There are renewed concerns North Korea’s army of hackers is targeting financial institutions to prop up the regime in Pyongyang and possibly fund its weapons programs. A report published Tuesday by the cybersecurity firm Recorded Future finds North Korean aligned actors have been spoofing well-known financial firms in Japan, Vietnam and the United States, sending out emails and documents that, if opened, could grant the hackers access to critical systems. “The targeting of investment banking and venture capital firms may expose sensitive or confidential information of these entities or their customers,” according to the report by Recorded Future’s Insikt Group. “[It] may result in legal or regulatory action, jeopardize pending business negotiations or agreements, or expose information damaging to the company’s strategic investment portfolio,” it said. The report said the most recent cluster of activity took place between September 2022 and March 2023, making use of three new internet addresses and two old addresses, and more than 20 domain names. Some of the domains imitated those used by the targeted financial institutions. Recorded Future’s named the group behind the attacks Threat Activity Group 71 (TAG-71), which is also known as APT38, Bluenoroff, Stardust Chollima and the Lazarus Group. This past April, the U.S. sanctioned three individuals associated with the Lazarus Group, accusing them of helping North Korea launder stolen virtual currencies and turn it into cash. U.S. Treasury officials levied additional sanctions just last month against North Korea’s Technical Reconnaissance Bureau, which develops tools and operations to be carried out …
Japan, Australia, US to Fund Undersea Cable Connection in Micronesia to Counter China’s Influence
Japan announced Tuesday that it joined the United States and Australia in signing a $95 million undersea cable project that will connect East Micronesia island nations to improve networks in the Indo-Pacific region where China is increasingly expanding its influence. The approximately 2,250-kilometer (1,400-mile) undersea cable will connect the state of Kosrae in the Federated State of Micronesia, Tarawa in Kiribati and Nauru to the existing cable landing point located in Pohnpei in Micronesia, according to the Japanese Foreign Ministry. Japan, the United States and Australia have stepped up cooperation with the Pacific Islands, apparently to counter efforts by Beijing to expand its security and economic influence in the region. In a joint statement, the parties said next steps involve a final survey and design and manufacturing of the cable, whose width is about that of a garden hose. The completion is expected around 2025. The announcement comes just over two weeks after leaders of the Quad, a security alliance of Japan, the United States, Australia and India, emphasized the importance of undersea cables as a critical component of communications infrastructure and the foundation for internet connectivity. “Secure and resilient digital connectivity has never been more important,” Matthew Murray, a senior official in the U.S. State Department’s Bureau of East Asian and Pacific Affairs, said in a statement. “The United States is delighted to be part of this project bringing our region closer together.” NEC Corp., which won the contract after a competitive tender, said the cable will ensure high-speed, …

Musk Says China Detailed Plans to Regulate AI
Top Chinese officials told Elon Musk about plans to launch new regulations on artificial intelligence on his recent trip to the Asian giant, the tech billionaire said Monday, in his first comments on the two-day visit. The Twitter owner and Tesla CEO — one of the world’s richest men — held meetings with senior officials in Beijing and employees in Shanghai last week. “Something that is worth noting is that on my recent trip to China, with the senior leadership there, we had, I think, some very productive discussions on artificial intelligence risks, and the need for some oversight or regulation,” Musk said. “And my understanding from those conversations is that China will be initiating AI regulation in China.” Praised China Musk, whose extensive interests in China have long raised eyebrows in Washington, spoke about the exchange in a livestreamed Twitter discussion with Democratic presidential hopeful and vaccine conspiracy theorist Robert Kennedy Jr., the nephew of the late U.S. President John F. Kennedy. Musk did not tweet while in China and Tesla has not released readouts of Musk’s meeting with officials. But official Chinese channels said he lavished praise on the country, including for its “vitality and promise,” and expressed “full confidence in the China market.” Several Chinese companies have been rushing to develop AI services that can mimic human speech since San Francisco-based OpenAI launched ChatGPT in November. But rapid advancements have stoked global alarm over the technology’s potential for disinformation and misuse. Musk didn’t elaborate on his discussions …

Amazon to Pay $31 Million in Privacy Violation Penalties for Alexa Voice Assistant, Ring Camera
