The Download: AI-enhanced cybercrime, and secure AI assistants

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

AI is already making online crimes easier. It could get much worse.

Just as software engineers are using artificial intelligence to help write code and check for bugs, hackers are using these tools to reduce the time and effort required to orchestrate an attack, lowering the barriers for less experienced attackers to try something out.

Some in Silicon Valley warn that AI is on the brink of being able to carry out fully automated attacks. But most security researchers instead argue that we should be paying closer attention to the much more immediate risks posed by AI, which is already speeding up and increasing the volume of scams.

Criminals are increasingly exploiting the latest deepfake technologies to impersonate people and swindle victims out of vast sums of money. And we need to be ready for what comes next. Read the full story.

Is a secure AI assistant possible?

AI agents are a risky business. Even when stuck inside the chatbox window, LLMs will make mistakes and behave badly. Once they have tools that they can use to interact with the outside world, such as web browsers and email addresses, the consequences of those mistakes become far more serious.

Viral AI agent project OpenClaw, which has made headlines across the world in recent weeks, harnesses existing LLMs to let users create their own bespoke assistants. For some users, this means handing over reams of personal data, from years of emails to the contents of their hard drive. That has security experts thoroughly freaked out.

In response to these concerns, its creator warned that nontechnical people should not use the software. But there’s a clear appetite for what OpenClaw is offering, and any AI companies hoping to get in on the personal assistant business will need to figure out how to build a system that will keep users’ data safe and secure. To do so, they’ll need to borrow approaches from the cutting edge of agent security research. Read the full story.

What’s next for Chinese open-source AI

The past year has marked a turning point for Chinese AI. Since DeepSeek released its R1 reasoning model in January 2025, Chinese companies have repeatedly delivered AI models that match the performance of leading Western models at a fraction of the cost.

These models differ in a crucial way from most US models like ChatGPT or Claude, which you pay to access and can’t inspect. The Chinese companies publish their models’ weights—numerical values that get set when a model is trained—so anyone can download, run, study, and modify them. 

If open-source AI models keep getting better, they will not just offer the cheapest options for people who want access to frontier AI capabilities; they will change where innovation happens and who sets the standards. Here’s what may come next.

Why EVs are gaining ground in Africa

EVs are getting cheaper and more common all over the world. But the technology still faces major challenges in some markets, including many countries in Africa.

Some regions across the continent still have limited grid and charging infrastructure, and those that do have widespread electricity access sometimes face reliability issues—a problem for EV owners, who require a stable electricity source to charge up and get around. But there are some signs of progress. Read the full story.

Quote of the day

“I still try to believe that the good that I’m doing is greater than the horrors that are a part of this. But there’s a limit to what we can put up with. And I’ve hit my limit.”

—An anonymous Microsoft worker explains why they’re growing increasingly frustrated with their employer’s links to ICE, the Verge reports. 

One more thing

Motor neuron diseases took their voices. AI is bringing them back.

Jules Rodriguez lost his voice in October 2024. His speech had been deteriorating since a diagnosis of amyotrophic lateral sclerosis (ALS) in 2020, but a tracheostomy to help him breathe dealt the final blow. 

Rodriguez and his wife, Maria Fernandez, who live in Miami, thought they would never hear his voice again. Then they re-created it using AI. After feeding old recordings of Rodriguez’s voice into a tool trained on voices from film, television, radio, and podcasts, the couple were able to generate a voice clone—a way for Jules to communicate in his “old voice.”

Rodriguez is one of over a thousand people with speech difficulties who have cloned their voices using free software from ElevenLabs. The AI voice clones aren’t perfect. But they represent a vast improvement on previous communication technologies and are already improving the lives of people with motor neuron diseases. Read the full story.
