Researchers demonstrate acoustic levitation of a large sphere

When placed in an acoustic field, small objects experience a net force that can be used to levitate the objects in air. In a new study, researchers have experimentally demonstrated the acoustic levitation of a 50-mm (2-inch) solid polystyrene sphere using ultrasound—acoustic waves that are above the frequency of human hearing. The demonstration is one Read more about Researchers demonstrate acoustic levitation of a large sphere[…]

DiskFiltration: sending data using Covert Hard Drive Noise

‘DiskFiltration,’ a covert channel which facilitates the leakage of data from an air-gapped compute via acoustic signals emitted from its hard disk drive (HDD). Our method is unique in that, unlike other acoustic covert channels, it doesn’t require the presence of speakers or audio hardware in the air-gapped computer. A malware installed on a compromised Read more about DiskFiltration: sending data using Covert Hard Drive Noise[…]

How the father of the World Wide Web is trying to decentralise it.

Facebook, Google, eBay, and others own vast swaths of Web activity and have unprecedented power over us, inspiring an effort to re-decentralize the Web.[…] Berners-Lee’s new project, underway at his MIT lab, is called Solid (“social linked data”), a way for you to own your own data while making it available to the applications that Read more about How the father of the World Wide Web is trying to decentralise it.[…]

MS Secureboot has a golden key – which has been hacked.

secureboot is a part of the uefi firmware, when enabled, it only lets stuff run that’s signed by a cert in db, and whose hash is not in dbx (revoked). As you probably also know, there are devices where secure boot can NOT be disabled by the user (Windows RT, HoloLens, Windows Phone, maybe Surface Read more about MS Secureboot has a golden key – which has been hacked.[…]

Failed HUD Helmet Maker Skully Spent Funding On Strippers And Exotic Cars: Lawsuit

In 2014, San Francisco tech startup Skully raised hype and money to build a Tony Stark-style digitally augmented motorcycle helmet. Almost $2.5 million later, the company’s shutting down. Now a lawsuit from within the company gives us some hints as to why: founders allegedly blew the R&D money on lap dances and fast cars.

Stratux: DIY ADS-B aircraft receiver on Raspberry Pi

Hello! Stratux is a homebuilt ADS-B In receiver for pilots. It’s easy to assemble from inexpensive, off-the-shelf hardware, and probably already works with your electronic flight bag (EFB) of choice. Even better, if you’re so inclined, the software is open-source and hackable so you can build the system that’s right for you.

Thieves can wirelessly unlock up to 100 million Volkswagens (and other brands by VW), each at the press of a button

The hack can be used by thieves to wirelessly unlock as many as 100 million VW cars, each at the press of a button. Almost every vehicle the Volkswagen group has sold for the past 20 years – including cars badged under the Audi and Skoda brands – is potentially vulnerable, say the researchers. The Read more about Thieves can wirelessly unlock up to 100 million Volkswagens (and other brands by VW), each at the press of a button[…]
