I assume some grey-hat realized the crosswalk computer used a default password and decided the only way the city was likely to fix the problem was this.

"The EPBS will compare the system security code with the code entered on the E-Configurator. If the code matches, you will have an opportunity to change the code. Press NO to continue on without any change. Press YES if you want to change to a new security code at this time. Entering a new code uses the same technique just described, using the Left/Right and Down keys. It is necessary to use a security code different from the default AAAA. Failure to change the code will cause a periodic message to play – “CHANGE PASSWORD”." they just didn't RTFM and that password is still set to AAAA
- lupire 5y agoSo when the device is deployed insecurely, it broadcasts itself to the public to invite a takeover? Why wouldn't it just decline to operate at all until the password is set?
- moltke 5y ago> just decline to operate at all until the password is set? This truly is the right way to handle PSK auth. The "UX" for it isn't as nice as some people would like though.
- bombcar 5y agoI took it as that was what it was doing. It refuses to do crosswalky things until you set the password (likely a power failure or something caused it to lose it’s config). The troll thing to do is set a password if you find one of them in the wild.
- JPKab 5y agoCompletely unacceptable. See my other post in this thread talking about the high concentration of blind/visually impaired pedestrians in Crystal City. This is far more dangerous than if done in other places. I doubt the knucklehead grey-hat realized that.
