Do Not Disturb alerts you to potential ‘Evil Maid’ attacks by notifying your iPhone of attempts to gain physical access your MacBook, perhaps without your consent or knowledge.

The companion Do Not Disturb macOS app (DND macOS) is offered as a free download to continually monitor your laptop for lid open events, as a precursor to these “Evil Maid” attacks.

With this iOS app (DND iOS), you will receive alerts on your iPhone and can respond to them in real time. The following remote response actions are supported:

* Use the MacBook camera to take a picture and return the image to your phone
* Initiate a hard shutdown to trigger enabled FileVault disk encryption
* Dismiss alerts on the iPhone and MacBook
… all with the touch of a button!

The DND iOS is free to download and includes a 7 day free trial with unlimited remote alerts and actions. Continued service requires an in-app subscription purchase (details below).

Technical Comments

DND performs its function very well.
However, I would have liked to see more technical documentation on the type of encryption used to facilitate the transfer of data between the iOS App and the MacOS Client. In addition, Having the security related portions of the projects code be open source on github would have built better credibility for the app.
Also having a feature to remove photos from the iOS app after being taken from the Mac would be great.

Developer Response ,

Thank you for your feedback and your support of DND.

We agree that we can/should provide more technical documentation on our data transfers and we will work to do so in the near future. We continue to consider open sourcing certain parts of our code base for increased transparency as well.

We've also noted your request for a (more apparent) way to remove photos from the app once taken. In the meantime, you can select the information button (i) on the device view. Then select either "Clear Events" if you prefer a clean slate or select "Events" from the table to interact with and delete individual events (including photos).

Excellent security tool, a must have!

DND is a must for anyone who owns both an iPhone and a Mac laptop computer — and who cares about the easily exploitable physical access security vulnerabilities of one’s Mac laptop. DND does exactly what it says it’ll do.

Sanctioned by Patrick, his work is well-served and honored as a part of this application. The nominal fee for annual service is well worth it to me to help incentivize further innovation by Patrick and Digita Security who have worked hard to produce a top-tier app, to maintain it, and to release future versions. That’s basic capitalism, folks. If you don’t like it, with all due respect, please do a quick search to see what “amazing” apps Cuba has put out lately. (None.)

Whaaaa 👶🏻

I enjoyed reading the one star reviews from cheapskates who can’t read. $10 a year is nothing for advanced security. Would not be surprised if apple eventually bakes this in to Mac/iOS.
