Google CTF 2023: write-flag-where

The program prints its memory mappings and then, for any address and length you give, writes the flag there. The task is to make it print what it wrote.

Objective

Retrieve the flag from the challenge service.

The brief for this lab lives in its repository.

Submit evidenceSecret

Launch the lab

Open it in the Cyber CTF launcher, or run it yourself with Docker Compose.

Open in the launcher Source code

›Run it manually

$git clone https://github.com/CyberCTF/google-ctf-2023-write-flag-where && cd google-ctf-2023-write-flag-where && docker compose up -d

Without the launcher, the lab uses its public development evidence: great for practice, but it won't complete the lab.
