In one of the older versions of the code base was a Vagrant config file that contained a second AWS key pair that then gave him access to seemingly everything. Most of all relax, speak clearly and be positive. Internal server exposed to the Internet The story begins when the attacker was tipped off to an Internet accessible server sensu.
