Millions of Canadians found out Friday what it is like to live without access to the internet and mobile phone service.

Rogers Communications, the country’s largest mobile and internet provider, experienced a major outage, beginning Friday morning and lasting most of the day.

The outage affected retailers, credit card and debit transactions, court proceedings, government agencies, calls to emergency services and much more.

“Today we have let you down,” Rogers posted on Twitter, without offering an explanation. “We are working to make this right as quickly as we can. We will continue to keep you updated, including when services will be back online.”

Late Friday, the Toronto-based telecommunications firm said it had begun restoring services.

Twitter said Thursday it removes more than 1 million spam and bot accounts every day.

The removals come as Tesla founder Elon Musk, who is in the process of acquiring the company, continues to pressure Twitter to reduce spam accounts.

He has threatened to cancel the $44 billion deal if Twitter cannot prove spam and bot accounts account for less than 5% of Twitter users.

Musk has vowed to “defeat the spam bots or die trying.”

Twitter has maintained that spam and bot accounts make up less than 5% of the user base since at least 2013. Musk has argued that Twitter underestimates the amount of spam accounts.

Twitter says humans conduct manual reviews of thousands of accounts each quarter to determine if they are bots.

Instagram is blocking posts that mention abortion from public view, in some cases requiring its users to confirm their age before letting them view posts that offer up information about the procedure. 

Over the last day, several Instagram accounts run by abortion rights advocacy groups have found their posts or stories hidden with a warning that described the posts as “sensitive content.” Instagram said it was working to fix the problem Tuesday, describing it as a bug. 

In one example, Instagram covered a post on a page with more than 25,000 followers that shared text reading: “Abortion in America How You Can Help.” The post went on to encourage followers to donate money to abortion organizations and to protest the U.S. Supreme Court’s decision to strip constitutional protections for abortion. 

The post was covered with a warning from Instagram, reading “This photo may contain graphic or violent content.” 

Instagram’s latest snafu follows an Associated Press report that Facebook and Instagram were deleting posts that offered to mail abortion pills to women living in states that now ban abortion procedures. The tech platforms said they were deleting the posts because they violated policies against selling or gifting certain products, including pharmaceuticals, drugs and firearms. 

Yet, the AP’s review found that similar posts offering to mail a gun or marijuana were not removed by Facebook. The company did not respond to questions about the discrepancy. 

Berlin photographer Zoe Noble runs the Instagram page whose post referencing abortion was blocked for viewing. The page, which celebrates women who decide not to have children, has been live for over a year. Monday was the first time a post mentioning abortion was restricted by Instagram, although Noble has mentioned it many times before. 

“I was really confused because we’ve never had this happen before, and we’ve talked about abortion before,” Noble said. “I was really shocked that the word abortion seemed to be flagged.” 

The platform offers no way for users to dispute the restriction. 

The AP identified nearly a dozen other posts that mentioned the word “abortion” and were subsequently covered up by Instagram. All of the posts were informational in nature, and none of the posts featured photos of abortions. An Instagram post by an AP reporter that asked people if they were experiencing the problem was also covered by the company on Tuesday and required users to enter their age in order to view it. 

The AP inquired about the problem on Tuesday morning. Hours later, Instagram’s communication department acknowledged the problem on Twitter, describing it as a glitch. A spokesman for Instagram-owner Meta Platforms Inc. said in an email that the company does not place age restrictions around its abortion content. 

“We’re hearing that people around the world are seeing our ‘sensitivity screens,’ on many different types of content when they shouldn’t be. We’re looking into this bug and working on a fix now,” the company tweeted. 

Tech companies like Meta can hide details about how posts or keywords have been promoted or hidden from view, said Brooke Erin Duffy, a professor at Cornell University who studies social media. 

“This can all take place behind the scenes, and it can be attributed to a glitch,” Duffy said. “We don’t know what happened. That’s what’s chilling about this.

Future waves of COVID-19 might be predicted using internet search data, according to a study published in the journal Scientific Reports.

In the study, researchers watched the number of COVID-related Google searches made across the country and used that information, together with conventional COVID-19 metrics such as confirmed cases, to predict hospital admission rates weeks in advance.

Using the search data provided by Google Trends, scientists were able to build a computational model to forecast COVID-19 hospitalizations. Google Trends is an online portal that provides data on Google search volumes in real time.