Amazon agreed Wednesday to pay a $25 million civil penalty to settle Federal Trade Commission allegations it violated a child privacy law and deceived parents by keeping for years kids’ voice and location data recorded by its popular Alexa voice assistant. Separately, the company agreed to pay $5.8 million in customer refunds for alleged privacy violations involving its doorbell camera Ring. The Alexa-related action orders Amazon to overhaul its data deletion practices and impose stricter, more transparent privacy measures. It also obliges the tech giant to delete certain data collected by its internet-connected digital assistant, which people use for everything from checking the weather to playing games and queueing up music. “Amazon’s history of misleading parents, keeping children’s recordings indefinitely, and flouting parents’ deletion requests violated COPPA (the Child Online Privacy Protection Act) and sacrificed privacy for profits,” Samuel Levine, the FCT consumer protection chief, said in a statement. The 1998 law is designed to shield children from online harms. FTC Commissioner Alvaro Bedoya said in a statement that “when parents asked Amazon to delete their kids’ Alexa voice data, the company did not delete all of it.” The agency ordered the company to delete inactive child accounts as well as certain voice and geolocation data. Amazon kept the kids’ data to refine its voice recognition algorithm, the artificial intelligence behind Alexa, which powers Echo and other smart speakers, Bedoya said. The FTC complaint sends a message to all tech companies who are “sprinting to do the same” amid fierce …
China Eyes Spain in Drive to Conquer European EV Market
The International Energy Agency says Chinese car manufacturers are emerging as a major force in the global electric car market, with more than 50% of all electric cars on roads worldwide now produced in China. Spain is the second-largest vehicle manufacturer in Europe after Germany and its market has become a target for Chinese automakers.

SpaceX’s Starlink Wins Pentagon Contract for Satellite Services for Ukraine
SpaceX’s Starlink, the satellite communications service started by billionaire Elon Musk, now has a Defense Department contract to buy those satellite services for Ukraine, the Pentagon said Thursday. “We continue to work with a range of global partners to ensure Ukraine has the resilient satellite and communication capabilities they need. Satellite communications constitute a vital layer in Ukraine’s overall communications network and the department contracts with Starlink for services of this type,” the Pentagon said in a statement. Starlink has been used by Ukrainian troops for a variety of efforts, including battlefield communications. SpaceX, through private donations and under a separate contract with a U.S. foreign aid agency, has been providing Ukrainians and the country’s military with Starlink internet service, a fast-growing network of more than 4,000 satellites in low Earth orbit, since the beginning of the war in 2022. The Pentagon contract is a boon for SpaceX after Musk, the company’s CEO, said in October it could not afford to indefinitely fund Starlink in Ukraine, an effort he said cost $20 million a month to maintain. Russia has tried to cut off and jam internet services in Ukraine, including attempts to block Starlink in the region, though SpaceX has countered those attacks by hardening the service’s software. The Pentagon did not disclose the terms of the contract, which Bloomberg reported earlier on Thursday, “for operational security reasons and due to the critical nature of these systems.” …
China’s Micron Chips Ban Is Litmus Test for South Korea
The semiconductor trade war between Washington and Beijing may ensnare Seoul as South Korea must decide between backing its closest ally or embracing a lucrative export opportunity presented by China, its top trading partner. The decision will reveal how closely South Korea is aligned with the U.S., its second-largest export market, experts said. The dilemma facing Seoul emerged after China announced that it was banning the use of U.S.-based Micron Technology’s broad range of computer memory and storage technologies. Liu Pengyu, a Chinese Embassy spokesperson in Washington, told VOA’s Korean Service on May 24 that Beijing’s cybersecurity regulators had assessed that Micron’s chips “pose a major security risk to China’s key information infrastructure supply chain and impact China’s national security.” The ban echoed that set by the U.S. on China’s Huawei Technologies in May 2019, when the Trump administration cited security concerns related to the company’s wireless networking equipment, especially those related to 5G. The Biden administration in November 2022 banned approvals of new telecommunications equipment from Huawei and ZTE because the products pose “an unacceptable risk” to U.S. national security. U.S. Representative Mike Gallagher, the Republican chairman of the House Select Committee on Strategic Competition between the United States and the Chinese Communist Party, has called for South Korea to “act to prevent backfilling” the market gap left by Micron.

