Overcoming Fear: Reversing With Radare2
summary
Claim: radare2 is approachable and practical for real reversing tasks; demos show concrete results. The session patches a crackme by patching conditional jump with 0x90 0x90 to accept any password, then uses emulation via ESIL to compute the expected password and to decrypt an obfuscated PE32 section by running the decryptor until the code becomes readable. It uses i/o cache for in-memory patches so disk stays unchanged, and a r2pipe Python script automates decryption. Also covers Cutter, r2frida, r2pm and six‑week releases.
