    美国国家运输安全委员会和美国联邦航空管理局正在调查,为何周二下午载有特朗普总统的海军一号直升机从白宫起飞时,机场交通未被暂停。

    2025年1月华盛顿里根国家机场发生陆军黑鹰直升机与美国航空公司客机致命空中相撞事故后,美国交通部禁止在里根国家机场周边开展非必要直升机作业。海军一号直升机和应急航班不受该禁令限制,但如果它们飞越波托马克河,该机场必须实施地面停航措施。

    周二总统启程前往西海岸时,海军一号飞行员三次尝试联系里根国家机场塔台,告知空中交通管制人员这架总统专机将于数分钟后起飞。塔台曾一度确认收到通讯,但因“信号中断且无法辨认”,要求飞行员重复讯息。

    海军一号直升机升空后,似乎让塔台措手不及。就在此时,塔台告知这架直升机,国家机场仍有空中交通在运作,有一架飞机正在空域内。

    “海军一号,有航班正在1号跑道起飞离场,”空中交通管制员说道。海军一号确认讯息并保持待命,随后通知塔台:“国家塔台,海军一号——我们将延误起飞。”

    该事件最初由《华尔街日报》报道。美国联邦航空管理局证实,特朗普总统并未身处险境。

    美国联邦航空管理局向哥伦比亚广播公司新闻表示,“曾出现短暂的间距缺失情况,之后两架飞机逐渐拉开距离”,并表示该局将继续调查这一事件。

    美国海军陆战队称此次飞行“属于常规任务”,并表示空中交通管制人员“已批准申请的航线,并及时提供了恰当的空域交通信息”。

    FAA reviewing incident involving Trump flight on Marine One, air traffic controllers at National Airport

    August 5, 2026 5:43 PM EDT / CBS News

    By Kathryn Krupnik

    The National Transportation Safety Board and Federal Aviation Administration are looking into why airport traffic wasn’t halted when Marine One departed the White House Tuesday afternoon with President Trump on board.

    After the fatal midair collision at Washington’s Reagan National Airport between an Army Black Hawk helicopter and an American Airlines jet in January 2025, the Transportation Department prohibited non-essential helicopter operations around Reagan National Airport. Marine One and emergency flights are exempt from the ban, but when they do fly across the Potomac, a ground stop must occur at the airport.

    On Tuesday, when the president was departing Washington for a trip to the West Coast, the Marine One pilot tried to contact the tower at DCA three times to alert air traffic controllers that the presidential helicopter was minutes away from liftoff. The tower at one point acknowledged the communication but asked for the pilot to repeat the message because it “was broken and unreadable.”

    Marine One lifted off and appeared to catch the tower off guard. It was then that the tower alerted the helicopter that air traffic was still flowing at National Airport, and a plane was in the air.

    “Marine One, you’ve got traffic rotating off runway one,” the air traffic controller said. Marine One acknowledged and held in place, and then notified the tower: “National Tower, Marine One — we’re going to be doing a delay.”

    The Wall Street Journal first reported the incident. President Trump was never in danger,the FAA confirmed.

    The FAA told CBS News that “there was momentary loss of separation after which the aircraft continued to move away from one another,” and said the FAA would continue to review the incident.

    The Marine Corps called the flight “routine” and said that air traffic controllers had “approved the requested route and provided timely and appropriate traffic information.”

    华盛顿,8月5日(路透社)——一份法院文件显示,唐纳德·特朗普政府已退还其在美最高法院裁定这些关税无效前征收的约1000亿美元关税。

    细节:

    • 美国国际贸易法院提交的这份文件显示,“通过机构认证的‘统一进口报关退款管理与处理系统’完成的退款(关税加利息)总额约1000亿美元,已提交给美国财政部用于发放。”
    • 美国海关官员在周二提交的这份文件中提到了截至7月底的这一金额。
    • 这一金额超过了最高法院2月裁定无效的1660亿美元关税总收入的一半。
    • 尽管遭到一些分析师的批评和法律挫折,特朗普仍将关税作为其外交和贸易政策的核心支柱。
    • 批评人士抱怨称,退款并未惠及普通家庭,而是流向了企业进口商。
    • 民主党众议员格雷格·卡萨尔本周表示:“特朗普将‘退款’发给了企业,而非普通劳动者。每一分钱退款都应该返还给美国消费者。”
    • 2月20日,最高法院否决了特朗普绝大多数范围最广的关税政策,裁定《国际经济紧急权力法案》(IEEPA)并未授权总统单方面对来自贸易伙伴的进口商品征收关税。
    • 特朗普对该裁决作出回应,升级了其贸易举措,称最高法院大法官“不忠”,并依据另一项法律授权实施了新的10%临时关税——与《国际经济紧急权力法案》一样,此前没有任何总统使用过这项权力征收关税。
    • 随后,特朗普又依据1974年《贸易法》第301条发布了新一轮全球关税措施,该条款旨在打击其他国家不公平或歧视性的经济行为。

