cat /proc/<PID>/maps | grep libue4.so You’ll see a region like:
If you’ve ever tried to reverse engineer a mobile game built with Unreal Engine 4 , you’ve likely run into a wall: the real libue4.so is nowhere to be found. dump libue4.so
var m = Process.findModuleByName("libue4.so"); if (m === null) console.log("[!] libue4.so not found in memory"); else var base = m.base; var size = m.size; console.log("[+] Found libue4.so at " + base + " size: " + size); var data = ptr(base).readByteArray(size); var f = new File("/sdcard/libue4_dumped.so", "wb"); f.write(data); f.close(); console.log("[+] Dumped to /sdcard/libue4_dumped.so"); cat /proc/<PID>/maps | grep libue4
Instead, you see a tiny stub, a packed binary, or nothing at all. That’s because many developers encrypt, compress, or load the true UE4 native library dynamically at runtime. Remember: if the game is well-protected, you might
Remember: if the game is well-protected, you might need to bypass anti-tampering checks before dumping. That’s a battle for another blog post.
