Security researchers have developed a new malicious’skill’ for Amazon’s voice assistant Alexa that can turn your Amazon Echo into a full-fledged spying device. The malicious skill, if installed, immediately gets activated in the background after a user says “Alexa, open calculator” Amazon has already addressed the problem by scanning for malicious skills that “silent prompts or that listen for unusual lengths of time” and kicking them out of their official store. The hack could allow attackers to keep the second session active for spying on users while ending the first when user interaction get overs.
