A stealthy hacking technique that could make it possible for attackers to access different components inside PCs made by the likes of Dell, HP and Lenovo still exists, five years after researchers first warned of it. Security researchers from Eclypsium, in findings published Tuesday, demonstrated how much of the firmware inside modern computers, such as webcams, USB hubs, trackpads and other internal hardware could be updated with “unsigned” code that’s not designed by the device vendor. That firmware, left unprotected, could provide outsiders with a gateway into more sensitive computer networks, all while PC customers implicitly trust their machine to safeguard their data. (The company only pointed to theoretical attacks, rather than an active, ongoing campaign against these devices.) “Firmware is meant to be invisible to the user, and so it’s not surprising that most people don’t pay attention to it,” said Eclypsium CEO Yuriy Bulgin. “However, these components make up […]
