Android Ransomware Hits Smart TVs (trendmicro.com)

Reader Trailrunner7 writes: Security researchers have discovered a variant of the FLocker Android ransomware that not only infects mobile devices, but also can infect smart TVs running certain versions of the operating system. FLocker ransomware has been active for more than a year now, and it is many ways a typical piece of mobile ransomware. It is designed to scare victims into paying a ransom -- $200 in this case -- by locking the infected device and throwing up a screen that accuses the victim of some fictitious crime. The ransomware doesn't appear to encrypt files on an infected device, but it locks the screen so the user can't open any other apps or take any other actions until paying the ransom.

Researchers at Trend Micro said they have seen various versions of FLocker over the last year and the activity level of the ransomware has varied. The newest version of the malware, however, includes the ability to infect art TVs, many of which run Android.

    This exploit puts software on Android systems in such a way that the usual install path doesn't see it. It's as if were the system capable of asking, "Are you new here?" the malware would say. "No, I've been here all along." and the system would be like, "Okay, then... carry on."

      Switching powers supplies, reactance and the electric grid.

      Old school power supplies are resistive, they draw a little less power when the line voltage drops,

      Switching power supplies have complex reactance. When the voltage drops, they draw higher current.

      When the grids reactance as a whole stops being mostly resistive, the grid goes unstable. The higher current draw further pulls down voltage, which pulls more current...

      The choices are smart devices that know not to draw higher current (sometimes) or maintaining 51% of the load as resistive.

    That's not an option with many new TVs: they require network connectivity or else they won't even work as a TV or display monitor.

    This is probably a good reason to buy your TV from Walmart actually: it's trivially easy to throw stuff back in the box (poorly) and get a full refund at your local Walmart. With Amazon, they'll probably require you to pay for return shipping costs.

    I would be extremely surprised if a tv did this, as its a good way to get returns. Because there are many reasons why a network connection can't be made.

    First, WiFi may require a password - not just a wpa key, but a captive portal. Second, Ethernet may not be available. Third, the user may just want to get something on the screen in a hurry (perhaps they bought the first TV they saw to replace a broken one for the big game). Finally, internet may not be available, period (e.g., trade show).

    Or the user wants to have a TV to watch and wait for their kids to come over on the weekend to set up the wifi stuff.

    You're confused. Wireless is for people that have old houses that are the equivalent of an old man with a bad prostate. Wireless is what's for people that can't or won't get with the times.

    I've been unfortunate enough to garner a few IoT devices, including a Samsung Smart TV.

    >32" is out of the main stream for computer monitors. If you search on Amazon, you get a bunch of oddball shit, about half of which is priced exorbitantly.

    Which one of these "reasonably priced" models do you own? Whichever one, that wasn't exactly a savvy purchase. They are more expensive than a 2016 4K TV, and don't have any of the image enhancement features of modern TVs (upscaling, local dimming, etc) and aren't newer display technology like VA, OLED, IPS.

    Only one of the 10+ models listed has a review, and only one review. Big sellers I guess.

    There is one model that's listed at ~$1k, the rest are >$2k many of which are $5k+. The $1k model is a plain old TN LCD display (hello, 1997). The first listing if $2.2k and is also a plain old TN LCD.
