AOP-Based Attack on Obfuscated Java Code

A new approach to attack on obfuscated code is proposed using the join-point model and the bytecode instrument mechanism provided by AOP. All operations are implemented on bytecode level without acquiring the source code of target program, which makes obfuscation useless. As for attackers, they can modify the behavior of target code without decompiling and recompiling it. As experiment is shown, this approach to attack on obfuscated code is very straightforward and simple to be implemented.