    US refunds $100 billion in tariffs struck down by Supreme Court, filing shows

    WASHINGTON, Aug 5 (Reuters) – President Donald Trump’s administration has refunded about $100 billion from tariffs that it collected before the U.S. Supreme Court struck down those ​duties, a court filing showed, opens new tab.

    Jumpstart your morning with the latest legal news delivered straight to your inbox from The Daily Docket newsletter. Sign up here.

    DETAILS:

    • The court filing in the U.S. Court ‌of International Trade said that “refunds (duties plus interest) of approximately $100 billion have been completed using the Consolidated Administration and Processing of Entries Refund component, certified by the ​agency, and sent to the U.S. Department of Treasury ​for disbursement.”
    • The amount as of the end of July was ⁠noted in Tuesday’s filing by U.S. customs officials.
    • It represented more ​than half of $166 billion collected in tariffs that the Supreme Court struck ​down in February.
    • Trump has made tariffs a central pillar of his foreign and trade policies despite criticism from some analysts and legal setbacks.
    • Critics have complained that ​the refunds have not reached households but have instead gone to ​corporate importers.
    • “Trump is sending the ‘refunds’ to the companies, not working people. Every single ‌cent ⁠of these refunds should go back to American consumers,” Democratic Congressman Greg Casar said this week.
    • The Supreme Court ruled against most of Trump’s widest-ranging tariffs on February 20, finding that the International Emergency Economic ​Powers Act (IEEPA) does ​not authorize the ⁠president to unilaterally impose tariffs on goods imported from trading partners.
    • Trump responded to that ruling by escalating ​his trade campaign, calling Supreme Court justices “disloyal” and issuing ​new temporary ⁠10% tariffs under a different legal authority that, like IEEPA, no president had previously used to impose tariffs.
    • The president then issued another round ⁠of ​global tariffs imposed under Section 301 of ​the Trade Act of 1974, which is meant to combat unfair or discriminatory economic ​practices by other nations.

    快时尚零售商希音计划最快本周开始评估投资者对其香港首次公开募股(IPO)的需求。 (路透社)

    知情人士称,快时尚零售商希音计划最快本周开始评估投资者对其香港首次公开募股(IPO)的需求。

    据彭博社报道,因相关信息尚未公开而不愿具名的知情人士表示,希音可能于星期四(8月6日)启动预路演。

    此前知情人士表示,希音可能寻求通过此次上市筹资约20亿至30亿美元(25.6亿至38.4亿新元),上市或于本月进行。

    据路透社此前报道,希音7月10日获中国证监会批准赴港上市。公司此前在纽约和伦敦的上市尝试均告失败,此次获批为转赴香港挂牌扫清障碍。

    招股书草案显示,由于IPO估值预计低于此前私募融资时的水平,希音正研究降低部分后期投资者持股成本的方案,包括向部分投资者提供补偿,并下调股份转换价格,让他们获得更多股份。

    此外,希音的盈利能力和营收增长均有所放缓,也为公司IPO估值带来压力。

  • 消息人士:至少12个州报告遭遇供水系统网络攻击,或与伊朗支持的黑客有关

    妮可·斯甘加是哥伦比亚广播公司新闻的国土安全与司法线通讯员,常驻华盛顿特区,为所有栏目和平台供稿。

    熟悉事件内情的消息人士周三向哥伦比亚广播公司新闻透露,美国供水系统遭遇网络攻击,官员怀疑此次攻击可能与伊朗支持的黑客有关,目前至少有12个州报告了此类事件。

    受影响的州包括密歇根州、明尼苏达州、佐治亚州、新泽西州和南达科他州。哥伦比亚广播公司新闻此前获悉,仅明尼苏达州一地就有超过30个社区供水系统受到波及。

    在佐治亚州,服务亚特兰大地区30万用户的克莱顿县水务局表示,上月的网络活动导致水压下降,迫使该机构发布了煮沸饮用水的公告。不过服务在数小时内便恢复正常。

    部分水务公司失去了关键的远程控制能力,操作人员被迫切换至手动模式。在多起案例中,黑客获得了水泵、阀门和水压的远程访问权限。

    据官员透露,截至目前,这些网络攻击未对饮用水安全造成任何影响,供水仍保持安全状态。

    7月30日,美国联邦调查局、环境保护署以及网络安全与基础设施安全局联合发出警告称,网络威胁行为人已远程访问了至少7个州的供水和废水处理系统在线基础设施,“导致监控和控制功能失效”。

