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.

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.”

Insights into Blockchain Vulnerabilities
Distributed ledger technology, such as blockchains, has become more prevalent across a variety of contexts over the past decade. The premise is that blockchains operate securely without any centralized control and that they are immutable or unsusceptible to change. New report details how centralization can be introduced, affecting security.

The Risk of Russian Cyber Retaliation for the United States Sending Rockets to Ukraine
U.S. rocket shipments to Ukraine will not trigger Russian cyberattacks against the United States. Russian is too focused on attacking Ukrainian systems and defending their own networks to mount a response to the weapons shipments.

Can Reforming Social Media Save American Democracy?
When social media exploded in the mid-2000s, retweeting, sharing and liking posts appeared to give average citizens the power to share their opinions far and wide. The problem, according to social psychologist Jonathan Haidt, is that online social networks didn’t really end up giving everyone the voice that many thought it would. “It empowered four groups who take advantage of the viral dynamics of social media. That is the far right, the far left, trolls and Russian intelligence,” he says.

“Hacking” Solutions for Pressing Cybersecurity Challenges
When people think about the game capture the flag, memories of gym class or family trips likely come to mind. Researchers are participating in a slightly different version of this childhood favorite, where teams face off against opponents across the world to tackle real-world cybersecurity issues.

Cybersecurity Tools to Protect Solar, Wind Power on the Grid
Solar panels and wind turbines are projected to produce 44% of America’s electricity by 2050, but they present cybersecurity challenges. They have sensors, controllers, actuators or inverters which are directly or indirectly connected to the internet using insecure connectivity to legacy electric grid systems. They have complex physics. They’re subject to advanced persistent threats. And there will be more and more of them going online.

States Rush to Combat AI Threat to Elections
By Zachary Roth
This year’s presidential election will be the first since generative AI became widely available. That’s raising fears that millions of voters could be deceived by a barrage of political deepfakes. Congress has done little to address the issue, but states are moving aggressively to respond — though questions remain about how effective any new measures to combat AI-created disinformation will be.
Ransomware Attacks: Death Threats, Endangered Patients and Millions of Dollars in Damages
By Dino Jahic
A ransomware attack on Change Healthcare, a company that processes 15 billion health care transactions annually and deals with 1 in 3 patient records in the United States, is continuing to cause massive disruptions nearly three weeks later. The incident, which started on February 21, has been called the “most significant cyberattack on the U.S. health care system” by the American Hospital Association. It is just the latest example of an increasing trend.
Chinese Government Hackers Targeted Critics of China, U.S. Businesses and Politicians
An indictment was unsealed Monday charging seven nationals of the People’s Republic of China (PRC) with conspiracy to commit computer intrusions and conspiracy to commit wire fraud for their involvement in a PRC-based hacking group that spent approximately 14 years targeting U.S. and foreign critics, businesses, and political officials in furtherance of the PRC’s economic espionage and foreign intelligence objectives.
Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
By Trina West
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
