China has banned U.S. chip maker Micron from selling its products to Chinese companies working on key infrastructure projects, citing national security risks. The development comes nearly two months after the country's cybersecurity authority initiated a probe in late March 2023 to assess potential network security risks.
Google is calling attention to a set of severe security flaws in Samsung's Exynos chips, some of which could be exploited remotely to completely compromise a phone without requiring any user interaction. The 18 zero-day vulnerabilities affect a wide range of Android smartphones from Samsung, Vivo, Google, wearables using the Exynos W920 chipset, and vehicles equipped with the Exynos Auto T5123 chipset.
Blocked by the British government from acquiring Newport Wafer Fab - Britain's largest chip factory - Nexperia has solicited the help of US law firm Akin Gump in the hopes of overturning the ban. Nexperia is a Netherlands-based company that was acquired in 2018 by China-based Wingtech Technology.
Attempts to reorganize supply chains to cut out China and foil its attempts to build a high-tech chip industry will be costly and may simply cause the Middle Kingdom to redouble its efforts, says memory maker Kioxia. Flores said China would likely retaliate against the recently announced US export controls by ramping up domestic investment in NAND as a long-term solution to its chip supply issues.
Security flaws have been identified in Xiaomi Redmi Note 9T and Redmi Note 11 models, which could be exploited to disable the mobile payment mechanism and even forge transactions via a rogue Android app installed on the devices. Specifically, the Israeli cybersecurity firm discovered that a trusted app on a Xiaomi device can be downgraded due to a lack of version control, enabling an attacker to replace a newer, secure version of an app with an older, vulnerable variant.
Intel has disclosed how it may be able to protect systems against some physical threats by repurposing circuitry originally designed to counter variations in voltage and timing that may occur as silicon circuits age. According to Intel, adding the TRC brings fault injection detection technology to the Converged Security and Management Engine, a part of the Platform Controller Hub chipset in Alder Lake.
Security analysts have found security issues in the payment system present on Xiaomi smartphones that rely on MediaTek chips providing the trusted execution environment that is responsible for signing transactions. Considering how common mobile payments and Xiaomi phones are, especially in Asian markets, the money pool hackers could tap into is estimated to be in the billions of U.S. dollars.
What is an APIC, and why do I need it? How can you have data that even the kernel can't peek at? What causes this epic failure in APIC? Does the ÆPIC Leak affect me? What to do about it? What's an APIC? How can you have data that even the kernel can't peek at?
A group of computer scientists has identified an architectural error in certain recent Intel CPUs that can be abused to expose SGX enclave data like private encryption keys. The bug affects recent Intel CPUs based on the company's Sunny Cove microarchitecture, the authors say.
The enterprise-grade Titan M security chip was custom built to help protect data. Derived from the same chip Google uses to protect its cloud data centers, it handles processes and information, such as passcode protection, encryption, and secure transactions in apps.
