• Fastly Global Internet Outage: Why Did So Many Sites Go Down — and What Is a CDN, Anyway?

    If you were having difficulty accessing your favorite website on Tuesday time, you’re not alone. A jaw-dropping number of major websites around the globe suddenly became unavailable with no immediately obvious explanation — before reappearing an hour later. To understand why it happened, you need to know what a CDN (content delivery network) is and how crucial they are to the smooth running of the internet.

  • Americans Bought 1.6 Million Guns Last Month. Who Were the Buyers?

    Americans bought 1.6 million guns last month – an impressive number, but only the 14th highest on record, and still down 18 percent from May 2020. What has remained far more opaque is who exactly was doing the buying last year. This week, we started to have a more definitive answer.

  • White House Urges US Companies to Protect Against Ransomware

    The White House on Thursday urged American businesses to take new precautions to combat disruptive ransomware attacks that have increasingly hobbled companies throughout Western economies. Anne Neuberger, a White House cybersecurity official, said in a statement that the “most important takeaway” from the recent attacks, including those affecting a key gasoline pipeline and a meat production company in the U.S., is that “companies that view ransomware as a threat to their core business operations rather than a simple risk of data theft will react and recover more effectively.”

  • China’s Determined Effort to Build an S&T Infrastructure

    For half a century, China, with dogged determination, has pursued its effort to build an S&T infrastructure. A new report from the Center for Security and Emerging Technology (CSET) notes that foreign technology acquisition continues to play a large role in this effort, with commercial technology products becoming increasingly attractive targets. Beijing’s “hybrid innovation system” blends forms of academic collaboration, industry partnerships, cyber espionage, direct investment, and influence operations to enhance China’s comprehensive national power.

  • Cyber Attacks Can Shut Down Critical Infrastructure. It’s Time to Make Cyber Security Compulsory

    The 7 May attack on the Colonial Pipeline highlights how vulnerable critical infrastructure such as fuel pipelines are in an era of growing cyber security threats. In Australia, we believe the time has come to make it compulsory for critical infrastructure companies to implement serious cyber security measures.

  • It’s Time to Surge Resources into Prosecuting Ransomware Gangs

    In the popular imagination, hacking is committed by lone wolves with exceptional computer skills. But in reality, the vast majority of hackers do not have the technical sophistication to create the malicious tools that are essential to their trade. Kellen Dwyer writes that hacking has exploded in recent years because criminals have specialized and subspecialized so that each one can concentrate on facilitating just a single phase of a successful data breach. This is known as cybercrime-as-a-service and it is a massive business. This intricate cybercrime ecosystem offers the key to fighting it: “While organization and specialization are strengths of cybercriminals, they are also weaknesses. That means there are organizations that can be infiltrated and exploited.”

  • Rare Earth Supply Disruptions Have Long-Range Impacts

    Rare earth materials are essential to a variety of industries. From phones to fighter jets, a range of devices and machines rely on rare earth elements that are mined and refined largely in China. Disruptions to this supply can have wide-ranging consequences, but the understanding of how those disruptions play out in global markets is limited. A new study from explores the effects of supply disruptions such as mine shutdowns.

  • Engineers and Economists Prize Efficiency, but Nature Favors Resilience – Lessons from Texas, COVID-19 and the 737 Max

    The damage from Winter Storm Uri, the economic devastation from the COVID-19 pandemic and the fatal Boeing 737 Max accidents show the price society pays for a relentless pursuit of efficiency. Modern society has prioritized free-market economics and efficient computer systems to the detriment of other priorities. Studies of algorithms show that efficiency can come at a high cost. Sexual reproduction and car insurance highlight the benefits of resilience.

  • Tips and Tactics for Dealing with Ransomware

    Used in cyberattacks that can paralyze organizations, ransomware is malicious software that encrypts a computer system’s data and demands payment to restore access. To help organizations protect against ransomware attacks and recover from them if they happen, NIST has published an infographic offering a series of simple tips and tactics.

  • Can the West Devise an Alternative to China's Belt and Road?

    Since it was announced by Chinese President Xi Jinping in 2013, Beijing’s Belt and Road Initiative (BRI) has channeled hundreds of billions of dollars into foreign infrastructure, boosting trade, and clearing the way for China to forge political and economic links around the world. But a combination of growing disillusionment among partner countries with the resulting projects, room for more investment, and increased unease about the strategic implications of the BRI might have opened the door for an alternative to emerge.

  • The U.S. Is Trying to Reclaim Its Rare-Earth Mantle

    Rare earths elements (REEs) are used in cancer treatment and electric engines, telescope lenses and TVs, cellphones and fighter jets. Many REEs are extracted and refined almost entirely in China. The U.S. was 100% net import reliant on rare-earth elements in 2018, importing an estimated 11,130 metric tons of compounds and metals valued at $160 million. The Department of Energy is funding research to make separating rare earths easier and more efficient, and to promote recycling. “There is a clock ticking in the background of this race for a rare-earth supply chain. There is a danger that the electric vehicle market, which will demand large quantities of critical minerals including rare earths, may move faster than the rare-earth supply chain, which would feed it,” Sabri Ben-Achour writes.

  • Hydropower’s Evolving Value to the Grid and Energy Storage

    Across the United States, hydroelectric dams are capturing energy from river water to create electricity that powers everything from street lights to mega industrial plants. Hydropower represents 41 percent of all renewable energy generated across the nation and is a key element of a flexible, resilient electric grid. But in some parts of the country, operations at dams are changing.

  • Supply Chains and National Security—the Lessons of the COVID-19 Pandemic

    National power relies on globally efficient and intertwined supply chains. These highly interconnected supply chains are a fact of life, bringing benefit and vulnerability. Supply chain vulnerability stretches across whole sectors of the U.S. economy and is a national security issue in that sense: a set of interests that if disrupted could directly affect the health and well-being of the United State and its allies.

  • Huawei’s Ability to Eavesdrop on Dutch Mobile Users Is a Wake-up Call for the Telecoms Industry

    Chinese technology provider Huawei was recently accused of being able to monitor all calls made using Dutch mobile operator KPN. While the full report on the issue has not been made public, journalists reporting on the story have outlined specific concerns that Huawei personnel in the Netherlands and China had access to security-essential parts of KPN’s network – including the call data of millions of Dutch citizens – and that a lack of records meant KPN couldn’t establish how often this happened.

  • The Liberals Who Can’t Quit Lockdown

    Among the relieved Americans going back out to restaurants and planning their summer-wedding travel is a different group, Emma Green writes: liberals who aren’t quite ready to let go of pandemic restrictions. “For this subset, diligence against COVID-19 remains an expression of political identity—even when that means overestimating the disease’s risks or setting limits far more strict than what public-health guidelines permit.” For many progressives, extreme vigilance was in part about opposing Donald Trump - but the spring of 2021 is different from the spring of 2020, as scientists know a lot more about how COVID-19 spreads—and how it doesn’t. “Public-health advice is shifting. But some progressives have not updated their behavior based on the new information,” Green says.
