Major vulnerabilities in the Realtek RTL8195A Wi-Fi module expose embedded devices used in a myriad of industries to remote attacks, researchers with automated device security platform provider Vdoo reveal. The low-power Wi-Fi module is designed for use in embedded devices, and is being used in a broad range of industries, including automotive, agriculture, energy, healthcare, industrial, and security.

Major vulnerabilities have been discovered in the Realtek RTL8195A Wi-Fi module that could have been exploited to gain root access and take complete control of a device's wireless communications. The Realtek RTL8195A module is a standalone, low-power-consumption Wi-Fi hardware module targeted at embedded devices used in several industries such as agriculture, smart home, healthcare, gaming, and automotive sectors.

D-Link announced their new COVR-X1870 Series Whole Home Mesh Wi-Fi 6 Systems, including multi-pack options that are all equipped with Wi-Fi 6 and mesh technology to provide faster speeds, greater capacity, and less network congestion for the modern device-dense smart home. With next generation speeds of up to 1.8 Gbps total, these Covr AX Wi-Fi 6 solutions are perfect for simultaneous 4K streaming, VR gaming, video calling, and keeping the smart home connected.

D-Link unveils their new 5GNR Wi-Fi 6 CPE device as well as announces availability of a new 5G Wi-Fi 6 Mobile Hotspot. "Our new CPE and mobile hotspot are evidence of D-Link's continued development in next-generation solutions for home and business users," said Raman Bridwell, vice president, products and services at D-Link Systems.

Networking vendor Ubiquiti has written to its customers to advise them of a possible leak of their personal information. "We recently became aware of unauthorized access to certain of our information technology systems hosted by a third-party cloud provider," the email opens, before adding: "We have no indication that there has been unauthorized activity with respect to any user's account."

CommScope announced it is expanding its industry leading Wi-Fi 6 home network gateway portfolio with the release of its NVG578LX 2.5G GPON Wi-Fi 6 residential gateway. The NVG578LX GPON home network gateway provides true gigabit speeds for the delivery of managed voice, video and data services.

You should always lock your computer when you walk away. I'm a firm believer in locking your computer when you step away from it for any amount of time.

Super-secure air-gapped computers are vulnerable to a new type of attack that can turn a PC's memory module into a modified Wi-Fi radio, which can then transmit sensitive data at 100 bits-per-second wirelessly to nearly six feet away. Noted air-gap researcher Mordechai Guri created the proof-of-concept attack and described it in a research paper released earlier this month under the auspices of Ben-Gurion University of the Negev, Israel's cybersecurity research center.

Covert Wi-Fi signals generated by DDR SDRAM hardware can be leveraged to exfiltrate data from air-gapped computers, a researcher claims. In a newly published paper, Mordechai Guri from the Ben-Gurion University of the Negev in Israel details AIR-FI, a new data exfiltration technique in which malware installed on a compromised air-gapped system can generate Wi-Fi signals that a nearby device intercepts and sends to the attacker, over the Internet.

In a newly released working paper [PDF], "AIR-FI: Generating Covert Wi-Fi Signals from Air-Gapped Computers," Guri, head of research and development at Ben-Gurion University of the Negev, Israel's Cyber-Security Research Center, describes a technique for turning DDR SDRAM buses into transmitters that can spew sensitive data. It's a method for sending data via Wi-Fi signals when the target device doesn't have Wi-Fi capability.
