I've just been playing around with https://browserleaks.com/fonts . It seems no web browser provides adequate protection for this method of fingerprinting -- in both brave and librewolf the tool detects rather unique fonts that I have installed on my system, such as "IBM Plex" and "UD Digi Kyokasho" -- almost certainly a unique fingerprint. Tor browser does slightly better as it does not divulge these "weird" fonts. However, it still reveals that the google Noto fonts are installed, which is by far not universal -- on a different machine, where no Noto fonts are installed, the tool does not report them.

For extra context: I've tested under Linux with native tor browser and flatpak'd Brave and Librewolf.

What can we do to protect ourselves from this method of fingerprinting? And why are all of these privacy-focused browsers vulnerable to it? Is work being done to mitigate this?

What is the general consensus on trusting data removal services with the data you provide them?

I’ve spent 5 years telling myself I’ll go through the long lists of data aggregators and one by one manually send removal requests. But it’s such a massive undertaking. I’d like to finally get it done through one of these services, but my gut tells me it feels wrong.

Has anybody used them and how do you feel about it? Is DeleteMe a good choice?

I want to keep a timeline of the places I go like Google Maps can, and export it to mac for my diary*. The maps app doesn't have to be great, it just needs to keep a timeline in the background, I would still use Apple Maps as my main navigation app.

*(ideally I can automatically export it somehow, perhaps with the Shortcuts and Scriptable app but just tell me any apps with a timeline and export feature)

Leaked Docs Show What Phones Cellebrite Can (and Can’t) Unlock

The leaked April 2024 documents, obtained and verified by 404 Media, show Cellebrite could not unlock a large chunk of modern iPhones.

Cellebrite, the well-known mobile forensics company, was unable to unlock a sizable chunk of modern iPhones available on the market as of April 2024, according to leaked documents verified by 404 Media.

The documents, which also show what various Android handsets and operating system versions Cellebrite can access, provide granular insight into the very recent state of mobile forensic technology. Mobile forensics companies typically do not release details on what specific models their tools can or cannot penetrate, instead using vague terms in marketing materials. The documents obtained by 404 Media, which are given to customers but not published publicly, show how fluid and fast moving the success, or failure, of mobile forensic tools can be, and highlights the constant cat and mouse game between hardware and operating manufacturers like Apple and Google, and the hacking companies looking for vulnerabilities to exploit.

Analysis of the documents also comes after the FBI announced it had successfully gained access to the mobile phone used by Thomas Matthew Crooks, the suspected shooter in the attempted assassination of former President Donald Trump. The FBI has not released details on what brand of phone Crooks used, and it has not said how it was able to unlock his phone.

The documents are titled “Cellebrite iOS Support Matrix” and “Cellebrite Android Support Matrix” respectively. An anonymous source recently sent the full PDFs to 404 Media, who said they obtained them from a Cellebrite customer. GrapheneOS, a privacy and security focused Android-based operating system, previously published screenshots of the same documents online in May, but the material did not receive wider attention beyond the mobile forensics community.

For all locked iPhones able to run 17.4 or newer, the Cellebrite document says “In Research,” meaning they cannot necessarily be unlocked with Cellebrite’s tools. For previous iterations of iOS 17, stretching from 17.1 to 17.3.1, Cellebrite says it does support the iPhone XR and iPhone 11 series. Specifically, the document says Cellebrite recently added support to those models for its Supersonic BF [brute force] capability, which claims to gain access to phones quickly. But for the iPhone 12 and up running those operating systems, Cellebrite says support is “Coming soon.”

A SECTION OF THE IOS DOCUMENT. IMAGE: 404 MEDIA.

The iPhone 11 was released in 2019. The iPhone 12 was launched the following year. In other words, Cellebrite was only able to unlock iPhones running the penultimate version of iOS that were released nearly five years ago.

The most recent version of iOS in April 2024 was 17.4.1, which was released in March 2024. Apple then released 17.5.1 in May. According to Apple’s own publicly released data from June, the vast majority of iPhone users have upgraded to iOS 17, with the operating system being installed on 77 percent of all iPhones, and 87 percent of iPhones introduced in the last four years. The data does not break what percentage of those users are on each iteration of iOS 17, though.

Cellebrite offers a variety of mobile forensics tools. That includes the UFED, a hardware device that can extract data from a physically connected mobile phone. The UFED is a common sight in police departments across the country and world, and is sometimes used outside of law enforcement too. Cellebrite also sells Cellebrite Premium, a service that either gives the client’s UFED more capabilities, is handled in Cellebrite’s own cloud, or comes as an “offline turnkey solution,” according to a video on Cellebrite’s website.

That video says that Cellebrite Premium is capable of obtaining the passcode for “nearly all of today’s mobile devices, including the latest iOS and Android versions.”

