This prevents malware to perform on device fraudulent transactions

Using MLIR for Dalvik Bytecode Analysis
Using intermediate representations allows analysts to write optimizations and code analysis passes easier than parsing binary or bytecode directly. Kunai is a library intended for static analysis of dalvik bytecode, in a newer version of the library, the idea is to use the capabilities and possibilities offered by MLIR, writing a new dialect centered on Dalvik instructions.
