More and more Smart TVs are connected to the Internet than ever before, with an estimated 760 million of them now connected globally. As new threats increasingly target IoT devices, such as Smart TVs, that include always-on connectivity and high-performance GPUs that can be hijacked for malicious purposes, FortiGuard Labs took the opportunity to look at the current security status of these devices.
FortiGuard Labs has been actively monitoring FALLCHILL, validating all its IOCs (indicators of compromise), and providing protection for our customers. In a previous post we provided a high level overview of FALLCHILL. In this research report we dig even further, providing a deep dive analysis of the FALLCHILL Remote Administration Tool (RAT) in order to shed additional light on this threat, and thereby help our customer and the security community at large defend against this threat and similar threats.
