Researchers discover battery-free technology that harvests power from radio and Wi-Fi signals for low-powered devices
Researchers at the National University of Singapore (NUS) have found a new type of energy harvesting module which extracts energy from radio frequencies (RF).Typically called ‘waste energy’, these modules convert the RF signals into DC voltage which can be used by low-powered devices. The radio frequency energy harvesting modules could reduce the dependency on batteries […]
Can DDR5 Motherboards Use DDR4 RAM?
When it comes to upgrading or building a computer, one common question arises: can DDR5 motherboards use DDR4 memory? The short answer is no. DDR5 and DDR4 memories are not interchangeable, primarily due to differences in physical design, pin configuration, and voltage requirements.

New PIXHELL acoustic attack leaks secrets from LCD screen noise
A novel acoustic attack named ‘PIXHELL’ can leak secrets from air-gapped and audio-gapped systems, and without requiring speakers, through the LCD monitors they connect to. In a PIXHELL attack, malware modulates the pixel patterns on LCD screens to induce noise in the frequency range of 0-22 kHz, carrying encoded signals within those acoustic waves that can […]
New RAMBO attack steals data using RAM in air-gapped computers
A novel side-channel attack dubbed “RAMBO” (Radiation of Air-gapped Memory Bus for Offense) generates electromagnetic radiation from a device’s RAM to send data from air-gapped computers. Air-gapped systems, typically used in mission-critical environments with exceptionally high-security requirements, such as governments, weapon systems, and nuclear power stations, are isolated from the public internet and other networks to […]