Key US Official Calls for Tech Companies to ‘Do Something’ About AI
The director of the leading U.S. cybersecurity agency has a message for scientists and top technology company officials who are warning that artificial intelligence could lead to the end of humankind: Take action. “If you actually think that these capabilities can lead to extinction of humanity, well, let’s come together and do something about it,” the Cybersecurity and Infrastructure Security Agency’s Jen Easterly told an audience Wednesday. “While we’re trying to put a regulatory framework in place, think about self-regulation,” she told an Axios News Shapers event in Washington. “Think about what you can do to slow this down.” The comments by the CISA director come just a day after more than 350 researchers and technology executives issued a one-sentence warning about the dangers of artificial intelligence, or AI. “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war,” they said in a post on the website for the Center for AI Safety. Those signing onto the warning included the co-founder and CEO of OpenAI, the company behind Chat GPT, Microsoft’s chief technology officer, the CEO of Google’s AI research lab and Geoffrey Hinton, sometimes called “the godfather of artificial intelligence.” Hinton, notably, quit his job at Google earlier in May to focus on warning others of the dangers of AI. [[ ]] U.S. government officials, like CISA’s Easterly, have likewise been warning about the dangers posed by AI. “AI will be the most powerful capability of …
Theranos Founder Elizabeth Holmes Starts 11-year Sentence for Blood-Testing Hoax
Disgraced Theranos CEO Elizabeth Holmes is in custody at a Texas prison where she could spend the next 11 years for overseeing a blood-testing hoax that became a parable about greed and hubris in Silicon Valley, according to the Federal Bureau of Prisons. Holmes, 39, on Tuesday entered a federal women’s prison camp located in Bryan, Texas — where the federal judge who sentenced Holmes in November recommended she be incarcerated. The minimum-security facility is about 152 kilometers (about 94 miles) northwest of Houston, where Holmes grew up aspiring to become a technology visionary along the lines of Apple co-founder Steve Jobs. As she begins her sentence, Holmes is leaving behind two young children — a son born in July 2021 a few weeks before the start of her trial and a 3-month old daughter who was conceived after a jury convicted her on four felony counts of fraud and conspiracy in January 2022. Holmes has been free on bail since then, most recently living in the San Diego, California, area with the children’s father, William “Billy” Evans. The couple met in 2017 around the same time Holmes was under investigation for the collapse of Theranos, a startup she founded after dropping out of Stanford University when she was just 19. Build up to startup While she was building up Theranos, Holmes grew closer to Ramesh, “Sunny” Balwani, who would become her romantic partner as well as an investor and fellow executive in the Palo Alto, California, company. Together, Holmes …
US Commerce Secretary: US ‘Won’t Tolerate’ China’s Ban on Micron Chips
The United States “won’t tolerate” China’s effective ban on purchases of Micron Technology MU.O memory chips and is working closely with allies to address such “economic coercion,” U.S. Commerce Secretary Gina Raimondo said Saturday. Raimondo told a news conference after a meeting of trade ministers in the U.S.-led Indo-Pacific Economic Framework talks that the U.S. “firmly opposes” China’s actions against Micron. These “target a single U.S. company without any basis in fact, and we see it as plain and simple economic coercion and we won’t tolerate it, nor do we think it will be successful.” China’s cyberspace regulator said May 21 that Micron, the biggest U.S. memory chip maker, had failed its network security review and that it would block operators of key infrastructure from buying from the company, prompting it to predict a revenue reduction. The move came a day after leaders of the G7 industrial democracies agreed to new initiatives to push back against economic coercion by China — a decision noted by Raimondo. “As we said at the G7 and as we have said consistently, we are closely engaging with partners addressing this specific challenge and all challenges related to China’s non-market practices.” Raimondo also raised the Micron issue in a meeting Thursday with China’s Commerce Minister, Wang Wentao. She also said the IPEF agreement on supply chains and other pillars of the talks would be consistent with U.S. investments in the $52 billion CHIPS Act to foster semiconductor production in the United States. “The investments in …
China, South Korea Agree to Strengthen Talks on Chip Industry
