The industry should reconsider. Not saying one should disclose ones counter-measures, but if the standard practice of keeping secrets amongst industry connected VIPs is the wise choice it's not working very well.
I'm just saying it's not good to post these postmortems publicly. "We got hit by X. We did Y." Now when Q comes along to attack you, they know what not to do and also know how you mitigated X so they can more efficiently attack you. The EV from posting attack postmortems is just not there.
