this rootless Python script rips Windows Recall's screenshots and SQLite database of OCRed text and allows you to search them.
Wow, it's pretty wild they didn't even attempt to encrypt or protect this data, even if it is local to your machine. What a treasure trove for malware to sift through.
110It IS encrypted. Not well, but it's encrypted.
21I thought that it was encrypted if your home directory was encrypted? The impression that I got was that it was just a SQLite database stored in the clear. The user must certainly be able to make queries of that database in order for it to work, so even if it's hosted by a non-user service, malware running locally will still be able to exfiltrate the data.
12Is it? I skimmed the GitHub source code and couldn't see anything involving encryption, but it's totally possible I missed something. Perhaps just accessing the database from python is enough to decrypt it.

Please go through the FAQ section of the git project. It's an eye-opener.
Q. Does this enable mass data breaches of website?
A. Yes. The next time you see a major data breach where customer data is clearly visible in the breach, you’re going to presume company who processes the data are at fault, right? But if people have used a Windows device with Recall to access the service/app/whatever, hackers can see everything and assemble data dumps without the company who runs the service even being aware. The data is already consistently structured in the Recall database for attackers. So prepare for AI powered super breaches. Currently credential marketplaces exist where you can buy stolen passwords — soon, you will be able to buy stolen customer data from insurance companies etc as the entire code to do this has been preinstalled and enabled on Windows by Microsoft.
94It's worst than that (as bad as this is)...
Today getting some data on a user is bad as smart hackers can put together the context ... However any guessing the hacker has to do may alert the user before the hacked data can successfully be exploited
Now, a hacker would know exactly where each password goes and worse, they'd could learn the entire workflow of internal systems to successfully imitate a trained user...
This means the hacker could use the stolen bank data and legitimately issue credit cards to anyone they want (for example)
It's no longer "we'll expose some data", now it's "we can use this data to infiltrate your systems and wreak havoc in whatever way we want"
13I doubt that. It’s preinstalled and enabled for personal users.
Even if it is enabled by default on pro/enterprise, there will probably be a group policy to disable it.

Sony BMG copy protection rootkit scandal
Morons:
Sony BMG initially denied that the rootkits were harmful. It then released an uninstaller for one of the programs that merely made the program's files invisible while also installing additional software that could not be easily removed, collected an email address from the user and introduced further security vulnerabilities.
85That’s wild. I’m surprised I never heard of this. Straight up malware.
25In a just society the Sony execs would have been jailed for CFAA violations.

Hilarious to me that it OCRs the text. The text is generated by the computer. It's almost like when Lt. Cmdr. Data wants to get information from the computer database, so he tells the computer to display it and just keeps increasing the speed --- there are way more efficient means of getting information from A to B than displaying it, imaging it, and running it though image processing!
I totally get that this is what makes sense, and it's independent of the method/library used for generating text, but still...the computer "knows" what it's displaying (except for images of text), and yet it has to screenshot and read it back.
70It happens the same on android for some reason
Like 5-8 years ago the google assistant app was able to select and copy text from any app when invoked, I think it was called “now on tap”. Then because they’re google and they’re contractually obligated to remove features after some time, they removed this from the google app and integrated it in the pixel app switcher (and who cares if 99% of android users aren’t using a pixel, they say). The new implementation sucks, as it does ocr instead of just accessing the raw text…
It only works fine with us English and not with other languages. But maybe it’s ok as it seems that google’s development style is us-centric
28Hey, yeah… why aren’t they just tapping the font rendering DLL?
…are they tapping the front rendering dll??
25My guess is that they looked at their screen reader API, saw that it wasnt 100% of the text on screen and said fuck it! Were using OCR!
2
Having worked on a product that actually did this, it's not as easy as it seems. There are many ways of drawing text on the screen.
GDI is the most common, which is part of the windows API. But some applications do their own rendering (including browsers).
Another difficulty, even if you could tap into every draw call, you would also need a way to determine what is visible on the screen and what is covered by something else.
24That's the thing, it doesn't really know what it's displaying. I can send a bunch of textboxes, but if they're hidden, or drawn off-screen, or underneath another element, then they're not actually displayed.
20Text from OCR is one kind of match. Recall also runs visual comparisons with the image tokens stored.
9To be fair, Data was designed to be like a human, and was made in the image of his creator. He has a number of design decisions that are essentially down to his creator wanting to create something like a human. Including that which you describe.
Data was never intended to work like a PC, it's very normal that he can't just wirelessly interface with stuff.

Wait so the malware won't even need a rootkit first? Damn this is worse than I thought...
66
67the screenshots and text are just sitting in the appdata folder, which requires no special permission to access
26Nice 😂 having extra pw manager n stuff in secret encrypted file only temporary handle decrypted PWs in RAM etc. But then, if you accidentally click on the eye, boom screenShot PW saved as pic of clear Text, nice. Also all personal eBanking stuff etc. And of Course, if you stream Netflix, tons of copyright protected material, lol.

