About a month or so back, just before the holiday stretch set in for many of us here in North America, Ars Technica put out an article depicting a new vector for Turla, namely a “Powerful, highly stealthy Linux trojan” that “may have infected victims for years.” I don’t know about you, but to me [...]

December 17, 2014 | By Colin Walker | 8 Comments

Some days I just frackin’ love what I do. Taking a figurative hammer to the metaphorical tough nut in the form of a complex problem and cracking that baby wide open is just plain fun. Getting to use wickedly cool technology to do so is just icing on the cake. Tasty, decadent icing. Whether it’s [...]
