Sometimes the most entertaining (and instructive) stories are ones where the good guys don't necessarily win. Nick Leghorn is an information security professional who has done more incident response than most people would ever hope to see in their lifetime, and not all of it has gone to plan. In this talk Nick will walk through some of the most interesting examples of incident response gone wrong (including at least one incident featured in newspapers around the world) and discuss the lessons learned from each one. Hopefully by learning from these examples we can all prevent the same issues in the future.