China and South Korea have agreed to strengthen dialog and cooperation on semiconductor industry supply chains, amid broader global concerns over chip supplies, sanctions and national security, China’s commerce minister said. Wang Wentao met with South Korean Trade Minister Ahn Duk-geun on the sidelines of the Asia-Pacific Economic Cooperation (APEC) conference in Detroit, which ended Friday. They exchanged views on maintaining the stability of the industrial supply chain and strengthening cooperation in bilateral, regional and multilateral fields, according to a statement from the Chinese Ministry of Commerce on Saturday. Wang also said that China is willing to work with South Korea to deepen trade ties and investment cooperation. However, a South Korean statement on the same meeting did not mention chips, instead saying the country’s trade minister had asked China to stabilize the supply of key raw materials — and asked for a predictable business environment for South Korean companies in China. “The South Korean side expressed that communication is needed between working-level officials over all industries,” not just for semiconductors, a source with knowledge of the matter told Reuters. The source declined to be identified because they were not authorized to speak to the media. South Korea is in the crosshairs of a tit-for-tat row between the United States and China over semiconductors. China’s cyberspace regulator said last week that Micron had failed its network security review and that it would block operators of key infrastructure from buying from the company. The U.S. has pushed for countries to limit …
Regulators Take Aim at AI to Protect Consumers, Workers
As concerns grow over increasingly powerful artificial intelligence systems like ChatGPT, the nation’s financial watchdog says it’s working to ensure that companies follow the law when they’re using AI. Already, automated systems and algorithms help determine credit ratings, loan terms, bank account fees, and other aspects of our financial lives. AI also affects hiring, housing and working conditions. Ben Winters, senior counsel for the Electronic Privacy Information Center, said a joint statement on enforcement released by federal agencies last month was a positive first step. “There’s this narrative that AI is entirely unregulated, which is not really true,” he said. “They’re saying, ‘Just because you use AI to make a decision, that doesn’t mean you’re exempt from responsibility regarding the impacts of that decision. This is our opinion on this. We’re watching.’” In the past year, the Consumer Finance Protection Bureau said it has fined banks over mismanaged automated systems that resulted in wrongful home foreclosures, car repossessions and lost benefit payments, after the institutions relied on new technology and faulty algorithms. There will be no “AI exemptions” to consumer protection, regulators say, pointing to these enforcement actions as examples. Consumer Finance Protection Bureau Director Rohit Chopra said the agency has “already started some work to continue to muscle up internally when it comes to bringing on board data scientists, technologists and others to make sure we can confront these challenges” and that the agency is continuing to identify potentially illegal activity. Representatives from the Federal Trade Commission, the Equal …
U.S., Microsoft Warn Chinese Hackers Attacking ‘Critical’ Infrastructure
State-sponsored Chinese hackers have infiltrated critical U.S. infrastructure networks, the United States, its Western allies and Microsoft said Wednesday while warning that similar espionage attacks could be occurring globally. Microsoft highlighted Guam, a U.S. territory in the Pacific Ocean with a vital military outpost, as one of the targets, but said “malicious” activity had also been detected elsewhere in the United States. The stealthy attack — carried out by a China-sponsored actor dubbed “Volt Typhoon” since mid-2021 — enabled long-term espionage and was likely aimed at hampering the United States if there was conflict in the region, it said. “Microsoft assesses with moderate confidence that this Volt Typhoon campaign is pursuing development of capabilities that could disrupt critical communications infrastructure between the United States and Asia region during future crises,” the statement said. “In this campaign, the affected organizations span the communications, manufacturing, utility, transportation, construction, maritime, government, information technology, and education sectors.” Microsoft’s statement coincided with an advisory released by U.S., Australian, Canadian, New Zealand and British authorities warning that the hacking was likely occurring globally. “This activity affects networks across US critical infrastructure sectors, and the authoring agencies believe the actor could apply the same techniques against these and other sectors worldwide,” they said. ‘Living off the land’ The United States and its allies said the activities involved “living off the land” tactics, which take advantage of built-in network tools to blend in with normal Windows systems. It warned that the hacking could then incorporate legitimate system administration commands that appear …
Analysis: China Steps Up Response to US Chip Moves but Economic Reality Limits How Far
