Apple Inc is to release a patch for the Safari Web browser on its iPhones, iPads and Macs within days, it said on Thursday, after major chipmakers disclosed flaws that leave nearly every modern computing device vulnerable to hackers.
On Wednesday, Alphabet Inc’s Google and other security researchers disclosed two major chip flaws, one called “Meltdown” affecting only Intel Corp chips and one called “Spectre” affecting nearly all computer chips made in the past decade.
The news sparked a sell-off in Intel’s stock as investors tried to gauge the costs to the chipmaker.
In a statement on its Web site, Apple said all Mac and iOS devices are affected by both Meltdown and Spectre, but added that the most recent operating system updates for Mac computers, Apple TVs, iPhones and iPads protect users against the Meltdown attack and do not slow down the devices, and Meltdown does not affect the Apple Watch.
As Macs and iOS devices are vulnerable to Spectre attacks through code that can run in Web browsers, Apple said it would issue a patch to its Safari browser for those devices “in the coming days.”
Shortly after the researchers disclosed the chip flaws on Wednesday, Google and Microsoft Corp released statements telling users which of their products were affected.
Google said users of Android smartphones — more than 80 percent of the global market — were protected if they had the latest security updates.
Apple remained silent for more than a day about the fate of the hundreds of millions of users of its iPhones and iPads.
Ben Johnson, cofounder and chief strategist for cybersecurity firm Carbon Black, said the delay in updating customers about whether Apple’s devices are at risk could affect Apple’s drive to get more business clients to adopt its hardware.
“Something this severe gets the attention of all the employees and executives at a company, and when they go asking the IT [information technology] and security people about it and security doesn’t have an answer for iPhones and iPads, it just doesn’t give a whole lot of confidence,” Johnson said.
DECOUPLING? In a sign of deeper US-China technology decoupling, Apple has held initial talks about using Baidu’s generative AI technology in its iPhones, the Wall Street Journal said China has introduced guidelines to phase out US microprocessors from Intel Corp and Advanced Micro Devices Inc (AMD) from government PCs and servers, the Financial Times reported yesterday. The procurement guidance also seeks to sideline Microsoft Corp’s Windows operating system and foreign-made database software in favor of domestic options, the report said. Chinese officials have begun following the guidelines, which were unveiled in December last year, the report said. They order government agencies above the township level to include criteria requiring “safe and reliable” processors and operating systems when making purchases, the newspaper said. The US has been aiming to boost domestic semiconductor
Nvidia Corp earned its US$2.2 trillion market cap by producing artificial intelligence (AI) chips that have become the lifeblood powering the new era of generative AI developers from start-ups to Microsoft Corp, OpenAI and Google parent Alphabet Inc. Almost as important to its hardware is the company’s nearly 20 years’ worth of computer code, which helps make competition with the company nearly impossible. More than 4 million global developers rely on Nvidia’s CUDA software platform to build AI and other apps. Now a coalition of tech companies that includes Qualcomm Inc, Google and Intel Corp plans to loosen Nvidia’s chokehold by going
ENERGY IMPACT: The electricity rate hike is expected to add about NT$4 billion to TSMC’s electricity bill a year and cut its annual earnings per share by about NT$0.154 Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has left its long-term gross margin target unchanged despite the government deciding on Friday to raise electricity rates. One of the heaviest power consuming manufacturers in Taiwan, TSMC said it always respects the government’s energy policy and would continue to operate its fabs by making efforts in energy conservation. The chipmaker said it has left a long-term goal of more than 53 percent in gross margin unchanged. The Ministry of Economic Affairs concluded a power rate evaluation meeting on Friday, announcing electricity tariffs would go up by 11 percent on average to about NT$3.4518 per kilowatt-hour (kWh)
OPENING ADDRESS: The CEO is to give a speech on the future of high-performance computing and artificial intelligence at the trade show’s opening on June 3, TAITRA said Advanced Micro Devices Inc (AMD) chairperson and chief executive officer Lisa Su (蘇姿丰) is to deliver the opening keynote speech at Computex Taipei this year, the event’s organizer said in a statement yesterday. Su is to give a speech on the future of high-performance computing (HPC) in the artificial intelligence (AI) era to open Computex, one of the world’s largest computer and technology trade events, at 9:30am on June 3, the Taiwan External Trade Development Council (TAITRA) said. Su is to explore how AMD and the company’s strategic technology partners are pushing the limits of AI and HPC, from data centers to
