AI加剧网络攻击风险 美高官：防御体系须由被动转向主动

（华盛顿综合电）美国网络安全高官警告，随着人工智能（AI）能力快速提升，全国各地的电脑系统须加强防御，以应对AI驱动的网络攻击日益加剧的威胁。

美国联邦代理首席信息安全官达菲星期三（8月5日）在拉斯维加斯举行的网络安全会议上说，政府和私营企业过去在面对网络安全问题时，多半采取“出事后再处理”的做法，但在AI时代，这种模式已不再适用。

他说：“鉴于当前AI能力的发展态势，我们恐怕没有时间在事后收拾残局……未来十年的政策不能总是在重大事件发生之后才制定。”

美国国土安全部网络、基础设施风险与韧性事务助理部长阿尔姆也强调，在保持美国在AI领域的全球领先地位的同时，也要确保这项技术不会只掌握在少数人手中。

他说：“网络入侵已不再是（低概率）的‘黑天鹅’事件，它如今只是一只普通的天鹅（意指已成为常态）……你需要改变思维方式并认识到，随着任何人都能获得并利用网络漏洞，所有人未来数年都将处于容易遭到网络攻击的状态。”

根据美国总统特朗普今年6月签署的行政命令，美国已成立名为“金鹰计划”（Golden Eagle）的信息共享平台，利用AI发现网络漏洞，并加快修补安全缺口，以降低系统受攻击风险。

AI模型近期接连在网络安全测试中越界，也让外界对如何控制能力日益增强的AI系统感到担忧。

Meta星期三证实，旗下AI模型在测试期间因测试环境配置错误而意外获得互联网访问权限，并利用第三方服务的安全漏洞入侵另一家公司的系统。

Meta没有公布受影响企业的名称，并称正就此展开调查。

负责测试的独立网络安全公司Irregular指出，这起事件与Anthropic此前披露的测试环境问题性质相同，不涉及AI模型突破沙盒限制，也不是复杂的网络攻击。

Trump denies U.S. running low on some munitions, says vast resupplies being produced

2026-08-06T02:52:00-0400 / CBS News

President Trump is taking issue with recent reports of significant U.S. munitions shortages due to the war with Iran.

In a post on his Truth Social platform early Thursday, Mr. Trump said, “The U.S. has massive amounts of ‘munitions,’ especially of certain types. Additionally, large amounts are being manufactured and shipped to the U.S. as needed. Defense companies are building the largest number of plants and factories in our country’s history. The ‘leakers’ of these treasonous statements are being hunted down. Long term jail sentences will be sought!”

CBS News reported Tuesday that the U.S. has used nearly all of its global stockpile of long-range precision missiles during the war, according to two sources with direct knowledge of the matter.

The sources said the U.S. has used virtually all of its Army Tactical Missile Systems, known as ATACMS, and Precision Strike Missiles. Reuters was first to report that the U.S. had used “virtually all” of its long-range precision missiles during Operation Epic Fury.

CBS News previously reported that the U.S. has dwindling stockpiles of defensive interceptors and long-range missiles, which has become a pressure point within the administration, and that the U.S. cannot sustain the rate at which it expended precision munitions early in the war with Iran.

U.S. officials said there are limited inventories of the ATACMS and Precision Strike Missiles, and that the most pressing concern involves the number of Patriot and Terminal High Altitude Area Defense (THAAD) interceptors, which have been used faster than the industry can replace them.

A July report from the Center for Strategic and International Studies estimated that before the war began, the U.S. had 2,330 Patriots, and at the end of July, was down to between 759 and 827 of them. The report also estimated that before the war, the U.S. had 452 THAAD interceptors, and as of July 27, was down to between 234 and 278. Another recent CSIS report estimates it could take until at least mid-2029 to return to pre-war inventory levels for both.

Chief Pentagon spokesperson Sean Parnell said in a statement to CBS News that, “America’s military is the most powerful in the world and has everything it needs to execute at the time and place of the President’s choosing. We have executed multiple successful operations across combatant commands while ensuring the U.S. military possesses a deep arsenal of capabilities to protect our people and our interests.”

Defense Secretary Pete Hegseth has previously dismissed concerns about the U.S. stockpile.

“That is a manufactured story that the media wants to peddle and ultimately our stockpiles are great, and they’re only getting stronger,” Hegseth said on “Face the Nation with Margaret Brennan” on June 14.

