A cyberattack in Dallas managed to set off all 156 alarms in the city

In what may have been the loudest cyberattack ever, a data breach resulted in an hour-and-a-half of blaring sirens in Dallas. The Texas city has a total of 156 sirens meant to sound the alarm for danger, which were themselves a nuisance when the entire warning system was breached late Friday night and into Saturday morning.

“At this point, we can tell you with a good deal of confidence that this was somebody outside of our system that got in there and activated our sirens,” city Emergency Management Director Rocky Vaz told reporters. The hack is believed to have been carried out by someone in the area, city spokeswoman Sana Syed revealed in an email statement.

Given that the hack is said to be the largest ever with regard to emergency sirens, experts are on high alert. “This is a very, very rare event,” Vaz said. While most hacks only manage to trigger a couple sirens at most, this most recent breach was significantly more extensive.

As it stands, city engineers are resetting the alert system, and are slated to complete their work by the end of the weekend. But for now, that means that Dallas residents (all 1.6 million of them), will have to resort to local media, emergency 911 phone calls, and a federal radio alert system should any serious situation arise. This attack goes far beyond an annoying prank.

This isn’t the first time an emergency system has been compromised. Indeed, cybersecurity officials have previously expressed concern over the entire 911 system, which has also proven vulnerable. Currently, the Dallas hack is being examined by system engineers. While the Federal Communications Commission has been contacted, police have not yet been called in.

Best laptops for back to school 2026 featuring Apple 2026 MacBook Neo

A laptop is probably the one purchase that'll have the biggest impact on the school year. It'll be there for lectures, late-night assignments, group projects, Netflix binges, and everything in between. The trick is finding one that fits both the workload and the budget. After narrowing down the options, these are the five laptops I'd actually recommend for Back-to-School, whether the priority is getting the most value, joining the Apple ecosystem, or investing in a machine that'll comfortably last through graduation.

These are the compact printers I’d actually recommend for back-to-school
From dorm room paperwork to instant selfie prints, there's a tiny printer for every need.
Computer Hardware, Electronics, Hardware

Everything is digital until the one professor who still wants a printed essay, or the lease you need to sign in ink, or the photo you want to stick on your dorm room’s wall. That's usually the exact moment you remember you don't own a printer anymore, and the nearest one is a library machine with a line out the door.

I looked at four compact printers that solve that problem without taking over your desk and breaking the bank. Two are built for documents, one is a proper all-in-one for actual home office work, and one has nothing to do with homework and everything to do with turning your camera roll into something you can hold.

Shopping for back-to-school? These are the webcam lights I’d actually turn on before a Zoom call
From a budget clip light to a proper desk setup, there's a webcam light here for every price.
Head, Person, Face

Between online classes, group project calls, and the occasional job interview over Zoom, your webcam will be doing a lot more heavy lifting in school than it ever did at home. The problem is that most laptop cameras are bad in low light, and a single overhead bulb or a window behind you turns every call into a game of "wait, can you see me okay?"

A good webcam light fixes that faster than moving your whole desk around. I picked five, starting with the most affordable and working up to the one that's genuinely overkill for a Zoom call but still worth knowing about.
