Plenty of Phish in the Sea: Analyzing Potential Pre-attack Surfaces

Advanced Persistent Threats (APTs) are one of the main challenges in modern computer security. They are planned and performed by well-funded, highly-trained and often state-based actors.

An essential part of this initial data collection phase is the identification of possible gateways to intrude the target.
