1M IoT Radios open to Hijack by Telnet Backdoor.

Attackers can drop malware, add the device to a botnet or send their own audio streams to compromised devices. Imperial Dabman IoT radios have a weak password vulnerability that could allow a remote attacker to achieve root access to the gadgets’ embedded Linux BusyBox operating system, gaining control over the device. Adversaries can deliver malware, add a compromised radio to a botnet, send custom audio streams to the device, listen to all station messages as well as uncover the Wi-Fi password for any network the radio is connected to.