Beijing’s restrictions on American chipmaker Micron in retaliation to sweeping US chip curbs mark a major step up in its response to Washington’s pressure and could open the door for further measures in the geopolitical standoff, analysts say. But they warned President Xi Jinping’s ability to raise the stakes will be limited as he battles to re-energize the world’s number two economy while it struggles to recover from years of zero-Covid-imposed inertia. China on Sunday banned the use of Micron’s chips in critical infrastructure projects, which Beijing said posed “major network security risks” that could affect “national security”. Washington expressed “serious concerns” over the ruling that came just as leaders of the world’s seven richest nations (G7) signed a statement urging Beijing to end “economic coercion”. The move marked a significant shift in China’s response to US measures that have targeted the country’s technology sector, with Gary Ng, a senior economist at Natixis who specializes in the global chip trade, calling it “a landmark case”. He emphasized it was China’s first cybersecurity probe into a foreign company since tighter rules were announced in 2021, and a rare instance when the scope of such reviews was expanded to include national security concerns. “I wouldn’t be surprised if regulators used these reviews as a tool for retaliation in future” when faced with other geopolitical issues, he said. Emily Weinstein, a research fellow at Georgetown University specializing in the US-China tech rivalry, added that the definition of what fell under “critical information infrastructure” …
Microsoft Says China-Backed Hacker Targeted Critical Infrastructure in Guam, US
Microsoft Corp. said on Wednesday it had uncovered malicious activity by a state-sponsored actor based in China aimed at critical infrastructure organizations in Guam and the United States. Microsoft said it assessed with “moderate confidence” that this Volt Typhoon campaign “is pursuing development of capabilities that could disrupt critical communications infrastructure between the United States and Asia region during future crises.” Volt Typhoon has been active since mid-2021 and has targeted critical infrastructure organizations in Guam and elsewhere in the United States, the company said. Guam is home to major U.S. military facilities, including the Andersen Air Force Base, which would be key to responding to any conflict in the Asia-Pacific region. Microsoft said it had notified targeted or compromised customers and provided them with information. The Chinese embassy in Washington did not immediately respond to a Reuters request for comment. …
Apple Inks Multi-Billion-Dollar Deal With Broadcom for U.S.-Made Chips
Apple Inc on Tuesday said it has entered a multi-billion-dollar deal with chipmaker Broadcom Inc. to use chips made in the United States. Under the multi-year deal, Broadcom will develop 5G radio frequency components with Apple that will be designed and built in several U.S. facilities, including Fort Collins, Colorado, where Broadcom has a major factory, Apple said. Broadcom were up 2.2% after the announcement, hitting a record high. The chipmaker is already a major supplier of wireless components to Apple, with about one fifth of its revenue coming from the iPhone maker in its two most recent fiscal year. Apple has been steadily diversifying its supply chains, building more products in India and Vietnam and saying that it will source chips from a new Taiwan Semiconductor Manufacturing Co plant under construction in Arizona. SEE ALSO: A related video by VOA correspondent Michelle Quinn The two companies did not disclose the size of the deal, with Broadcom saying only that the new agreements require it to allocate Apple “sufficient manufacturing capacity and other resources to make these products.” Broadcom and Apple previously had a three-year, $15 billion agreement that Bernstein analyst Stacy Rasgon said was set to expire in June. He said the development was positive for Broadcom, despite the fact that the two firms did not give a time frame for how long the work will last. “It’s good that it removes that overhang,” Rasgon said. “Broadcom has existed over the years with a number of these long-term agreements with …
TikTok Sues to Stop Ban in US State of Montana
TikTok on Monday filed suit in U.S. federal court to stop the northern state of Montana from implementing an overall ban on the video-sharing app. The unprecedented ban, set to start in 2024, violates the constitutionally protected right to free speech, TikTok argued in the suit. “We believe our legal challenge will prevail based on an exceedingly strong set of precedents and facts,” a TikTok spokesperson told AFP. Montana Governor Greg Gianforte signed the prohibition into law on May 17. Gianforte said on Twitter that he endorsed the ban in order to “protect Montanans’ personal and private data from the Chinese Communist Party.” “The state has enacted these extraordinary and unprecedented measures based on nothing more than unfounded speculation,” TikTok contended in its lawsuit. Five TikTok users last week filed a suit of their own, calling on a federal court to overturn Montana’s ban on the app, arguing that it violates their free speech rights. Both suits filed against Montana argue the state is trying to exercise national security power that only the federal government can wield and is violating free speech rights in the process. TikTok called on the federal court to declare the Montana ban on its app unconstitutional and block the state from ever putting it into effect. “Montana can no more ban its residents from viewing or posting to TikTok than it could ban the Wall Street Journal because of who owns it or the ideas it publishes,” the lawsuit filed by TikTok users contends.

