LUKS mermaids of remote unlock

Filed under
Security

Recently, I’ve browsed several how-to’s regarding the possibility of unlocking a LUKS root volume remotely using an SSH connection. For reference, the first of its kind is the one for Debian, published at Coulmann.de. Some of these how-to’s were posted to forums and mailing-lists and received many thankful comments from sysadmins wondering how to make their encrypted secure setup also easy to administrate.

The problem with their approach is simple: they asked how to fix their setup, but forgot to ask what they’re trying to protect. Having your root filesystem on an encrypted disk doesn’t protect you from remote exploitation or credential leaks. It just protects you from the risk of someone being able to access your machine locally and steal your data, or just steal the whole machine altogether. Now, if I were an attacker having access to your hardware locally,

I could easily setup a trap for you in less than 5 minutes:

Fedora: The Latest

  • Korora 22 Flash Update
    As we announced when Korora 22 was released, Adobe Flash is no longer included by default.
  • Fedora repository for Doom stuff: Zandronum, Doomseeker, CnDoom
    I had a bit of free time over the last few days, and looked at the current state of the art for Doom on Linux. The awesome Rahul Sundaram has been looking after several Doom-related packages for a while – including the Chocolate Doom package – but there are some things that seem to be commonly used these days that we didn’t have packaged. So I packaged them up, and put them in a new repository!
  • CUDA 7.0 enabled programs for Fedora 22
    I’ve udpated the CUDA version in the Fedora 22 Nvidia repository, it now contains CUDA 7.0.28 along with the cuFFT 7.0.35 patch. Note that from this version, CUDA is x86_64 bit compatible only, so there are no more i386 packages. There is still the cudart library available for 32 bit, but I don’t think it’s worth packaging.
  • Secure Boot — Fedora, RHEL, and Shim Upstream Maintenance: Government Involvement or Lack Thereof
    Note that there are parts of this chain I’m not a part of, and obviously linux distributions I’m not involved in that support Secure Boot. I encourage other maintainers to offer similar statements for their respective involvement.
  • Remi repository is changing
    The "remi" repository exists for > 10 years, it have changed a lot, and some recent changes worth to be explained.
