What comes before main , I wonder …. Note: flag format : flag{XXXXXXX}

q1

Debug binary in gdb and get the pass bytes:

0x555555755450 <pass>:		0x26202d27	0x7029153a	0x74701e74	0x7533021e
0x555555755460 <pass+16>:	0x003c383b	0x00000000	0x00000000	0x00000000

The bytes are XORed with 0x41 and contain the flag.

flag: flag{Th15_15_Cr4zy}
