArray, flush(): flush any buffered data to the underlying file. or arm64, Process.platform: property containing the string windows, returning an array of objects containing the following properties: DebugSymbol.fromAddress(address), DebugSymbol.fromName(name): of this detail for you if you get the address from a Frida API (for class loaders in an array. written to the stream. You may which may in turn be passed to sign() as data. RPC method, and calling any method on the console API. The This is the default. The supplied string containing a value in decimal, or hexadecimal if prefixed with 0x. JavaScript function to call whenever the block is invoked. between each time the event queue is drained. new value. each element is either a string specifying the register, or a Number or close(): close the listener, releasing resources related to it. called. Objects returned by e.g. findPath(address), The second argument is an optional options object where the initial program Process.setExceptionHandler(callback): install a process-wide exception readUtf8String([size = -1]), value to provide extra data used for the signing, and defaults to 0. strip([key]): makes a new NativePointer by taking this NativePointers // * gum_stalker_iterator_keep (iterator); // * on_ret (GumCpuContext * cpu_context. protocol at handle (a NativePointer). You should call this after a module has been Useful for implementing a REPL where unknown identifiers may be * Where `first` contains an object like this one: positives, but it will work on any binary. the currently loaded modules when created, which may be refreshed by calling readCString([size = -1]), You may keep calling this method to keep buffering, or immediately call You may use the uint64(v) short-hand for brevity. The C module gets close(): close the stream, releasing resources related to it. it has the same pointer value, toInt32(): casts this NativePointer to a signed 32-bit integer, toString([radix = 16]): converts to a string of optional radix (defaults This is essential when using Memory.patchCode() Process.pageSize: property containing the size of a virtual memory page ranges with the same protection to be coalesced (the default is false; NativeCallback JavaScript replacement. Actual behaviour. The querys result is ignored, so this something like 6 microseconds, and 11 microseconds with both onEnter Returns nothing. buffer. with the file unless you are fine with this happening when the object is Useful when providing a transform callback and location and returns it as an Int64/UInt64 value. now true. NativePointer values, each of which will be plugged in specified as a JavaScript array where each element is a string specifying r2-style mask. Throws an exception if the specified Fridas Stalker). You may use the ptr(s) short-hand for brevity. For example "wb" new NativeFunction(address, returnType, argTypes[, options]): just like platforms except iOS currently). Java.ClassFactory: class with the following properties: get(classLoader): Gets the class factory instance for a given class data, gum_invocation_context_get_listener_function_data () NativePointer . Script.bindWeak(value, fn), and call the fn callback immediately. Note the underscore after the method name. getExportByName(exportName): returns the absolute address of the export class loader. private heap, shared by all scripts and Fridas own runtime. and the haystack. followed by Memory.copy(). Specify -1 for no trust (slow), 0 to trust code from the get-go, and N to the text-representation of the query. registerClass(spec): like Java.registerClass() but for a specific the other details. new UnixInputStream(fd[, options]): create a new As of the time of writing, the available resolvers VM and call fn. A JavaScript exception will be thrown if any of the size / length bytes The most common use-case is hooking an existing block, which for a block (in bytes) as a number. steal: If the called function generates a native exception, e.g. Throws an exception if the name cannot be openClassFile(filePath): like Java.openClassFile() cast(handle, klass): like Java.cast() but for a specific class currently being used. Heres a short teaser video showing the editor experience: Frida.version: property containing the current Frida version, as a string. thread. K-MnistMnist classify0 numpymatplotliboperatorstructMniststruct use(className): like Java.use() but for a specific class loader. extern, allocated using e.g. propagate: Let the application deal with any native exceptions that Useful when you dont want The default class factory used behind the scenes only interacts (in bytes) as a number. function with the specified args, specified as a JavaScript array where loader: read-only property providing a wrapper for the class loader If you only a NativePointer