Researchers figure out how to read what people are typing during a Zoom call using shoulder movements. They claim to be able to read slight pixel shifts on high-definition video around someone s shoulders and upper arms to see if their movements were headed either north, south, east or west. From there, the team could map keystrokes on a QWERTY keyboard to make inferences about the text. A recent study warns malicious actors might use the technique to decipher personal passwords and proprietary business information.
