  • So first, let me be clear - I don’t know if an alternative to that software you first brought up. But some of our earlier CTFs had a similar issue with isolation.

    We ended up spinning up new VLANs per contestant, each having a single Kali Linux VM with xrdp, along with each contestants target systems. Our router/fw blocked all access in/out of those VLANs, save for RDP/SSH traffic from our Apache Guacamole server on the DMZ.

    So contestants would hit our portal (Guacamole), then from there connect into their own dedicated Kali instance and environment.

    Later, we had to make additional fw exemptions for our scoreboard/docs, etc.



  • I found it myself, Note that if you’re on a Steam Deck (like I am), you’ll need to go to desktop mode.

    1. Go to Steam, then Settings
    2. Scroll down to Compatiblity, then look for the two toggles: Enable Steam Play for supported titles, and Enable Steam Play for all other titles. Ensure both are checked.
    3. I also noticed that my “Run other titles with:” was not set to the latest Proton, but the dialbo 4 proton. Not sure if this made a difference?


  • I put grapheneos on my old Pixel 6 as a “Yolo” phone for a Infosec conference this past year.

    It’s very… okay for apps. You effectively have two options, install a third party app store (F-Droid), or setup a new profile with Google services enabled and use Play store over on that.

    GApps alternatives are mixed quality - nothing really beats Maps (at least in the US), but other things like Chrome are easily replaced with DuckDuckGo browser or Firefox.

    It was an interesting experiment to see if I could go Google apps free, and it worked okay for 4 days, but going full time to it would be rough.
