Carrier: Chaos Static - SEC-T CTF 2026 Writeup
Description
The Stockholm board keeps pointing at a bigger one, a long-distance call away and cheaper after eleven. That one does not take new users.
It does not have to. Somebody on Stockholm has been handing the reader account out for years, to anybody who asks in the right place.
The second board. Dial in through Carrier.
Solution
While reading messages on the Stockholm board in Carrier, two posts mention a German board called Chaos Static.
From these messages we get the number 009-49-40-23 41 57 and a guest login.
From the modem prompt we use ATDT0094940234157 to connect to the new board.
Logging in with the guest account reaches the main menu.
The message area exposes several readable posts.
The flag is in the last message.
