arun is a Swiss-army knife for privilege escallation. The child process is executed with maximum available privileges. This is suitable for performing administrative tasks.
Priority, window visibility and integrity level can
also be specified. Optionally the Administrators
group can be removed from
the new process by stripping it or using a linked token, where it is available
or removed.
Available privileges can only be enabled or disabled. Once a privilege is
removed, it can not be restored. However if a process token has ownership of the
Administrators
group, it can install a service to start a child process
restoring any privileges that had been removed: -e
-s
-S
. Since services
run with System
privileges, they can take the role of any existing process,
by duplicating its token: -t PID
. It is also possible to execute a process in
another session: -n
. Use -D
to specify a
window station and Desktop.
Console applications are usually run in the parent console. To detach the child,
and run in a new window, use -d
.
There is a hack to elevate selected programs automatically, by assigning a
debugger under Image File Execution Options
. In that case, specify the -G
flag.
Otherwise the system will attempt to execute the process indefinitely.
Users who have disabled Animate controls and elements inside windows
, might
experience poor performance in Office 2013-2016 applications. The workaround is to
enable animations, then start an Office application, and disable animations shortly
after that: -A
.
