Is it sensational? You are watching hackers behind tv watching you

This is not sensational. At the SyScan360 International Forward-Lacking Information Security Conference in Shanghai, British hackers stated that there are loopholes in the TV system standards that may affect hundreds of millions of TVs.

TV hacker will appear in SyScan360

The SyScan360 international forward-looking information security conference was officially held in China in 2012. This year is already the fifth year. This year's conference invited the famous British hacker, Adam Laurie, to bring the topic of television cracking.

“It will introduce the actual attacks on all British television stations that meet the criteria of “Freeview.” It will affect all digital TVs, just as we have previously turned off analog signals.” In a reporter e-mail interview, Adam Laurie stated that he had discovered A new loophole exists in the MHEG TV standard. Countries and regions currently adopting MHEG standards include Ireland, New Zealand, Australia and Hong Kong.

According to Adam Laurie, the loopholes have a huge impact. Not only will the latest smart TVs be affected, but in the past non-networked televisions will also be affected. Hackers can change the content of old-fashioned televisions, including pictures and sounds. TVs connected to the Internet can also allow viewers to see fake content, and other hardware devices on the same network as TVs can be attacked.

Experts believe that this type of attack is more "precise" than the hijacking of TV tower signals, because hackers may have succeeded before the relevant authorities started.

Adam Laurie said that now China is trying a similar system called HBBTV, and there are similar loopholes in the system. With the increasing popularity of interactive and Internet and smart TVs, all televisions in the world will encounter similar problems. Tens of millions or even hundreds of millions of televisions are currently affected. But if the problem is not solved, billions of televisions will eventually be affected.

Ten years ago, he used TV loopholes to "play bad" hotel systems.

Adam Laurie is an "old gun" hacker. Since 1997, he has been a senior member of DEFCON. He has a wide range of concerns in the security field. Magnetic stripe security, EMV credit card security, infrared security, radio frequency security, and even satellite security are all in him. Within the scope of the study.

Adam Laurie speaks at SyScan360

Adam Laurie has always been at the forefront of TV cracking. In 2005, at the Defcon Security Experts Conference, Adam Laurie demonstrated how to invade hotel systems through television. Finally, it includes the hotel housing rate, the name of the tenant, the bill, the location of the call and the time of stay, etc. Even Adam Laurie can use this loophole to find out what other people are watching, change the bills of drinks in the room, and follow them on the hotel's TV. They can also set up wake-up services and even check-out.

This major flaw caused the industry to exclaim, Adam Laurie said, as long as you carry laptops and USB TV tuner can be, stealing as much information, so that Adam Laurie also amazed.

"Hackers should continue to learn and practice, challenge their own understanding, so that he will gain more than expected." Adam Laurie claimed that when arriving in a different time zone, there is nothing to do in the middle of the night, but because of the jet lag can not sleep At the time, he usually plays with the hotel system. "Playing with the hotel system is a very fun and interesting thing. Skilled hackers must constantly temper their skills to keep them safe."

Smart TVs may be more widely attacked

According to Adam Laurie, given the broadcast nature and the lack of a return path, in reality, conventional home TVs are more difficult to protect. Internet TV IP services can be protected by strong cryptography and session management. However, because these TVs generally have access to the Internet, they are also vulnerable to widespread attacks. Security professionals must first discover these problems and then take practical actions to protect television and television viewers.

Adam Laurie is confident in SyScan 360's speech. Adam Laurie answers only two words: confidentiality for whether he will invade television during his stay in Shanghai.

This reporter learned that on November 24th, the 2016 SyScan360 International Forward-Lacking Information Security Conference sponsored by China's largest Internet security company 360 will be held in Shanghai. This will be the last security event in the domestic security circle. Topics covered include Mac OS, iOS, medical IoT device security, windows kernel security, latest browser attack technology, banking security, chip security, digital TV security, automotive safety, etc. Artificial intelligence security and the use of artificial intelligence to solve security issues Become the focus of this year's SysCan360.

Conversation with Adam Laurie:

1. As you all know, in 2005, at the Defcon Security Experts Conference, you demonstrated how to use television to invade hotel systems. The resulting information includes the hotel occupancy rate, the names of the guests, their bills, the location of the call and the time of stay. We want to know what is the best place for you to crack this time, or what can be achieved through cracking?

I must admit that this is completely beyond my expectation! Like many similar attacks, that attack started with small loopholes, but it was really surprising that I was able to steal so much information. When I arrived in a different time zone, I had nothing to do in the middle of the night, but I often played with the hotel system because of the time difference and I could not sleep. Playing with the hotel system is a very fun and interesting thing. Skilled hackers must constantly temper their skills in order to keep them afloat. Hackers should continue to learn and practice, challenge their own understanding, so that his gains will exceed expectations.

2. We understand that you will introduce actual attacks against all current British TV stations that meet the "Freeview" standard. This vulnerability exists in the MHEG standard (think Teletext for strutoids) and gives all data services including the BBC "red button service" power, so it affects all televisions, not just new smart TVs. Is it applicable to TV in other countries such as China?

The countries and regions currently adopting the MHEG standard are Ireland, New Zealand, Australia and Hong Kong. Hong Kong, China is the only region that speaks Chinese, but now China is experimenting with a similar system called HBBTV. I think there is such a system. Similar loopholes. With the increasing popularity of interactive and connected/smart TVs, eventually all TVs around the world will soon encounter similar problems.

3. According to your estimation, how many TVs will this loophole affect?

At present, I think there will be tens of millions or even hundreds of millions of televisions affected. But if the problem is not solved, billions of televisions will eventually be affected.

4. At present, there are many televisions on the Chinese market, including digital television, analog television, and a number of Internet TVs produced by new Internet companies. Some are based on network transmission signals, and some are based on traditional wired transmission signals. Can they be cracked? Do you think that the new danger of relying on the network to transmit signals to the TV is more than that of traditional TV?

Traditional terrestrial television is more difficult to protect given broadcast characteristics and lack of return paths. Internet IP services can be protected by strong cryptography and session management, but as mentioned earlier, because they are networked, they are also vulnerable to widespread attacks. I think we must first find the problems of these two systems, and then take practical actions to provide them with appropriate protection.

5. In the near future, the United States had a disconnection incident on a well-known Internet site. The media claimed that it was related to an attack on a smart hardware vulnerability. In your opinion, how does intelligent hardware affect Internet security?

The use of IoT devices as attack platforms has brought revolutionary changes. The real problem is that most of these devices are unsupervised and never updated. Once field loopholes are deployed, they will remain active threats for the rest of their life.

6. Are you a person who likes pranks? Would you really come to Shanghai to choose a hotel to crack some TV sets?
