Decompiler

Decompile a function in a binary to C-like pseudocode.

When to use

• View the decompiled source code of a function

• Analyze function logic and control flow

• Understand what a function does before deeper analysis

Instructions

Using the VulHunt MCP tools, open the project (open_project ) and run the following Lua query (query_project ), adapting it as needed:

local d = project:decompile(<target_function>)

return tostring(d)

Possible values for <target_function> :

• A string, e.g. "system"

• An AddressValue

• VulHunt APIs return addresses as an AddressValue

• To build an AddressValue, use for example: AddressValue.new(0x1234)

• A regex, e.g. {matching = "<regex>", kind = "symbol", all = true}

• A byte pattern, e.g. {matching = "41544155", kind = "bytes", all = true}

all is a boolean. If set to true , it returns a table containing all matching functions. If false (default), it returns only the first matching value. The for loop is not necessary if the function target is only one (i.e. all is not set to true)

Returns the decompiled C-like pseudocode as a string.
