Washington University in St. Louis: ‘Surfing attack’ hacks Siri, Google with ultrasonic waves

Washington University in St. Louis: ‘Surfing attack’ hacks Siri, Google with ultrasonic waves. “Attacks on cell phones aren’t new, and researchers have previously shown that ultrasonic waves can be used to deliver a single command through the air. However, new research from Washington University in St. Louis expands the scope of vulnerability that ultrasonic waves pose to cellphone security. These waves, the researchers found, can propagate through many solid surfaces to activate voice recognition systems and — with the addition of some cheap hardware — the person initiating the attack can also hear the phone’s response.”

The Verge: AI translation boosted eBay sales more than 10 percent

The Verge: AI translation boosted eBay sales more than 10 percent. “We often hear that artificial intelligence is important for economic growth, and while that claim makes intuitive sense, there isn’t a lot of hard data to back it up.

WUSTL: Using Twitter may increase food-poisoning reporting

Twitter communications between the public and the proper government authorities could improve foodborne illness reporting as well as the steps that follow, according to a new study from the Brown School at Washington University in St. Louis.”
