this is fun. it seems most of these crosswalks can be configured via app from https://polara.com/ . So either the authentication was leaked or got physically flashed/hacked?

> PASSWORD ISSUES: The iCCU can be connected to thru Wi-Fi. The buttons can be connected to thru Bluetooth. A. Once Wi-Fi is turned on at the iCCU, the Wi-Fi password is DEFAULT1 (ALL CAPS). B. Following power up, each button will say “change password” every 30 seconds, until the default password is changed. There is one shared password for logging into an iCCU and all PBS connected to it. The factory default password is 1234. Using a Field Service app, use 1234 to log into the iCCU or any PBS the first time, and change the password. This changes the password for all PBS and the iCCU. See Section 5.2 in the Manual for details. C. If the password is unknown, a Password Reset requires a call to Polara Tech Support.