That claim does not appear to be reflected in the leaked documents, which show that, as of April, Cellebrite could not access from locked iOS phones running 17.4.

The second document shows that Cellebrite does not have blanket coverage of locked Android devices either, although it covers most of those listed. Cellebrite cannot, for example, brute force a Google Pixel 6, 7, or 8 that has been turned off to get the users’ data, according to the document. The most recent version of Android at the time of the Cellebrite documents was Android 14, released October 2023. The Pixel 6 was released in 2021.

A SECTION OF THE ANDROID DOCUMENT. IMAGE: 404 MEDIA.

Cellebrite confirmed the authenticity of the documents in an emailed statement to 404 Media. “Similar to any other software company, the documents are designed to help our customers understand Cellebrite’s technology capabilities as they conduct ethical, legally sanctioned investigations—bound by the confines of a search warrant or an owner’s consent to search. The reason we do not openly advertise our updates is so that bad actors are not privy to information that could further their criminal activity,” Victor Ryan Cooper, senior director of corporate communications and content at Cellebrite, wrote.

“Cellebrite does not sell to countries sanctioned by the U.S., EU, UK or Israeli governments or those on the Financial Action Task Force (FATF) blacklist. We only work with and pursue customers who we believe will act lawfully and not in a manner incompatible with privacy rights or human rights,” the email added. In 2021 Al Jazeera and Haaretz reported that a paramilitary force in Bangladesh was trained to use Cellebrite’s technology.

Cellebrite is not the only mobile forensics company targeting iOS devices. Grayshift makes a product called the GrayKey, which originally was focused on iOS devices before expanding to Android phones too. It is not clear what the GrayKey’s current capabilities are. Magnet Forensics, which merged with Grayshift in 2023, did not immediately respond to a request for comment.

Cellebrite’s Android-focused document also explicitly mentions GrapheneOS in two tables. As well as being an operating system that the privacy-conscious might use, 404 Media has spoken to multiple people in the underground industry selling secure phones to drug traffickers who said some of their clients have moved to using GrapheneOS in recent years.

Daniel Micay, founder of GrapheneOS, told 404 Media that GrapheneOS joined a Discord server whose members include law enforcement officials and which is dedicated to discussions around mobile forensics. “We joined and they approved us, with our official GrapheneOS account, but it seems some cops got really mad and got a mod to ban us even though we didn't post anything off topic or do anything bad,” Micay said.

There is intense secrecy around the community of mobile forensics experts that discuss the latest unlocking tricks and shortcomings with their peers. In 2018 at Motherboard, I reported that law enforcement officials were trying to hide their emails about phone unlocking tools. At the time, I was receiving leaks of emails and documents from inside mobile forensics groups. In an attempt to obtain more information, I sent public records requests for more emails.

“Just a heads up, my department received two public records request[s] from a Joseph Cox at Motherboard.com requesting 2 years of my emails,” a law enforcement official wrote in one email to other members. I learned of this through a subsequent leak of that email. (404 Media continues to receive leaks, including a recent set of screenshots from a mobile forensics Discord group).

Google did not respond to a request for comment. Apple declined to comment.

Techlore - Unsubscribe (lemmy.sdf.org)

After their shameless Synology shilling a couple of weeks ago, today Techlore is trying to sell me Proton Pass.

Is Proton Pass a bad password manager? I don't know. It seems okay, but I have no opinion.

What I do know is that Techlore is affiliated with Proton, which makes their newest 10-minute video - in which they reveal the affiliation only at the last minute - 10 minutes of my life I'll never get back.

Unfortunately, In the business they're in, the merest hint of a bias kind of invalidates any advice they give. As the saying goes, when you point out other people's body odor, you'd better make sure you took a shower yourself.

I'm one of those oddballs who's never joined, but I'm in the market for a new to me bike, and it seems like all the action is on marketplace. Am I screwed, or is there an effective workaround ?

Edit: Not US. There are local alternatives that I know about, but they are worse, please answer question as asked ! Basically I'm thinking of alternative software ala FreeTube, or a way of spoofing facebook to make a dummy account only to be used for this and if so what precautions to take...

Digital privacy seems quite straightforward, because your digital devices are environments you more or less can have complete control over if you want to. But when you're out and about, it's a much more uncontrolled environment. There are cameras everywhere.

I wear face masks everywhere for a combo of protecting myself from illness and privacy. But the limitation is social acceptability. If anything good came out of covid it's the normalisation of face masks, but you are far from unidentifiable if your only face covering is a covid mask. We're lucky that sunglasses and hoodies on their own are fairly normal, but all of the above in combination would draw attention to you. And it's definitely not socially acceptable to walk around in a balaclava.

