• Aiding Evaluation of Adversarial AI Defenses

    There are many inherent weaknesses that underlie existing machine learning (ML) models, opening the technology up to spoofing, corruption, and other forms of deception. Evaluation testbed, datasets, tools developed on GARD program were released to jump-start community and encourage creation of more robust defenses against attacks on ML models.

  • What Is Log4j? A Cybersecurity Expert Explains the Latest Internet Vulnerability, How Bad It Is and What’s at Stake

    Log4Shell, an internet vulnerability that affects millions of computers, involves an obscure but nearly ubiquitous piece of software, Log4j. So what is this humble piece of internet infrastructure, how can hackers exploit it and what kind of mayhem could ensue?

  • CISA Hosts Cybersecurity Navigators Forum for Election Officials

    CISA recently concluded a forum for state and local election officials to discuss cyber navigator programs. Cyber navigators are state liaisons that can help under-resourced local jurisdictions manage their cyber risks, help sort through the onslaught of risk information, advice, and available services, and help fast-track mitigation efforts. DHS is currently in the midst of its “Election Security” sprint, focused on the need to cement the resilience of the nation’s democratic infrastructures and protect the integrity of its election.

  • Computer Attacks with Laser Light

    Computer systems that are physically isolated from the outside world (air-gapped) can still be attacked. This is demonstrated by IT security experts in the LaserShark project. The researchers demonstrate hidden communication into air-gapped computer systems: Data transmitted to light-emitting diodes of regular office devices.

  • Far Too Little Vote Fraud to Tip Election to Trump, AP Finds

    >The Associated Press conducted a thorough review of every potential case of voter fraud in the six battleground states disputed by former President Donald Trump.Joe Biden won the 79 Electoral College votes of these states by a combined 311,257 votes out of 25.5 million ballots cast for president. The AP comprehensive review has found fewer than 475 potential fraud cases. The cases could not throw the outcome into question even if all the potentially fraudulent votes were for Biden, which they were not, and even if those ballots were actually counted, which in most cases they were not.

  • Securing U.S. Democracy

    Most of the homeland security architecture built in the past twenty years has been devoted to protecting Americans from an act of international terrorism. Carrie Cordero writes that as a result, Americans are safer than they were twenty years ago from a terrorist attack directed or inspired by foreign groups on U.S. soil. She says, though, that more significantly, the threats to American safety and security have compounded in the past two decades. “These disparate threats and circumstances have challenged the effectiveness of the homeland security enterprise.”

  • What's the Deal with the Log4Shell Security Nightmare?

    What started out as a Minecraft prank, has now resulted in a 5-alarm security panic as administrators and developers around the world desperately try to fix and patch systems before the cryptocurrency miners, ransomware attackers and nation-state adversaries rush to exploit thousands of software packages. Nicholas Weaver writes that “Not only does the vulnerability affect thousands of programs but the exploitation of this vulnerability is very straightforward.  Attackers are already starting to launch widespread attacks.  Further compounding the problem is the huge diversity of vulnerable systems, so those responsible for defending systems are going to have a very bad Christmas.”

  • How China Could Cyberattack Taiwan

    China has the means to launch a disabling cyberattack against political rival Taiwan ahead of any military invasion, experts say, as the technology is already targeting the island’s political leadership. A straight-up military invasion would cost lives and mobilize U.S. forces for Taiwan’s defense. Disruptive cyberattacks could sow chaos and soften Taiwan’s defenses, potentially making an invasion less costly for Beijing, experts say.

  • New Cyber Protections against Stealthy “Logic Bombs”

    Cybersecurity researchers proposed new ways to protect 3D printed objects such as drones, prostheses, and medical devices from stealthy “logic bombs.”

  • Gait Authentication to Enhance Smartphone Security

    Real-world tests have shown that gait authentication could be a viable means of protecting smartphones and other mobile devices from cyber crime. A study showed that a method sensing an individual’s gait was on average around 85 percent accurate in recognizing the individual.

  • Detecting Malicious Broadcast Receivers

    The Android operating system has a large share of the mobile market and as such is a target for malware creators and other third parties who would manipulate the system for personal gain. So how might we enhance the detection of malware on the Android operating system commonly used to run mobile phones and tablets?

  • Using Math to Prove Computer Security

    An academic mathematician thought maths was boring, but he now relies on it to secure critical systems like those of the Australian Department of Defense against hackers.

  • Boosting Resilience of U.S. Timekeeping

    The U.S. should bolster research and development of systems that distribute accurate time via fiber-optic cable and radio as part of the effort to back up GPS and enhance the resilience of critical infrastructure that depends on it.

  • Stacked Deep Learning: Deeper Defense against Cyberattacks

    Internet-based industrial control systems are widely used to monitor and operate factories and critical infrastructure. Moving these systems online has made them cheaper and easier to access, but it has also made them more vulnerable to attack. Stacked deep learning offers a better way to detect hacking into industrial control systems. 

  • University of Central Florida Students Defend Virtual Energy System to Win CyberForce Competition

    The Knights of the University of Central Florida won the DOE’s CyberForce Competition, valiantly defending and securing a hydropower energy system against a malicious virtual cyberattack. The event challenged 120 teams from 105 colleges and universities to thwart a simulated cyberattack.
