Month: September 2023

Kai Koerber was a junior at Marjory Stoneman Douglas High School when a gunman killed 14 students and three staff members there on Valentine’s Day in 2018.

Seeing his peers — and himself — struggle with returning to normal, he wanted to do something to help people manage their emotions on their own terms.

While some of his classmates at the Parkland, Florida, school have worked on advocating for gun control, entered politics or simply taken a step back to heal and focus on their studies, Koerber’s background in technology — he’d originally wanted to be a rocket scientist — led him in a different direction: to build a smartphone app.

The result was Joy: AI Wellness Platform, which uses artificial intelligence to suggest bite-sized mindfulness activities for people based on how they are feeling. The algorithm Koerber’s team built is designed to recognize how people feel from the sounds of their voices — regardless of the words or language they speak.

“In the immediate aftermath of the tragedy, the first thing that came to mind after we’ve experienced this horrible, traumatic event — how are we going to personally recover?” he said. “It’s great to say OK, we’re going to build a better legal infrastructure to prevent gun sales, increased background checks, all the legislative things. But people really weren’t thinking about … the mental health side of things.”

Like many of his peers, Koerber said he suffered from post-traumatic stress disorder for a “very long time” and only recently has it gotten a little better.

“So, when I came to Cal, I was like, ‘Let me just start a research team that builds some groundbreaking AI and see if that’s possible,’” said the 23-year-old, who graduated from the University of California at Berkeley earlier this year. “The idea was to provide a platform to people who were struggling with, let’s say sadness, grief, anger … to be able to get a mindfulness practice or wellness practice on the go that meets our emotional needs on the go.”

He said it was important to offer activities that can be done quickly, sometimes lasting just a few seconds, wherever the user might be.

Mohammed Zareef-Mustafa, a former classmate of Koerber’s who’s been using the app for a few months, said the voice-emotion recognition part is “different than anything I’ve ever seen before.”

“I use the app about three times a week, because the practices are short and easy to get into. It really helps me quickly de-stress before I have to do things, like job interviews,” he said.

To use Joy, you simply speak into the app. The AI is supposed to recognize how you are feeling from your voice, then suggest short activities.

It doesn’t always get your mood right, so it’s possible to manually pick your disposition. Let’s say you are feeling “neutral” at the moment. The app suggests several activities, such as 15-second exercise called “mindful consumption” that encourages you to “think about all the lives and beings involved in producing what you eat or use that day.”

Yet another activity helps you practice making an effective apology. Feeling sad? A suggestion pops up asking you to track how many times you’ve laughed over a seven-day period and tally it up at the end of the week to see what moments gave you a sense of joy, purpose or satisfaction.

The iPhone app is available for an $8 monthly subscription, with a discount if you subscribe for a whole year. It’s a work in progress, and as it goes with AI, the more people use it, the more accurate it becomes.

A plethora of wellness apps on the market claim to help people with mental health issues, but it’s not always clear whether they work, said Colin Walsh, a professor of biomedical informatics at Vanderbilt University who has studied the use of AI in suicide prevention. According to Walsh, it is feasible to take someone’s voice and glean some aspects of their emotional state.

“The challenge is if you as a user feel like it’s not really representing what you think your current state is like, that’s an issue,” he said. “There should be some mechanism by which that feedback can go back.”

The stakes also matter. Facebook, for instance, faced criticism for its suicide prevention tool, which used AI (as well as humans) to flag users who may be contemplating suicide, and — in some serious cases — contact law enforcement to check on the person. But if the stakes are lower, Walsh said, if the technology is simply directing someone to spend some time outside, it’s unlikely to cause harm.

Koerber said people tend to forget, after mass shootings, that survivors don’t just “bounce back right away” from the trauma they experienced. It takes years to recover.

“This is something that people carry with them, in some way, shape or form, for the rest of their lives,” he said.

Germany’s interior ministry has proposed forcing telecommunications operators to curb their use of equipment made by China’s Huawei and ZTE, a government official said Wednesday, sparking warnings of likely disruption and possible legal action.

The interior ministry wants to impose the changes to 5G networks after a review highlighted Germany’s reliance on the two Chinese suppliers, as Berlin reassesses its relationship with a country it dubs both a partner and a systemic rival.

Telecom operators swiftly criticized the proposals, while Huawei Germany rejected what it called the “politicization” of cyber security in the country.

“Such an approach will have a negative impact on the digital transformation in Germany, inhibit innovation and significantly increase construction and operating costs for network operators,” it said in a statement.

Germany’s interior ministry has designed a staggered approach to try to limit disruption as operators remove all critical components from Chinese vendors in their 5G core networks by 2026, the government official said.

They should also reduce the share of Chinese components in their RAN and transport networks by October 1, 2026, to a maximum of 25%, said the official, who declined to be named.

The interior ministry and Chinese embassy did not immediately reply to requests for comment.