Early Warning Systems Send Disaster Deaths Plunging, UN Says
Weather-related disasters have surged over the past 50 years, causing swelling economic damage even as early warning systems have meant dramatically fewer deaths, the United Nations said Monday. Extreme weather, climate and water-related events caused 11,778 reported disasters between 1970 and 2021, new figures from the U.N.’s World Meteorological Organization (WMO) show. Those disasters killed just more than 2 million people and caused $4.3 trillion in economic losses. “The most vulnerable communities unfortunately bear the brunt of weather, climate and water-related hazards,” WMO chief Petteri Taalas said in a statement. The report found that more than 90% of reported deaths worldwide due to disasters in the 51-year period occurred in developing countries. But the agency also said improved early warning systems and coordinated disaster management had significantly reduced the human casualty toll. WMO pointed out in a report issued two years ago covering disaster-linked deaths and losses between 1970 and 2019, that at the beginning of the period the world was seeing more than 50,000 such deaths each year. By the 2010s, the disaster death toll had dropped below 20,000 annually. And in its update of that report, WMO said Monday that 22,608 disaster deaths were recorded globally in 2020 and 2021 combined. ‘Early warnings save lives’ Cyclone Mocha, which wreaked havoc in Myanmar and Bangladesh last week, exemplifies this, Taalas said. Mocha “caused widespread devastation … impacting the poorest of the poor,” he said. But while Myanmar’s junta has put the death toll from the cyclone at 145, Taalas …
SpaceX Launching Saudi Astronauts on Private Flight to Space Station
SpaceX’s next private flight to the International Space Station awaited takeoff Sunday, weather and rocket permitting. The passengers include Saudi Arabia’s first astronauts in decades, as well as a Tennessee businessman who started his own sports car racing team. They’ll be led by a retired NASA astronaut who now works for the company that arranged the 10-day trip. It’s the second charter flight organized by Houston-based Axiom Space. The company would not say how much the latest tickets cost; it previously cited per-seat prices of $55 million. With its Falcon rocket already on the pad, SpaceX targeted a liftoff late Sunday afternoon from NASA’s Kennedy Space Center. It’s the same spot where Saudi Arabia’s first astronaut, a prince, soared in 1985. Representing the Saudi Arabian government this time are Rayyanah Barnawi, a stem cell researcher set to become the kingdom’s first woman in space, and Royal Saudi Air Force fighter pilot Ali al-Qarni. Rounding out the crew: John Shoffner, the racecar buff; and Peggy Whitson, who holds the U.S. record for the most accumulated time in space at 665 days. …

China Tells Tech Manufacturers: Stop Using US-Made Micron Chips
Stepping up a feud with Washington over technology and security, China’s government Sunday told users of computer equipment deemed sensitive to stop buying products from the biggest U.S. memory chipmaker, Micron Technology Inc. Micron products have unspecified “serious network security risks” that pose hazards to China’s information infrastructure and affect national security, the Cyberspace Administration of China said on its website. Its six-sentence statement gave no details. “Operators of critical information infrastructure in China should stop purchasing products from Micron Co.,” the agency said. The United States, Europe and Japan are reducing Chinese access to advanced chipmaking and other technology they say might be used in weapons at a time when President Xi Jinping’s government has threatened to attack Taiwan and is increasingly assertive toward Japan and other neighbors. Chinese officials have warned of unspecified consequences but appear to be struggling to find ways to retaliate without hurting China’s smartphone producers and other industries and efforts to develop its own processor chip suppliers. An official review of Micron under China’s increasingly stringent information security laws was announced April 4, hours after Japan joined Washington in imposing restrictions on Chinese access to technology to make processor chips on security grounds. Foreign companies have been rattled by police raids on two consulting firms, Bain & Co. and Capvision, and a due diligence firm, Mintz Group. Chinese authorities have declined to explain the raids but said foreign companies are obliged to obey the law. Business groups and the U.S. government have appealed to …
