Hackers seize control of more than 70,000 Chromecasts, promote YouTuber PewDiePie
July 12, 2025
A pair of hackers have hijackedGoogle Chromecastsand called on their owners to follow YouTubers PewDiePie. The hackers, known as HackerGiraffe and j3ws3r, are estimated to have accessed more than 70,000 devices so far with the exploit, according to theCastHack websitethe hackers launched (viaThe Verge).
The exploit targets a router setting that makes smart home products viewable on the internet. With Chromecast access gained, the hackers can “remotely play media on your device, rename your device, factory reset or reboot the device, force it to forget all Wi-Fi networks, force it to pair to a new Bluetooth speaker/Wi-Fi point, and so on,” it said on CastHack. Folks have also taken toRedditto talk about their hacked devices.
Google has said itisn’t to blamefor the attack, but that it’s the fault of the individuals’ routers. Both Google and HackerGiraffe have said the best way to fix the issue is to turn off “Universal Plug and Play (UPnP)” in their routers’ settings, saidThe Verge.
Despite advocating the YouTube stars’ pages, HackerGiraffe said promoting PewDiePie wasn’t the main purpose of the attack. Rather, the hacker said it was to expose the product’s vulnerabilities and remind Google of security flaws.
Reportedly, the hackers don’t harvest or save any information accessed during the attack, they just rename devices. Still, well-meaning or not, seeing the hack message pop up on a TV must be a very unsettling experience for the people affected.
