I just noticed a popup window on my Pi3 titled ATT7BMS46a. It's an input dialog box asking for a pre-shared key. The buttons are ok and cancel, the icon in the title bar is a yellow padlock.
Anybody recognize it? I didn't knowingly start anything new that needs keys and am slightly uneasy at its unbidden appearance. The machine is running Linux raspberrypi 4.9.28-v7+ #998 SMP Mon May 15 16:55:39 BST 2017 armv7l GNU/Linux, last updated a couple of days ago.
Thanks for reading and any thoughts.