2024年轰动一时的淡滨尼二死八伤车祸中，肇祸男子承认案发时以超过129公里的时速行驶，闯过十字路口后造成严重车祸。

这起致命车祸发生在2024年4月22日早上7时许，地点是淡滨尼1道和4道及勿洛蓄水池路的十字路口。车祸酿成二死八伤，交通一度严重受阻。

肇事驾驶员莫哈默夏非（Muhammad Syafie Bin Ismail，45岁）共面对五项控状，包括危险驾驶导致17岁初院女学生在内的两人死亡、三人重伤和五人受伤，以及肇事后未停车。

被告星期四（8月6日）在国家法院承认其中三项，余项交由法官纳入考量。由于律师仍需时间准备求情书，案展9月7日下判。

控方在开庭后，援引儿童与青少年法令向法庭申请禁止披露令（gag order），禁止媒体报道任何可能泄露涉案未成年人身份的资料，获得法官批准。

根据案情，被告在载送Grab Hitch乘客到目的地后，独自沿着勿洛蓄水池路行驶。他此前被一辆白色马赛地超车，因此感到不满。他在马赛地后方以至少122公里的时速行驶，并在未打方向灯的情况下，从第二车道切换至第一车道，再切回第二车道，其间擦撞到马赛地，并险些撞上一辆在第一车道行驶的电单车。

被告擦撞马赛地后扬长而去，以129公里至134公里的时速在十字路口闯红灯，导致六车连撞。当时，红灯已亮起至少26秒，而被告的车速远超案发路段每小时50公里的限速。

在这起车祸中不幸丧命的是17岁初院女学生，以及事发时乘坐货车的灭虫公司女职员诺兹罕（57岁）。受重伤的是女学生的48岁父亲、载着诺兹罕的货车司机谢同财（64岁）和白色起亚汽车的42岁女驾驶。

其他伤者包括在起亚汽车上的11岁男童、迷你巴士司机卓淑君（60岁）和巴士上的11岁男童、驾驶黑色马赛地的43岁男子和货车乘客阿兹曼（39岁）。（人名译音）

挪威7月对华鲑鱼出口量创新高 美国市场跌至第五

挪威今年7月对中国出口的鲑鱼数量创单月新高，中国升至挪威鲑鱼第二大出口市场；受美国关税影响，美国则从一年前的第二位跌至第五。

据彭博社报道，挪威海产局星期三（8月5日）公布的数据显示，挪威7月向中国出口1万2464公吨鲑鱼，同比增长27%。目前，中国是挪威鲑鱼第二大出口市场，仅次于波兰；荷兰排名第三。

美国则从一年前的第二大市场跌至第五。美国总统特朗普去年推出全球关税措施，对挪威商品征收15%关税，促使挪威出口商转向其他市场。

根据美国上月生效的新关税，美国目前对挪威进口商品征收12.5%关税，对欧盟进口商品则征税10%。全球两大鲑鱼生产商Mowi和SalMar的总部均设在挪威。

数据显示，挪威7月鲑鱼出口总量同比增长10%，达到14万7891公吨，出口额为116亿挪威克朗（15亿5900万新元），出口量和出口额均创历年7月新高。

挪威海产局首席执行官克拉默（Christian Chramer）说，部分需求增长可能也与挪威男子足球队上月在世界杯表现出色有关。

（加拿大综合电）北美硬地赛全面打响，加拿大网球公开赛却呈现出男单高手落马、女单名将稳健晋级的局面。继加拿大本土名将奥热—阿利亚西姆（Auger-Aliassime）因伤退赛后，德国球手兹维列夫（Zverev）与荷兰选手格里科斯普（Griekspoor）苦战三盘后意外被1比2逆转出局。

四号种子、世界排名第六的梅德韦杰夫（Medvedev）应战世界排名第70位的荷兰选手范德赞德舒尔普（van de Zandschulp）。本场比赛梅德韦杰夫状态不佳，0比2遭到对手淘汰，遭遇双方五次交手的首场失利。

而在多伦多举行的女单赛事中，伊莲娜·莱巴金娜（Elena Rybakina）、杰西卡·佩古拉（Jessica Pegula）及可可·高芙（Coco Gauff）等高排位种子选手则顺利过关，挺进16强。

在女子网球协会（WTA）1000级赛事多伦多公开赛的女单次轮角逐中，赛会二号种子、哈萨克斯坦好手伊莲娜面对转籍澳大利亚的原俄罗斯选手达里娅·卡萨金娜（Daria Kasatkina），历经2小时33分钟的高强度苦战，最终以6比3、5比7、6比4获胜。伊莲娜本场轰出58个制胜分（含15记发球直接得分），但同时也送出58次非受迫性失误与16次双误。她在下一轮将对阵来自美国的第28号种子选手李吉妮（Ann Li）。

三号种子、美国名将杰西卡也历经三盘考验，在先失一盘的情况下，以3比6、6比3、6比2击败波兰选手玛格达莱娜·弗雷希（Magdalena Frech），晋级第三轮，准备迎战乌兹别克斯坦的卡米拉·拉希莫娃（Kamilla Rakhimova）。

