What does "hijack" mean in OS X logs?

Question

macOS

I saw an interesting line in the OS X log, I can not understand what's wrong. Here are some lines:

Dec  1 23:18:37 mbp-admin com.apple.launchd.peruser.502[157] ([0x0-0x37037].org.keepassx.keepassx[616]) <Notice>: Exited: Killed: 9
Dec  1 23:24:18 macbook defaults[749] <Warning>: 
  The domain/default pair of (/Users/Sk8er/Library/Preferences/loginwindow, AutoLaunchedApplicationDictionary) does not exist
Dec  2 00:41:18 macbook com.apple.launchd.peruser.502[157] (com.apple.SystemUIServer.agent[181]) <Warning>: The following job tried to hijack the service "com.apple.tsm.uiserver" from this job: 0x7fca1ca00080.anonymous.loginwindow

Actually, the last line, namely "hijack", attracted attention. What is it?
It's just that there is a little paranoia, the mail was recently taken away, but I still don't understand how. I try to monitor all logs.

In general, TSM = Text Service Manager. Uiserver is responsible for the icons on the right side of the menu bar. The message itself means that some process is trying to access all this. A list of these processes can be found in /Library/LaunchAgents/.
But in general, you can definitely guarantee that this message has nothing to do with hacking.
