We are seeing it with all of our users now trying to update.

vaportail commented 6 months ago

Yep, malwarebytes detects it. I assume it has to do with 

    dwTokenRights := uint32(syscall.TOKEN_QUERY | syscall.TOKEN_ASSIGN_PRIMARY | syscall.TOKEN_DUPLICATE | syscall.TOKEN_ADJUST_DEFAULT | TOKEN_ADJUST_SESSIONID)

or surrounding code.

this is commonly found in code that tries to execute with system-level privilege (not just elevated, think TrustedInstaller)

https://github.com/Mr-Un1k0d3r/Elevate-System-Trusted-BOF/blob/main/elevate_x64.c

but of course it has a lot of other uses too...

this code for de-elevation looks interesting, but I am skeptical of the implications

https://stackoverflow.com/questions/44633587/how-to-drop-elevated-privileges-when-i-no-longer-need-them

not proposing as solution for this, idk what the solution is.

might be best to just contact @MalwareBytes about it
