with Microsoft’s unveiling of the new Security Copilot AI at its inaugural Microsoft Secure event. The automated enterprise-grade security system is powered by OpenAI’s GPT-4, runs on the Azure infrastructure and promises admins the ability “to move at the speed and scale of AI.”
Security Copilot is similar to the large language model (LLM) that drives the Bing Copilot feature, but with a training geared heavily towards network security rather than general conversational knowledge and web search optimization. […]
“Just since the pandemic, we’ve seen an incredible proliferation [in corporate hacking incidents],”Jakkal told Bloomberg. For example, “it takes one hour and 12 minutes on average for an attacker to get full access to your inbox once a user has clicked on a phishing link. It used to be months or weeks for someone to get access.”
[…]
Jakkal anticipates these new capabilities enabling Copilot-assisted admins to respond within minutes to emerging security threats, rather than days or weeks after the exploit is discovered. Being a brand new, untested AI system, Security Copilot is not meant to operate fully autonomously, a human admin needs to remain in the loop. “This is going to be a learning system,” she said. “It’s also a paradigm shift: Now humans become the verifiers, and AI is giving us the data.”
To more fully protect the sensitive trade secrets and internal business documents Security Copilot is designed to protect, Microsoft has also committed to never use its customers data to train future Copilot iterations. Users will also be able to dictate their privacy settings and decide how much of their data (or the insights gleaned from it) will be shared. The company has not revealed if, or when, such security features will become available for individual users as well.
American university researchers have developed a novel attack called “Near-Ultrasound Inaudible Trojan” (NUIT) that can launch silent attacks against devices powered by voice assistants, like smartphones, smart speakers, and other IoTs.
The team of researchers consists of professor Guenevere Chen of the University of Texas in San Antonio (UTSA), her doctoral student Qi Xia, and professor Shouhuai Xu of the University of Colorado (UCCS).
The team demonstrated NUIT attacks against modern voice assistants found inside millions of devices, including Apple’s Siri, Google’s Assistant, Microsoft’s Cortana, and Amazon’s Alexa, showing the ability to send malicious commands to those devices.
Inaudible attacks
The main principle that makes NUIT effective and dangerous is that microphones in smart devices can respond to near-ultrasound waves that the human ear cannot, thus performing the attack with minimal risk of exposure while still using conventional speaker technology.
In a post on USTA’s site, Chen explained that NUIT could be incorporated into websites that play media or YouTube videos, so tricking targets into visiting these sites or playing malicious media on trustworthy sites is a relatively simple case of social engineering.
The researchers say the NUIT attacks can be conducted using two different methods.
The first method, NUIT-1, is when a device is both the source and target of the attack. For example, an attack can be launched on a smartphone by playing an audio file that causes the device to perform an action, such as opening a garage door or sending a text message.
The other method, NUIT-2, is when the attack is launched by a device with a speaker to another device with a microphone, such as a website to a smart speaker.
A mammoth meatball has been created by a cultivated meat company, resurrecting the flesh of the long-extinct animals.
The project aims to demonstrate the potential of meat grown from cells, without the slaughter of animals, and to highlight the link between large-scale livestock production and the destruction of wildlife and the climate crisis.
The mammoth meatball was produced by Vow Food, an Australian company, which is taking a different approach to cultured meat.
There are scores of companies working on replacements for conventional meat, such as chicken, pork and beef. But Vow Foods is aiming to mix and match cells from unconventional species to create new kinds of meat.
The company has already investigated the potential of more than 50 species, including alpaca, buffalo, crocodile, kangaroo, peacocks and different types of fish.
The first cultivated meat to be sold to diners will be Japanese quail, which the company expects will be in restaurants in Singapore this year.
“We have a behaviour change problem when it comes to meat consumption,” said George Peppou, CEO of Vow Food.
“The goal is to transition a few billion meat eaters away from eating [conventional] animal protein to eating things that can be produced in electrified systems.
