While we have a workshop on social engineering for you at DeepSec 2015, we do not do any trainings or exercises before the DeepSec event starts. A speaker alerted us that he got a cold call from a company offering cheap rates for accommodation. In case you have received any call from Exhibition Housing Management (EHM) and Exhibitors Housing Services (EHS), you can safely hang up. Both organisations have been used for scams in the past. Apparently they are alive and kicking.
We thank EHS/EHM for providing exercise material and contact data for use during the conference.
