Elvis on 2022-01-29 06:33: @X3eRo0: Then the answear to the flag is yes. I enjoy it a lot. Gonna make a write up soon :D

X3eRo0 on 2022-01-31 06:21: thanks @Elvis. Some writeups are already public because I used this challenge in Zh3r0 CTF v2 last year. I thought I should put it here as well. :)

X3eRo0 on 2022-02-01 16:25: @Elvis intended solution is to recover flag from just the trace.txt without looking at the shellcode (counting the for loop counter and getting the index in the random bytes array) !XD!
