Selfhosted

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).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

I set up a quick demonstration to show risks of curl|bash and how a bad-actor could potentially hide a malicious script that appears safe.

It's nothing new or groundbreaking, but I figure it never hurts to have another reminder.

After gaining initial access, the malicious cyber actor deployed malware that scanned the environment for sensitive credentials.

So as I said, the keys got compromised. Thats what i said in the second post.

What you said is the key infra needs to get compromise. I do not need to own the PKI that issued the certs, I just need the private key of the signer. And again, this is something that happens. A lot. A software publisher gets owned, then their account is used to distribute malware.

To achieve a compromised update you either need to compromise the update infrastructure AND the key or the infratstructure AND exploit the local updater to accept the invalid or forged signature.

As i said, to compromise a signature checked update over the internet you need to compromise both, the distributing infrastructure AND the key. With just either one its not possible. (Ignoring flaws in the code ofc)

Take a look at Shai Hulud. All the attacker had was the key.
