| `%SystemRoot%\System32\wbem\mof\` | Taken from Stuxnet: http://blogs.iss.net/archive/papers/ibm-xforce-an-inside-look-at-stuxnet.pdf Look for Print spooler vulnerability. |

| `echo $PATH` | Check the $PATH environmental variable. Some directories may be writable. See: https://www.htbridge.com/advisory/HTB23108 |

| `msiexec.exe` | Idea taken from here: http://goo.gl/E3LTa - basically put evil binary named msiexec.exe in Downloads directory and when a installer calles msiexec without specifying path you get code execution. |
