Health care professionals are increasingly using artificial intelligence to better diagnose and treat serious medical conditions. However, with the use of artificial intelligence in medicine growing, there are concerns among medical ethicists about how emerging technologies should be deployed

Kenyan companies, facing economic challenges, are turning to artificial intelligence to reduce production and advertising expenses. That’s causing anxiety among artists and ad agencies, who fear reduced income and job losses if AI can replace the work they’ve always done. Mohammed Yusuf reports from Nairobi.

LONDON — Lockbit, a notorious cybercrime gang that holds its victims' data for ransom, has been disrupted in a rare international law enforcement operation by Britain’s National Crime Agency, the U.S. Federal Bureau of Investigation, Europol and a coalition of international police agencies, according to a post on the gang’s extortion website on Monday. “This site is now under the control of the National Crime Agency of the UK, working in close cooperation with the FBI and the international law enforcement task force, ‘Operation Cronos,’” the post said. An NCA spokesperson confirmed that the agency had disrupted the gang and said the operation was "ongoing and developing." A representative for Lockbit did not respond to messages from Reuters seeking comment but did post messages on an encrypted messaging app saying it had backup servers not affected by the law enforcement action. The U.S. Department of Justice and the FBI did not immediately respond to requests for comment. The post named other international police organizations from France, Japan, Switzerland, Canada, Australia, Sweden, the Netherlands, Finland and Germany. Lockbit and its affiliates have hacked some of the world’s largest organizations in recent months. The gang makes money by stealing sensitive data and threatening to leak it if victims fail to pay an extortionate ransom. Its affiliates are like-minded criminal groups that are recruited by the group to wage attacks using Lockbit’s digital extortion tools. Ransomware is malicious software that encrypts data. Lockbit makes money by coercing its targets into paying ransom to decrypt or unlock that data with a digital key. Lockbit was discovered in 2020 when its eponymous malicious software was found on Russian-language cybercrime forums, leading some security analysts to believe the gang is based in Russia. The gang has not professed support for any government, however, and no government has formally attributed it to a nation-state. On its now-defunct dark web site, the group said it was “located in the Netherlands, completely apolitical and only interested in money.” “They are the Walmart of ransomware groups, they run it like a business — that’s what makes them different,” said Jon DiMaggio, chief security strategist at Analyst1, a U.S.-based cybersecurity firm. “They are arguably the biggest ransomware crew today.” Officials in the United States, where Lockbit has hit more than 1,700 organizations in nearly every industry from financial services and food to schools, transportation and government departments, have described the group as the world’s top ransomware threat. In November of last year, Lockbit published internal data from Boeing, one of the world's largest defense and space contractors. In early 2023, Britain’s Royal Mail faced severe disruption after an attack by the group. According to vx-underground, a cybersecurity research website, Lockbit said in a statement in Russian and shared on Tox, an encrypted messaging app, that the FBI hit its servers that run on the programming language PHP. The statement, which Reuters could not verify independently, added that it has backup servers without PHP that "are not touched." On X, formerly known as Twitter, vx-underground shared screenshots showing the control panel used by Lockbit's affiliates to launch attacks had been replaced with a message from law enforcement: "We have source code, details of the victims you have attacked, the amount of money extorted, the data stolen, chats, and much, much more," it said. "We may be in touch with you very soon" it added. "Have a nice day." Before it was taken down, Lockbit's website displayed an ever-growing gallery of victim organizations that was updated nearly daily. Next to their names were digital clocks that showed the number of days left to the deadline given to each organization to provide ransom payment. On Monday, Lockbit’s site displayed a similar countdown, but from the law enforcement agencies who hacked the hackers: "Return here for more information at: 11:30 GMT on Tuesday 20th Feb." the post said. Don Smith, vice president of Secureworks, an arm of Dell Technologies, said Lockbit was the most prolific and dominant ransomware operator in a highly competitive underground market. “To put today’s takedown into context, based on leak site data, Lockbit had a 25% share of the ransomware market. Their nearest rival was Blackcat at around 8.5%, and after that it really starts to fragment," Smith said. "Lockbit dwarfed all other groups and today’s action is highly significant."

