Search for raw byte patterns (hex sequences) in binary code.
Using the VulHunt MCP tools, open the project (open_project) and run the following Lua query (query_project), adapting it as needed:
local result = project:search_code("<byte_pattern>")
if result then
local entry = {
function_address = tostring(result.function_address),
start_address = tostring(result.start_address),
end_address = tostring(result.end_address),
instructions = {},
}
for _, insn in ipairs(result.insns) do
table.insert(entry.instructions, {
mnemonic = insn.mnemonic,
address = tostring(insn.address),
})
end
return entry
end
The byte pattern is a hex string (e.g., "554889e5................", where .. matches any byte).
Returns a JSON object containing:
function_address - the address of the function containing the matchstart_address - the start address of the matched patternend_address - the end address of the matched patterninstructions - list of matched instructions with their mnemonics and addressesFor UEFI targets, additional functions and options are available:
-- Search code within sw_smi_handlers
local result = project:search_code("<byte_pattern>", "sw_smi_handlers")
-- Search code within child_sw_smi_handlers
local result = project:search_code("<byte_pattern>", "child_sw_smi_handlers")
-- Search for a protocol GUID (returns a boolean)
local guid_found = project:search_guid("5B1B31A1-9562-11D2-8E3F-00A0C969723B", "EFI_LOADED_IMAGE_PROTOCOL_GUID")
-- Search for an NVRAM variable (returns a boolean)
local nvram_found = project:search_nvram("GetVariable", "PlatformLang", "8BE4DF61-93CA-11D2-AA0D-00E098032B8C")
-- Search for a protocol (returns a boolean)
local protocol_found = project:search_protocol("LocateProtocol", "PCD_PROTOCOL_GUID", "11B34006-D85B-4D0A-A290-D5A571310EF7")
-- Search for a PPI (returns a boolean)
local ppi_found = project:search_ppi("LocatePpi", "PPIName", "9C21FD11-434A-12D3-D10D-109048052C8A")

/code-pattern-matching) - For higher-level semantic pattern matching in decompiled code, while byte-pattern-matching works at the raw instruction level/decompiler) - Decompile matched code to understand what the byte pattern representsInteract with the Binarly Transparency Platform (BTP) via CLI commands for uploading firmware, running scans, downloading BA2 archives, and pushing custom rules. Use when you need to interact with the Binarly Transparency Platform or working with BA2s.
Find all locations where functions are called in a binary. Use when analyzing callers of a function, checking call relationships, or identifying which functions invoke a specific API.
Search for code patterns in decompiled output using Weggli semantic matching. Use when finding vulnerable code constructs like unchecked memcpy, buffer operations, or specific function call patterns in pseudocode.
Track data flow between function parameters, calls, and arguments using taint analysis. Use when detecting vulnerabilities like command injection, buffer overflows, or tracing user input to dangerous functions.
Decompile a function to C-like pseudocode for human-readable analysis. Use to understand function logic, review control flow, or prepare for code pattern matching.
Find and list functions in a binary by name, address, regex, or byte pattern. Use as the starting point for binary analysis, to locate specific functions, or to enumerate all functions matching criteria.