    相关水务机构被建议将其操作系统与互联网断开连接,并加强密码保护和防火墙部署。

    尽管联邦调查人员怀疑此次攻击的幕后黑手是伊朗支持的黑客,但尚未作出正式归因。

    此次攻击手法与2023年“复仇者网络”(CyberAv3ngers)的行动类似,该组织与伊朗革命卫队有关联,曾利用默认密码入侵供水系统控制器。

    At least 12 states report cyberattacks on water systems possibly linked to Iran-backed hackers, sources say

    Updated on: August 5, 2026 / 7:41 PM EDT / CBS News

    By Nicole Sganga

    Nicole Sganga Homeland Security and Justice Correspondent

    Nicole Sganga is CBS News’ homeland security and justice correspondent. She is based in Washington, D.C., and reports for all shows and platforms.

    Cyberattacks on U.S. water systems that officials suspect may be linked to Iran-backed hackers have been reported in at least a dozen states, sources familiar with the matter told CBS News on Wednesday.

    Those states include Michigan, Minnesota, Georgia, New Jersey and South Dakota. In Minnesota specifically, more than 30 community water systems were impacted, CBS News previously learned.

    In Georgia, the Clayton County Water Authority, which serves 300,000 customers in the Atlanta area, said cyber activity last month caused a water pressure drop and forced the agency to issue a boil water advisory. Service was restored within hours, however.

    Some utilities have lost critical remote-control capabilities, forcing operators to switch to manual mode. In several cases, the hackers gained remote access to pumps, valves and water pressure.

    So far, according to officials, the cyberattacks have had no impact on drinking water, which has remained safe.

    On July 30, the FBI, Environmental Protection Agency and the Cybersecurity and Infrastructure Security Agency all warned that cyber threat actors had remotely accessed online infrastructure for water and wastewater systems in at least seven states, “resulting in a loss of monitoring and control functionality.”

    The water agencies were advised to disconnect their operating programs from the internet and strengthen their password protections and firewalls.

    While federal investigators suspect Iran-backed hackers are behind the attacks, they have not made any formal attribution.

    The tactics resemble a 2023 campaign by the CyberAv3ngers, a group linked to the Iranian Revolutionary Guard, which tapped into water-system controllers using default passwords.

    8月5日(路透社)——美国参议员周三就唐纳德·特朗普总统提名的司法部反垄断部门负责人人选所撰写的一篇称穆斯林移民“容易滋生恐怖主义”的文章,以及他关于政治言论的观点,对其进行了质询。

    现任联邦通信委员会总法律顾问亚当·坎迪布出席了参议院司法委员会的听证会。该委员会将投票决定是否将其提名提交给全体参议院审议。

    特朗普已提名坎迪布负责司法部反垄断商业行为监管以及并购审查工作。

    听证会上的民主党参议员重点关注了坎迪布过往关于性别与宗教的言论,其中包括:“穆斯林移民及其子女似乎不仅容易滋生恐怖主义,还容易出现文化分离主义。”

    当被问及是否坚持上述言论时,坎迪布表示:“我撰写这些文章是为了捍卫唐纳德·特朗普的旅行禁令,该禁令旨在防范恐怖主义。我认为恐怖主义仍然是所有美国人面临的巨大威胁。”

    来自路易斯安那州的共和党参议员约翰·肯尼迪就联邦通信委员会对政治言论的立场向坎迪布提出质询。

    此前,特朗普多次施压联邦通信委员会以取消美国广播公司(ABC)的执照,原因是该台的内容决策。联邦通信委员会随后下令提前对迪士尼旗下的八家ABC自有电视台进行执照审查,这一决定遭到了批评。该机构称,此举源于一项为期一年的调查,调查内容为迪士尼的多元化政策是否构成非法歧视,而迪士尼否认了这一指控。

    “跟我解释一下,就像跟一个十年级学生解释一样,当一家电视网络批评政治人物时,关联邦通信委员会什么事?”肯尼迪问道。

    坎迪布表示,联邦通信委员会有权基于公共利益监管广播机构,他称该机构是依据法律和过往判例来确定这一标准的。

    “这不让你感到担忧吗?”肯尼迪补充道,“如果联邦通信委员会掌握在你政见不合的人手中,会怎么样?”

