To search out the weaknesses within the sensible speaker programs, the researchers from SRLabs created 4 apps for Alexa and 4 for Google House, all of which handed the protection vetting processes of each corporations. Seven of those apps posed as easy horoscope apps and one posed as a random quantity generator.
How The Apps Spied On Customers
