“Half of Twitter’s roughly 7,000 full-time workers have complete access to its code and user confidential data” Says its former chief security officer Peiter Zatko

Twitter executives misled federal regulators and the company’s own board about “extreme and egregious shortcomings” in its defenses against hackers and its meager efforts to combat bots, said a former chief security officer Peiter Zatko.

Why composability is key to scaling digital twins

Posted by in categories: business, security, sustainability

Digital twins enable enterprises to model and simulate buildings, products, manufacturing lines, facilities and processes. This can improve performance, quickly flag quality errors and support better decision-making. Today, most digital twin projects are one-off efforts. A team may create one digital twin for a new gearbox and start all over when modeling a wind turbine that includes this part or the business process that repairs this part.

Ideally, engineers would like to quickly assemble more complex digital twins to represent turbines, wind farms, power grids and energy businesses. This is complicated by the different components that go into digital twins beyond the physical models, such as data management, semantic labels, security and the user interface (UI). New approaches for composing digital elements into larger assemblies and models could help simplify this process.

DARPA seeks AI solutions for sourcing critical minerals

Posted by in categories: robotics/AI, security

DARPA has launched a competition to find AI solutions that can help with sourcing critical minerals.

Critical minerals are raw, non-fuel materials that are vital for manufacturing products that are essential to national security.

DARPA is teaming up with the US Geological Survey (USGS) to explore how machine learning and AI can accelerate critical mineral assessments.

Asteroid Bennu: Will the best-characterized asteroid in the solar system hit the Earth or not?

Posted by in categories: particle physics, security, space

Asteroid Bennu was in the news recently for an astonishing discovery. NASA scientists revealed that the asteroid has a surface that appears similar to plastic balls. The discovery dates back to October 2020, when NASA successfully collected a sample from the asteroid.

During the sampling event, the sampling head of the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) spacecraft had sunk by 1.6 feet (0.5 meters) into the surface of the asteroid. The space agency found that Bennu’s exterior is made of loosely packed particles that are haphazardly packed together. The spacecraft would have sunk right into the asteroid if it hadn’t fired its thruster to back away after collecting dust and rocks.

AI-designed camera only records objects of interest while being blind to others

Posted by in categories: encryption, information science, mobile phones, robotics/AI, security, surveillance, transportation

Over the past decade, digital cameras have been widely adopted in various aspects of our society, and are being massively used in mobile phones, security surveillance, autonomous vehicles, and facial recognition. Through these cameras, enormous amounts of image data are being generated, which raises growing concerns about privacy protection.

Some existing methods address these concerns by applying algorithms to conceal sensitive information from the acquired images, such as image blurring or encryption. However, such methods still risk exposure of sensitive data because the raw images are already captured before they undergo digital processing to hide or encrypt the sensitive information. Also, the computation of these algorithms requires additional power consumption. Other efforts were also made to seek solutions to this problem by using customized cameras to downgrade the image quality so that identifiable information can be concealed. However, these approaches sacrifice the overall for all the objects of interest, which is undesired, and they are still vulnerable to adversarial attacks to retrieve the that is recorded.

A new research paper published in eLight demonstrated a new paradigm to achieve privacy-preserving imaging by building a fundamentally new type of imager designed by AI. In their paper, UCLA researchers, led by Professor Aydogan Ozcan, presented a smart design that images only certain types of desired objects, while instantaneously erasing other types of objects from its images without requiring any digital processing.

US Space Force tests robot dogs to patrol Cape Canaveral

Posted by in categories: robotics/AI, security, space

The quadrupedal robots are well suited for repetitive tasks.


Mankind’s new best friend is coming to the U.S. Space Force.

The Space Force has conducted a demonstration using dog-like quadruped unmanned ground vehicles (Q-UGVs) for security patrols and other repetitive tasks. The demonstration used at least two Vision 60 Q-UGVs, or “robot dogs,” built by Ghost Robotics and took place at Cape Canaveral Space Force Station on July 27 and 28.

Microsoft blocks UEFI bootloaders enabling Windows Secure Boot bypass

Posted by in categories: computing, security

Some signed third-party bootloaders for the Unified Extensible Firmware Interface (UEFI) could allow attackers to execute unauthorized code in an early stage of the boot process, before the operating system loads.

Vendor-specific bootloaders used by Windows were found to be vulnerable while the status of almost a dozen others is currently unknown.

Threat actors could exploit the security issue to establish persistence on a target system that cannot be removed by reinstalling the operating system (OS).

Hydrophobic Ice More Common than Thought

Posted by in categories: biotech/medical, finance, mobile phones, robotics/AI, security

Researchers have observed the formation of 2D ice on gold surfaces that were thought to be too hydrophilic and too rough to support this type of ice.


Mobile devices use facial recognition technology to help users quickly and securely unlock their phones, make a financial transaction or access medical records. But facial recognition technologies that employ a specific user-detection method are highly vulnerable to deepfake-based attacks that could lead to significant security concerns for users and applications, according to new research involving the Penn State College of Information Sciences and Technology.

Deepfakes expose vulnerabilities in certain facial recognition technology

Posted by in categories: biotech/medical, finance, mobile phones, robotics/AI, security

Mobile devices use facial recognition technology to help users quickly and securely unlock their phones, make a financial transaction or access medical records. But facial recognition technologies that employ a specific user-detection method are highly vulnerable to deepfake-based attacks that could lead to significant security concerns for users and applications, according to new research involving the Penn State College of Information Sciences and Technology.

The researchers found that most that use facial liveness verification—a feature of that uses computer vision to confirm the presence of a live user—don’t always detect digitally altered photos or videos of individuals made to look like a live version of someone else, also known as deepfakes. Applications that do use these detection measures are also significantly less effective at identifying deepfakes than what the app provider has claimed.

“In recent years we have observed significant development of facial authentication and verification technologies, which have been deployed in many security-critical applications,” said Ting Wang, associate professor of information sciences and technology and one principal investigator on the project. “Meanwhile, we have also seen substantial advances in deepfake technologies, making it fairly easy to synthesize live-looking facial images and video at little cost. We thus ask the interesting question: Is it possible for malicious attackers to misuse deepfakes to fool the facial verification systems?”
