AMD processors sold between 2011 and 2019 are vulnerable to two side-channel attacks that can extract kernel data and secrets, according to a new research paper. In a paper [PDF] titled, "Take A Way: Exploring the Security Implications of AMD's Cache Way Predictors," six boffins - Moritz Lipp, Vedad Hadžić, Michael Schwarz, and Daniel Gruss, Clémentine Maurice, and Arthur Perais - explain how they reverse-engineered AMD's L1D cache way predictor to expose sensitive data in memory.

AMD is seeking to downplay side-channel attacks that can leak potentially sensitive data from its processors released between 2011 and 2019. AMD this weekend said it does not believe these are "New speculation-based attacks" and did not offer any mitigations: "We are aware of a new white paper that claims potential security exploits in AMD CPUs, whereby a malicious actor could manipulate a cache-related feature to potentially transmit user data in an unintended way," said AMD in a Saturday advisory.

It cannot be fixed without replacing the silicon, only mitigated, it is claimed: the design flaw is baked into millions of Intel processor chipsets manufactured over the past five years. Buried deep inside modern Intel chipsets is what's called the Management Engine, or these days, the Converged Security and Manageability Engine.

Garrison is using ARM processor chips to create a hardware defense against data breaches and malware. Instead of relying on endpoint protection or user training to improve security, the UK-based security company Garrison wants to use hardware to prevent malware infections and data breaches.

The vulnerability exists in Wi-Fi chips made by Cypress Semiconductor and Broadcom, the latter a chipmaker Cypress acquired in 2016. The affected devices include iPhones, iPads, Macs, Amazon Echos and Kindles, Android devices, and Wi-Fi routers from Asus and Huawei, as well as the Raspberry Pi 3.

Jetico, long-trusted pioneer in data encryption, announced support for Mac computers with a T2 security chip. With this update, BestCrypt Volume Encryption - Enterprise Edition becomes the industry's most comprehensive enterprise encryption software for Windows and macOS. "Native OS encryption tools might be an easy way to get started with data protection. Yet there's a critical limitation. Their security is bound to only some versions of a single operating system," states Jetico CEO, Michael Waksman.

To combat supply chain counterfeiting, which can cost companies billions of dollars annually, MIT researchers have invented a cryptographic ID tag that's small enough to fit on virtually any product and verify its authenticity. Wireless ID tags are becoming increasingly popular for authenticating assets as they change hands at each checkpoint.

More than a quarter century after its introduction, the failed rollout of hardware deliberately backdoored by the NSA is still having an impact on the modern encryption debate. Known as Clipper, the encryption chipset developed and championed by the US government only lasted a few years, from 1993 to 1996.
