Would use it for piracy, not if you need good privacy. It's good enough to avoid a complaint letter from your ISP when torrenting, but can you be sure that they don't sell your data to advertisers? I don't know. Will they respond to a law enforcement subpoena? Probably.

Outlook.

Thankfully Thunderbird, although most folks here just use the Roundcube web client.

With a giant signature that includes an embedded image.

They are auto-generated and enabled for everyone. Typical corporate bullshit I guess.

Also the image is a 2400px image that has been resized using width and height attributes.

It's a portrait (that thankfully has been downsized and compressed so much, that it's barely recognizable (thank goodness, because it's a horrific photo)), as well as a photo of my physical signature. Oh god do I hate emails and email signatures. And fuck my company for wanting emails to look "authentic" and including this stupid ass signature.

That rate limiting can easily be bypassed by an attacker. In order to be effective, the rate limit needs to be enforced by tamper-resistant hardware, i.e. a secure element. Here are some of the requirements for a secure element: https://developer.android.com/privacy-and-security/keystore#StrongBoxKeyMint

An implementation of StrongBox KeyMint must contain the following:

Its own CPU
Secure storage
A true random-number generator
Additional mechanisms to resist package tampering and unauthorized sideloading of apps
A secure timer
A reboot notification pin (or equivalent), like general-purpose input/output (GPIO)

For details, I recommend reading:

Only devices with a proper implementation of a secure element (Titan M2, i.e. Pixel 6 or later, or the Apple SEP, i.e. iPhone 12 or later) are actually resistant to brute-force attacks by forensic data extraction tools, such as Cellebrite or GrayKey. GrapheneOS has obtained some internal documents from multiple forensics companies. They published the Cellebrite docs at https://discuss.grapheneos.org/d/14344-cellebrite-premium-july-2024-documentation

Specifically, I recommend looking at this chart:

It clearly shows that data cannot be extracted from iPhones with the SEP, unless the device is in the AFU state, meaning that the encryption keys are kept in memory.

Those are the charts for Pixels:

Sandboxed Google Play is one of the key features of GrapheneOS. So far no other OS has allowed users to enjoy the full functionality of Android Auto, the Pixel LPA for managing eSIMs, and the Google Mobile Services suite (not talking about the other Pixel OS stuff) with the only exception being GPay, without full sandboxing, and without granting excessive privileges (SGP is unprivileged, the eUICC LPA obviously requires higher privileges for managing eSIMs, but it's fully sandboxed and can't communicate with Play services, or access the internet)

GrapheneOS has criticized Fairphone from a security perspective for a long time, long before any partnerships with OEMs were ever made. GrapheneOS chose to partner with this specific company (which they don't want to broadly disclose yet) because they have shown, that they actually care about security, and are willing to invest time and effort to meet the GrapheneOS device requirements, not the other way around.

the team refuses to use reverse-engineered hardware interfaces

Small correction: Current and future GrapheneOS releases for Pixels are produced by reverse-engineering Pixel OS releases. adevtool was developed together with the developer of ProtonAOSP back then, to automate extracing several components from the stock Pixel OS.

This is incorrect. The sideloading checks are implemented in Play Protect, which needs elevated privileges to function. On GrapheneOS, Google Play services run with normal privileges, just like any other user-installed app. This means, there are no Play Protect checks in GrapheneOS, and there will never be. It would only be possible on ROMs, such as LineageOS with Gapps, where Play services are installed as system apps, running with higher privileges than all other apps.

Nothing needs to be disabled, since it isn't present in GrapheneOS in the first place. The sideloading checks are implemented in Play Protect, which needs elevated privileges to function. On GrapheneOS, Google Play services run with normal privileges, just like any other user-installed app.

Thanks for reminding me!

I actually wasn't testing anything, I just needing to make a post using my Lemmy.world account, so I could appoint it as moderator (my main account is on lemmy.dbzer0.com). This community actually wasn't created by me. I had previously created a Bazzite community on dbzer0, but then Draconic_NEO created this community on LW and made me mod. I couldn't handle reports though, since they don't federate properly. I have hopefully sorted this out now, by creating an LW account for moderation only, which I now finally have appointed as moderator.

There are several supported apps, such as Curve Pay, PayPal, and banking apps that have their own tap-to-pay implementation.

You can also use the contactless payments supported tag when searching the GrapheneOS banking app compatibility list on GitHub. https://github.com/PrivSec-dev/banking-apps-compat-report/issues?q=is%3Aissue+label%3A%22contactless+payments+supported%22
