The interviewing process can be mentally draining. You have to look your best, say the right things, and prove that you’re the best person for the job. When I interview candidates, I love to come up with the one crazy question that isn’t on the usual list of questions that might be asked. I probably won’t be able to use it now since I’m going to disclose it here, but here goes: “If you were a tree, what type of tree would you be and why?” I don’t expect candidates to be experts in forestry or dendrology because there is no right or wrong answer, but I do like to hear what people can come up with off the top of their head. If you think that question is weird, how about this one? “Is it ever possible that (a== 1 && a ==2 && a==3) could evaluate to true in JavaScript?” Jasiel Spelman from our Zero Day Initiative came across this question on a post he read that is being asked during interviews at major tech firms. He takes a stab at answering the question in his latest blog: Inverting Your Assumptions: A Guide to JIT Comparisons.

Microsoft Security Updates There are seven new zero-day filters covering four vendors in this week’s Digital Vaccine (DV) package. Microsoft released 67 security patches covering Internet Explorer (IE), Edge, ChakraCore, Windows, Visual Studio, Microsoft Office and Office Services and Web Apps, and the Malware Protection Engine. Of these 67 CVEs, 24 are listed as Critical, 42 are rated Important, and one is listed as Moderate in severity. Seven of these CVEs came through the ZDI program. The following table maps Digital Vaccine filters to the Microsoft updates. You can get more detailed information on this month’s security updates from Dustin Childs’ April 2018 Security Update Review from the Zero Day Initiative:
