frida-17

This skill is a compatibility reference and fixer for scripts written for Frida 17, the dynamic instrumentation toolkit (version 17.0.0, released May 2025). It solves the concrete problem that Frida 17 removed and renamed a large set of JavaScript APIs, so scripts written for older versions break; the skill detects deprecated usages and provides the correct modern replacements. It is used when writing, reviewing, fixing, or migrating Frida scripts.

The guide documents the specific breaking changes: static Module methods (findBaseAddress, findExportByName, enumerateExports, and similar) now require Process and instance methods; static Memory read/write helpers are replaced by NativePointer instance methods; callback-style enumeration APIs now return arrays; and certain built-in names such as hexdump must not be overridden. It enumerates valid NativePointer conversion, memory read/write, and pointer-arithmetic methods, covers the unchanged Java bridge API for hooking class methods and overloads, explains Java byte-array handling, and provides common patterns such as waiting for a library to load, hooking libc functions with Interceptor.attach, and a custom hex-dump helper. It ends with a ten-item migration checklist and links to official Frida release notes and API docs.

Because Frida is a dual-use dynamic instrumentation framework used for reverse engineering and runtime hooking of applications, including memory reading/writing and intercepting native and Java functions, this material is inherently dual-use security tooling. The target users are mobile reverse engineers, security researchers, and pentesters who write Frida instrumentation scripts. The content itself is an API migration reference and does not contain exploit payloads, but the underlying techniques it documents can be applied to bypass or tamper with application behavior.
