Briefing

intel://sss/briefing_08.txt

SIGINTKraken’s Rest, 11:21 local. The MV Longvinik is berthed at the far end of the quay. Her maintenance network runs open. Someone was on it for forty-three minutes.

Harbour traffic was captured from the quay during the window. It is noisy — half a dozen networks named after ships that have no business being here.

Most of what you’ll see is exactly what it claims to be. One thing isn’t. Whoever was on board didn’t need bandwidth — they needed cover. Operator, find what left the Longvinik.

Objective

Find what one network is hiding and submit it as the flag.
