Researchers with the University of Michigan and the University of Electro-Communications (Tokyo) have devised a new technique, called “light commands,” to remotely hack popular voice assistants, such as Amazon Alexa, Apple Siri, Facebook Portal, and Google Assistant.

The “light commands” attack exploits a design flaw in the smart assistants microelectro-mechanical systems (MEMS) microphones. MEMS microphones convert voice commands into electrical signals, but researchers demonstrated that they can also react to laser light beams.

The researchers demonstrated how an attacker can inject arbitrary audio signals to the target microphone by aiming an amplitude-modulated light at the microphone’s aperture.

Security researcher Avinash Jain discovered more than 8,000 Google Calendars exposed online, that were indexed by the Google search engine.

The issue isn’t new, however users may not be aware of it. It occurs when users make the Google calendar public.

“While this is an intended setting by the user and intended behavior of the service,” Jain says, “the main issue here is that anyone can view any public calendar by making a single Google search query, and without the calendar link being shared with them.”

Users should review their calendar sharing options – see https://support.google.com/a/answer/60765?hl=en.
