Qubes possibly compromised

[Heather]

Hello, i have reason to believe my qubes install may have been compromised, however, i did not want to bother the security team as i know they are busy, and i do not have any sort of conclusive evidence.

I was downloading some sensitive work files, and during the download, my qubes crashed, and it has been crashing several times after that.

Every time it crashes it shows a black screen with artifacts/graphical glitches.

Additionaly, the xfce top bar is not working and when i try to manualy start it, it shows the following error

GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown:
The name is not activatable

I do not have the technical know-how to investigate this situation on my own and i would greatly appreciate help with this matter.

I have very sensitive information in this machine, and the possibility that it is compromised concerns me greatly.

Your help would be appreciated.

You might want to have a look at this thread:

What's the best way to check if qubes is hacked?I

As the topic says… whats the absolute best ways to check the integrity of a qubes install or if you have been hacked? sys-net, or sys-firewall or dom0 and so on? Any step-by-step guide for tlike that… But i might be paranoid also. I’m no hacker so i can’t tell if i have been hacked really. What’s the best way to check? hat on this forum? I think someone might have hacked my passwords… hmm. I got nothing to hide, but that would be disrespectful, that’s all. You ask for permission, not break int…

GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown:
The name is not activatable

It is known issue, resolved for example

Panel is gone

@Qubes_User171 should start terminal in dom0, execute xfce4-panel. Panel will show up. Then it is needed forcibly to close the terminal regardless of the warning. The panel will disappear and reappear in a flash second. It usually happens when using context menu while on panel which somehow triggers closing the panel without the warning.

It is also known recent issue, but still not resolved

QubesOS freeze, crash and reboots

Well it’s happening for more than 2 months now…

So, most probably you’re not compromised, or most probably too many of us are compromised.