WASHINGTON — U.S. lawmakers are raising alarms about what they see as America's failure to compete with China in biotechnology, warning of the risks to U.S. national security and commercial interests. But as the two countries' rivalry expands into the biotech industry, some say that shutting out Chinese companies would only hurt the U.S. Biotechnology promises to revolutionize everyday life, with scientists and researchers using it to make rapid advances in medical treatment, genetic engineering in agriculture and novel biomaterials. Because of its potential, it has caught the attention of both the Chinese and U.S. governments. Bills have been introduced in the House and Senate to bar "foreign adversary biotech companies of concern" from doing business with federally funded medical providers. The bills name four Chinese-owned companies. The Chinese Embassy said those behind the bills have an "ideological bias" and seek to suppress Chinese companies "under false pretexts." It demanded that Chinese companies be given "open, just, and non-discriminatory treatment." The debate over biotechnology is taking place as the Biden administration tries to stabilize the volatile U.S.-China relationship, which has been battered by a range of issues, including a trade war, the COVID-19 pandemic, cybersecurity and militarization in the South China Sea. Critics of the legislation warn that restrictions on Chinese companies would impede advances that could bring a greater good. "In biotech, one cannot maintain competitiveness by walling off others," said Abigail Coplin, an assistant professor at Vassar College who specializes in China's biotech industry. She said she was worried that U.S. policymakers would get too obsessed with the technology's military applications at the cost of hindering efforts to cure disease and feed the world's population. In a letter to senators sponsoring the bill, Rachel King, chief executive officer of the trade association Biotechnology Innovation Organization, said the legislation would "do untold damage to the drug development supply chain both for treatments currently approved and on market as well as for development pipelines decades in the making." But supporters say the legislation is crucial to protecting U.S. interests. The National Security Commission on Emerging Biotechnology, a group created by the U.S. Senate to review the industry, said the bill would help secure the data of the federal government and of American citizens and it would discourage unfair competition from Chinese companies. The commission warned that advancement in biotechnology can result not only in economic benefits but also rapid changes in military capabilities. Much is at stake, said Rep. Mike Gallagher, chair of the House Select Committee on the Chinese Communist Party. Gallagher introduced the House version of the bill and last week led a congressional delegation to Boston to meet with biotech executives. "It's not just a supply chain battle or a national security battle or an economic security battle; I would submit it's a moral and ethical battle," Gallagher said. "Just as the sector advances at a really astronomic pace, the country who wins the race will set the ethical standards around how these technologies are used." He argues that the U.S. must "set the rules of the road" and if not, "we're going to live in a less free, less moral world as a result." Both the United States and China, the world's two largest economies, have identified biotech as a critical national interest. The Biden administration has put forward a "whole-of-government approach" to advance biotechnology and biomanufacturing that is important for health, climate change, energy, food security, agriculture and supply chain resilience. The Chinese government has plans to develop a "national strategic technology force" in biotech, which would be tasked with making breakthroughs and helping China achieve "technological independence," primarily from the U.S. "Both the Chinese government and the Americans have identified biotech as an area important for investment, a sector that presents an opportunity to grow their economy," said Tom Bollyky, the Bloomberg chair in global health at the Council on Foreign Relations. He said any restrictive U.S. measures should be tailored to address military concerns and concerns about genomic data security. "Naturally there's going to be competition, but what's challenging in biotech is that we are talking about human health," Bollyky said. Ray Yip, who founded the U.S. Centers for Disease Control and Prevention office in China, also worries that the rivalry will slow medical advancements. The benefit of coming up with better diagnostics and therapy is beyond any individual country, Yip said, "and will not overshadow the capacity or prestige of the other country." What concerns Anna Puglisi, a senior fellow at Georgetown University's Center for Security and Emerging Technology, is Beijing's lack of transparency and its unfair market practices. "Competition is one thing. Unfair competition is another thing," she said. Puglisi described BGI, a major Chinese biotech company identified in both the House and Senate bills, as "a national champion" that is subsidized and given favored treatment by the state in a system that "blurs private and public as well as civilian and military." "This system creates market distortions and undermines the global norms of science by using researchers and academic and commercial entities to further the goals of the state," Puglisi said. BGI, which has stressed its private ownership, offers genetic testing kits and a