“If you have a bunch of people searching for ‘COVID testing sites near me’ … you’re going to still feel the effects of that downstream at the hospital level in terms of admissions,” said data scientist Philip Turk of the University of Mississippi Medical Center, who was not involved in the study. “That gives health care administrators and leaders advance warning to prepare for surges — to stock up on personal protective equipment and staffing and to anticipate a surge coming at them.”

For predictions one or two weeks in advance, the new computer model stacks up well against existing ones. It beats the U.S. Centers for Disease Control and Prevention’s “national ensemble” forecast, which combines models made by many research teams — though there are some single models that outperform it.

Different perspective

According to study co-author Shihao Yang, a data scientist at the Georgia Institute of Technology, the new model’s value is its unique perspective — a data source that is independent of conventional metrics. Yang is working to add the new model to the CDC’s COVID-19 forecasting hub.

Watching trends in how often people Google certain terms, like “cough” or “COVID-19 vaccine,” could help fill in the gaps in places with sparse testing or weak health care systems.

Yang also thinks that his model will be especially useful when new variants pop up. It did a good job of predicting spikes in hospitalizations thought to be associated with new variants such as omicron, without the time delays typical of many other models.

“It’s like an earthquake,” Yang said. “Google search will tell me a few hours ahead that a tsunami is hitting. … A few hours is enough for me to get prepared, allocate resources and inform my staff. I think that’s the information that we are providing here. It’s that window from the earthquake to when the tsunami hit the shore where my model really shines.”

The model considers Google search volumes for 256 COVID-19-specific terms, such as “loss of taste,” “COVID-19 vaccine” and “cough,” together with core statistics like case counts and vaccination rates. It also has temporal and spatial components — terms representing the delay between today’s data and the future hospitalizations it predicts, and how closely connected different states are.

Every week, the model retrains itself using the past 56 days’ worth of data. This keeps the model from being weighed down by older data that don’t reflect how the virus acts now.

Turk previously developed a different model to predict COVID-19 hospitalizations on a local level for the Charlotte, North Carolina, metropolitan area. The new model developed by Yang and his colleagues uses a different method and is the first to make state- and national-level predictions using search data.

Turk was surprised by “just how harmonious” the result was with his earlier work.

“I mean, they’re basically looking at two different models, two different paths,” he said. “It’s a great example of science coming together.”

Using Google search data to make public health forecasts has downsides. For one, Google could stop allowing researchers to use the data at any time, something Yang admits is concerning to his colleagues.

‘Noise’ in searches

Additionally, search data are messy, with lots of random behavior that researchers call “noise,” and the quality varies regionally, so the information needs to be smoothed out during analysis using statistical methods.

Local linguistic quirks can introduce problems because people from different regions sometimes use different words to describe the same thing, as can media coverage when it either raises or calms pandemic fears, Yang said. Privacy protections also introduce complications — user data are aggregated and injected with extra noise before publishing, a protection that makes it impossible to fish out individual users’ information from the public dataset.

Running the model with search data alone didn’t work as well as the model with search data and conventional metrics. Taking out search data and using only conventional COVID-19 metrics to make predictions also hurt the new model’s performance. This indicates that, for this model, the magic is in the mix — both conventional COVID-19 metrics and Google Trends data contain information that is useful for predicting hospitalizations.

“The fact that the data is valuable, and [the] data [is] difficult to process are two independent questions. There [is] information in there,” Yang said. “I can talk to my mom about this. It’s very simple, just intuitive. … If we are able to capture that intuition, I think that’s what makes things work.”

NASA, the National Aeronautics and Space Administration, has successfully completed its first rocket launch from a commercial space facility outside of the United States. A 13-meter rocket blasted off Monday from a site in the Australian outback.

A 13-meter sub-orbital rocket took off from the newly built Arnhem Space Centre in Australia’s Northern Territory Monday. Lift-off was delayed by about two hours because of strong winds and heavy rain.

The launch was the first of its kind in Australia in more than 25 years and the first of three scheduled NASA missions from the site.

Researchers hope the information gathered from the flights will help them understand how light from a star could affect the habitability of nearby planets. They have said that this type of study can only be carried out in the Southern Hemisphere.

The unmanned flight briefly scanned the Milky Way, measuring X-Ray emissions and analyzing the structure of stars.

