ASCII.jp Sudden intimidation letter on TV!Experience the threat to sneaking into your home
Suddenly, the threat and countdown to "pay a fine" on the TV screen!What if the same thing happens at your home!?
Try a little early liver with ransomware!?
The most scary thing about cyber attacks is that important data stored on a computer or smartphone disappears.If you lose, you will never get the data you need at work, as well as the memories of your family or videos.
Ransomware, which uses important data as a hostage and demands money, is a sneaky crime.In 2017, the damage caused by the ransomware "Wannacry" was rampant around the world and became a big topic.Recently, a variant of ransomware called "PETYA", which makes it impossible to launch a personal computer, is damaged in Europe and the United States.
PCs and smartphones can be protected with security products, but ...
Ransomware measures are progressing in security on personal computers and smartphones, but it is said that the threat of ransomware has been stolen in other devices that lead to networks in the home (in general).Katsuyuki Wada, who is in charge of consumer product marketing at the trend micro who heard the story.
However, I do not hear that the surroundings are infected with ransomware, and I am not sure what happens if they are actually infected.Furthermore, even if a TV or printer that does not contain so much data is targeted, it is true that the damage will not come close.
This time, with the cooperation of the trend micro, I experienced a demonstration when a home device was infected with ransomware.In conclusion, it was a little earlier, a bad heart than I thought.
Continuing from the last time, Mr. Katsuyuki Wada, Consumer Velopment Department, Consumer Product Marketing Division, Product Marketing Division, Corporation, and Katsuyuki Wada.
Smart TV was taken over without any warning!
Ransomware damage to smart TV, which had been infected in 2016.First, experience the demonstration.
In front of you is a very ordinary smart TV.You can watch movies and dramas downloaded from the Internet on -demand, and enjoy the content of the video distribution site by streaming.In this demonstration, the router connected by this smart TV has a vulnerability and is pierced.
The DNS setting will be connected to the router whose DNS setting has been changed to see the content of the net.It doesn't seem to be particularly unusual on the surface, but when communication starts, you will be guided to an illegal website and will be downloaded without unauthorized programs.One icon is increasing."Music" icon that should not exist.This is a ransomware trigger.
"What kind of content has increased? What kind of content is there?"
Although it is a smart TV function selection screen that has no change, ransomware has already been infiltrated.As soon as I clicked on the "music" icon that increased suddenly ...
A meaningful countdown on the whole screen and "Warning! The equipment you use has been locked / Please pay in time to release / if you do not respond, you will be notified to the court."letter.To be honest, "I want to notify the court here!"I thought
If you notice it, the icon has changed to a squid ...!
When I returned to the front screen in a hurry, it was already late.The display of other icons gradually turns into a mysterious squid icon, and no matter what you do, the intimidation screen is displayed and you can't do anything.
Once the power is turned off or reset, it looks like it has returned to the normal screen, but after a while it will return to the original squid icon.It's completely up!
By the way, if you do not press the trigger icon, it is not okay, and the smart TV is infected at the time of connecting to the infected router, so if you leave it alone, the icon will change or locked.It will be closed (even if it is okay if you do not press it, it is over if the operation is wrong).
