The good news is that, even though this is being announced today, the vulnerability has been fixed since September of last year.
Security researchers have discovered a vulnerability in Ring doorbells that exposed the password for the Wi-Fi network it was connected to. Bitdefender said the Amazon-owned doorbell was sending its owner’s Wi-Fi password in cleartext as the doorbell joins the local network, allowing for nearby hackers to intercept the Wi-Fi password and gain access to the network to launch larger attacks or conduct surveillance.
