Debuggers

Cutter

RE Platform powered by Rizin framework (previously it was the GUI for radare2).

Both 32 and 64-bit versions. It also includes the following plugins:

Plugin name	Description
ASLR Removal	Creates a copy of the target executable without the ASLR bit set
checksec	Checks for security features in the target
Multiline Ultimate Assembler	Assembler that makes the reverse engineer's like much easier
ScyllaHide	Must have plugin to deal with anti-debug routines
SwissArmyKnife	I mainly use it to import .MAP files generated from IDA
xAnalyzer	Analyse API function calls to show you the parameters
YaraGen	Generate Yara rules based on code from targets

In %AppFolder%\x64dbg\scripts folder you will also find scripts to help with the unpacking of PECompact, UPX, FSG, MPRESS and others.
