Samsung , being a large multinational company , makes a lot of products spread across various spheres of life and marketed to diverse segments in a multitude of countries . Over here on XDA-Developers , Samsung is famously known for their Android smartphones and tablets , given they are some of the top contenders for their respective product categories . Samsung also makes many more interesting electronics , including a few “ smart ” ones that run on its own open-source OS , Tizen OS . Tizen powers Samsung products like smart TVs , smartwatches like the Gear series and even mobile phones like the Samsung Galaxy Z lineup . Samsung is seeking to expand the Tizen offerings to more products and more markets , as is evident from the expansion of the Galaxy Z smartphones and the Gear smartwatches . As security researcher Amihai Neiderman of Equus Software mentioned Vulnerability-related.DiscoverVulnerability to Motherboard , Samsung ’ s Tizen OS has as many as 40 zero-day vulnerabilities still active and posing threat to the security of the operating system . These vulnerabilities allow someone to remotely hack “ millions ” of newer Samsung smart TVs , smartwatches and mobile phones , both already on the market as well as ones slated for future release as Samsung does not know Vulnerability-related.DiscoverVulnerability and has not fixed Vulnerability-related.PatchVulnerability these vulnerabilities ( hence , “ zero day ” ) . You can see that nobody with any understanding of security looked at this code or wrote it . It ’ s like taking an undergraduate and letting him program your software ” . All of the vulnerabilities allow remote code execution on a Samsung device . One of these vulnerabilities even exploits a flaw in the design of Samsung ’ s TizenStore app to hijack the software and deliver malicious code to a Samsung TV . Worse , the TizenStore app operates with the highest privileges on a Tizen device , so such a vulnerability is an even bigger cause of worry as Mr. Neiderman says Vulnerability-related.DiscoverVulnerability that you can update a Tizen system with any malicious code the hacker wants . The TizenStore does use authentication for making sure only authorized Samsung software gets installed , but a heap-overflow vulnerability allows for gaining control before the authentication kicks in . The researcher mentions that a lot of the Tizen code base is old and borrows from previous projects like Bada . But most of the vulnerabilities he found Vulnerability-related.DiscoverVulnerability were in new code specifically written for Tizen within the last two years . The vulnerabilities are described as “ mistakes programmers were making twenty years ago ” to indicate Vulnerability-related.DiscoverVulnerability that Samsung lacked basic code development and review practices for Tizen . When contacted , Samsung sent the researcher an automated email in response . Samsung ’ s current smartphone lineup is heavily dependent on Android , so these news shouldn ’ t necessarily impact your opinion of their Android smartphones in particular . But Samsung ’ s other avenues that involve Tizen are likely to invite hackers to explore and find Vulnerability-related.DiscoverVulnerability more of such zero-day vulnerabilities . There needs to be a higher priority on Tizen ’ s security if Samsung ever wants Tizen to bean OS for the internet of things .
