Hackers Can Turn Everyday Speakers Into Acoustic Cyberweapons

Speakers are everywhere, whether it’s expensive, standalone sound systems, laptops, smart home devices, or cheap portables. And while you rely on them for music or conversation, researchers have long known that commercial speakers are also physically able to emit frequencies outside of audible range for humans. At the Defcon security conference in Las Vegas on Sunday, one researcher is warning that this capability has the potential to be weaponized.

It’s creepy enough that companies have experimented with tracking user browsing by playing inaudible, ultrasonic beacons through their computer and phone speakers when they visit certain websites. But Matt Wixey, cybersecurity research lead at the technology consulting firm PWC UK, says that it’s surprisingly easy to write custom malware that can induce all sorts of embedded speakers to emit inaudible frequencies at high intensity, or blast out [...]  read more

Ninja calls out Twitch after his dormant channel highlights porn

Needless to say, Ninja saw a number of problems with the move. It’s not just that Twitch effectively replaced his presence with recommendations, something he said wasn’t true of “any other” channel, it’s that it was tarnishing his brand. Kids could have seen this material, and he didn’t have any control over it. While Ninja apologized, he also stressed that he was trying to get rid of the promotions, if not remove the Twitch channel altogether.

We’ve asked Twitch for comment.

Whatever its response, this isn’t a great look for the service. It was no surprise that Ninja’s stream would scale back (Twitch partners aren’t allowed to stream on rival services), many only expected it to remain idle, not become a billboard for other broadcasters. It certainly underscores the significance of Ninja’s switch. His leap to Mixer represented a competitive blow, and Twitch clearly wasn’t happy about it.

Milano piace per film e spot: Galleria, Duomo e la Scala sono i set sempre più richiesti

Milano è un set sempre più richiesto da cinema, tv e per servizi fotografici. Il Comune di Milano nel 2018 ha rilasciato 717 autorizzazioni (erano 342 nel 2010) e anche per i primi sette mesi del 2019 si conferma il trend, con 462 richieste.

Watch a Drone Take Over a Nearby Smart TV

For all the focus on locking down laptops and smartphones, the biggest screen in millions of living rooms remains largely unsecured, even after years of warnings. Smart TVs today can fall prey to any number of hacker tricks—including one still-viable radio attack, stylishly demonstrated by a hovering drone.

At the Defcon hacker conference today, independent security researcher Pedro Cabrera showed off in a series of hacking proofs-of-concept attacks how modern TVs—and particularly Smart TVs that use the internet-connected HbbTV standard implemented in his native Spain, across Europe, and much of the rest of the world—remain vulnerable to hackers. Those techniques can force TVs to show whatever video a hacker chooses, display phishing messages that ask for the viewer’s passwords, inject keyloggers that capture the user’s remote button presses, and run cryptomining software. All of those attacks stem from the general lack of authentication in TV networks’ communications, [...]  read more