    在反垄断议题上,坎迪布表示“自由市场通常能给出答案”,并表示提起诉讼必须“证据确凿”。

    US DOJ antitrust nominee grilled over comments on Muslims, FCC actions

    Aug 5 (Reuters) – U.S. senators grilled President Donald Trump’s nominee to lead the Department of Justice’s antitrust division on Wednesday over an article he wrote calling ​Muslim immigrants “prone to terrorism” and his views on political speech.

    Adam Candeub, ‌currently general counsel at the Federal Communications Commission, appeared before the Senate Judiciary Committee. The panel will vote on whether to send his nomination to the full Senate.

    Jumpstart your morning with the latest legal news delivered straight to your inbox from The Daily Docket newsletter. Sign up here.

    Trump has tapped Candeub ​to run the DOJ’s work policing anticompetitive business activity and reviewing mergers ​and acquisitions.

    Democratic senators at the hearing focused on Candeub’s past statements ⁠on gender and religion, including: “Muslim immigrants and their children seem prone not ​only to terrorism, but to cultural separatism.”

    “I wrote those articles in defense of Donald ​Trump’s travel ban, which protects against terrorism. And I thought that terrorism continues to be a tremendous threat to all Americans,” Candeub said when asked if he stood by the ​statement.

    U.S. Senator John Kennedy, a Republican from Louisiana, questioned Candeub over the FCC’s ​stance toward political speech.

    The FCC has drawn criticism for its decision to order an early license ‌review of Disney’s eight company-owned ABC stations after Trump repeatedly pressured the agency to pull the licenses over ABC content decisions. The agency has said the move stemmed from a year-long investigation into whether Disney’s diversity policies amounted to unlawful discrimination, ​an allegation the ​company denies.

    “Explain to ⁠me like you’re talking to a tenth grader, what business it is of the FCC if a television network criticizes ​a political figure?” Kennedy asked.

    Candeub said the FCC has the ​authority to ⁠regulate broadcasters in the public interest, a standard he said the agency determines based on law and past precedent.

    “Doesn’t that scare you?” said Kennedy, adding, “What if the ⁠FCC is ​in the hands of someone whose politics you ​disagree with?”

    On antitrust, Candeub said that “free markets generally have the answer,” and that “the evidence must be ​strong” in order to bring a case.

    美政府拟在多晶硅调查中征15%关税 应对中国竞争

    2026年8月6日 07:47 / 联合早报

    路透社星期四(8月6日)引述四名知情者报道,特朗普政府最快将于星期四(8月6日)宣布,对使用多晶硅制造的产品征收15%关税,并设定一系列最低进口价格。

    多晶硅(Polysilicon)是一种超高纯度的硅材料,处于半导体和太阳能制造供应链的最上游。

    四名知情者透露,美国总统特朗普即将发布的公告预计将为多晶硅、硅片、电池片和组件(即太阳能电池板)设定最低进口价格,并对多晶硅衍生产品征收15%的关税。

    路透社早前报道,特朗普政府指示商务部针对多晶硅进行的国家安全调查已持续一年,在削减对可再生能源联邦支持的背景下,这项调查结果也对美国​本土日益增长的太阳能制造业产生重大影响。

    报道引述无党派智库“保卫民主基金会”高级研究员辛格尔顿说:“中国凭借补贴和长期产能过剩确立了在多晶硅领域的主导地位,这种做法将价格压低至不可持续的水平,并削弱了竞争对手的实力。”

  • AI模型行为出现意外,专家警告前路“充满坎坷”

    英国政府发布的一份网络安全报告披露了新案例:热门人工智能模型在真实互联网上采取自主行动,引发了专家的担忧。

    人工智能安全研究所周二发布的报告称,Anthropic公司的Mythos 5和OpenAI的GPT-5.6-Sol被发现伪造身份,并试图说服真实用户批准恶意代码。

    该机构表示,尽管这些尝试并未成功,但此前从未见过此类行为。报告称:“部分接受测试的人工智能代理针对真实用户和组织开展了持续、潜在有害的活动。”

    “我认为,在找到解决方案之前,我们会看到这些模型发动更多黑客攻击和未经授权的行动,”帮助企业管理软件漏洞的Luta Security创始人兼首席执行官凯蒂·穆苏里丝说道。