Brad Tucker, an astrophysicist at the Australian National University, told Australian television that the launch is part of a project to boost the domestic space industry.

“When you build a satellite you have to go overseas to do it and so the fact that we are now seeing this build-up of launching from Australia this is, kind of, that final piece of the puzzle to having, you know, a really massive industry in this sector of space and then we see that that, kind of, the first group that says, yes, we want to do it, we want to be a part of the story is Nasa, you know, it just, kind of, gives the street cred[ibility] so to speak that you are on the right track from what you are thinking,” he said.

The Arnhem Space Center is the world’s only commercially owned equatorial launch facility.

The center is built on Aboriginal land. Tribal elders hope the project will provide jobs and opportunities for young First Nations people.

Officials said the center combines one of the “oldest cultures in the world with some of the most advanced technology ever.”

The next NASA rocket will be launched in the Northern Territory on July 4, and the third will take off on July 12.

About 75 NASA staff have travelled to northern Australia for all three launches.

Australia is working to increase its capabilities in space. This year, it announced a new defense agency that would work to counter China and Russia’s ambitions in space. Along with the United States, the two countries are reported to have tested weapons that could destroy a satellite.

The Australian Space Agency was created in July 2018 to “support the growth and transformation” of the nation’s space industry.”

Coinciding with unrelenting cyberattacks against Ukraine, state-backed Russian hackers have engaged in “strategic espionage” against governments, think tanks, businesses and aid groups in 42 countries supporting Kyiv, Microsoft said in a report Wednesday.

“Since the start of the war, the Russian targeting [of Ukraine’s allies] has been successful 29 percent of the time,” Microsoft President Brad Smith wrote, with data stolen in at least one-quarter of the successful network intrusions.

“As a coalition of countries has come together to defend Ukraine, Russian intelligence agencies have stepped up network penetration and espionage activities targeting allied governments outside Ukraine,” Smith said.

Nearly two-thirds of the cyberespionage targets involved NATO members. The United States was the prime target and Poland, the main conduit for military assistance flowing to Ukraine, was No. 2. In the past two months, Denmark, Norway, Finland, Sweden and Turkey have seen stepped-up targeting.

A striking exception is Estonia, where Microsoft said it has detected no Russian cyber intrusions since Russia invaded Ukraine on Feb. 24. The company credited Estonia’s adoption of cloud computing, where it’s easier to detect intruders. “Significant collective defensive weaknesses remain” among some other European governments, Microsoft said, without identifying them.

Half of the 128 organizations targeted are government agencies and 12% are nongovernmental agencies, typically think tanks or humanitarian groups, according to the 28-page report. Other targets include telecommunications, energy and defense companies.

Microsoft said Ukraine’s cyber defenses “have proven stronger” overall than Russia’s capabilities in “waves of destructive cyberattacks against 48 distinct Ukrainian agencies and enterprises.” Moscow’s military hackers have been cautious not to unleash destructive data-destroying worms that could spread outside Ukraine, as the NotPetya virus did in 2017, the report noted.

“During the past month, as the Russian military moved to concentrate its attacks in the Donbas region, the number of destructive attacks has fallen,” according to the report, “Defending Ukraine: Early Lessons from the Cyber War.” The Redmond, Washington, company has unique insight in the domain due to the ubiquity of its software and threat detection teams.

Microsoft said Ukraine has also set an example in data safeguarding. Ukraine went from storing its data locally on servers in government buildings a week before the Russian invasion — making them vulnerable to aerial attack — to dispersing that data in the cloud, hosted in data centers across Europe.

The report also assessed Russian disinformation and propaganda aimed at “undermining Western unity and deflecting criticism of Russian military war crimes” and wooing people in nonaligned countries.

Using artificial intelligence tools, Microsoft said, it estimated “Russian cyber influence operations successfully increased the spread of Russian propaganda after the war began by 216 percent in Ukraine and 82 percent in the United States.”

Twitter’s board has recommended unanimously that shareholders approve the proposed $44 billion sale of the company to billionaire and Tesla CEO Elon Musk, according to a regulatory filing Tuesday.

Musk reiterated his desire to move forward with the acquisition last week during a virtual meeting with Twitter employees, though shares of Twitter remain far below his offering price, signaling considerable doubt that it will happen.

Shares rose about 3% to $38.98 before the opening bell Tuesday, far short of the $54.20 per-share that Musk has offered for each share. The company’s stock last reached that level on April 5 when it offered Musk a seat on the board before he had offered to buy all of Twitter.