The other thing is forensic data. If you don't wear gloves, you'll leave fingerprints everywhere, and hair too. I suppose wearing gloves is not particularly seen as weird or suspicious, but it just seems like there are a lot of considerations and challenges with preventing the state from knowing your every move when you leave the house.

What considerations do you make for IRL privacy, if any?

(Not particularly interested in "I don't care about IRL privacy so I don't do anything"—that's fine and your choice, but ofc this question is aimed towards those who do care)

I switched over since I heard it was more privacy friendly than YouTube and have been using the platform for a while without issues, but this cookie banner just popped up. You can opt-out of things like "Access precise geolocation data" but a lot of other information is still shared by third parties and not opt-outable.

It seems "Reject All" is the correct choice here, but I'm not sure if it is the best choice for browser users who have to constantly log back into their accounts.

But as I and others looked closer, and thought about it more deeply, things became concerning.

These logs include:

Your precise GPS locations (which are also sent to their servers).
Your WiFi network name.
The IDs of nearby cell towers (even with no SIM card inserted, also sent to their servers).
Your internet-facing IP address.
The user token used by the device to authenticate with Rabbit's back-end API.
Base64-encoded MP3s of everything the Rabbit has ever spoken to you (and the text transcript thereof).

Basically title. Recently I saw a new option in Chromium website permission settings called "allow access to local network" or something like that and I know some antiviruses on Windows that can list all devices connected to the same WiFi network. I'm usually using Firefox based browsers that obviously don't have the option to disable or enable that access. So can some really invasive websites mine data about my local network, connected devices etc? And if so, what can I do to prevent it except for just disconnecting everything else when visiting such websites?

Hey friends,

I'd like to:

  • Register for a social media account under a client's company name
  • Research the presence companies in the client's industry have on the site
  • Have a reasonable assurance the account will not be linked to my real name nor my network
  • Use a VM for 10-30? hr/mo, short term

I am:

  • US West Coast based
  • Tech savvy but don't code (unless copypasta)
  • Price conscious
  • Privacy conscious in terms of social media companies linking my account and my identity

Assumptions and UnderstandingsGiven the complexity of fingerprinting techniques, I am under the impression logging in to a remote computer and doing all this work from a browser there has one of the highest likelihoods of success. I'd measure success by not getting spammed with work-related ads, whenever I have to disable Ublock Origin at least. It seems likely a social network will know I'm using a remote desktop (based on IP and loading time/delays), but seems difficult for them to understand who exactly is using the cloud machine if I only use it for a singular purpose. I would hope data brokers aren't efficiently tying VM usage back to VM leasers.

I understand a VPS isn't typically suited for GUI usage, and VPNs can leave me more vulnerable to fingerprinting.

Finally, it looks like most of the low-end cloud PC options would support web browsing at a reasonable speed.


Questions:

  • Have I betrayed any misconceptions?
  • Is a cloud PC one of my best options, and if so:
  • Can you recommend a provider and specs?
  • Is there anything I'm missing?

Hi everyone,

I've been checking this forum but I have not managed to find duplicates (I'm using Summit for Lemmy). If that's the case I'll remove this post.

I'm about to start a PhD. I've been told I will be required to partake in publications and other shenanigans. I am not against it, but I'm very concerned about having my full name flying around the internet, as I've always been hesitant of sharing any of that information (real name, pictures, etc).

Ultimately, I only care for potential employers to know that it's actually me the one who has written this or that, which I would happily disclose in private.

What's the usual stance in this situation?

Curious what people think.

Do you think using the GrapheneOS operative system is useless if the user plans to/needs to install Play Store apps anyway?

I think I'm not alone in feeling this way, but sometimes I feel a sense of imposter syndrome because I'm not perfectly private and am dependent on some Play Store apps. This has caused me to question if the transition to GOS is meaningful at all.

Feel free to share your opinion. Cheers! ...posted from my GrapheneOS Pixel.

I have not any prior experience with installing custom ROMs, but after trying it out (and getting stuck, and googling and finding answers) I successfully did it. Below is my home screen if anybody is curious:

I use OpenBoard for my keyboard. Unfortunately I am still dependent on Play Store since some of the apps I need can only be found there. Sometimes it feels meaningless committing to this whole thing because I'm not perfectly private; then I think this is better than using a regular iPhone or Android phone.

So far I'm liking it. I am naturally inclined to feel hesitant about using this as my main phone and plugging in a SIM since it's custom, but I'm slowly making the transition.

Feel free to share any beginners advice or your own experience using GOS for the first time. Cheers!

I'm traveling to the US mainland for the first time in my life in a few weeks.

I am not overly stressed about privacy, but I have read that US immigration can really overstep their boundaries. Are there any simple specific steps to take on my devices to protect my privace when going through US border control?

Remove my main accounts from my phone/tablet and use dummy accounts? Or just removing my biometrics?