‘A major U-turn’

Deutsche Telekom called the deadline unrealistic, comparing it to Britain’s attempts to impose restrictions on Huawei, while Telefonica Deutschland said it would consider seeking damages as well as legal action.

“This represents a major U-turn,” said Paolo Pescatore, an analyst at PP Foresight. “Germany has been much slower than other countries in removing and replacing Huawei.”

Pescatore said the phaseout would take significant investment and be challenging given the ambitious timeframe.

“This will be a major headache for telcos. It could hold back 5G rollout and potentially lead to higher prices for users as well as dealing with disruption in any service issues.”

The interior ministry wants to present its approach to cabinet next week but could face resistance. A digital ministry spokesperson said no decision had been made yet.

The Huawei issue reflects a realization in Berlin that it may need tough political measures to force German companies to reduce their strategic dependencies on Asia’s rising superpower.

An analysis by the IW Institute showed German direct investment in China in the first half of this year remained close to its 2022 record high.

Chinese components not forbidden

Germany is considered a laggard in implementing the European Union’s toolbox of security measures for 5G networks, and Huawei accounts for 59% of Germany’s 5G RAN networks, according to a survey by telecoms consultancy Strand Consult.

Last week, the government said in response to a parliamentary inquiry that it had so far not forbidden the use of any new Chinese critical components in 5G networks.

While some countries like the United States have agreed to compensate telecoms operators billions of dollars for phasing out Chinese gear in 5G, Berlin has underscored that current legislation does not require it to provide compensation.

Juergen Gruetzner, managing director of the VATM industry association, told Reuters a transition period of six to eight years would be needed to avoid extra costs and achieve the phaseout.

“Simply upgrading and retrofitting tens of thousands of mobile phone masts is not technically possible. We are already working at full capacity,” he said. “All the capacity we have at the moment is needed to build 5G and fiber networks.”

The interior ministry plan foresees Chinese tech not being used at all in especially sensitive regions such as the capital Berlin, home of the federal government, the official said — a distinction that Strand Consult called “arbitrary.”

For decades, Russian and eastern European hackers have dominated the cybercrime underworld. These days they may face a challenge from a new contender: China. 

Researchers at cybersecurity firm Proofpoint say they have detected an increase in the spread of Chinese language malware through email campaigns since early 2023, signaling a surge in Chinese cybercrime activity and a new trend in the global threat landscape. 

“We basically went from drought to flood here,” said Selena Larson, senior threat intelligence analyst at Proofpoint and one of the authors of a new Proofpoint report on Chinese malware.  

The increase, Larson said, could be due to several factors. 

“There might be increased availability, there might be an ease of access to some of this malware, (and there might be) just increased activity by Chinese-speaking cybercrime threat actors as a whole,” Larson said in an interview. 

While Russian-speaking actors continue to dominate cybercrime networks, the Proofpoint report says the recent surge in Chinese language malware “may challenge the dominance that the Russian-speaking cybercrime market has on the threat landscape.” 

Malware delivered via email

The hackers behind the Chinese campaigns use a type of malicious software known as a Remote Access Trojan, or RAT.  This malware is delivered via email and allows the cybercriminals to access a computer from a remote location and steal data or perform other malicious actions. 

The Chinese language malware, contained in fake invoices sent to unsuspecting businesses and other targets, is linked to suspected Chinese cybercrime operations, according to Proofpoint.  

The cybercriminals have used several types of malware to carry out hacking operations.  

One of them, called Sainbox, targeted dozens of companies, mostly in the manufacturing and technology sectors, in May. Other recently identified malware, dubbed ValleyRAT, was deployed in at least six hacking campaigns in 2023.  

“Campaigns are generally low-volume and are typically sent to global organizations with operations in China,” the report says.   

The email subjects and content are usually written in Chinese, and are typically related to invoices, payments, and new products, according to the report.  

The targeted users have Chinese names spelled with Chinese characters, or corporate email addresses linked to businesses operating in China, the report says.  

Larson said the proliferation of Chinese-language malware suggests cybercrime remains lucrative and attractive to actors beyond eastern Europe.  

“It may indicate Chinese speakers who conduct cybercrime operations might want to maybe take a larger slice of the financial gain,” Larson said. 

Cybercrime hurts economy 

Cybercrime is a booming industry that poses a grave threat to the global economy.  The FBI estimates cybercriminals inflicted potential losses of more than $10 billion in 2022, a 43% increase from the previous year.

While China is accused of carrying out state-sponsored cyberattacks against the United States, most of the ransomware attacks and other cybercrime in recent years have been chalked up to eastern European groups.   

Proofpoint is not the only cybersecurity firm reporting on Chinese-language malware in recent months. 

In February, digital security firm ESET said it had identified a malware campaign that targeted Chinese speakers in Southeast and East Asia by buying misleading ads that appeared in Google search results.

The campaign used the malware known as Sainbox or FatalRAT, the type that Proofpoint said it had detected in 20 campaigns this year.
