### Scheduler ### Scheduler
The [Windows scheduler](http://support.microsoft.com/kb/313565) can be used to further compromise a system. It usually runs at the SYSTEM account privilege level. According to Val Smith's and Colin Ames' [BlackHat 2008 presentation (page 58)](http://www.blackhat.com/presentations/bh-usa-08/Smith_Ames/BH_US_08_Smith_Ames_Meta-Post_Exploitation.pdf), you can remotely schedule tasks using the commands below.

### Sticky Keys (Requires reboot) ### Sticky Keys (Requires reboot)
Sticky keys on Windows systems are activated when the user presses the SHIFT key 5 times. Here, according to the [posted slides](http://www.slideshare.net/mubix/windows-attacks-at-is-the-new-black-26665607), you replace the sethc.exe binary with your own binary (cmd.exe maybe?) and, when SHIFT is pressed 5 times, your binary is executed. Your binary will execute as SYSTEM and needs to replace the `%WINDIR%\System32\sethc.exe`. Sticky keys on Windows systems are activated when the user presses the SHIFT key 5 times.

This technique uses registry entries to switch the binary that the sticky keys executes. Its real advantage is that it does not require a reboot for the switch to take place.
