Overview
We are given a website: gleaming-mermaid-1067e6.netlify.app. The description hints at finding a sealed truth.
Reconnaissance
Fuzzing directory paths or checking the site structure reveals a subdomain page located at /flag.
Exploitation Strategy
Accessing /flag yields a series of Base64 encoded strings. Decoding them outputs several flags. Looking at the challenge title (Uchiha's Redacted Memory), the real flag is STG{Pr0ud_t0_b3_an_Uchiha}.
Solution Code
# Decode list of base64 values:
echo 'U1RHe1ByMHVkX3QwX2IzX2FuX1VjaGloYX0=' | base64 -d
# Output: STG{Pr0ud_t0_b3_an_Uchiha}Flag
STG{Pr0ud_t0_b3_an_Uchiha}
