14 DAY TRIAL // An ex-NSA hacker has created a security app for Apple's macOS operating system that promises to protect your Mac from so-called "evil maid" attacks.
The app is called Do Not Disturb (DND), and it's both free and open-source. It is one of those apps that do one thing and do it well, continually monitoring in the background for "lid open" events in case someone with physical access to your Mac attempts to use it when you're not around. The scenarios on that are infinite and beyond, so it's a must-have app!
"Do Not Disturb (DND) continually monitors your system for events that may indicate a precursor of "evil maid" attack. Specifically it watches for 'lid open' events," explains the developer. "If you've shut your laptop (and thus triggered sleep mode), the majority of physical access attacks may require the lid to be opened in order for the attack to succeed."
Among the attacks that the Do Not Disturb (DND) app can detect, we can mention inserting a maliciously crafted device into the USB or Thunderbolt port of your Mac, logging in locally with your credentials obtained with a hidden camera, as well as logging in locally as root (system administrator) by exploiting known flaws like “I Am Root”.
Companion iOS app inform you in real-time about "evil maid" attacks
If you think the Do Not Disturb (DND) app is cool, you should also know that it comes with a companion iOS app for your iPhone or iPad so you'll get real-time notification of such "evil maid" attacks on your Mac. However, while Do Not Disturb (DND) for Mac is free, the Do Not Disturb Companion iOS app has a $0.99 monthly or $9.99 annually subscription.
We think it's a small price to pay if you have important documents on your Mac and you don't want anyone to see them. the Do Not Disturb Companion iOS app is free to download and use for 7 days, with unlimited remote alerts and actions, so you won't aren't forced to buy a subscription immediately if you don't find it useful.
