2021-03-27 12:02:20 4487823 1131492 100 filesEach rar archive has a directory with 1000 files inside. I’ve extracted them all and checked for flag. Steps are
below.
7z x Hide\&seek.zip
for i in {1..100}; do 7z x Hide\&seek.zip; doneAs most of files seemed to be empty I’ve executed cat */*, which gave me the flag. Then I’ve also checked the below
just to find out where was the flag ;-)
grep SBCTF */* 81/367.txt:SBCTF{Y0U_H4VE_PL4Y3D_1T_W3LL}Flag
SBCTF{Y0U_H4VE_PL4Y3D_1T_W3LL}