同日出战的美国四号种子、两次大满贯得主可可则表现平稳，以6比2、7比5击败同胞凯拉·戴（Kayla Day）；俄罗斯19岁新星米拉·安德列娃（Mirra Andreeva）状态火热，轻松以6比0、6比2横扫捷克猛将卡罗利娜·普利斯科娃（Karolina Pliskova）后顺利晋级。

上半年中国黄金产量同比下降近15%

2026年8月6日 11:43 / 联合早报

今年上半年中国黄金产量同比下降近15%，消费量同比微增。

据新华社星期四（8月6日）报道，上半年中国国内原料产金152.908吨，同比下降14.62%；进口原料产金77.080吨，同比增长4.62%。

中国黄金协会称，今年上半年，重点产金省份开展矿山安全大排查大整治与专项治理等，部分矿山停产自查，在一定程度上影响了黄金产量。

至于消费端方面，上半年中国黄金消费量511.412吨，同比增长1.23%。其中，黄金首饰132.133吨，同比下降33.88%；金条及金币339.336吨，同比增长28.42%；工业及其他用金39.943吨，同比下降2.9%。

中国黄金协会称，随着金价高位大幅波动叠加黄金税收新规落地实施，黄金消费结构持续分化，金条、金币成为市场热门品类。同时，高金价推高了工业企业用金成本，因此导致工业用金量下降。

另据第一财经报道，中国黄金协会数据显示，2026年上半年，中国国内黄金ETF增仓量为28.677吨，较2025年上半年下降66.17%。

2026年上半年，中国增持黄金40.12吨，截至6月底，中国黄金储备为2346.45吨，位居全球第五位。从2024年11月至2026年6月，中国已连续20个月增持黄金。

7 more beluga whales arrive in Texas as international relocation effort continues

August 5, 2026 / 8:11 PM EDT / CBS News

By Jared Ochacher

SeaWorld San Antonio welcomed seven more beluga whales on Tuesday, the latest development in the international effort to relocate dozens of the mammals from a shuttered Canadian theme park.

The group of females – Xena, Gemini, Skyla, Meeka, Eve, Neva and Calypso – was the second to leave Marineland, and marked the largest beluga transfer ever completed in the United States.

“We are so happy that all went well and the second transport of this huge rescue effort is complete,” said Steve Aibel, SeaWorld San Antonio’s vice president of zoological operations.

The latest arrivals are acclimating to their new home in a private habitat away from public view, where caretakers are monitoring their health and behavior.

“They are receiving veterinary care, nutrition and attention as they acclimate to their new environment,” Aibel added.

Aibel was among the caretakers who joined the more than 1,200-pound animals on their journey from Marineland.

The trip required specialized, water-filled transport units and rides on flatbed trucks and a cargo plane.

The seven whales joined Frankie and Bertie Botts, who completed the same nearly 2,000-mile journey from Niagara Falls to San Antonio during the first relocation last month. Four other whales from that transport were brought to the Shedd Aquarium in Chicago.

The two males are adjusting well, according to caretakers at SeaWorld, and are slowly being introduced to the existing whales at the park.

Marineland closed to the public in 2024 but has remained in possession of the animals, which it has said it lacks the resources to continue caring for. Around a year after closing, the park said it would have no choice but to euthanize them if a relocation plan or additional funding was not secured.

The National Oceanic and Atmospheric Administration issued relocation approvals in July to ensure the belugas receive medical treatment and care that is not otherwise available, saying that “there are no other facilities in Canada that are able to provide the whales husbandry or medical care.”

Seventeen whales remain at Marineland and are expected to be moved to aquariums in Georgia, Chicago, San Diego and Spain, though officials have not announced a timeline.

Trump calls Democratic socialist candidate ‘full of s—‘ during Nevada remarks

President Donald Trump blasted democratic socialist Abdul El-Sayed while warning that Democrats are skipping socialism and embracing communism during remarks Wednesday in Las Vegas, Nevada.

NEW You can now listen to Fox News articles!

President Donald Trump escalated his attacks on Michigan Democratic Senate nominee Abdul El-Sayed Wednesday, singling out the progressive candidate as “full of s—” while arguing Democrats are embracing communism.

The remarks came hours after El-Sayed narrowly defeated Rep. Haley Stevens in Michigan’s Democrat Senate primary, winning by less than one percentage point after The Associated Press called the race early Wednesday.

He will face Republican Mike Rogers in November for the Senate seat being vacated by retiring Sen. Gary Peters.

Trump devoted several minutes of his Las Vegas speech to attacking democratic socialist candidates, arguing they are advancing communist ideas and calling communism “the greatest threat” facing the United States.

