In diary entry "Office maldoc + .lnk" we analyzed a Windows shortcut file (.lnk) and looked for metadata, but it didn't contain much.

Here is another malicious .lnk file that we analyze with lnkanalyser:

This time we have more metadata, under TrackerDataBlock we can find the machine name (frank), a VolumeID and a MAC address.

The MAC address starts with 00:0C:29, that range is assigned to VMware. So we are dealing with a virtual machine.

The target (cmd.exe) has size 301568: this is cmd.exe on Windows 7.
