Q. Is this really as harmful as you think?

A. Go to your parents house, your grandparents house etc and look at their Windows PC, look at the installed software in the past year, and try to use the device. Run some antivirus scans. There’s no way this implementation doesn’t end in tears — there’s a reason there’s a trillion dollar security industry, and that most problems revolve around malware and endpoints.

    Q. The data is processed entirely locally on your laptop, right?

A. Yes! They made some smart decisions here, there’s a whole subsystem of Azure AI etc code that process on the edge.

Q. Cool, so hackers and malware can’t access it, right?

A. No, they can.

Q. But it’s encrypted.

A. When you’re logged into a PC and run software, things are decrypted for you. Encryption at rest only helps if somebody comes to your house and physically steals your laptop — that isn’t what criminal hackers do.

For example, InfoStealer trojans, which automatically steal usernames and passwords, are a major problem for well over a decade — now these can just be easily modified to support Recall.

Q. But the BBC said data cannot be accessed remotely by hackers.

A. They were quoting Microsoft, but this is wrong. Data can be accessed remotely.

Q. Microsoft say only that user can access the data.

A. This isn’t true, I can demonstrate another user account on the same device accessing the database.

Q. So how does it work?

A. Every few seconds, screenshots are taken. These are automatically OCR’d by Azure AI, running on your device, and written into an SQLite database in the user’s folder.

This database file has a record of everything you’ve ever viewed on your PC in plain text. OCR is a process of looking an image, and extracting the letters.

Q. What does the database look like?

Q. How do you obtain the database files?

A. They’re just files in AppData, in the new CoreAIPlatform folder.

Q. But it’s highly encrypted and nobody can access them, right?!

A. Here’s a few second video of two Microsoft engineers accessing the folder: https://cyberplace.social/system/media_attachments/files/112/535/509/719/447/038/original/7352074f678f6dec.mp4

Q. …But, normal users don’t run as admins!

A. According to Microsoft’s own website, in their Recall rollout page, they do: https://miro.medium.com/v2/resize:fit:1100/format:webp/0*WGE1jcRzhe6WAGQS

In fact, you don’t even need to be an admin to read the database — more on that in a later blog.

Q. But a UAC prompt appeared in that video, that’s a security boundary.

A. According to Microsoft’s own website (and MSRC), UAC is not a security boundary: https://miro.medium.com/v2/resize:fit:1100/format:webp/1*TTjYNH15IoP_d8JhhG3cEA.png

Q. So… where is the security here?

A. They have tried to do a bunch of things but none of it actually works properly in the real world due to gaps you can drive a plane through.

Q. Does it automatically not screenshot and OCR things like financial information?

A. No: https://miro.medium.com/v2/resize:fit:1100/format:webp/1*OZMjujpALL3IfAQYT64x7Q.png

    Do I have to continue or do you think you could actually read the article for the rest? It’s clearly a bigger deal than “linux users mad because windows better” and your poor excuse for a troll just makes it look like you’re too stupid to read the article laid out in front of you. Well, now you have no excuse so get good.
