A Marco Rubio Impostor is Using AI Voice To Call High-Level Officials

2 months 1 week ago
An impostor pretending to be Secretary of State Marco Rubio contacted foreign ministers, a U.S. governor and a member of Congress by sending them voice and text messages that mimic Rubio's voice and writing style using AI-powered software, Washington Post reported Tuesday, citing a senior U.S. official and a State Department cable. From the report: U.S. authorities do not know who is behind the string of impersonation attempts but they believe the culprit was probably attempting to manipulate powerful government officials "with the goal of gaining access to information or accounts," according to a cable sent by Rubio's office to State Department employees. Using both text messaging and the encrypted messaging app Signal, which the Trump administration uses extensively, the impostor "contacted at least five non-Department individuals, including three foreign ministers, a U.S. governor, and a U.S. member of Congress," said the cable, dated July 3. The impersonation campaign began in mid-June when the impostor created a Signal account using the display name "Marco.Rubio@state.gov" to contact unsuspecting foreign and domestic diplomats and politicians, said the cable.

Linux Kernel 6.14: A Leap Forward in Intel and AMD CPU Support

2 months 1 week ago
by George Whittaker

Released on March 24, 2025, Linux Kernel 6.14 introduces significant enhancements for Intel and AMD processors, focusing on performance, power efficiency, and hardware compatibility. These updates are particularly beneficial for users leveraging the latest CPU architectures and AI-driven workloads.

Intel CPU Enhancements Support for Upcoming Architectures

Linux 6.14 extends support to Intel's forthcoming Panther Lake CPUs, incorporating thermal driver support for improved power efficiency and enabling Ultra-High Bit Rate (UHBR) modes via DisplayPort on Thunderbolt's Alt-Mode. This advancement allows for 10G and 20G UHBR modes, enhancing display capabilities for devices equipped with Xe3 graphics.

Additionally, preparations for Intel's Clearwater Forest server processors are underway, with the inclusion of EDAC (Error Detection and Correction) driver support and readiness of the Turbostat tool for monitoring.

Performance and Virtualization Improvements

The kernel introduces Translation Lookaside Buffer (TLB) flushing scalability optimizations, reducing overhead during context switches and improving overall system performance. Enhancements to the x86 Kernel-based Virtual Machine (KVM) also contribute to better virtualization support, benefiting environments that rely on virtual machines.

AMD CPU Enhancements Introduction of AMD XDNA Driver

A notable addition in Linux 6.14 is the AMD XDNA driver, providing support for AMD's Neural Processing Units (NPUs) integrated into Ryzen AI processors. This driver facilitates AI workloads, such as machine learning applications, by enabling efficient execution of tasks like convolutional neural networks and large language models.

Power Management and Performance Tweaks

The AMD P-State driver receives updates, including dynamic ranking of preferred CPU cores and defaulting to the 'balance_performance' Energy Performance Policy (EPP) on Ryzen and EPYC processors. These changes aim to optimize power consumption without compromising performance.

Furthermore, encryption performance sees a 2-3% boost for AES-GCM and AES-XTS standards on Zen 4 and Zen 5 processors, enhancing data security operations.

Broader Implications

Beyond CPU-specific enhancements, Linux 6.14 introduces the NTSYNC driver, improving compatibility and performance for Windows games emulated via Wine and Proton. The kernel also expands support to accommodate up to 4,096 CPU cores, doubling the previous limit and catering to high-performance computing environments. Additionally, improvements in suspend/resume functionality enhance power management for various devices.
