alza2 on 2022-05-27 13:34: Interesting. Getting the flag isn't that difficult, but the executable seems rather different from a typical non .NET compiled binary. Throwing to a disassembler like Ghidra doesn't give much info. Judging by the name of the executable, is it using some sort of .NET obfuscator?

doneday on 2022-07-01 21:53: Where does the program set the values of "array" before being decoded from Base64? All I see is "array = new char[num2]"?

Used ILSpy to analyze the binary, found the password comparison in Main, and copied the exact obfuscated code into my local compiler, running it gave me back the password
