Today, Mandiant disclosed a critical risk vulnerability in coordination with the Cybersecurity and Infrastructure Security Agency (“CISA”) that affects millions of IoT devices that use the ThroughTek “Kalay” network. This vulnerability, discovered by researchers on Mandiant’s Red Team in late 2020, would enable adversaries to remotely compromise victim IoT devices, resulting in the ability to listen to live audio, watch real time video data, and compromise device credentials for further attacks based on exposed device functionality. These further attacks could include actions that would allow an adversary to remotely control affected devices.
At the time of writing this blog post, ThroughTek advertises having more than 83 million active devices and over 1.1 billion monthly connections on their platform. ThroughTek’s clients include IoT camera manufacturers, smart baby monitors, and Digital Video Recorder (“DVR”) products. Unlike the vulnerability published by researchers from Nozomi Networks in May 2021 (also in coordination with CISA), this latest vulnerability allows attackers to communicate with devices remotely. As a result, further attacks could include actions that would allow an adversary to remotely control affected devices and could potentially lead to remote code execution.