popular prenatal screening test to detect Down syndrome and other conditions. U.S. lawmakers say they are concerned such data could end up in the hands of the Chinese government. The Defense Department has listed BGI as a Chinese military company, and the Commerce Department has blacklisted it on human rights grounds, citing a risk that BGI technology might have contributed to surveillance. BGI has rejected the allegations. In raising its concerns about BGI, the National Security Commission on Emerging Biotechnology says the company is required to share data with the Chinese government, has partnered with the Chinese military, and has received considerable Chinese state funding and support. State subsidies have allowed BGI to offer genomic sequencing services at a highly competitive price that is attractive to U.S. researchers, according to the commission. The genomic data, once in the hands of the Chinese government, "represents a strategic asset that has privacy, security, economic, and ethical implications," it said. BGI could not immediately be reached for comment.

paris — A new artificial intelligence tool that promises to create short videos from simple text commands has raised concerns along with questions from artists and media professionals.  OpenAI, the creator of ChatGPT and image generator DALL-E, said Thursday it was testing a text-to-video model called "Sora" that can allow users to create realistic videos with simple prompts.  The San Francisco-based startup says Sora can "generate complex scenes with multiple characters, specific types of motion, and accurate details of the subject and background," but admits it still has limitations, such as possibly "mixing up left and right."  Here are early reactions from industries that could be affected by the new generative artificial intelligence (AI) tool:    Examples of Sora-created clips on OpenAI's website range widely in style and subject, from seemingly real drone footage above a crowded market to an animated bunny-like creature bouncing through a forest.  Thomas Bellenger, founder and art director of Cutback Productions, has been carefully watching the evolution of generative AI image generation.    "There were those who felt that it was an unstoppable groundswell that was progressing at an astonishing rate, and those who just didn't want to see it," said Bellenger, whose France-based company has created large scale visual effects for such touring musicians as Stromae and Justice.  He said the development of generative AI has "created a lot of debate internally" at the company and "a lot of sometimes visceral reactions."  Bellenger noted that Sora has yet to be released, so its capabilities have yet to be tested by the public.  "What is certain is that no one expected such a technological leap forward in just a few weeks," Bellenger said. "It's unheard of."  He said whatever the future holds, they'll "find ways to create differently."  Mixed reaction among creators Video game creators are equally likely to be impacted by the new invention, with reaction among the sector divided between those open to embracing a new tool and those fearing it might replace them.  French video game giant Ubisoft hailed the OpenAI announcement as a "quantum leap forward" with the potential to let players and development teams express their imaginations.  "We've been exploring this potential for a long time," a Ubisoft spokesperson told AFP.  Alain Puget, chief of Nantes-based studio Alkemi, said he won't replace any artists with AI tools, which "only reproduce things done by humans."  Nevertheless, Puget noted, this "visually impressive" tool could be used by small studios to produce more professionally rendered images.  While video "cut scenes" that play out occasionally to advance game storylines are different from player-controlled action, Puget expects tools like Sora to eventually be able to replace "the way we do things."    'A terrifying leap' Basile Simon, a former journalist and current Stanford University researcher, thinks there has been "a terrifying leap forward in the last year" when it comes to generative AI allowing realistic-looking fabrications to be rapidly produced.  He dreads the idea of how such tools will be abused during elections and fears the public will "no longer know what to believe".  Julien Pain of French TV channel France Info's fact-checking program "Vrai ou Faux" (True or False) says he's also worried about abuse of AI tools.  "Until now, it was easy enough to spot fake images, for example by noticing the repetitive faces in the background," Pain said. "What this new software does seems to be on another level."  While OpenAI and U.S. tech titans may promote safety tools, such as industry-wide watermarks that reveal AI-created imagery, "what about tomorrow's competitors in China and Russia?" he posited.  The Fred & Farid agency, which has collaborated with the Longchamp and Budweiser brands and where a studio dedicated to AI was opened in early January, anticipates that "80 percent of brand content will be generated by artificial intelligence."  "Creative genius" will no longer be limited by production skills thanks to generative AI tools, one enthusiast contended.    Stephanie Laporte, chief executive and founder of the OTTA advertising and influencer agency, believes the technology will "force the industry to evolve."  She also anticipates ad companies with lean budgets will resort to AI tools to save money on workers.  A possible exception, she believes, is the luxury segment, where brands are "very sensitive to authenticity" and "will probably use AI sparingly." 

