OFFICE DOCUMENTS: MAY THE XLL TECHNIQUE CHANGE THE THREAT LANDSCAPE IN 2022?

   
 * Created 32 minutes ago by AlienVault
 * Public
 * TLP: White

In the last months, security researchers monitored with particular attention

directly loaded by Microsoft Excel, just in one click. This emergent delivery
technique leverages XLL files, a particular file type containing a Microsoft
Excel application ready to be loaded.
