Nothing at all is safe from the root account, or from any user that can elevate to root. Think of the root account as the system itself - the thing you’re trying to protect may be encrypted and safe at rest if you’ve brought it in from elsewhere, but as soon as you enter a password and decrypt it, you’re handing that password and decrypted data over to a system fully controlled by that root account.

Linux@lemmy.ml•Looking for a tool to auto-sort files using INDEX.md as a mapEnglish
9·5 days agoUnless there’s more information on what kind of files and what kind or sorting needs to be done, this sounds like something that could be done with a simple shell script.
(I wouldn’t trust an ai agent to do it with accuracy, but I’m the kind of luddite that doesn’t trust an ai agent at all.)

Asklemmy@lemmy.ml•Is there a psychotherapy session or series where you can be a fly on the wall for legit actual psychotherapy session(s) that have been released by the therapist+patient similar the IFS Live podcast?English
5·13 days agoWhere Should We Begin? is a podcast by the psychotherapist Esther Perel, where each episode is a full couple’s therapy session with an anonymous couple. It’s nice, and sounds like a match for your question.

Privacy@lemmy.ml•I was a week away from buying a Pixel Pro 10 for GrapheneOSEnglish
61·14 days agoFrom the grapheneos faq section on device support, which details the kinds of hardware and firmware security features required and present on pixels (but may be missing on other devices):
Hardware, firmware and software specific to devices like drivers play a huge role in the overall security of a device. The goal of the project is not to slightly improve some aspects of insecure devices and supporting a broad set of devices would be directly counter to the values of the project. A lot of the low-level work also ends up being fairly tied to the hardware.
Non-exhaustive list of requirements for future devices, which are standards met or exceeded by current Pixel devices:- Support for using alternate operating systems including full hardware security functionality
- Complete monthly Android Security Bulletin patches without any regular delays longer than a week for device support code (firmware, drivers and HALs)
- At least 5 years of updates from launch for device support code with phones (Pixels now have 7) and 7 years with tablets
- Device support code updated to new monthly, quarterly and yearly releases of AOSP within several months to provide new security improvements (Pixels receive these in the month they’re released)
- Linux 6.1, 6.6 or 6.12 Generic Kernel Image (GKI) support
- Hardware accelerated virtualization usable by GrapheneOS (ideally pKVM to match Pixels but another usable implementation may be acceptable)
- Hardware memory tagging (ARM MTE or equivalent)
- Hardware-based coarse grained Control Flow Integrity (CFI) for baseline coverage where type-based CFI isn’t used or can’t be deployed (BTI/PAC, CET IBT or equivalent)
- PXN, SMEP or equivalent
- PAN, SMAP or equivalent
- Isolated radios (cellular, Wi-Fi, Bluetooth, NFC, etc.), GPU, SSD, media encode and decode, image processor and other components
- Support for A/B updates of both the firmware and OS images with automatic rollback if the initial boot fails one or more times
- Verified boot with rollback protection for firmware
- Verified boot with rollback protection for the OS (Android Verified Boot)
- Verified boot key fingerprint for yellow boot state displayed with a secure hash (non-truncated SHA-256 or better)
- StrongBox keystore provided by secure element
- Hardware key attestation support for the StrongBox keystore
- Attest key support for hardware key attestation to provide pinning support
- Weaver disk encryption key derivation throttling provided by secure element
- Insider attack resistance for updates to the secure element (Owner user authentication required before updates are accepted)
- Inline disk encryption acceleration with wrapped key support
- 64-bit-only device support code
- Wi-Fi anonymity support including MAC address randomization, probe sequence number randomization and no other leaked identifiers
- Support for disabling USB data and also USB as a whole at a hardware level in the USB controller
- Reset attack mitigation for firmware-based boot modes such as fastboot mode zeroing memory left over from the OS and delaying opening up attack surface such as USB functionality until that’s completed
- Debugging features such as JTAG or serial debugging must be inaccessible while the device is locked

Linux@lemmy.ml•Dirty Frag: Universal Linux LPE - allows any unprivileged local user to gain root access on a vulnerable Linux system - no patch availableEnglish

26·17 days agomodprobed-db can create a profile of the kernel modules that get loaded by your system over time. You can feed that directly into
make localmodconfigto build a kernel that only includes those modules, or use the data to build a modprobe whitelist.

Privacy@programming.dev•Where to buy a non-Apple, non-Google smartphoneEnglish
51·20 days agoThat’s the problem, unfortunately - being comparably secure to Debian isn’t very secure at all. The state of linux desktop security is very much a nightmare (madaidan’s insecurities is a good primer everyone points to, though you should take it with a grain of salt and it’s a few years old), and without security you’re an exploit away from having no privacy either.
So we’re left with few options, none of them ideal, while the world becomes increasingly more difficult to be participate in without making android or ios a part of your life:
- Use a stock android phone, which is just straight up and unabashedly a spying device meant to milk you for value like a dairy cow. Sacrifice privacy for convenience.
- Use an iphone, which is the same thing shrouded in a layer of niceness. Sacrifice privacy for convenience and a bit more security.
- Use an android variant that focuses on freedom, like lineageos. Sacrifice a bit of convenience for some freedom and some privacy.
- Use grapheneos. Sacrifice a bit of convenience for security, some freedom, and some privacy.
- Use a linux phone, running something like postmarketos. Sacrifice security for freedom and privacy.
Read up on the options, understand the realities, and choose the tradeoff that best fits your preferences and lifestyle.

Open Source@lemmy.ml•Stop New York's Attack on 3D Printing - EFFEnglish
421·1 month agoMore laws written by people who have zero fucking idea what they’re writing laws about.
But root can scrape that password as soon as you enter it, and has access to that encrypted data as soon as you decrypt it. That’s what I’m saying.
If you think anything on a *nix system is “safe” from root or a user that can elevate to root, you’re deluding yourself with wishful thinking.