TOKYO — Japan's flagship H3 rocket reached orbit and released two small observation satellites in a key second test following a failed debut launch last year, buoying hope for the country in the global space race. The H3 rocket blasted off from the Tanegashima Space Center on time Saturday morning, two days after its originally scheduled liftoff was delayed by bad weather. The rocket successfully reached orbit at an altitude of about 670 kilometers (about 420 miles) and released two satellites, said the Japan Aerospace Exploration Agency, or JAXA. “We feel so relieved to be able to announce the good results," JAXA President Hiroshi Yamakawa told a news conference. The H3's main missions are to secure independent access to space and be competitive as international demand for satellite launches grows. “We made a big first step today toward achieving that goal," Yamakawa said. The launch is a boost for Japan’s space program following a recent streak of successes, including a historic precision touchdown on the moon of an unmanned spacecraft last month. The liftoff was closely watched as a test for Japan’s space development after H3, in its debut flight last March, failed to ignite the second-stage engine. JAXA and its main contractor, Mitsubishi Heavy Industries, have been developing H3 as a successor to its current mainstay, H-2A, which is set to retire after two more flights. JAXA H3 project manager Masashi Okada called the result “perfect,” saying H3 cleared all missions set for Saturday's flight. “After a long wait, the newborn H3 finally had its first cry.” At 57 meters (187 feet) long, the H3 is designed to carry larger payloads than H-2A at much lower costs of about 50 billion yen ($330 million).

SINGAPORE — Singapore will play host to Asia's biggest air show next week for the first time since the end of COVID border restrictions, with regional travel rebounding and the military side of the show bristling with defensive systems and nervous arms buyers. An expected full return of civil demand in Asia is being tested by an industry-wide supply crunch and macroeconomic headwinds, however — especially in the world's second-largest aviation market, China — while geopolitical tensions have put weapons in the spotlight. "Supply chain issues are limiting the ability of many airlines to upgrade their fleets and service their aircraft," said Association of Asia Pacific Airlines head Subhas Menon. The biennial show will feature the first trip outside Chinese territory for China's first homegrown passenger jet, COMAC's narrow-body C919. With the dominant two plane manufacturers, Airbus and Boeing, struggling to ramp up production and meet demand for new planes, and Boeing struggling with a string of crises, air show attendees will be watching how the Commercial Aircraft Corporation of China, or COMAC, positions itself as a viable alternative. Many inside the industry caution that only four C919s are in service in China; the plane is only certified by Chinese regulators; and the C919 relies on international supply chains. Nevertheless, China's aviation authority has said it would promote the plane internationally this year and pursue European Union Aviation Safety Agency certification. "We have also seen a growing trend where clients are including the C919 option in their fleet evaluation," said Adam Cowburn of Alton Aviation Consultancy. COMAC will be one of two commercial plane makers flying their planes alongside Airbus. Boeing will not send a commercial aircraft to the show this year. It is the first major international industry event since last month's blowout of a door plug on a 737 MAX 9 pushed Boeing into its second safety crisis in five years and sent images of a fuselage with a gaping hole whizzing across the globe. Analyst Sash Tusa of U.K.-based Agency Partners said that in the past, the industry rarely discussed aviation safety in public, on the assumption that any mention would undermine confidence. "But this omerta no longer seems to apply," he added in a note. Environmental impact Singapore will invite industry delegates to discuss aviation's environmental impact and will reveal a plan for making Singapore's aviation sector sustainable. In November, the global aviation industry agreed to lower fuel carbon emissions 5% by 2030, toward a goal of "net zero" carbon emissions by 2050. "For the industry to meet its Fly Net Zero ambitions by 2050, Asia will be a key driver given that it will continue to remain the largest aviation market," Cowburn said. A massive ramp-up in sustainable aviation fuel, or SAF, production is the current hope for