The Do Not Disturb (DND) detects devices plugged into the Mac via USB or Thunderbolt ports, detects if a background application is secretly using the camera, etc., and fixes the “I Am Root” vulnerability.
Former NSA expert released a “Do Not Disturb” app to detect Evil Maid Attacks for Mac users
Former US National Security Agency (NSA) hacker recently launched a security application called “Do Not Disturb (DND)” for Apple’s macOS system, claiming to help your Mac defend against “Evil Maid Attack”. This security app is also a free and open source. This application only does one thing: Listening to the background of the Mac to see if there is a “lid open” event, to avoid someone physically obtaining your confidential information when you are not there.
The developer explained: “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.
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. Such attacks could include:
- Logging in locally as root, by exploiting a bug such as ‘#iamroot’
- Locally logging in via credentials captured by a hidden camera
- Inserting a malicious device into a USB or Thunderbolt port.“
