We've added a new icon to the 13_02 set for an upcoming PCI pattern. We now have a White Hat to represent an ethical 'hacker' (I place it in quotes as the term originally meant computer user who hacked together code quickly to achieve a given objective, and has somewhat changed meaning in recent years), a.k.a Pen Tester.
The black and white hat design took inspiration from the Mad Spy vs Spy comic - a firm favourite when I was younger, especially the rather good game on the C64.
The icon has been added to the icon library in both SVG and PNG formats and is included in the icon packs.
