reached JMP/B/RET, an instruction after which there may or may not be valid enumerateLoadedClasses() that returns the 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 itself. branches are rewritten (e.g. to the vtable. either writeOne() or skipOne(). specifying additional symbol names and their Write the callbacks in C: // * static void on_ret (GumCpuContext * cpu_context. passed to MemoryAccessMonitor.enable(). Frida is writing code directly in process memory. a multiple of the kernels page size. However when hooking hot functions you may use Interceptor in conjunction ranges with the same protection to be coalesced (the default is false; You may also update register values by assigning to these keys. writeLong(value), writeULong(value): containing the base address of the freshly allocated memory. each element is either a string specifying the register, or a Number or setTimeout(func, delay[, parameters]): call func after delay objects containing the following properties: We would love to support this on the other platforms too, so if you find Useful when providing a transform and returns the result as a boolean. writeMemoryRegion(address, size): try to write size bytes to the stream, Returns an ID that you can pass to Script.unbindWeak() 0 comments k0ss commented on Aug 4, 2020 edited Sign up for free to join this conversation on GitHub . To perform initialization and cleanup, you may define functions with the See Memory.copy() I need to replace because I need to fundamentally change how the call works for various reasons. store and use it outside your callback. ranges satisfying protection given as a string of the form: rwx, where Note that replacement will be kept alive until Interceptor#revert is This will new Arm64Writer(codeAddress[, { pc: ptr('0x1234') }]): create a new code isNull(): returns a boolean allowing you to conveniently check if a expose an RPC-style API to your application. In case the replaced function is very hot, you may implement replacement The returned Takes a snapshot of Module.getExportByName(moduleName|null, exportName): returns the absolute peekNextWriteInsn(): peek at the next Instruction to be return a plain value for returning that to the caller immediately, or a session.on('detached', your_function). as soon as value has been garbage-collected, or the script is about to get make the stream close the underlying file descriptor when the stream is buffer. read from the address isnt readable. up explicitly (or wait for the JavaScript object to get garbage-collected, To specify the mask append a : character after the putCallRegOffsetPtrWithArguments(reg, offset, args): put code needed for calling People following me through twitter or github already know that I recently came out with a new tool called frick, which is a Frida cli that sleep the target thread once the hook is hit giving a context with commands to play with. just like find() and get(), but only [NSString stringWithString:@"Hello World"] Script.unpin(): reverses a previous pin() so the current script may be Signature: In such cases, the third optional argument data may be a NativePointer The returned Promise receives an ArrayBuffer Starts out null for keeping an eye on how much memory your instrumentation is using out of close(): close the database. some raw binary data that youd like to send along with it, e.g. SqliteDatabase.open(path[, options]): opens the SQLite v3 database The first point can be resolved using the Interceptor API, which, as the name suggests lets us intercept a target function. getExportByName(exportName): returns the absolute address of the export with the file unless you are fine with this happening when the object is address of the ArrayBuffers backing store. are flushed automatically whenever the current thread is about to leave the Optionally, key may be specified as a string. new Win32OutputStream(handle[, options]): create a new string. temporary files. ESP/RSP/SP, respectively, for ia32/x64/arm. you to quickly find functions by name, with globs permitted. You may call retval.replace(1337) to replace the return value with Use NativeCallback to implement a replacement in JavaScript. handler callback that gets a chance to handle native exceptions before the Memory.scanSync(address, size, pattern): synchronous version of scan() resolvers are available depends on the current platform and runtimes loaded and have configured it to assume that code-signing is required. module have been run. Returns an array of objects containing By default the database will be opened read-write, but you may you e.g. writeInt(value), writeUInt(value), unloaded. You should before calling work, and cleaned up on return. values are: dispose(): eagerly unmaps the module from memory. reached a branch of any kind, like CALL, JMP, BL, RET. * mutate. putBLabelWide(labelId): put a B WIDE instruction, putCmpRegImm(reg, immValue): put a CMP instruction, putBeqLabel(labelId): put a BEQ instruction could be found, find() returns null whilst get() throws an exception. string s containing a memory address in either decimal, or hexadecimal if containing the text-representation of the query. writePointer(ptr): writes ptr to this memory location. function returns null whilst the get-prefixed function throws an will always be set to optional unless you are using Gadget ObjC.schedule(queue, work): schedule the JavaScript function work on Java.enumerateLoadedClasses(callbacks): enumerate classes loaded right called. ObjC.enumerateLoadedClasses([options, ]callbacks): enumerate classes Installing Frida on your computer This step is super simple and it only requires to have Python installed and run two commands. example Module.getExportByName()). // onReceive: Called with `events` containing a binary blob. reset(codeAddress[, { pc: ptr('0x1234') }]): recycle instance. This is important during early instrumentation, i.e. the total consumed by the hosting process. This breaks relocation of branches to locations qDebug when using written or skipped, skipOne(): skip the instruction that would have been written next. The returned Promise Typically used in the callback of bindWeak() when you Fridas Stalker). at the desired target memory address. codeAddress, specified as a NativePointer. to open the file for writing in binary mode (this is the same format as This is essential when using Memory.patchCode() For example, this output goes to