Earlier we have seen IoT botnets like Mirai– one of the biggest IoT-based malware attacks last year and caused internet outrage by launching the massive DDoS attack against DynDNS provider and took down the major popular website.
Due to increase in the majority of Internet-Connected devices including Smart TVs, Refrigerators, Microwaves, Security Cameras, and printers, we have seen a major increase in hacking attempts on IoT and thus used as a weapon in massive cyber attacks.
Now, the senior penetration tester, IT forensic and security researcher at Thalwiler penetration testing specialist Oneconsult, had shown how the attacker can take complete control over a wide range of Smart TVs at once remotely.
Rafael Scheel provided the live hacking demonstration of the attack during a presentation at the European Broadcasting Union (EBU) Media Cyber Security Seminar, saying about 90 percent of the Smart TVs sold in the last years are potential to the attack.
Here Is The Video Demonstration:
The security researchers developed the exploit and provided the proof-of-concept(PoC) in the demonstration – to manipulate the HbbTV browser he used a uses a low-cost transmitter for embedding malicious commands into a rogue DVB-T (Digital Video Broadcasting — Terrestrial) signals.
Once prepared, the Smart TV can be used for various hacking purposes, whether for bitcoin mining, for DDoS attacks, or for eavesdropping on users.
Scheel also said, what is the best thing about the attack, once the victim TV is infected, the code works in the way that neither device reboots not factory resets would help the victim to safe its Smart TV from the malware.
The exploits have used two privilege escalation vulnerabilities in the web browsers, the attacker could remotely connect to TV over the Internet and allows an attacker to hijack the device.
The hack once again showed the risk of IoT devices. As the increase in IoT devices, hacking attempts are also being expanding.