“And we believe the best way to do that is to invent meat. We look for cells that are easy to grow, really tasty and nutritious, and then mix and match those cells to create really tasty meat.”
Tim Noakesmith, who cofounded Vow Food with Peppou, said: “We chose the woolly mammoth because it’s a symbol of diversity loss and a symbol of climate change.” The creature is thought to have been driven to extinction by hunting by humans and the warming of the world after the last ice age.

Cultivated meat – chicken from Good Meat – is currently only sold to consumers in Singapore, but two companies have now passed an approval process in the US.
Vow Food worked with Prof Ernst Wolvetang, at the Australian Institute for Bioengineering at the University of Queensland, to create the mammoth muscle protein. His team took the DNA sequence for mammoth myoglobin, a key muscle protein in giving meat its flavour, and filled in the few gaps using elephant DNA.
This sequence was placed in myoblast stem cells from a sheep, which replicated to grow to the 20bn cells subsequently used by the company to grow the mammoth meat.
“It was ridiculously easy and fast,” said Wolvetang. “We did this in a couple of weeks.” Initially, the idea was to produce dodo meat, he said, but the DNA sequences needed do not exist.

Seren Kell, at the Good Food Institute Europe, said: “I hope this fascinating project will open up new conversations about cultivated meat’s extraordinary potential to produce more sustainable food.
“However, as the most common sources of meat are farm animals such as cattle, pigs, and poultry, most of the sustainable protein sector is focused on realistically replicating meat from these species.
“By cultivating beef, pork, chicken and seafood we can have the most impact in terms of reducing emissions from conventional animal agriculture.”
The Florence museum that houses Michelangelo’s statue of David has invited teachers and students from a Florida school to visit, after an uproar over an art lesson.
The school’s principal quit after a complaint about a sixth-grade art class that included an image of the statue.
A parent had complained the image was pornographic.
Cecilie Hollberg, director of Galleria dell’Accademia, has now issued the invitation to the class.
She said the principal should be “rewarded, not punished”.
“Talking about the Renaissance without showing the David, an undisputed icon of art and culture and of that historical period, would make no sense,” Ms Hollberg said.
The controversy began when the board of Tallahassee Classical School – a charter school in Florida’s state capital – pressured principal Hope Carrasquilla to resign after three parents complained about a lesson that included a photo of the 17ft nude marble statue.
The statue, one of the most famous in Western history, depicts the biblical David going to fight Goliath armed only with a sling and his faith in God.
[…]
The incident has left Florentines and experts on Renaissance art bewildered.
The David is considered a masterpiece of the Italian Renaissance and a symbol of humanist values. It has been displayed in the Galleria dell’Accademia since 1873.
Ms Hollberg said she was “astonished”, stating that to think that the David statue could be considered pornographic means not only failing to understand the Bible, but Western culture itself.
“I cannot believe that actually happened, at first I thought it was fake news, so improbable and absurd was it,” she said.
“A distinction must be made between nudity and pornography. There is nothing pornographic or aggressive about the David, he is a young boy, a shepherd, who even according to the Bible did not have ostentatious clothes but wanted to defend his people with what he had.”
[…]
According to Florentine art historian and dean of the University for Foreigners in Siena, Tomaso Montanari, such an attitude is “disconcerting”.
“First comes the dismay at the absence of educational freedom, as it should not be restricted or manipulated by families,” Mr Montanari said.
“On the other hand, from a cultural perspective, the Western world has a tendency to associate fundamentalism and censorship with other societies, believing it possesses the capability to spread democratic ideals worldwide.
“But this cultural backsliding clearly highlights the presence of fundamentalist views within the West as well.”
[…]
Back in Florence, Ms Hollberg remarked: “From majestic statues to charming fountains and paintings, Italy is overflowing with works of art, not just in its museums, but in all its cities, squares and streets, with some featuring naked figures.
“Does that make it pornography? Should entire cities be shut down because of the artistic depictions of the human form?”
