Update (2020): Since writing this article, it has become, in a way, the go-to tutorial for learning radare2. Your feedback was amazing and I am very happy for the opportunity to teach new people about radare2. A lot has changed since I wrote this tutorial, both with radare2 and with me.
Are there any debuggers that can analyze radare2?
Depending upon your prior exposure to radare2, you may be surprised to know that, by default, radare2 does not perform any analysis at startup. Other disassemblers and debuggers like IDA Pro and x64dbg will automatically analyze the binary to identify functions, code and data. The author of radare2 (pancake), however, takes a different approach.
Why are so few people aware of radare 2?
It’s also my go-to tool for malware analysis tasks such as configuration retrievals. Sadly, I believe that only few people are familiar with radare2. It might be because they’re afraid to break out of their comfort zone (IDA Pro, x64dbg, Ghidra, OllyDBG, gdb) or they have simply not heard of it.
