A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

So I have a 3700x, I've read about the vulnerability but don't fully understand it. How at risk am I?

If an attacker gets access to your system, they will be able to ensure you can't get rid of their access

It will persist across operating system installs

However, this requires them to get access first

Sounds like it's time for an upgrade. Never know what kind of weirdos are out there. Thanks for the information.

If they get root or admin they can hack the chip itself.

But minor exploits, nada, no issue, you good. Gotta get root to make it happen.

Problem is if you, as they say, get got, you have no way of knowing if they're in your CPU, and no way to fix if they did -- basically gotta trash it and replace.

Not particularly. The exploit requires ring 0 access, if an attacker managed to get that, you are screwed already.

In short, if you're pwned once, you are pwn3d f0r3v#rrrrreeeheehaahaahaa*cough**cough*

These are the kinds of exploits you use to create APT (Advanced Persistent Threats).
