Targeted cyber-espionage does not always begin with a technical exploit. For journalists, activists and other high-risk individuals, attackers can spend considerable time studying their...

Modern military units are becoming increasingly dependent on electricity. Drones need regular charging, electronic warfare equipment can draw substantial power, and edge-computing systems must...

As wireless networks become faster and more demanding, the tiny radio-frequency chips inside smartphones and communication systems are approaching their physical limits. Acoustic wave...

As organizations begin deploying teams of AI agents to handle complex tasks, cybersecurity is becoming a growing concern. In these multi-agent systems, several large...

Protecting critical systems becomes especially difficult once an attacker gets inside the device itself. Conventional cybersecurity tools can monitor network traffic, identify known vulnerabilities...

Modern military operations depend heavily on satellite navigation, secure communications and precise timing. That dependence creates vulnerabilities: GPS and other satellite signals can be...

End-to-end encryption can keep the contents of a conversation private, but it cannot protect users if an attacker manages to take over the account...

Persistent surveillance is one of the biggest challenges in modern military operations. Conventional drones are limited by battery capacity or fuel, requiring frequent landings...

As wireless networks carry ever-growing amounts of data, communication systems face increasing pressure to transmit information faster while consuming less power and bandwidth. This...

Modern military operations are influenced by more than events on the physical battlefield. Social media posts, messaging platforms, videos, news reports and foreign-language sources...

Countering small drones has become increasingly difficult as unmanned aircraft grow smaller, cheaper, and more numerous. Traditional radar systems can detect many aerial threats,...

Every new generation of wireless technology places greater demands on the chips inside smartphones, base stations and connected vehicles. As 5G evolves toward 6G,...

Smartphones separate their cellular modem from the main operating system partly to prevent problems in one component from compromising the entire device. New security...

As wireless devices continue to multiply, the radio spectrum is becoming increasingly crowded. Smartphones, connected vehicles, industrial sensors, wearables and countless other devices all...

As military and commercial operations become increasingly dependent on satellite communications, protecting those links from interference has become a growing challenge. Modern electronic warfare...

Modern military communications systems face a persistent challenge: every network, radio, satellite link, and data channel experiences different types of interference, signal degradation, and...

Mobile communications have become essential for modern military organizations, but they also create a security challenge. Smartphones and tablets offer flexibility and rapid access...

Satellites have become a critical part of modern military operations, providing communications, navigation, intelligence and targeting data to forces around the world. As dependence...

As drones become increasingly common along national borders and around critical infrastructure, detecting them is only part of the challenge. Border security agencies also...

Wireless networks are expected to support far more than smartphones in the coming decade. Autonomous vehicles, industrial automation, critical infrastructure, and AI-driven services will...

Modern electronic warfare depends on the ability to detect, identify, and analyze electromagnetic signals quickly. As military communications, radars, and sensors become more numerous...

Cybersecurity advice is only effective if people understand it. Organizations routinely warn users about phishing, malware, trojans, and viruses, expecting those terms to communicate...