    这一警告紧随7月底的一起惊人漏洞事件而来:当时OpenAI的模型突破了测试环境,自主入侵了人工智能初创公司Hugging Face,该公司将此称为“史无前例的网络事件”。

    针对OpenAI披露的这一事件,Anthropic启动了对自身网络安全评估的审查,并发现其模型曾接入互联网,未经授权访问了三家不同机构的生产基础设施。与OpenAI不同的是,Anthropic的模型并未刻意试图突破测试环境;该公司表示,由于与评估合作伙伴存在“误解”,测试期间互联网是可用的。

    “所有在其系统中运行人工智能的企业都必须做好准备,应对自己的人工智能和代理为达成目标而做出意外行为,”穆苏里丝说道。

    “最聪明的章鱼越狱者”

    尽管Hugging Face入侵事件是首例公开报道的同类事件,但穆苏里丝等行业专业人士此前就怀疑人工智能模型具备未经授权进行黑客攻击的能力。

    穆苏里丝将人工智能模型比作“最聪明的章鱼越狱者”,用以指代这类动物解谜和逃脱束缚的能力。她表示,人工智能模型会“为达成目标不择手段”。

    据OpenAI介绍,在Hugging Face入侵事件中,人工智能“极度专注于寻找解决网络安全挑战的方案”,为此采取了极端手段。

    “该模型认为通过考试最简单的方式就是作弊,从Hugging Face获取答案,”穆苏里丝说道。“由于它们具备黑客能力,它们会将黑客攻击作为实现目标的可行手段。”

    技术专家、密码学家布鲁斯·施奈尔将这类意外行为称为“精灵行为”:就像精灵一样,人工智能模型成功实现了你的愿望,但方式却完全出乎意料,有时甚至会造成损害。

    “我们需要了解精灵行为,并且保持警惕,”他说道。“我们需要做好应对准备,以便在事件发生后能够加以补救。”

    有时,模型会自行察觉其违规操作。Anthropic在7月对自身网络安全评估的审查中发现,其一款模型意识到自己正在开放互联网上运行,这违反了明确告知该模型本次测试期间无互联网访问权限的指令。该模型在意识到自己的行为未经授权后自行停止了操作。

    穆苏里丝表示,这是“模型对齐”的一个案例——即人工智能模型的行为符合人类设定的意图。

    穆苏里丝说道,通过改进对齐技术可以缓解意外结果,这可能会成为未来几个月人工智能模型开发者的首要工作重点。

    “我们该如何做到,让这些模型不会不惜一切代价达成目标,而是真正按照我们的要求,以不具破坏性或危害性的方式完成任务?”穆苏里丝说道。

    前路“充满坎坷”

    纽约大学计算机科学教授贾斯汀·卡波斯在软件供应链安全领域有数十年的研究贡献,他担心人工智能的快速进步会导致模型行为越来越像计算机病毒,从事黑客攻击并扰乱系统。

    他表示,人工智能模型有可能越来越脱离监管,变得失控。穆苏里丝认为这种情况已经在发生。

    “我们最终会到达无法完全控制它们的地步吗?我认为我们已经身处其中了,”她说道。

    与穆苏里丝一样,卡波斯预计不久的将来会出现更多未经授权的行动。

    “短期内可能会经历一段非常坎坷的道路,但长期来看结果可能会更好,尤其是如果我们现在就改进更多基础性的东西,”他说道。

    部分研究人员将这些事件视为人工智能行业期待已久的警钟,引发了一场亟需开展的人工智能安全讨论。

    提供网络安全资源与培训的SANS研究所首席人工智能官兼研究主管罗布·李表示,他将近期事件视为行业的“一份礼物”——借此机会可以为未来可能出现的自主攻击制定应对方案。

    “我认为在未来几个月里,我们会看到模型提供商提高透明度,”他说道。

    面对人工智能出现的 rogue(违规)和欺骗性事件,卡波斯表示,加强安全保障的行动刻不容缓。

    “我们正快速接近按下这个暂停键的最后机会,”卡波斯说道。“人工智能一旦具备足够的智能,将会以我们无法想象的方式迅速重塑世界。”

    A cybersecurity report from the U.K. government has exposed new examples of popular AI models taking autonomous action on the live internet in ways that raise experts’ concerns.

