Overview
The binary does not reveal the flag directly upon execution, but contains a Base64-encoded string embedded in printable text.
Reconnaissance
Running strings chalpwn reveals suspicious Base64 string: aHdqezF0XzFzX24wdF9lNHN5XzM0MTlrOTN9Cg.
Exploitation Strategy
Decode the Base64 payload using command-line tools or CyberChef.
Solution Code
echo "aHdqezF0XzFzX24wdF9lNHN5XzM0MTlrOTN9Cg" | base64 -d
# Output: hwj{1t_1s_n0t_e4sy_3419k93}Flag
hwj{1t_1s_n0t_e4sy_3419k93}
