A group of researchers from the University of Florida has published a study on a type of attack using Qi wireless chargers, which they’ve dubbed VoltSchemer. In the study, they describe in detail how these attacks work, what makes them possible, and what results they’ve achieved. In this post, first we’ll discuss the researchers’ main findings. Then we’ll explore what it all … [Read more...] about VoltSchemer: attacks on wireless chargers through the power supply

Creating Wireless Signals with Ethernet Cable to Steal Data from Air-Gapped Systems
A newly discovered data exfiltration mechanism employs Ethernet cables as a "transmitting antenna" to stealthily siphon highly-sensitive data from air-gapped systems, according to the latest research. "It's interesting that the wires that came to protect the air-gap become the vulnerability of the air gap in this attack," Dr. Mordechai Guri, the head of R&D in the Cyber … [Read more...] about Creating Wireless Signals with Ethernet Cable to Steal Data from Air-Gapped Systems
Having Confidence in Your Wireless Security
As each day passes, wireless security becomes even more critical to the day-to-day operations of organizations. Several factors contribute to the growing need for reliable security. With the introduction of Wi-Fi 6, many organizations are shifting from a primarily wired infrastructure to one that focuses on worker mobility through wireless connectivity. While the CAPEX and OPEX … [Read more...] about Having Confidence in Your Wireless Security