In a filing with the U.S. Securities and Exchange Commission detailing on Tuesday detailing a litter to investors, Twitter’s board of directors said that it “unanimously recommends that you vote (for) the adoption of the merger agreement.” If the deal were to close now, investors in the company would pocket a profit of $15.22 for each share they own.

“I’m in a cryptocurrency chat group at work,” software engineer Adam Hickey of San Diego, California told VOA.

Over the last few days, Hickey said, members of the group have been writing things like, “Bloodbath” and, “Are we still good?”

“It shook me, honestly,” he admitted. “I just had to stop looking at my balance. At one point, months ago, my investment in crypto had tripled. Now I’m down 40%.”

Hickey is far from alone. Serious and casual investors across the United States have seen the value of their investments in the publicly available digital asset known as cryptocurrency shrink dramatically in recent months, with steep plunges recorded in just the last week.

The value of bitcoin, the most popular form of cryptocurrency, has dropped more than 70% since its peak in November of last year, erasing more than 18 months of growth and causing many investors to wonder if this is the bottom, or if the worst is still to come.

“I have to remind myself that when I got into bitcoin in 2017, it was more of something I just kind of hoped would be the next Amazon.com,” Hickey said. Like many others, Hickey dreamed cryptocurrency could be a way to get rich in the long-term, or at least would be a part of his retirement savings.

“I’ve always seen it as a long-term investment. Still, this is the most nervous I’ve been about it,” he said. “You hear people on social media saying this is all a Ponzi scheme. Now I’m having thoughts like maybe those warnings are right – that the people pushing bitcoin so hard are the ones who bought it at the earliest low prices. Of course they want people to buy and drive the value back up. It’s good for them, but is it good for me?” 

Getting in 

Those skeptical of cryptocurrency point to its lack of regulatory oversight from government as a major reason for concern, making it susceptible to scams and wild price fluctuations.

“I’ve always seen it as a highly speculative investment,” said Marigny deMauriac, a certified financial planner in New Orleans, Louisiana. “This isn’t something any individual should have the majority of their wealth in unless they’re looking to take a significant amount of unnecessary risk.”

“I tell my clients to stay clear of investing any significant portion of their wealth in cryptocurrency, or any other highly speculative investment type,” deMaruiac told VOA. Many of the most ardent cryptocurrency supporters, however, invest precisely because it isn’t tied to governments as traditional currencies are. Digital currency’s demonstrated capacity for meteoric rises is a big part of its appeal. 

Steve Ryan, a self-employed poker player living in Las Vegas, Nevada, began investing in digital currency nearly a decade ago. “I’ve been in it for so long, I understand this stuff much better than your average person who only read about it on the internet a year or two ago,” he said.

Ryan invested on the advice of entrepreneurial friends; back when a single bitcoin sold for only a couple of hundred dollars as opposed to the tens of thousands they sell for today.

“Most of my money is in crypto, and I wish I had kept more in there rather than selling some of it,” he told VOA. “Even after this downturn, I’d be a multimillionaire had I kept it all in.”

Losing value 

U.S. inflation at 40-year highs has caused the Federal Reserve to raise interest rates, sending jitters throughout financial markets. At the same time, some Americans have lost their appetite for riskier investments.

Many have sold their cryptocurrency holdings and reinvested in safer, more stable assets. At the end of last week, the value of one share of bitcoin dropped below $18,000 from a high late last year of more than $64,000. The total crypto market value dropped from a peak of $3.2 trillion to below $1 trillion. 

“I’m definitely worried today,” Ryan said on Saturday as bitcoin reached its lowest point since December 2020. 

Still, Ryan maintained he still believes in bitcoin.

“I’m worried because we’ve got a war going on in Europe, huge amounts of inflation, we’re trying to recover from the impacts of a pandemic, and governments might try to regulate bitcoin,” he said. “But I’m not worried about bitcoin itself – I think it’s as solid as ever. That’s how cycles work and this could prove to be one of the best times in history to get into crypto.”

Casual cryptocurrency investors may not be so sure, but many seem willing to hold on to what they have in the hopes of a rebound. “Of course, when it rose to over $60,000, I had big dreams that I could earn enough money to go on a big trip or to make a down payment on a property,” said Joe Frisard, a semi-retired resident of Atlanta, Georgia.

