CloudPassage Inc. organized an exercise to demonstrated how it is simple the live server exploitation of cloud environments poorly configured. The Gauntlet experiment involved 367 ethical hacking participants from 41 different countries over the course of 23 days in September 2013. The winning hacker obtained full control of the cloud architecture exploiting a weakly protected administrative web interface. The success of the attack is attributable to unpatched flaws and misconfigured systems, the hackers have compromised with success the server under four hours. The simulation exposed more than security issues, 90 of which were successfully validated as remote exposures.”]