meeting these targets, but it costs three to five times more than traditional jet fuel and there are concerns about how to sustainably meet demand. "That awareness of aviation's climate impact has been rising, and the questions about this industry's license to operate have been increasingly raised — without there being a credible path of tackling that problem," said Sami Jauhiainen of refiner Neste, which started refining SAF in Singapore last year. Defense needs Some new freighters are also in demand, delegates said. Amid spiraling tensions over Taiwan, disputes over South China Sea sovereignty and a spike in North Korean missile tests, regional defense budgets are rising. Systems from small drones to complex sub-hunting aircraft will be on display. The war in Ukraine, which has seen extensive use of high-end air defenses, and repeated attacks on Red Sea shipping, may also spur interest in systems that can intercept missiles and drones, as well as intelligence, surveillance and reconnaissance platforms used to keep tabs on adversaries. No Russian companies are listed among the exhibitors at the air show. Six air forces will stage flying demonstrations, including the United States and India.

Washington — The U.S. Justice Department said on Thursday it disrupted a Russian intelligence hacking network. "For the second time in two months, we've disrupted state-sponsored hackers from launching cyber-attacks behind the cover of compromised U.S. routers," U.S. Deputy Attorney General Lisa Monaco said in a statement. The Justice Department said that a January 2024 court-authorized operation neutralized the network of hundreds of small office/home office (SOHO) routers controlled by Russian intelligence and used "to conceal and otherwise enable a variety of crimes."   "In this case, Russian intelligence services turned to criminal groups to help them target home and office routers, but the Justice Department disabled their scheme," Attorney General Merrick Garland added. Garland said the Justice Department was accelerating efforts to disrupt the Russian government's cyber campaigns against the United States and its partners, including Ukraine.

WASHINGTON — Last year, VPN usage in China nearly doubled, according to data from IT education news outlet Techopedia, this despite the country’s strict regime of internet controls of everything from overseas websites to online games. China’s “Great Firewall” is one of the world’s most comprehensive internet censorship regimes, preventing citizens from accessing websites like Instagram, Wikipedia and YouTube, as well most major news organizations including VOA. VPNs are outlawed in China because they allow users to jump the “Great Firewall” and securely connect to the internet outside the country while blocking their IP address. Rob Binns, a journalist with Techopedia, said China’s increasingly strict censorship policies may explain the rise in VPN usage there. “Looking at VPN usage versus what it’s combating, which is online censorship, we are seeing online censorship in a range of countries, particularly China, becoming more strategic and more surgical,” Binns told VOA in an interview.  In 2021, Chinese regulators limited teenagers’ access to video games to three hours per week — from 8 to 9 p.m. on Fridays, Saturdays and Sundays — before unveiling more severe restrictions last December which set spending limits on video game platforms and banned incentives for daily logins. Binns said these regulations on minors may particularly motivate Chinese usage of VPNs. “With that younger demographic, which is traditionally, extremely, highly tech-literate demographic, they're always going to be looking for ways to kind of circumvent that top-down pressure from governments and find ways to get around that,” Binns said. “And if that means turning to VPNs to circumvent that, then that’s certainly what we're seeing.” Analysts say VPNs empower Chinese internet users to discuss major political issues on the internet without facing governmental blowback. “Circumvention tools like VPNs can enable people in China to access the global internet, including spaces where they can express themselves freely without fear of censorship,” Kian Vesteinsson, a senior research analyst for technology and democracy at the nonprofit Freedom House, which advocates for political freedom, told VOA in an emailed response. “During unprecedented nationwide protests in late 2022, many Chinese people used VPNs to sidestep the Great Firewall and share their views on otherwise-inaccessible social media platforms.” Vesteinsson said access to a free, open internet