The downturn has lowered Frisard’s ambitions, he acknowledged, but he still planned on hanging on to the cryptocurrency he hadn’t already sold when it was closer to its peak. “I’ve lost a good bit of money in the stock market, too,” he said, “but I’m not looking to dump my stocks. They’re a long-term investment and I see bitcoin in a similar way.”

Weathering the storm 

Gordon Henderson, a retired collegiate marching band director from Los Angeles, California, is also not panicking.

“I’m much more concerned about my stocks in my retirement fund than in my relatively small crypto holdings,” he said. Henderson remembers his father, at age 69 in 1987, converting his retirement fund to cash before a recession temporarily decimated the stock market.

“He was pretty proud of his timing,” Henderson recalled, “but in reality, he would have ended up with eight times more money if he had weathered the storm and kept his money in the stock market for another two decades. That’s how I look at cryptocurrency. I’ll hang onto it and maybe it will pay for college for my kids. If not, I was prepared for the loss.”

Colin Ash, an urban planner in New Orleans, Louisiana, has owned bitcoin for years, but said he thinks of it as “a fun gamble.”

“Of course, I wish I would have timed it perfectly and sold it all at the peak,” he said, “but it’s not realistic to think you can ever do that with any kind of investment. I think of it as something separate from the rest of my money. If something comes of it in the long run, then great. If not, at least I already sold some and paid off some debt.” 

For Hickey in San Diego, as well as many other investors, the key is to not invest more than you can afford to lose, particularly with an asset as speculative as cryptocurrency.

“Under the current circumstances, with everything falling so far down, I’ve decided to halt my weekly recurring purchase of bitcoin,” he said. “I think I’m done investing for now.”

He paused for a moment, and then said, “Now, that’s kind of hard, because if you want to make money you should buy low and sell high. Bitcoin prices are low, so I’ll probably be back in before you know it.”

Amazon and Cartier joined forces Wednesday in U.S. court to accuse a social media influencer of working with Chinese firms to sell knock-offs of the luxury brand’s jewelry on the e-commerce giant’s site. 

The online personality used sites like Instagram to pitch Cartier jewelry such as “Love bracelets” to followers and then provided links that led to counterfeit versions on Amazon, one of two lawsuits alleged. 

The influencer appeared to be a woman in Handan, China, and the merchants involved in the “counterfeiting scheme” were traced to other Chinese cities, according to court documents. 

“By using social media to promote counterfeit products, bad actors undermine trust and mislead customers,” Amazon associate general counsel Kebharu Smith said in a statement. 

“We don’t just want to chase them away from Amazon — we want to stop them for good,” Smith added. 

The Seattle-based e-commerce giant has booted vendors targeted in the suit from its platform and teamed with Cartier to urge a federal court to make them pay damages and legal costs for hawking knock-off jewelry there from June 2020 through June 2021. 

The “sophisticated campaign” sought to avoid detection by having the social media influencer pitch jewelry as being Cartier, but the vendors made no mention of the luxury brand at their shops at Amazon, the lawsuit said. 

Buyers, however, were sent jewelry bearing Cartier trademarks, the companies alleged in court documents. 

A second lawsuit accuses an Amazon store operating under the name “YFXF” last year of selling counterfeit Cartier goods, disguising jewelry as unbranded at the website but sending buyers knock-offs bearing the company’s trademark. 

Those involved in the scheme “advertised their counterfeit products on third-party social media websites by using ‘hidden links’ to direct their followers to the counterfeit Cartier products, while disguising the products as non-branded in the listings in the Amazon Store,” the lawsuit said. 

The companies said that Instagram direct messages and shared links were used to instruct social media followers about how to buy knock-offs at Amazon.

A new study has found that Facebook has failed to catch Islamic State group and al-Shabab extremist content in posts aimed at East Africa as the region remains under threat from violent attacks and Kenya prepares to vote in a closely contested national election. 

An Associated Press series last year, drawing on leaked documents shared by a Facebook whistleblower, showed how the platform repeatedly failed to act on sensitive content including hate speech in many places around the world. 

The new and unrelated two-year study by the Institute for Strategic Dialogue found Facebook posts that openly supported IS or the Somalia-based al-Shabab — even ones carrying al-Shabab branding and calling for violence in languages including Swahili, Somali and Arabic — were allowed to be widely shared. 

