Hooah Trace

a simple yet powerful instruction tracing using frida stalker - supporting arm64 and x64

when you want to use this

when you need to trace at single instruction and perform additional operations or alter the code flow.

when you need to get a proper understanding of what's going on down there with obfuscations killing the party.

install

git clone https://github.com/iGio90/Hooah-Trace.git
npm install
npm link

try it out

cd example
npm link hooah-trace
npm install
npm run watch

# make your edits to index.ts
# inject the agent (quick att.py)

example code

import {HooahTrace} from "hooah-trace";

function onHookInstruction(context: CpuContext, instruction: Instruction) {
    // console.log(JSON.stringify(context));
    // console.log(JSON.stringify(instruction));
    // console.log('');
}

const target = Module.findExportByName(null, 'open');
if (target) {
    Interceptor.attach(target, function () {
        HooahTrace.trace({
            // print the execution blocks
            printBlocks: true,

            // -1 is endless
            count: -1,

            // do not trace jumps in excluded modules (i.e libc / libSystem)
            filterModules: ['libc.so'],

            // you can trace specific instructions with
            // instructions: ['svc', 'ldr']

            // style block prints
            printOptions: {
                // yes please
                colored: true,

                // custom space between blocks
                treeSpaces: 8,

                // include involved register values data
                details: true
            }
        }, onHookInstruction);
    });

roadmap

  • add syscall map for syscall tracing
  • add medium-level decompilation
  • add asm relocation