Malware won't even need to wait for the user to access something sensitive, they can just go back through the user's Recall history and get the data for immediate exfiltration. No chance for anti-malware software to update and catch it before it does anything truly bad, it will just always be too late if given even a minute.

Imagine how easy is the life of law enforcement now.
Before if they seized a laptop encrypted with bit locker they could not do anything.
Now they just need to ask Microsoft the encryption password, which is automatically and silently saved in the Microsoft account (now mandatory) and they can have all the history of what the subject of the investigation did in the past years
64What? Bitlocker key tied to MS account and mandatory? What's the point of encryption if the key isn't secret any more?
34To protect against casual theft of a device causing the data to be in the thief's hands in addition to the actual device.
The average person unfortunately is not likely to properly backup their encryption keys so if they forget their password (or don't use one and rely on the default of just TPM), they'll complain about losing their data. Having the key backed up gives them a way to get their data back in non-theft situations.
30It’s secret to most, not all.

In a hilarious and infuriating side note, MS is obviously doing their absolute best to blame-shift here.
It’s code. It’s a project someone made to graphically illustrate and demonstrate, in the wild, why the entire concept of MS Recall is an absolutely awful, foundationally-flawed idea. It is not a “hacker tool”. The MS c-suite and board members are just pissed that stock go down as a result of their stupidity, and they’re looking for people to blame who aren’t themselves.
51MS is obviously doing their absolute best to blame-shift here
There is not a single word in that article that says anything about blame shifting. That title was written by wired.com
6Where is the blame shifting? The article says they made no comment and the only MS quotes are just random pr feature blurbs

How could the db be all plaintext unencrypted?!? I mean this is amateur hour at display here
46So . . . MS wants to force Recall on us.. Assures us that it's "secure." And it can't be bothered to even lightly encrypt the data? This is just plain incompetent.
Also, MS want to bundle CoPilot with Office 365, a subscription service. You will be paying for the privilege of spying on yourself.
33What an unexpected turn of events.
27Imagine if they zero day this.
26Lol "if". This thing is going to be a massive target.
24Someone has already demonstrated using an off-the-shelf infostealer to steal the Recall database from a test computer. It won't take any special skills or technology for this to be a problem.

That was quick.
6Is this thing even a thing? I see lots of discussion about it, but not real proof it was enabled across the board on all win 11 computers.
2it's on "Copilot+" PCs (i.e. ARM-based with an NPU)
3Yes. It's very very real and is just a typical Microsoft bullshit move.

Iirc chrome stores your local cookies/session in a place malware could also attack. Probably the same idea for other browsers.
I'm not sure I fully understand the issue here. If we're ok with that info being trivially retrievable by a bad actor, why isn't this ok?
Like I get you may not like it, and it's a target, but there are already lots of targets that have gotten a pass based on user permissions. Is it just the breadth of potential info? With the cookies you could potentially log into someone's bank account.
-7browser data is a potential liability, sure, but you have tools to manage it. you can delete pages or entire websites, you can use private windows, you can purge history older than 6 months or something like that, and at least a few browsers have a "forget" button that wipes out the last two hours of history. similar deals with cookies and other data, and we've collectively decided the benefit of having browser data is worth the risk.
not so here. Recall is a record of everything you've ever done on your PC. you can't selectively delete things like you can with browser history, the app and website exclusion is only as good as whatever Recall is using to detect apps and websites, and you can't redact sensitive info after the fact. people are generally okay with browser history and data because they know they have fine-grained controls to manage it, controls Recall doesn't have
9First, false equivalency.
Second, we’re not okay with cookies and session being in a place that could leak — it’s why we’re doing everything possible to stop that from happening (I mean GDPR alone is one effect of this).
Third, the fact that you can’t see a difference between cookies, which actually can be secured via proper encryption and signing, and a literally unencrypted database driven by OCRed screenshots (taken every couple of minutes) that requires an opt-out and is a very small slippery slope to that data making its way back to Microsoft’s own servers for their own greedy pursuits….then I’m not sure what to tell you.
Recall is wrong. And it’s indefensible. Period.
If you think it’s okay, then feel free to open everything up to Microsoft of who you are and what you do on your Copilot+ PC. I, for one, among many, will choose to secure my information as best as possible, including never using another Microsoft product again, if at all possible. And I’ve already done so for myself.
7GDPR has little to do with this. People use site cookies to remember sessions and not have to login again, etc. I'd guess most browser users use and want to use this functionality. If you're fully opting out to not even have persistent sessions, I'm guessing you're in the far minority of users here.
I'm not aware of any non-trivial readily available built-in encryption for cookies. There are easy to find libraries that exist to just pull out cookies (stored locally including session tokens).
To clear up a bit more misinformation from your response: this is an offline feature. The data doesn't go back to Microsoft. It works even if your computer is disconnected from the internet. If you consider their word to be a lie on this part, that's you're right to believe, but until proven, isn't a fact.