The report expresses particular concern with narratives linked to the extremist groups that accuse Kenyan government officials and politicians of being enemies of Muslims, who make up a significant part of the East African nation’s population. The report notes that “xenophobia toward Somali communities in Kenya has long been rife.” 

The al-Qaida-linked al-Shabab has been described as the deadliest extremist group in Africa, and it has carried out high-profile attacks in recent years in Kenya far from its base in neighboring Somalia. The new study found no evidence of Facebook posts that planned specific attacks, but its authors and Kenyan experts warn that allowing even general calls to violence is a threat to the closely contested August presidential election. 

Already, concerns about hate speech around the vote, both online and off, are growing. 

“They chip away at that trust in democratic institutions,” report researcher Moustafa Ayad told the AP of the extremist posts. 

The Institute for Strategic Dialogue found 445 public profiles, some with duplicate accounts, sharing content linked to the two extremist groups and tagging more than 17,000 other accounts. Among the narratives shared were accusations that Kenya and the United States are enemies of Islam, and among the posted content was praise by al-Shabab’s official media arm for the killing of Kenyan soldiers. 

Even when Facebook took down pages, they would quickly be reconstituted under different names, Ayad said, describing serious lapses by both artificial intelligence and human moderators. 

“Why are they not acting on rampant content put up by al-Shabab?” he asked. “You’d think that after 20 years of dealing with al-Qaida, they’d have a good understanding of the language they use, the symbolism.” 

He said the authors have discussed their findings with Facebook and some of the accounts have been taken down. He said the authors also plan to share the findings with Kenya’s government. 

Ayad said both civil society and government bodies such as Kenya’s national counterterrorism center should be aware of the problem and encourage Facebook to do more. 

Asked for comment, Facebook requested a copy of the report before its publication, which was refused. 

The company then responded with an emailed statement. 

“We’ve already removed a number of these pages and profiles and will continue to investigate once we have access to the full findings,” Facebook wrote Tuesday, not giving any name, citing security concerns. “We don’t allow terrorist groups to use Facebook, and we remove content praising or supporting these organizations when we become aware of it. We have specialized teams — which include native Arabic, Somali and Swahili speakers — dedicated to this effort.” 

Concerns about Facebook’s monitoring of content are global, say critics. 

“As we have seen in India, the United States, the Philippines, Eastern Europe and elsewhere, the consequences of failing to moderate content posted by extremist groups and supporters can be deadly, and can push democracy past the brink,” the watchdog The Real Facebook Oversight Board said of the new report, adding that Kenya at the moment is a “microcosm of everything that’s wrong” with Facebook owner Meta. 

“The question is, who should ask Facebook to step up and do its work?” asked Leah Kimathi, a Kenyan consultant in governance, peace and security, who suggested that government bodies, civil society and consumers all can play a role. “Facebook is a business. The least they can do is ensure that something they’re selling to us is not going to kill us.”

After 35 years of decline, the number of nuclear weapons in the world is set to rise in the coming decade as global tensions flare amid Russia’s war in Ukraine, researchers said Monday.  

The nine nuclear powers — Britain, China, France, India, Israel, North Korea, Pakistan, the United States and Russia — had 12,705 nuclear warheads in early 2022, or 375 fewer than in early 2021, according to estimates by the Stockholm International Peace Research Institute (SIPRI).   

The number has come down from a high of more than 70,000 in 1986, as the U.S. and Russia have gradually reduced their massive arsenals built up during the Cold War. 

But this era of disarmament appears to be coming to an end and the risk of a nuclear escalation is now at its highest point in the post-Cold War period, SIPRI researchers said. 

“Soon, we’re going to get to the point where, for the first time since the end of the Cold War, the global number of nuclear weapons in the world could start increasing for the first time,” Matt Korda, one of the co-authors of the report, told AFP. 

“That is really kind of dangerous territory.” 

After a “marginal” decrease seen last year, “nuclear arsenals are expected to grow over the coming decade,” SIPRI said. 

During the war in Ukraine, Russian President Vladimir Putin has on several occasions made reference to the use of nuclear weapons. 

Meanwhile several countries, including China and Britain, are either officially or unofficially modernizing or ramping up their arsenals, the research institute said. 

“It’s going to be very difficult to make progress on disarmament over the coming years because of this war, and because of how Putin is talking about his nuclear weapons,” Korda said. 