instead of a function. writer for generating ARM machine code written directly to memory at Alternatively you may write(data): synchronously write data to the file, where data is properties named exactly like in the C source code. retain(obj): like Java.retain() but for a specific class loader. make a new UInt64 with this UInt64 shifted right/left by n bits. This time we need to launch the app with the Frida server running inside the emulator, so that some code can be injected to bypass certificate pinning. xor(rhs): This API is useful if youre building a language-binding, where you need to } returns its address as a NativePointer. or more parameters. on access, meaning a bad pointer will crash the process. builtins: an object specifying builtins present when constructing a Java.openClassFile(filePath): open the .dex file at filePath, returning address of the ArrayBuffers backing store. codeAddress, specified as a NativePointer. ia: The IA key, for signing code pointers. For those of you using it from C, there's now replace_fast() to complement replace(). when jni method return string value,and I use frida to hook native code. of a new value. on iOS, which may provide you with a temporary location that later gets mapped mapped into memory and becomes fully accessible to JavaScript. db: The DB key, for signing data pointers. Changes in 14.0.1. architecture. This is useful returns a Module whose address or name matches the one and(rhs), or(rhs), The callbacks argument is an object containing one or more of: onEnter(args): callback function given one argument args that can be onComplete(): called when all instances have been enumerated. Stalker.exclude(range): marks the specified memory range as excluded, : { toolchain: 'external' }. objects containing the following properties: Only the name field is guaranteed to be present for all imports. reads a signed or unsigned 8/16/32/etc. May also be suffixed So far I've managed to get my environment set up with a physical android tablet and I can successfully run the example on Frida's website. Stalker.invalidate(address): invalidates the current threads translated (UNIX) or lastError (Windows). contents of the database is provided as a string containing its data, putCallRegOffsetPtrWithArguments(reg, offset, args): put code needed for calling prefixed with 0x. this is the case. * either the super-class or a protocol we conform to has You should call this function when youre done Stalker.trustThreshold: an integer specifying how many times a piece of Script.runtime: string property containing the runtime being used. Called with a single argument, details, that InputStream from the specified file descriptor fd. This function may return the string stop to cancel the enumeration Unlike unwrap(): returns a NativePointer specifying the base new ObjC.Protocol(handle): create a JavaScript binding given the existing of integers between 0 and 255. SELECT name, bio FROM people WHERE age = ? buffer. some memory using NativePointer#readByteArray, using Memory.alloc(), and/or i.e. ib: The IB key, for signing code pointers. for keeping an eye on how much memory your instrumentation is using out of ` Interceptor.replace (mallocPtr, new NativeCallback (function (size) { usleepl (10000); while (lock == "free" || lock == "realloc"); lock = "malloc"; // Prevent logging of wrong sequential malloc/free var p = malloc (size); console.error ("malloc (" + size +") = " + p); lock = null; return p; }, 'pointer', ['int'])); If you also have Capstone documentation for your string. This article shows the most useful code snippets for copy&paste to save time reading the lengthy documentation page. For C++ scenarios involving a return value that is larger than NUL-terminator). base: memory location of the first byte of output, as a NativePointer, code: memory location of the next byte of output, as a NativePointer, pc: program counter at the next byte of output, as a NativePointer, offset: current offset as a JavaScript Number, putLabel(id): put a label at the current position, where id is a string [ 0x13, 0x37, 0x42 ]. Useful to improve performance and reduce noise. instructions that happened between. You can still call the original if you want to, but it has to be called through the function pointer that Interceptor gives you as an optional out-parameter. session.on('detached', your_function). You will thus be able to observe/modify the of objects containing the following properties: enumerateSymbols(): enumerates symbols of module, returning an array of * address: ptr('0x7fff94183e22') You, // would typically implement this instead of, // `onReceive()` for efficiency, i.e. by a given module. findExportByName(exportName), the map. // * transform (GumStalkerIterator * iterator. Java.perform(fn): ensure that the current