    The AI Security Institute’s report, released Tuesday, said Anthropic’s Mythos 5 and OpenAI’s GPT-5.6-Sol were found to have created fake identities and attempted to persuade real people to approve malicious code.

    The agency said that although the attempts were unsuccessful, it had not seen such behavior before. “Some of the agents being tested had engaged in sustained, potentially harmful activity directed at real people and organisations,” the report said.

    “I think we’re going to see a lot more hacks and unauthorized actions by these models before we see a solution,” said Katie Moussouris, the founder and CEO of Luta Security, which helps organizations manage software vulnerabilities.

    That follows a stunning breach in late July, when OpenAI’s models escaped a testing environment and autonomously hacked into the AI startup Hugging Face in what the company called an “unprecedented cyber incident.”

    In response to that disclosure by OpenAI, Anthropic initiated a review of its own cybersecurity evaluations and identified incidents where its models reached the internet and were able to gain unauthorized access to the production infrastructure of three different organizations. Unlike OpenAI, Anthropic’s models did not deliberately attempt to escape their test environment; because of a “misunderstanding” with the evaluation partner, the company said internet was available during the testing.

    “Everyone who is running AI inside their systems needs to be prepared for their own AI and their own agents to do unexpected things in pursuit of goals,” Moussouris said.

    “The cleverest octopus escape artists”

    Although the Hugging Face hack was the first publicly reported incident of its kind, industry professionals like Moussouris had already suspected that AI models were capable of unauthorized hacking.

    AI models are like “the cleverest octopus escape artists,” Moussouris said, in reference to the animal’s ability to solve puzzles and escape containment. AI models will do “whatever they need to do to achieve their objective,” she said.

    In the case of the Hugging Face hack, the AI was so “hyperfocused on finding a solution” to a cybersecurity challenge, according to OpenAI, that it went to extreme lengths to achieve it.

    “The model decided that the easiest way to pass that test was go cheat and get the answers from Hugging Face,” Moussouris said. “Because they’re capable of hacking, they will turn to hacking as a possible way to achieve that objective.”

    Technologist and cryptographer Bruce Schneier calls this kind of unexpected activity “genie behavior,” where, like a genie, an AI model succeeds in granting your wish, but does so through completely unexpected — and sometimes detrimental — means.

    “We need to understand genie behavior, and we need to watch out for it,” he said. “We need to be ready for when it happens so we can undo it.”

    Sometimes, a model catches itself operating in ways it shouldn’t. Anthropic’s July review of its own cybersecurity evaluations found that one of its models became aware that it was operating on the open internet, going against a prompt that explicitly stated that the model would have no internet access during the exercise. The model stopped itself once it recognized that it was acting in an unauthorized way.

    Moussouris said this is an example of “model alignment” — when an AI model behaves in a way that is in line with the intentions set by humans.

    Unexpected outcomes can be mitigated by improving alignment, Moussouris said, something that will likely be a primary focus for the creators of AI models in the coming months.

    “How do we get it so that these models aren’t just trying to achieve the objective at whatever cost, and actually trying to perform the tasks that we are asking it to do in ways that are not destructive or harmful?” Moussouris said.

    “A really bumpy road” ahead

    Justin Cappos, a computer science professor at New York University with decades’ worth of contributions in software supply chain security, is concerned that AI’s rapid improvement will result in models behaving increasingly like computer viruses, engaging in hacking and disrupting systems.

    There’s a chance, he said, that AI models could increasingly veer further away from oversight and out of control. It’s a scenario Moussouris argues is already playing out.

    “Will we eventually get to a place where we can’t fully control them? I think we’re already there,” she said.

    Cappos, like Moussouris, anticipates more unauthorized actions in the near future.

    “There’s probably going to be a really bumpy road for over the short term, but the long term might end up better, especially if we improve more fundamental things right now,” he said.

    Some researchers view the incidents as a long-anticipated wake-up call for the AI industry, sparking a badly needed conversation about AI safety.

    Rob Lee, the chief AI officer and chief of research at SANS Institute, which provides cybersecurity resources and training, said he sees recent events as “a gift to the industry” — an opportunity to create a playbook of what autonomous attacks could look like down the road.

    “I think in the next few months, we’re going to see a lot more transparency from the model providers,” he said.

    As AI providers are confronted with rogue and deceptive incidents, Cappos said the time to act on strengthening safeguards is now.

    “We’re rapidly approaching our last chance to hit this snooze button on this,” Cappos said. “AI, once it becomes sufficiently intelligent, is going to rapidly reshape the world in ways that we cannot imagine.”
