A reasonably general term for any attack that singles out an audience based on knowledge known or inferred about them. This could range from thousands of individuals who all work for a given company, where it can be inferred that they have a relationship with a vendor known to supply services to the organization. Or it could be a very small number of individuals where some additional information is known – for example, top executives and a key supplier or external legal counsel. See also Showshoe Attack, Spear Phishing.
