A Diary of mine was published today on the SANS Internet Storm Center. In this one, we take a look at how regional travel restrictions impact (or don’t) the number of IP addresses which expose remote access protocols to the internet.

A Diary of mine was published today on the SANS Internet Storm Center. In this one, we take a look at a weakness handling of LNK files in Windows, through which one may force the OS to download an arbitrary file from a remote server any time the shortcut file is displayed.
