Challenge Lore
During a network reconnaissance, you've discovered an ancient terminal system still running on port 23. The system claims to be from 1987 and uses "basic authentication" for administrator access.
The authentication mechanism appears to be implemented in C, and given the era, modern security practices were likely not a priority. Can you find a way to bypass the password check?
Hint: Sometimes old code has old problems.
