"Protecting Java Code" by Mike Dulaney

Sponsored by Arxan

Abstract:
While Java offers an efficient framework for developing and deploying enterprise and Web 2.0 server or client-side applications, it also presents many security risks. Perhaps chief among those risks is that Java’s bytecode contains highly detailed metadata which makes compiled applications quite easy to reverse engineer, tamper and pirate.

In our discussion we will consider and demonstrate some of the vulnerabilities and risks that threaten Java applications. These threats consist of:

• Easy decompilation
– Hackers can quickly decompile your bytecode with free or low-cost Java decompilers that process bytecode to produce readable source code, which they modify to implement hacks or create counterfeits
• Reverse engineering
– After download to the client, reverse engineer a bytecode file and decompile the code for IP theft or bypass critical routines
• Bypass critical routines
– Thick client patches to bypass authentication logic or exploit restricted functionality contained that enable server attacks
• Key and credential theft
– Secret keys or authentication credentials simply identified, and can then be abused to launch server attacks

We will also discuss protection tools you can use when assessing or implementing Java application security.
