VIBRE is a conversational AI assistant that will help JEB users reverse-engineer your project files. It is backed by the LLM of your choice (commercial/remote, local, or our own end-point for free) and by JEB's MCP server (which can be started separately and used by any AI tools, not just VIBRE).

JEB 5.19 is available (pnfsoftware.com/jeb/changeli…). An interesting new feature in this release is a mixed boolean-arithmetic (MBA) expression simplifier/breaker. It gives interesting results on obfuscated code. Have a look at the snippet in image 1, which is a decompilation with MBA as well as other bitwise simplifications disabled. It is not easy to figure out that this code can be reduced to the MSB bit flip of its input, as seen in image 2. (The second input is pseudo-random and not used in the computation; its sole purpose is to obfuscate things further.) This feature is enabled by default in JEB, but can be disabled by turning off the IR optimizers tagged as "DEOBFUSCATOR" (option: EnableDeobfuscatorOptimizers) #ReverseEngineering
