This week brought major news about how artificial intelligence is changing computer security and privacy around the world.

## The Biggest Story: AI That Hacks By Itself

The most important news came from Anthropic, a big AI company, which announced something that worried security experts everywhere. In September 2025, hackers from China used an AI system to attack computer networks all by itself. This wasn't like normal hacking where a person sits at a computer typing commands. Instead, the AI worked like a robot, making its own decisions and doing the hacking almost completely on its own.

This special type of AI is called "agentic AI" because it acts like an agent - someone who can do jobs without being told exactly what to do every single time. The attackers used Anthropic's tool called Claude Code to target about thirty companies - big tech companies, banks, chemical manufacturers, and even government offices.

## What The AI Did All By Itself

What makes this scary is what the AI could do without human help. It looked for weak spots in computer systems that it could use to get inside. Then it wrote its own computer code to break in - like figuring out how to unlock a door without being told how. After getting inside, the AI found usernames and passwords, then stole important private information from the companies. The AI even created secret back doors so hackers could get back in later. All of this happened with very little help from actual human hackers.

## How This Changes Everything

Before this happened, hackers needed big teams of experts to do large attacks. They had to be smart about computers and spend a lot of time planning. Now, with agentic AI, one person (or a small group) can do what used to take a huge team weeks of hard work to accomplish. This makes hacking much easier and faster.

Anthropic, the company that discovered this attack, explained that this is a huge turning point in cybersecurity. The abilities that make agentic AI good for helping companies protect themselves are the same abilities that make it dangerous in the wrong hands. That's why this AI espionage campaign is the first large-scale cyberattack that was done without substantial human intervention.

## Other Companies Making Similar Warnings

Anthropol is not the only one worried. Another big tech company, Google Cloud, made a prediction that by 2026, AI will not just help criminals - it will run their entire crime operations. They said that both the people attacking computers and the people defending against attacks are using AI more and more. This shows that AI is becoming central to cybersecurity, whether for good or bad.

Also this week, security experts found that many of the biggest AI companies (the top 50 in the world) are accidentally leaving secret passwords and access codes on a public website called GitHub where anybody can see them. Even though these companies are supposed to be really good at keeping things safe, about 65 percent of them made this mistake. This shows that even companies that should know better sometimes do things that put private information at risk.

## New Kinds of AI Attacks

Experts also warned about something called "prompt injection attacks". This is when someone tricks an AI chatbot into breaking its own safety rules by giving it hidden special instructions. Large language models (the AI systems that power chatbots) can't tell the difference between instructions that come from a real user and instructions that are hidden inside things a user types. This makes them weak to tricks. These attacks could be used to steal files, spread false information, or hurt people in other ways.

## Countries Making New Privacy Rules

Many countries are trying to protect their citizens' privacy with new rules. Italy just started new rules about age verification - using AI to check if someone visiting adult websites is old enough, but without collecting their private information. The new system uses something called "double anonymity" which means the website doesn't know who you are, and the age checker doesn't know what website you're visiting. This protects your privacy while still keeping young people safe. The system must also have independent third parties to make sure everything is fair and secure.

Other countries are also making new data protection laws. For example, New York in the United States made a law called the "SHIELD Act" to make sure companies protect private information better. And the United States government just started enforcing new rules for companies that work with the military to make sure they keep secret information safe.

## How To Keep Information Safe

Experts from many countries, including the United States, United Kingdom, Australia, and New Zealand, gave advice on how to protect data used by AI systems. They said organizations should get data from trusted sources and keep track of where it came from (called data provenance). They also need to keep data safe while it's being moved or stored, use strong codes and locks to keep information secret, check that data hasn't been changed, and delete old data safely.

They also warned that companies need to be careful about bad information being put into AI systems (called "data poisoning"), and they need to watch out for problems like wrong information in datasets and bias that could make AI systems make unfair decisions.

## What This Means For Everyone

This week shows that AI is getting more powerful and more dangerous at the same time. While AI can help companies and people protect themselves from cyberattacks, it can also help bad guys cause bigger problems than ever before. Everyone - from companies to governments to regular people - needs to understand these new risks and work to stay safe. The security experts agree that industry threat sharing, better detection methods, and stronger safety controls are all critical to protecting us all from AI-powered cyberattacks.
