Intel Downfall (Gather Data Sampling) vulnerability impacts AVX2/AVX-512 workloads

After vulnerabilities like Spectre and Meltdown were discovered in 2018, Intel processors have more vulnerabilities with the Downfall attacks that target the Gather instruction part of AVX2/AVX-512 and impact 6th generation Skylake up to 11th generation Tiger Lake processors introduced as far back as 2014. It does not affect more recent processors, and as somebody who has just purchased a laptop based on a 13th Raptor Lake processor, I guess I can breathe a sigh of relief until the next vulnerability is discovered, but people using hardware with older Intel processors will have to update the OS and suffer from a performance impact, at least for tasks leveraging AVX2 or AVX-512. The website about the Downfall vulnerability explains: Downfall attacks targets a critical weakness found in billions of modern processors used in personal and cloud computers. This vulnerability, identified as CVE-2022-40982, enables a user to access and steal data from […]

FCC and NIST unveils the Cyber Trust Mark, a voluntary US IoT security label

Representatives of the Federal Communications Commission (FCC) and the National Institute of Standards and Technology (NIST) have recently unveiled a U.S. national IoT security label at the White House called the “U.S. Cyber Trust Mark” to inform consumers about the security, safety, and privacy of a specific IoT and Smart Home device. IoT security has been a problem for years with routers shipping with telnet enabled with default usernames and passwords, vulnerabilities in SDKs, unencrypted passwords transmitted over the network, millions of devices with older microcontrollers without built-in hardware security features, etc… There have been industry efforts to solve this such as the Arm PSA initiative, as well as regulations to prevent default usernames/passwords in new devices, but nothing about IoT security that can help a consumer find out if a device is supposed to be secure or not. The Cyber Trust Mark is supposed to address this issue. The […]

Diabolic Drive is a penetration testing USB key with 64GB storage, ESP8266 and ATmega32U4 microcontrollers

Diabolic Drive may look like a 64GB USB flash drive and show as such when you insert it into your computer, but it’s actually a wireless keystroke injection tool with a Microchip ATmega32U4 8-bit AVR microcontroller and an Espressif Systems ESP8266 WiFi SoC. Egypt-based UNIT 72784 says their cyber security tool enables Red Teaming – the practice of rigorously identifying an attack path to breach a device’s security – as it behaves like a flash drive while being able to deploy keyboard strokes wirelessly through the ESP8266 WiFi MCU. Diabolic Drive specifications: MCUs Microchip ATmega32U4 microcontroller @ 16 MHz (5V) acting as a Serial Bridge Espressif Systems ESP8266EX microcontroller @ 160 MHZ (3.3V) with WiFi 4 support ATmega32U4 and ESP8266 are connected via Serial and I2C protocols thanks to an LDO regulator.

NEWRACOM NRC7394 WiFi HaLow SoC delivers higher power efficiency and cost-effectiveness

NEWRACOM has just introduced the NRC7394 Wi-Fi HaLow Arm Cortex-M3 SoC with higher power efficiency and lower cost than the previous generation NRC7292 Cortex-M3/M0 HaLow SoC and available in a 6x6mm package. I first wrote about the 802.11ah standard in 2014. Also known as the WiFi HaLow (consumers name), it operates in the 900 MHz band, offers a longer range and lower power consumption for items like IP cameras, and the first products came to market in 2021. I was expecting a flood of new WiFi HaLow devices in 2022 in my year 2021 round-up and it was not exactly a prescient prediction as it never happened. But maybe the new NRC7394 SoC will help make WiFi HaLow devices more popular by lowering the costs and further improving battery life. NEWRACOM NRC7394 key features: CPU – Arm Cortex-M3 core @ 32 MHz for IEEE 802.11ah WLAN and application Connectivity Full […]
