After running the ls command, we discovered a hidden folder named .trash and navigated into it.

ls -la
cd .trash/

Inside the .trash folder, there was a file named bin. We executed it, and it displayed some binary data.

./bin
00110000 01100100 01111001 01111000 01010100 00110111 01000110 00110100 01010001 01000100 00001010 

Next, we copied the binary to CyberChef to decode it.

Alternatively, if Perl is installed on the machine, you can use this command.

./bin | tr -d ' ' | perl -lpe '$_=pack"B*",$_'

Nice work! Proceed to the next round by using this flag.