These worrying statements are pushing “a lot of other nuclear armed states to think about their own nuclear strategies,” he added. 

‘Nuclear war can’t be won’ 

Despite the entry into force in early 2021 of the U.N. nuclear weapon ban treaty and a five-year extension of the U.S.-Russian “New START” treaty, the situation has been deteriorating for some time, according to SIPRI. 

Iran’s nuclear program and the development of increasingly advanced hypersonic missiles have, among other things, raised concern. 

The drop in the overall number of weapons is due to the U.S. and Russia “dismantling retired warheads,” SIPRI noted, while the number of operational weapons remains “relatively stable.” 

Moscow and Washington alone account for 90% of the world’s nuclear arsenal. 

Russia remains the biggest nuclear power, with 5,977 warheads in early 2022, down by 280 from a year ago, either deployed, in stock or waiting to be dismantled, according to the institute. 

More than 1,600 of its warheads are believed to be immediately operational, SIPRI said. 

The United States meanwhile has 5,428 warheads, 120 fewer than last year, but it has more deployed than Russia, at 1,750. 

In terms of overall numbers, China comes third with 350, followed by France with 290, Britain with 225, Pakistan with 165, India with 160, and Israel with 90. 

Israel is the only one of the nine that does not officially acknowledge having nuclear weapons. 

As for North Korea, SIPRI said for the first time that Kim Jong Un’s Communist regime now has 20 nuclear warheads. 

Pyongyang is believed to have enough material to produce around 50. 

In early 2022, the five nuclear-armed permanent members of the United Nations Security Council — Britain, China, France, Russia and the U.S. — issued a statement that “nuclear war cannot be won and must never be fought.” 

Nonetheless, SIPRI noted, all five “continue to expand or modernize their nuclear arsenals and appear to be increasing the salience of nuclear weapons in their military strategies.” 

“China is in the middle of a substantial expansion of its nuclear weapons arsenal, which satellite images indicate includes the construction of over 300 new missile silos,” it said.  

According to the Pentagon, Beijing could have 700 warheads by 2027. 

Britain last year said it would increase the ceiling on its total warhead stockpile and would no longer publicly disclose figures for the country’s operational nuclear weapons.

Elon Musk accused Twitter of “actively resisting and thwarting his information rights,” as the Tesla founder attempts to get information about fake and spam accounts on the platform.

The accusation came in a letter Musk sent to Twitter Monday in which he warned he could walk away from the $44 billion deal to take over the company should Twitter not provide the information he seeks.

Musk further accused Twitter of a “clear material breach” of its obligation to provide the data.

“Musk believes Twitter is transparently refusing to comply with its obligations under the merger agreement, which is causing further suspicion that the company is withholding the requested data due to concern for what Musk’s own analysis of that data will uncover,” according to the letter.

“Twitter has, in fact, refused to provide the information that Mr. Musk has repeatedly requested since May 9, 2022, to facilitate his evaluation of spam and fake accounts on the company’s platform. Twitter’s latest offer to simply provide additional details regarding the company’s own testing methodologies, whether through written materials or verbal explanations, is tantamount to refusing Mr. Musk’s data requests,” the letter said.

The social media platform has not commented on Musk’s letter. Twitter stock tumbled over 5% in early trading Monday.

A crewless robotic boat that had tried to retrace the 1620 sea voyage of the Mayflower has finally reached the shores of North America — this time in Canada instead of the Massachusetts coast where its namesake landed more than 400 years ago. 

The sleek autonomous trimaran docked in Halifax, Nova Scotia, on Sunday, after more than five weeks crossing the Atlantic Ocean from England, according to tech company IBM, which helped build it. 

Piloted by artificial intelligence technology, the 50-foot (15-meter) Mayflower Autonomous Ship didn’t have a captain, navigator or human on board — though it might have helped to have a mechanic. 

“The technology that makes up the autonomous system worked perfectly, flawlessly,” said Rob High, an IBM computing executive involved in the project. “Mechanically, we did run into problems.” 

Trouble at sea

Its first attempt at the trans-Atlantic crossing to Plymouth, Massachusetts, in June 2021 was beset by technical glitches, forcing the boat to return to its home port of Plymouth, England. 

