• U.S. Disrupts North Korea Ransomware Group, Recovers Nearly Half a Million

    U.S. law enforcement authorities have disrupted a group of North Korean hackers, recovering nearly half a million dollars in ransom payments it received from a Kansas hospital, a Colorado health care provider and other victims. The North Korea state-sponsored cybercriminals encrypted the Kansas hospital’s servers in May 2021, demanding ransom in exchange for regaining access to its critical computer networks.

  • New Computing Security Architecture Protects Sensitive Private Data

    Protecting sensitive information on the internet has become an essential feature for computing architectures. Applications that process such data must trust the system software they rely on, such as operating systems and hypervisors, but such system software is complex and often has vulnerabilities that can risk data confidentiality and integrity.

  • Safer Web Surfing with a New Method for Detecting Malicious Code Patterns

    With the ever-increasing importance of the Internet in our lives, there are growing attempts to exploit software vulnerabilities in our PCs for personal benefit. One way to do so is by infecting the victim’s PC with a malicious code injected through a website. A fast and reliable detection approach can analyze distribution patterns of malicious codes in websites.

  • Protecting Computer Vision from Adversarial Attacks

    Advances in computer vision and machine learning have made it possible for a wide range of technologies to perform sophisticated tasks with little or no human supervision — from autonomous drones and self-driving cars to medical imaging and product manufacturing. Engineers are developing methods to keep these autonomous machines and devices from being hacked.

  • These Red Flags Can Let You Know When You’re in an Online Echo Chamber

    Online echo chambers are virtual spaces that gather like-minded individuals. Research has shown that people are more likely to believe and share information they encounter in these spaces, because it confirms their existing beliefs. Somesocial media users who routinely engage in this style of communication also spread disinformation.

  • The Chinese Military’s Access to AI Chips

    The Chinese military has made rapid progress in artificial intelligence. This progress largely depends on continued access to high-end semiconductors designed by American companies and produced in Taiwan and South Korea. The aggressive moves by the Trump and Biden administrations to limit technology exports to the Chinese military notwithstanding, China continues to order large quantities of American-designed advanced semiconductors from manufacturers in Taiwan and South Korea.

  • Russian Disinformation Campaign Aims to Divide, Weaken Western Coalition

    A new report reviews ongoing Russian influence efforts aimed at undermining and dividing the Western defensive coalition supporting Ukraine, as well as influencing public opinion of Russia’s war against Ukraine favorably toward Russia.

  • NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

    NIST has chosen the first group of encryption tools that are designed to withstand the assault of a future quantum computer, which could potentially crack the security used to protect privacy in the digital systems we rely on every day — such as online banking and email software.

  • Cyberproofing Small and Medium Businesses -- a Small Step with a Big Impact

    Small businesses are not immune to cybersecurity incidents. In fact, they’re often more vulnerable because they lack the time, resources and sometimes the skills to prepare for and defend against an attack, or to mitigate and remedy any consequences. In Australia, they created a tool to help businesses quickly and easily test the security of their websites.

  • How Does the U.S. Power Grid Work?

    Responsible for powering the country and its economy, the U.S. energy grid has come under increasing strain due to climate change, and the threat of cyberattacks looms. The U.S. electric grid brings power to millions of homes and businesses via a vast network of transmission and distribution lines. Experts say the grid is increasingly vulnerable to extreme weather events, such as the February 2021 Texas winter storms, and cyberattacks. President Biden has proposed overhauling the grid, but his plans could face legal and political hurdles.

  • China’s Disinformation Campaign Against Rare Earth Processing Facilities

    China dominates the production and processing of rare-earth elements (REEs). In order to lessen this dependence on the critical minerals, the U.S. government has been supporting the development of U.S. REE sources. China has been trying to prevent this shift by launching a disinformation campaign: China’ intelligence services have created social media accounts of fake local environmentalists who spread disinformation to local communities about the REE facilities being built nearby.

  • I Watched Hundreds of Flat-Earth Videos to Learn How Conspiracy Theories Spread – and What It Could Mean for Fighting Disinformation

    About 11% of Americans believe the Earth might be flat. It is tempting to dismiss “flat Earthers” as mildly amusing, but we ignore their arguments at our peril. Polling shows that there is an overlap between conspiracy theories, some of which can act as gateways for radicalization. QAnon and the great replacement theory, for example, have proved deadly more than once.

  • Technology Can Detect Fake News in Videos

    Social media represent a major channel for the spreading of fake news and disinformation. This situation has been made worse with recent advances in photo and video editing and artificial intelligence tools, which make it easy to tamper with audiovisual files, for example with so-called deepfakes, which combine and superimpose images, audio and video clips to create montages that look like real footage.

  • Hate Sites: Using the Broader Abortion Argument to Spread Racism, Extremism

    Racially or ethnically motivated violent extremists are using the debate around women’s reproductive rights to promote racist and extremist agendas.

  • The Strategic Relevance of Cybersecurity Skills

    Evidence suggests there is a global cybersecurity skills shortage affecting businesses and governments alike, which means that organizations are struggling to fill their cybersecurity vacancies. Tommaso De Zan writes that “the absence of cybersecurity experts protecting national critical infrastructures constitutes a national security threat, a loophole that may be exploited by malicious actors.”