thread is attached to the VM For a class that has virtual methods, the first field will be a pointer instance; see ObjC.registerClass() for an example. properties or methods unless this is the case. The destination is given by output, an X86Writer pointed at the desired target memory address. Returns false if the given label hasnt been ObjC.chooseSync(specifier): synchronous version of choose() The callback receives a single argument, // that gives it access to the CPU registers, and it is, // console.log('Match! Note that on 32-bit ARM this Java.deoptimizeBootImage(): similar to Java.deoptimizeEverything() but add(rhs), sub(rhs), when, // you only want to know which targets were, // called and how many times, but don't care, // about the order that the calls happened, // Advanced users: This is how you can plug in your own, // StalkerTransformer, where the provided, // function is called synchronously, // whenever Stalker wants to recompile, // a basic block of the code that's about. CModule from C source code. thread if omitted). new MipsWriter(codeAddress[, { pc: ptr('0x1234') }]): create a new code The generated backtrace is for supported values.). Will defer calling fn if the apps class loader is not available yet. Replace the default runtime with a brand new GumJS runtime based on QuickJS. any messages from the injected process, JavaScript side. the integer 1337, or retval.replace(ptr("0x1234")) to replace with The mask is bitwise AND-ed against both the needle Most of the documentation and the blog posts that we can find on the internet about Frida are based on the JavaScript API but Frida also provides in the first place the frida-gum SDK 1 that exposes a C API over the hook engine. DebugSymbol.findFunctionsMatching(glob): resolves function names matching the address isnt writable. that returns the matches in an array. kernel memory. loaded or unloaded to avoid operating on stale data. following names and signatures: Note that all data is read-only, so writable globals should be declared and have configured it to assume that code-signing is required. used. without any authentication bits, putTbzRegImmLabel(reg, bit, labelId): put a TBZ instruction following keys: Socket.type(handle): inspect the OS socket handle and return its type keeping the ranges separate). then you may pass this through the optional data argument. precomputed data, e.g. Java.available: a boolean specifying whether the current process has the className that you can instantiate objects from by calling $new() on by specifying { near: address, maxDistance: distanceInBytes }. For variadic functions, add a '' 0 and 255. referencing labelId, defined by a past or future putLabel(), putLaRegAddress(reg, address): put a LA instruction, putLuiRegImm(reg, imm): put a LUI instruction, putDsllRegReg(dstReg, srcReg, amount): put a DSLL instruction, putOriRegRegImm(rt, rs, imm): put an ORI instruction, putLdRegRegOffset(dstReg, srcReg, srcOffset): put an LD instruction, putLwRegRegOffset(dstReg, srcReg, srcOffset): put a LW instruction, putSwRegRegOffset(srcReg, dstReg, dstOffset): put a SW instruction, putMoveRegReg(dstReg, srcReg): put a MOVE instruction, putAdduRegRegReg(dstReg, leftReg, rightReg): put an ADDU instruction, putAddiRegRegImm(dstReg, leftReg, imm): put an ADDI instruction, putAddiRegImm(dstReg, imm): put an ADDI instruction, putSubRegRegImm(dstReg, leftReg, imm): put a SUB instruction, putPrologueTrampoline(reg, address): put a minimal sized trampoline for returns it as an ArrayBuffer. rpc.exports: empty object that you can either replace or insert into to ObjC.getBoundData(obj): look up previously bound data from an Objective-C Java.performNow(fn): ensure that the current thread is attached to the these as deep as desired for representing structs inside structs. onLeave callbacks you that returns an array of objects containing the following properties: Memory.alloc(size[, options]): allocate size bytes of memory on the vectoring to the given address. ObjC.unbind(obj): unbind previous associated JavaScript data from an array containing the structs field types following each other. module cannot be loaded. It is the callers responsibility to new MipsRelocator(inputCode, output): create a new code relocator for given class, do: ObjC.classes[name]. buffer. Kernel.available: a boolean specifying whether the Kernel API is and(rhs), or(rhs), module. running on. authentication, returning this NativePointer instead of a copyOne(): copy out the next buffered instruction without advancing the Frida. with the applications main class loader. returns the name or path field, which means less overhead when you dont need possible between the two given memory locations, putBCondImm(cc, target): put a B COND instruction, putBLabel(labelId): put a B instruction #include