It set off again from England nearly a year later on April 27, bound for Virginia — but a generator problem diverted it to Portugal’s Azores islands, where a team member flew in to perform emergency repairs. More troubles on the open sea came in late May when the U.S.-bound boat developed a problem with the charging circuit for the generator’s starter batteries. 

AI software is getting better at helping self-driving machines understand their surroundings and pilot themselves, but most robots can’t heal themselves when the hardware goes awry. 

Nonprofit marine research organization ProMare, which worked with IBM to build the ship, switched to a back-up navigation computer on May 30 and charted a course to Halifax — which was closer than any U.S. destination. The boat’s webcam on Sunday morning showed it being towed by a larger boat as the Halifax skyline neared — a safety requirement under international maritime rules, IBM said.

Russia’s invasion of Ukraine appears to be having an unanticipated impact in cyberspace — a decrease in the number of ransomware attacks. 

“We have seen a recent decline since the Ukrainian invasion,” Rob Joyce, the U.S. National Security Agency’s director of cybersecurity, told a virtual forum Wednesday. 

Joyce said one reason for the decrease in ransomware attacks since the February 24 invasion is likely improved awareness and defensive measures by U.S. businesses. 

He also said some of it is tied to measures the United States and its Western allies have taken against Moscow in response to the war in Ukraine. 

“We’ve definitively seen the criminal actors in Russia complain that the functions of sanctions and the distance of their ability to use credit cards and other payment methods to get Western infrastructure to run these [ransomware] attacks have become much more difficult,” Joyce told The Cipher Brief’s Cyber Initiatives Group. 

“We’ve seen that have an impact on their [Russia’s] operations,” he added. “It’s driving the trend down a little bit.” 

Just days after Russian forces entered Ukraine, U.S. cybersecurity officials renewed their “Shields Up” awareness campaign, encouraging companies to take additional security precautions to protect against potential cyberattacks by Russia itself or by criminal hackers working on Moscow’s behalf. 

And those officials caution Russia still has the capability to inflict more damage in cyberspace. 

“Russia is continuing to explore options for potential cyberattacks,” the Cybersecurity and Infrastructure Security Agency’s Matthew Hartman told a meeting of the U.S. Chamber of Commerce last week. 

“We are seeing glimpses into targeting and into access development,” Hartman said, noting Russia has for now held back from launching any major cyberattacks against the West. “We do not know at what point a calculus may change.” 

FBI cyber officials have likewise voiced concern that it could be a matter of time before the Kremlin authorizes cyberattacks targeting U.S. critical infrastructure, including against the energy, finance and telecommunication sectors. 

U.S. and NATO officials on Wednesday also cautioned that it would be a mistake to think that just because there have been few signs of “catastrophic effects” that Russia has not tried to leverage its cyber capabilities to its advantage. 

“It has been happening and it’s still happening,” said Stefanie Metka, head of the Cyber Threat Analysis Branch at NATO. “There’s a lot of cyber activity that’s happening all the time and probably we won’t know the full extent of it until we turn the computers back on.”  

Said the NSA’s Joyce: “If you look at Ukraine, they have been heavily targeted. What we’ve seen are a number of wiper viruses, seven or eight different or unique wiper viruses that have been thrown into the ecosystem of Ukraine and its near abroad.” Wiper viruses are viruses that erase a computer’s memory.

These included a cyberattack against a satellite communications company, which hampered the ability of Ukraine’s military to communicate and had spillover effects across Europe. 

But with help from the U.S. and other allies, Ukraine was able to mitigate the impact, Joyce said. 

“The Ukrainians have been under threat and under pressure for a number of years, and so they have continued to adapt and improve and develop their tradecraft to the point where they mount a good defense and, equally as important, they mount a great incident response,” he said.  

Some cybersecurity experts say that ability to respond might be one of the biggest take-aways, so far, from the invasion. 

“Resiliency matters,” said Dmitri Alperovitch, the founder of the Silverado Policy Accelerator and the former chief technology officer of cybersecurity firm CrowdStrike, at Wednesday’s virtual forum. “The Ukrainians have gotten really, really good at rebuilding networks, quickly mitigating damage.” 

Another key lesson, he said, is the limitations of cyber. 

“If you’ve got kinetic options, if you can create a crater somewhere, take out a substation, take out a communication system, that’s what you’re going to prefer to use,” Alperovitch said. “That’s what’s easiest [to do] to get lasting damage.”
