Linux has finally achieved enough market penetration to be worthwhile to attack. Not desktop market penetration per se, but market penetration nonetheless. The particular platforms where it can be found with relative frequency fundamentally contribute to the reasons the attacks are successful – they are home user devices that aren’t likely to be updated. I surmise that within the next three to five years, we’ll see a tipping point where many of these network devices will default to automatically update themselves in much the same manner our operating systems, browsers, and many applications in both the mobile and desktop realm do today.
