Today I had the privilege of presenting at DerbyCon 2015 in the stable talk track. My talk, "Detecting Spear Phishing Attacks Using DNS", was based on a blog post from earlier this year. The turnout was excellent, the room was packed, and I had a great audience. If you were there, thank you!
The slides for the talk have been uploaded to SlideShare. You can find them here: Detecting Spear Phishing Attacks using DNS.
I'll be giving this talk again in November at BSides Winnipeg.
