So I won’t be riding a train anytime soon

Posted on January 5, 2016 by robertwilkie

Some folks in Russia did a presentation on security flaws on train systems (subways too).  I am only a quarter way thru the material, but yeah…no trains for me. http://www.theregister.co.uk/2016/01/04/irked_train_hackers_talk_derailment_flaws_drop_scada_password_list/
