Researchers find new way for Alexa and Google Voice to phish users

What's happening: With smart speakers, it's tough to tell if an application is still open after it stops speaking. Researchers have, over the years, discovered several ways to force smart speakers to stop talking for a few minutes — making it appear as though an app has closed — before sending a message requesting a user to reenter their password. At this point, it seems like it's Google and not an app asking for the info.

• In the SRLabs case, adding the "�" character to various commands allowed programmers to keep an app open much longer than it should be.
• Smart speakers frequently have a light or other notification to show that an app is still running. That's useful if a user thinks to look for it and is nearby, but easy to overlook during a hectic day.