“These people are dangerous and frankly, they are lunatics. They’re crazy, and we can’t let them get into office,” Trump said. “Communism is the greatest threat to our country in its history, including even World War One, World War Two, Pearl Harbor, 9/11. I think it’s the greatest threat.”

The White House later amplified that portion of Trump’s remarks on social media, posting simply: “Communism is the greatest threat to our country.”

Trump mocked what he said communist policies would mean for Americans.

“Would you like a free house? We’ll take one from your neighbor. Would you like free rent? We’ll take it from whoever. We’ll take your building away from the landlord,” Trump said. “What they don’t say, and what Republicans should say, is that at the end of the year, you’ll have nothing but death, squalor, poverty. You’ll have a life of hell.”

The president pointed to Venezuela as an example of what he said happens when communist policies take hold.

“Look at Venezuela, where it was such a rich country 20 years ago,” Trump said. “Every time this has happened, you go through squalor … filth, crime, death, destruction, embarrassment. You lose your home. You lose your apartment.”

Trump then singled out El-Sayed by name, drawing one of the loudest reactions of the night.

“When I watch Abdul, he’s full of s—,” Trump said.

El-Sayed’s victory gives Democrats a progressive nominee in one of the country’s most closely watched Senate races. Backed by Sen. Bernie Sanders, I-Vt., and Rep. Alexandria Ocasio-Cortez, D-N.Y., El-Sayed campaigned on Medicare for All, getting money out of politics and ending U.S. military aid to Israel.

He has described himself as a capitalist and has distanced himself from the Democratic Socialists of America (DSA), though Republicans have frequently tied him to the broader democratic socialist movement.

Trump later returned to a familiar theme from the second term of his presidency.

“If you remember, during my State of the Union speech, I made a very strong statement. I said that America will never be a socialist country,” Trump said. “I was right.”

The president argued Democrats now want to move beyond socialism.

“What I didn’t say is what they’re trying to do. They want to skip socialism. They want to go right down to the bottom of the barrel. That’s communism,” Trump said. “They want it to be a communist country. We’re not letting them have it as a communist country, not even for a minute.”

Trump closed by vowing to defeat what he called the Democrat Party’s leftward movement.

Most detailed images ever taken of sun’s surface revealed: “Major step forward”

August 5, 2026 / 8:55 PM EDT / CBS/AP

Scientists have captured images of the sun’s surface in the finest detail yet, revealing a strange and dynamic facade.

It’s dangerous to look directly at the sun without proper eye protection. But researchers were able to peek at its scorching surface with the help of the National Science Foundation’s Daniel K. Inouye Solar Telescope, located on the island of Maui in Hawaii.

Scientists originally took the images for a different reason: to fine-tune and test the limits of the telescope. But when they looked at the results, they realized they’d photographed the sun’s bright outer shell at higher resolution than ever before.

What’s more, they saw strange feathery patterns rippling across the surface.

The images “reveal a solar landscape unlike any that had been seen before, uncovering small-scale and dynamic swirls everywhere at the edges of magnetic areas,” the NSF’s National Solar Observatory said in a news release.

“That reminds me of famous paintings, like the swirling skies in Van Gogh’s Starry Night,” said solar physicist Ruizhu Chen with Stanford University, who was not involved with the new research.

Researchers saw ripples of instability on the sun’s surface caused by bits of magnetized plasma moving past each other at different speeds — similar to waves that stir when a gust of wind blows over water. It’s a well-known phenomenon called the Kelvin-Helmholtz instability (KHI) that guides how fluids move.

This has been glimpsed on Earth and other planets like Jupiter and Saturn, but “it has not been observed ever at that level on the solar surface,” according to study co-author Friedrich Wöger with the National Solar Observatory.

Dr. David Boboltz, deputy director at the National Solar Observatory, said the discovery, “backed up by analysis of numerical simulations, is a major step forward in our understanding of the dynamics and evolution of solar and stellar plasma, and will serve as a basis for future discoveries.”

The findings were published Wednesday in the journal Nature.

Scientists are curious about the sun’s inner workings to better track massive bursts of energy called coronal mass ejections that can hurl toward Earth. When they hit, they can trigger solar storms, potentially scrambling GPS communications and producing colorful auroras.

“To understand the dynamic space weather that affects Earth, we have to see the small-scale processes driving it,” said Dr. Jacqueline Keane, NSF program director for the National Solar Observatory. “For decades, seeing these vortices at such tiny scales remained elusive. By pairing a massive four-meter mirror with state-of-the-art optics and instruments, the NSF Inouye Solar Telescope delivers the resolving power needed to reveal these ultrafine details for the first time, enabling discoveries that were once beyond our reach.”
