Comcast Testing Encrypted DNS While Lobbing Against It

Encrypted DNS (either DoH or DoT) has become a political hotbutton.  Recently Vice reported that Comcast is spending hundreds of thousands of dollars lobbying against it.  Mozilla is writing to Congress saying that what Comcast is saying is not true and most interestingly, Comcast is testing its own DoT and DoH services.  Apparently, what is important is that they can continue to sell your data and not much else.  Source: Vice

Smart Speakers Can Be Hacked By Laser

Researchers have DEMONSTRATED the ability to talk to your Alexa or Siri by silently pointing a laser at the microphone and modulating the laser so that the microphone thinks you are talking to it.  This will work through a window.  In one test they were able to control an iPad from 33 feet,  In another test, they were able to control a device from over 300 feet away.

The amount of mischief this could potentially cause is large.

The temporary solution is to hide your smart speaker so that no one can point a laser at it from outside your home, for example, and tell it to buy stuff or unlock the door or whatver.  Source: Wired
