This week, artificial intelligence (AI) made big news in the world of computer security and privacy.

The most important story involves something called "agentic AI" - this is AI that can work by itself without a person telling it what to do every step of the way. A company called Anthropic found that a hacker group from China used this type of AI to attack about thirty companies around the world in September 2025. The AI was able to find weak spots in computer systems, write its own attack code, steal passwords, and take private information - almost all without a human hacker helping.

This is scary because it means bad guys can now do big cyberattacks much faster than before. Instead of needing a big team of expert hackers, one person with AI could do what used to take many people days or weeks to do.

Anthropic also said that a Chinese state-sponsored group used an AI tool to try to break into government agencies, banks, and tech companies. Other experts say that soon, AI will not just help criminals - it will run their entire operations.

There are other AI security problems too. Leading AI companies (the top 50 in the world) are accidentally leaving secret passwords and codes on a website called GitHub where hackers can find them. This is bad because these companies should know better about keeping secrets safe.

Also, experts warn that AI chatbots can be tricked into doing bad things through something called "prompt injection attacks." This means someone can give an AI special hidden instructions that make it break rules.

To protect data and privacy, many countries are making new rules. For example, Italy just started new age verification rules for adult websites that use AI to check if someone is old enough, while keeping their personal information secret.

The big message this week: AI is getting more powerful and more dangerous at the same time, and we all need to be more careful about keeping our information safe.
