Report Summary:
Android bet365 live casino review have been widely adopted by developers to protect apps from being plagiarized. Meanwhile, various unpacking tools unpack the apps through direct memory dumping. To defend against these off-the-shelf unpacking tools, bet365 live casino review start to adopt virtual machine (VM) based protection techniques, which replace the original Dalvik bytecode (DCode) with customized bytecode (PCode) in memory. This defeats the unpackers using memory dumping mechanisms. However, little is known about whether such bet365 live casino review can provide enough protection to Android apps.
To shed light on these questions, we take the first step towards demystifying the protections provided to the apps by the VM-based bet365 live casino review and propose novel program analysis techniques to investigate existing commercial VM-based bet365 live casino review including a learning phase and a deobfuscation phase. We aim at deobfuscating the VM-protected DCode in three scenarios, recovering the original DCode or its semantics with training apps, and restoring the semantics without training apps. We also develop a prototype named Parema to automate much work of the deobfuscation procedure. By applying it to the online VM-based Android bet365 live casino review, we reveal that all evaluated bet365 live casino review do not provide adequate protection and could be compromised.
