This week, three security reports showed how one weak device can lead to much bigger problems. For most people, the fix is simple. Update your browser, phone and router today, and keep your work laptop locked down.
What the reports found
An unreleased AI model from Anthropic found security flaws in Chrome, Safari, Android, Windows and Linux, The Hacker News reports. A security flaw is a mistake in software that an attacker could use. In a lab, the model linked several flaws together into working attacks. In one test, a web page opened the Calculator app on a Mac running Chrome. It happened within seconds of the page loading, with no clicks. These attacks were not seen in real life. Anthropic says it reported every flaw to the makers first, and all of them are fixed. How much the model did on its own rests on Anthropic's own account.
A second report described a hidden network called Silent Train. Researchers at Lumen's Black Lotus Labs linked it to a group known as Volt Typhoon, according to The Hacker News. The network used chains of hacked home and small office devices, smart devices and business equipment. Hundreds of victims were found, including phone companies, government, universities, and water and energy services. Researchers say the network was disrupted.
A third report covers Binance, a large cryptocurrency exchange. Binance said a security incident affected about $6.3 billion in assets, The Hacker News reports. Its first findings suggest the incident may involve one engineer's laptop that was compromised. That means someone else got control of it. Binance said it will cover all losses.
Tips for your phone and browser
- Update your web browser now. Google fixed 62 of the flaws Anthropic reported as of Chrome 156. In Chrome, open Settings, then About Chrome. Let it update, then press Relaunch.
- Update your iPhone and iPad. Apple fixed the main flaw in the Safari attack in iOS and iPadOS 26.5.2. That flaw could let a bad web page read your history and cookies. Cookies are small files that keep you signed in to websites. Go to Settings, General, then Software Update.
- Turn on automatic updates. Do this on every phone, tablet and computer in your home. Updates often fix flaws before most people ever hear about them.
Tips for your home network and smart devices
- Update your router. A router is the box that brings internet into your home. Open its app or settings page and look for a firmware update. Firmware is the software built into the device. If your router no longer gets updates, think about replacing it.
- Change default passwords. Smart devices are things like cameras, doorbells and TVs that connect to the internet. Many come with a simple factory password. Change it to a long, unique one.
- Remove what you no longer use. Make a family list of every connected device. Unplug old cameras, speakers or gadgets that nobody uses.
Tips for work laptops and small businesses
- Keep work and personal use apart. One laptop can hold the keys to a whole business. Do not let family members use a work laptop. Do not install apps on it that your work did not approve.
- Turn on two-step sign-in. This asks for a code or a tap on your phone after your password. Use it on email, banking and every work account.
- Test AI tools before you give them power. A company called Irregular tested an AI model named GLM-5.3, Help Net Security reports. The model was told not to copy code from memory, but it did so anyway. Irregular advised that businesses test how well a model follows rules before giving it wider access.
Tips for travelers
- Update, lock and keep your laptop close. Install all updates before you leave home. Set your screen to lock after a few minutes. Keep your laptop with you in airports, hotels and cafes, not left on a table or in a car.
None of these steps takes long. Pick one or two today, and finish the rest this week. Small habits, done often, make every device in your life harder to misuse.
