Washington — With major military setbacks in recent years, supporters of the Islamic State terror group are increasingly relying on artificial intelligence (AI) to generate online propaganda, experts said.

A new form of propaganda developed by IS supporters is broadcasting news bulletins with AI-generated anchors in multiple languages.

The Islamic State Khorasan (ISKP) group, an IS affiliate active in Afghanistan and Pakistan, produced in a video an AI-generated anchorman to appear reading news following an IS-claimed attack in Bamiyan province in Afghanistan on May 17 that killed four people, including three Spanish tourists.

The digital image posing as an anchor spoke the Pashto language and had features resembling local residents in Bamiyan, according to The Khorasan Diary, a website dedicated to news and analysis on the region.

Another AI-generated propaganda video by Islamic State appeared on Tuesday with a different digital male news anchor announcing IS’s responsibility for a car bombing in Kandahar, Afghanistan.

“These extremists are very effective in spreading deepfake propaganda,” said Roland Abi Najem, a cybersecurity expert based in Kuwait.

He told VOA that a group like IS was already effective in producing videos with Hollywood-level quality, and the use of AI has made such production more accessible for them.

“AI now has easy tools to use to create fake content whether it’s text, photo, audio or video,” Abi Najem said, adding that with AI, “you only need data, algorithms and computing power, so anyone can create AI-generated content from their houses or garages.”

IS formally began using the practice of AI-generated news bulletins four days after an attack at a Moscow music hall on March 22 killed some 145 people. The attack was claimed by IS.

In that video, IS used a “fake” AI-generated news anchor talking about the Moscow attack, experts told The Washington Post last week.

Mona Thakkar, a research fellow at the International Center for the Study of Violent Extremism, said pro-IS supporters have been using character-generation techniques and text-to-speech AI tools to produce translated news bulletins of IS’s Amaq news agency.

“These efforts have garnered positive responses from other users, reflecting that, through future collaborative efforts, many supporters could produce high quality and sophisticated AI-powered propaganda videos for IS of longer durations with better graphics and more innovation techniques,” she told VOA.

Thakkar said she recently came across some pro-IS Arabic-speaking supporters on Telegram who were recommending to other supporters “that beginners use AI image generator bots on Telegram to maintain the high quality of images as the bots are very easy and quick to produce such images.”

AI-generated content for recruitment

While IS’s ability to project power largely decreased due to its territorial defeat in Syria and Iraq, experts say supporters of the terror group believe artificial intelligence offers an alternative to promote their extremist ideology.

“Their content has mainly focused on showing that they’re still powerful,” said Abi Najem. “With AI-generated content now, they can choose certain celebrities that have influence, especially on teenagers, by creating deepfake videos.”

“So first they manipulate these people by creating believable content, then they begin recruiting them,” he said.

In a recent article published on the Global Network on Extremism and Technology, researcher Daniel Siegel said generative AI technology has had a profound impact on how extremist organizations engage in influence operations online, including the use of AI-generated Muslim religious songs, known as nasheeds, for recruitment purposes.

“The strategic deployment of extremist audio deepfake nasheeds, featuring animated characters and internet personalities, marks a sophisticated evolution in the tactics used by extremists to broaden the reach of their content,” he wrote.

Siegel said that other radical groups like al-Qaida and Hamas have also begun using AI to generate content for their supporters.

Cybersecurity expert Abi Najem said he believes the cheap technology will increase the availability of AI-generated content by extremist groups on the internet.

“While currently there are no stringent regulations on the use of AI, it will be very challenging for governments to stop extremist groups from exploiting these platforms for their own gain,” he said.

SYDNEY — A device that absorbs water from air to produce drinkable water was officially launched in Australia Wednesday.

Researchers say the so-called Hydro Harvester, capable of producing up to 1,000 liters of drinkable water a day, could be “lifesaving during drought or emergencies.”

The device absorbs water from the atmosphere. Solar energy or heat that is harnessed from, for example, industrial processes are used to generate hot, humid air. That is then allowed to cool, producing water for drinking or irrigation.

The Australian team said that unlike other commercially available atmospheric water generators, their invention works by heating air instead of cooling it.

Laureate Professor Behdad Moghtaderi, a chemical engineer and director of the University of Newcastle’s Centre for Innovative Energy Technologies, told VOA how the technology operates.  

“Hydro Harvester uses an absorbing material to absorb and dissolve moisture from air. So essentially, we use renewable energy, let’s say, for instance, solar energy or waste heat. We basically produce super saturated, hot, humid air out of the system,” Moghtaderi said. “When you condense water contained in that air you would have the drinking water at your disposal.”

The researchers say the device can produce enough drinking water each day to sustain a small rural town of up to 400 people. It could also help farmers keep livestock alive during droughts.

Moghtaderi says the technology could be used in parts of the world where water is scarce.

Researchers were motivated by the fact that Australia is an arid and dry country.

“More than 2 billion people around the world, they are in a similar situation where they do not have access to, sort of, high-quality water and they deal with water scarcity,” Moghtaderi said

Trials of the technology will be conducted in several remote Australian communities this year.

The World Economic Forum, an international research organization, says “water scarcity continues to be a pervasive global challenge.”

It believes that atmospheric water generation technology is a “promising emergency solution that can immediately generate drinkable water using moisture in the air.”

However, it cautions that generally the technology is not cheap, and estimates that one mid-sized commercial unit can cost between $30,000 and $50,000.

SYDNEY — Researchers in Australia and the United States say that a new artificial intelligence tool has allowed them to classify brain tumors more quickly and accurately.  

The current method for identifying different kinds of brain tumors, while accurate, can take several weeks to produce results.  The method, called DNA methylation-based profiling, is not available at many hospitals around the world.

To address these challenges, a research team from the Australian National University, in collaboration with the National Cancer Institute in the United States, has developed a way to predict DNA methylation, which acts like a switch to control gene activity.  

This allows them to classify brain tumors into 10 major categories using a deep learning model.

This is a branch of artificial intelligence that teaches computers to process data in a way that is inspired by a human brain.

The joint U.S.-Australian system is called DEPLOY and uses microscopic pictures of a patient’s tissue called histopathology images.

The researchers see the DEPLOY technology as complementary to an initial diagnosis by a pathologist or physician.

Danh-Tai Hoang, a research fellow at the Australian National University, told VOA that AI will enhance current diagnostic methods that can often be slow.

“The technique is very time consuming,” Hoang said. “It is often around two to three weeks to obtain a result from the test, whereas patients with high-grade brain tumors often require treatment as soon as possible because time is the goal for brain tumor(s), so they need to get treatment as soon as possible.”

The research team said its AI model was validated on large datasets of approximately 4,000 patients from across the United States and Europe and an accuracy rate of 95 percent.

Their study has been published in the journal Nature Medicine.
