As Frank Yeary retires from Intel, the company picks an engineer to chair its board — Intel Foundry governance issues to be resolved, and looking back at the Yeary years

(Latest from Tom's Hardware / 2026-03-05 18:14)

Intel's board of directors is appointing Dr. Craig H. Barratt, a semiconductor engineer and former Intel executive, as its new independent chair, effective May 13. He succeeds Frank D. Yeary, a finance veteran who is retiring from the board after serving since 2009 and as chair since 2023.

This change consolidates authority around Barratt and CEO Lip-Bu Tan to focus on scaling Intel's U.S. R&D, manufacturing, and its foundry business. Yeary's tenure as chair oversaw a period of significant financial losses and included consequential actions, such as orchestrating the removal of former CEO Pat Gelsinger and leading a board refresh to add directors with technology backgrounds.

China's top chip execs claim ASML alternative 'small, fragmented, and weak' — Chinese industry titans call for national effort to invest in advanced chipmaking tools

(Latest from Tom's Hardware / 2026-03-05 18:09)

Senior Chinese semiconductor executives from major firms like SMIC and YMTC have publicly stated that China's domestic chip equipment industry is too "small, fragmented, and weak" to overcome U.S. export restrictions. They called for a consolidated national effort to develop alternatives in key areas like EUV lithography and EDA software, criticizing fragmented funding for dispersing resources without results.

The executives highlighted a significant technology gap, noting China's most advanced domestic lithography tool is comparable to ASML's 2008-era technology for 32nm processes. They acknowledged that replicating ASML's EUV dominance, built on a vast supply chain and decades of data, presents a monumental challenge that cannot be quickly solved through reverse engineering.

China's upcoming national Five-Year Plan is expected to prioritize lithography and EDA development, with a new state-backed fund directing billions toward these sectors. Despite the call for unity and increased investment, the technical hurdles to achieving sub-10nm chip production domestically remain substantial and will require many years of development.

Main topics: China's semiconductor industry challenges, call for national consolidation in chipmaking tools, technology gaps in lithography and EDA, impact of U.S. export controls, and state planning and funding for semiconductor self-sufficiency.

Google says half of all zero-days it tracked in 2025 targeted buggy enterprise tech

(TechCrunch / 2026-03-05 18:06)

A new Google report reveals a record high of 48% of tracked zero-day vulnerabilities in 2023 targeted enterprise technologies, with half of those exploiting the security and networking devices designed to protect corporate networks. Hackers frequently targeted products from vendors like Cisco, Fortinet, Ivanti, and VMware, exploiting common flaws to breach defenses.

The remaining enterprise zero-days involved other software, such as Oracle's E-Business Suite, which was exploited in a campaign stealing HR data from major organizations. The other 52% of zero-days affected consumer products from companies like Microsoft, Google, and Apple, primarily in operating systems.

The report also noted a shift, with more zero-days attributed to commercial surveillance vendors selling hacking tools to governments than to traditional state-backed espionage groups.

Main topics: Enterprise cybersecurity threats, zero-day vulnerabilities, targeted vendors and attack methods, consumer software vulnerabilities, the rise of commercial surveillance vendors.
