Chromecast Hack Promotes a YouTube Channel

This is embarrassing for Google! It’s Chromecast is being taken over in a hack that permits hackers to display content on user’s TVs!

From Slashdot: “In what is being referred to as CastHack, hackers j3ws3r and HackerGiraffe are promoting Felix ‘PewDiePie’ Kjellberg by forcing TVs to display a message encouraging people to subscribe to his YouTube channel. ‘The hack takes advantage of a router setting that makes smart devices, like Chromecasts and Google Homes, publicly viewable on the internet,’ reports The Verge. ‘The attackers are then able to gain control of the devices and broadcast videos on a connected TV.’ From the report:

A website for the attack claims to count the number of TVs forced to show the PewDiePie message and currently says more than 3,000 have been affected. While it’s not clear that this is an accurate number (it has reset several times), a number of people posted on Reddit that the video had appeared on their TV. Google tells The Verge it has received reports from people who had ‘an unauthorized video played on their TVs via a Chromecast device,’ but said the issue was the result of router settings. Both HackerGiraffe and Google told The Verge the best way for affected users to fix the issue is to turn off Universal Plug and Play (UPnP) on their routers.

The two hackers said they were behind a hack in November that forced printers around the world to print out sheets of paper telling people to subscribe to PewDiePie.”