potentially threatens the ruling Chinese Communist Party — hence the government’s crackdowns on internet usage. “Circumvention technology helped produce one of the most open challenges to CCP rule in decades,” Vesteinsson told VOA. “CCP authorities responded to the 2022 protests in part by scrubbing references to VPNs from the Chinese internet.” “People face severe consequences for using prohibited VPNs, particularly if they belong to a marginalized ethnic or religious minority or try to access content censored by the authorities,” Vesteinsson added. “The government even removes discussion of VPNs from China-based social media platforms, preventing people from learning about circumvention technology.” Analysts expect further crackdowns could lead either to additional upticks in VPN usage or a reluctance to use VPNs, depending on how China chooses to further enhance its censorship regime. “The exact nature of the crackdown, as well as accompanying measures are what decides which effects it is likely to have,” Antonia Hmaidi, a senior analyst at the Berlin-based think tank Mercator Institute for China Studies, told VOA in an email. “China has been so successful in managing its internet partly through making the Great Firewall work not only with fear, but also friction and flooding." Hmaidi adds that instead of cracking down, China could also slow the speed of all connections outside the country, which would make it more inconvenient to use VPNs, and maintain an approved list of fast connections for companies.

washington — President Joe Biden’s reelection campaign Monday defended its new TikTok account as a vital way to boost its appeal with young voters, even as his administration continued to raise security concerns about whether the popular social media app might be sharing user data with China’s communist government. The campaign's inaugural post featured the president being quizzed on Sunday's Super Bowl — and included a reference to the latest political conspiracy theory centering on pop superstar Taylor Swift. “The president’s TikTok debut last night — with more than 5 million views and counting — is proof positive of both our commitment and success in finding new, innovative ways to reach voters in an evolving, fragmented and increasingly personalized media environment,” Biden reelection deputy campaign manager Rob Flaherty said in a statement. At the White House, though, national security communications adviser John Kirby said that “there are still national security concerns about the use of TikTok on government devices, and there’s been no change to our policy not to allow that.” Kirby referred most questions about TikTok to the Biden campaign and ducked a more general query about whether it was wise to use the app at all. He said the potential security issues "have to do with concerns about the preservation of data and potential misuse of that data and privacy information by foreign actors.” Both the FBI and the Federal Communications Commission have warned that TikTok's Chinese owner, ByteDance, could share user data — such as browsing history, location and biometric identifiers — with that country's authoritarian government. Biden in 2022 signed legislation banning the use of TikTok by the federal government’s nearly 4 million employees on devices owned by its agencies, with limited exceptions for law enforcement, national security and security research purposes. Separately, the secretive and powerful Committee on Foreign Investment in the United States has been reviewing the app for years while trying unsuccessfully to force TikTok ownership to divest from its parent company. The White House said Monday the review was continuing. With 150 million U.S. users, TikTok is best known for quick snippets of viral dance routines. But Senator Josh Hawley, a Missouri Republican, posted on X that Biden’s campaign is “bragging about using a Chinese spy app even though Biden signed a law banning it on all federal devices.” The Biden campaign said it had been mulling establishing a TikTok account for months and had ultimately done so at the urging of youth activists and organizations, who argued that the app was key to reaching young voters. The campaign said it was using a separate cellphone to engage on TikTok to isolate the app from other work streams and communications, including emails. The campaign said it was taking additional steps but declined to name them, citing security concerns. White House press secretary Karine Jean-Pierre said she wasn't in contact with the campaign and had no advance warning that its TikTok account was going live.
