He "seeked" to the start of the code using the command s [vaddress] .
To understand what he was dealing with, Alex didn't run the file. He used , a tool from the Radare2 framework, to look at the "sections" of the file. He needed to find the .text section—the part of the file where the actual code lives. Action: He ran rabin2.exe -S RPDFE2.exe . RPDFE2.rar
A hidden message appeared in the code's logic. It wasn't a virus; it was a simple script that displayed a "Level 2 Clear" banner once decrypted. He "seeked" to the start of the code
With the address in hand, Alex opened the file in the main shell. This environment allows you to look at a program's "brain" without letting it actually perform any tasks. He needed to find the
Alex, a junior security analyst, found a file named RPDFE2.rar on an old training server. Inside was a single, obfuscated executable masquerading as a document. Instead of double-clicking it, Alex knew this was a puzzle designed to teach the "Radare2" workflow. 1. Inspecting the Skeleton
The cursor was now blinking at the very first instruction the computer would execute. 3. Translating Machine to Human
He printed the assembly code from the start to the end of the .text section.
