“…The research conducted in 2012 about various Smart TV security implementations revealed that all of the tested vendors had vulnerabilities [35]. In [36], the authors presented that it is possible to build a system for remote parental control by hacking a Samsung Smart TV. In [37], this idea has been improved and expanded into remotely managed Kids Mode.…”

Smart TV devices are gaining increasingly more popularity. Due to their nature, Smart TVs can access a lot of sensitive data. This is one of the reasons why the Smart TV has become a popular target of hacking recently. Manufacturers try to make such attacks more difficult, and one of the methods they use is the removal of symbols from the firmware. In principle, this would prevent or significantly hinder the preparation of malwares or homebrew that could run on different firmware versions. This article is focused on developing algorithms for automatic symbol resolution. We proposed two automatic symbol resolution methods designed for Smart TVs. Presented methods were tested on the firmwares of the most popular Smart TV manufacturers’, Samsung and LG, devices. Furthermore, an original framework is presented, which automatically locates the desired function in the binaries based on characteristic strings used in or near searched function. The developed framework is commonly used by homebrew developers (e.g., SamyGO) and releases developers from hardcoding function’s addresses for different firmwares.

“…In our work instead the process of age recognition is more challenging since the faces on which the age is estimated are extracted from live streams. Another effort toward exploiting smart device capabilities is shown in Reference 29, where the authors focusing on extending parental control capabilities through rooting on smart‐TVs. This approach though needs specifically modified smart‐TVs and software installed to them, that may cause instability of the operating system and break of the warranty.…”

In this article we present an application of the Usage Control paradigm to a Smart Home infrastructure, based on a model extension and structured use of obligations. In the proposed extended model obligations are exploited to enforce two different access revocation time, namely revoke and suspend. This increases the policy expressiveness and enable to optimize the resource usage. Furthermore, obligations are exploited to send commands via IFTTT to different interconnected Smart Home devices, to impose safety-relevant behaviors, or to act on policy attributes to implement a self-healing paradigm for revoked sessions. The article is motivated by a parental control use case where deep learning is used in combination with Usage Control to regulate dynamically viewing rights of a smart-TV and interactions with interconnected devices. Accuracy and performance experiments show the effectiveness and feasibility of the proposed work.

“…It is currently difficult to imagine life without it; washing machines, refrigerators, watches, mobile phones, and televisions are increasingly equipped with modules that allow remote connection with other devices and become a part of the internet of Things (IoT) [4][5][6]. More importantly, more and more of these devices have access to our personal data, and that means that securing these devices against unauthorized access from outside is increasingly important [7][8][9][10][11]. A few years ago, most of us mainly cared about the security of our PCs; the security of mobile devices was a new thing, not very popular yet.…”

The smart TV market is growing at an ever faster pace every year. Smart TVs are equipped with many advanced functions, allow users to search, chat, browse, share, update, and download different content. That is one of the reason why smart TVs became a target for the hacker community. In this article, we decided to test security of Tizen operating system, which is one of the most popular smart TV operating systems. Tizen is used on many different devices including smartphones, notebooks, wearables, infotainment systems, and smart TVs. By now, there are articles which present security mechanisms of Tizen OS, and sometimes with a way to bypass them; however, none of them are applicable to the smart TVs. In the article, we focused on developing an algorithm that will allow us to gain root access to the smart TV. The proposed attack scenario uses CVE-2014-1303 and CVE-2015-1805 bugs to bypass or disable security mechanisms in Tizen OS and finally gain root access.