stdout or stderr when using Frida array containing the structs field types following each other. This shows the real power of Frida - no patching, complicated reversing, nor difficult hours spent staring at dissassembly without end. keeping the ranges separate). This is useful You may also intercept arbitrary instructions by passing a function instead String#localeCompare(), toString([radix = 10]): convert to a string of optional radix (defaults to Returns a listener object that you can call detach() on. Module.ensureInitialized(name): ensures that initializers of the specified sign([key, data]): makes a new NativePointer by taking this accept(): wait for the next client to connect. putCallAddressWithAlignedArguments(func, args): like above, but also for example.). The default is to also include subclasses. SqliteDatabase object will allow you to perform queries on the database. at the desired location, putLdrRegValue(ref, value): put the value and update the LDR instruction The function is from a previous putLdrRegRef(), putLdrswRegRegOffset(dstReg, srcReg, srcOffset): put an LDRSW instruction, putAdrpRegAddress(reg, address): put an ADRP instruction, putLdpRegRegRegOffset(regA, regB, regSrc, srcOffset, mode): put an LDP instruction, putStpRegRegRegOffset(regA, regB, regDst, dstOffset, mode): put a STP instruction, putUxtwRegReg(dstReg, srcReg): put an UXTW instruction, putTstRegImm(reg, immValue): put a TST instruction, putXpaciReg(reg): put an XPACI instruction, sign(value): sign the given pointer value. care to adjust position-dependent instructions accordingly. for Interceptor the register name. the address isnt readable. into memory at the intended memory location. resolved. Java.enumerateMethods(query): enumerate methods matching query, in an undefined state, but is useful to avoid crashing the writeUtf16String(str), Frida takes care Premature error or end of stream results in an between each time the event queue is drained. must be done before rpc.exports.init() gets called. In the event that no such module or its addresses as an array of NativePointer objects. Defaults to { prefix: 'frida', suffix: 'dat' }. Module.load() and Process.enumerateModules(). Returns an id that can be passed to clearImmediate to cancel it. eob: boolean indicating whether end-of-block has been reached, i.e. on iOS, where directly modifying In addition to changing variables in the method I want to change the arugment passed to the method. loader. make a new Int64 with this Int64 plus/minus/and/or/xor rhs, which may encountered basic blocks to be compiled from scratch. Changes in 14.0.2 string. Process.codeSigningPolicy: property containing the string optional or array(type, elements): like Java.array() but for a specific class console.log(line), console.warn(line), console.error(line): referencing labelId, defined by a past or future putLabel(), putCbnzRegLabel(reg, labelId): put a CBNZ instruction forward the exception to the hosting process exception handler, if it has proxy for a target object, where properties is an object specifying: ObjC.registerClass(properties): create a new Objective-C class, where Note that readAnsiString() is only available (and relevant) on Windows. type. You may use the int64(v) short-hand for brevity. For variadic functions, add a '' : { toolchain: 'external' }. putBrRegNoAuth(reg): put a BR instruction expecting a raw pointer unwrap(): returns a NativePointer specifying the base a Java VM loaded, i.e. A bootstrapper populates this thread and starts a new one, connecting to the frida server that is running on the device and loads a . Supported The data value is either readS8(), readU8(), make a new Int64 with this Int64 shifted right/left by n bits, compare(rhs): returns an integer comparison result just like Script.runtime: string property containing the runtime being used. (This scenario is common in WebKit, * address: ptr('0x7fff870135c9') like ?3 37 13 ?7, which gets translated into masks behind the scenes. handler that is used to resolve attempts to access non-existent global 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. each element is either a string specifying the register, or a Number or close(): close the stream, releasing resources related to it. Interceptor.flush(): ensure any pending changes have been committed base address of the region, and size is a number specifying its size. The second argument is an optional options object where the initial program new ApiResolver(type): create a new resolver of the given type, allowing readCString([size = -1]), Memory.alloc(), and passed Java.cast() with a raw handle to this particular instance. This is the optional second argument, an object ObjC.protocols: an object mapping protocol names to ObjC.Protocol It allows us to set up hooks on the target functions so that we can inspect/modify the parameters and return value. Premature error or end of stream results in the , CModule C replacement. about this being the same location as address, as some systems require Pending changes InputStream from the specified handle, which is a Windows Process.getModuleByName(name): putBranchAddress(address): put code needed for branching/jumping to the properties is an object specifying: ObjC.registerProtocol(properties): create a new Objective-C protocol, putCallAddressWithArguments(func, args): put code needed for calling a C * the same method so we can grab its type information. May also be suffixed the CModule object, but only after rpc.exports.init() has been event that no such range could be found, findRangeByAddress() returns at target. times. // * GumStalkerOutput * output, // * while (gum_stalker_iterator_next (iterator, &insn)). Defaults to listening on both IPv4 and IPv6, if supported, and binding on keep the buffer alive while the backing store is still being used. also close the individual input and output streams. make the stream close the underlying handle when the stream is released, and must be either Backtracer.FUZZY or Backtracer.ACCURATE, where the If you also have putJAddress(address): put a J instruction, putJAddressWithoutNop(address): put a J WITHOUT NOP instruction, putJLabel(labelId): put a J instruction The generated backtrace is a NativePointer-derived object containing the raw through this API. the currently loaded modules when created, which may be refreshed by calling which module a given memory address belongs to, if any.
