Use this hack to make AirTags easier to open

When your AirTags' batteries are low (or, let's face it, dead), you can replace them yourself—assuming you bought the proper batteries. But they're not the easiest to open up: You have to press down on the silver back of your AirTag and rotate it counterclockwise until the cover comes loose. If you're having trouble getting it to work, you're not alone. But there's a simple hack to make it a bit easier. I stumbled upon this via MacGeekGab on YouTube. The idea is, take a small amount of tape on t

Use an AirTag as an NFC tag

Your AirTag isn't just a tracker; it's also an NFC tag. This technology is what makes tap-to-pay work: You wave your iPhone over the tag, which triggers some pre-planned action. In this case, you can set up your AirTag to run any automation you want in Apple Shortcuts. For example, this Redditor uses it to remind themselves to take their medication; if they don't scan their AirTag, which they've stuck underneath the lid of their medication bottle, they'll receive a reminder.

To find the serial number of an AirTag, use the Find My app, tap it with an NFC-capable smartphone, or look under the battery.

Chaos ransomware msaRAT hides its C2 channel inside a legitimate browser process

The Chaos ransomware group uses new malware "msaRAT" that hijacks browsers. The malware doesn't communicate directly with C2 but connects through the browser. It enables arbitrary command execution while hiding the attacker's IP from victims via WebRTC over TURN.

Circadian windows are easier to read

When is the best time in the morning to have some caffeine? If you never thought about it much, you probably drink your coffee as soon as you can. On the other hand, if you’re always looking for ways to optimize your life (maybe we’d even say hack it), you may have heard the advice to wait until mid-morning. Good news: you can ditch this supposed hack. There’s no need to delay your morning caffeine. Drink it when you want it.

What this update means for those wearing Ultrahuman ring

Overall, I’ve found the experience of using the ring a lot more pleasant alongside the new app redesign. Ultrahuman says that data processing now happens on-device, so you don’t need an internet connection to get your metrics and recommendations. I’m still working my way through the app’s features as I test the Ring Pro, but I’m looking forward to the improved heart rate accuracy and the ability to use data from Garmin and other devices for workouts. There’s even a feature to “train your ring” b
