What's the common or recognized name for a vulnerability on a platform where someone can build trust and than pillage/exploit that trust for profit or information? It's driving me crazy, and I constantly forget it every time I want to use it, and than I'll read it in a paper a few months latter.
the attacker subverts the reputation system of a peer-to-peer network by creating a large number of pseudonymous identities, using them to gain a disproportionately large influence. A reputation system's vulnerability to a Sybil attack depends on how cheaply identities can be generated, the degree to which the reputation system accepts inputs from entities that do not have a chain of trust linking them to a trusted entity, and whether the reputation system treats all entities identically.
Subterfuge is the act of using deceit in order to reach a goal.
You are being deceitful in nature when you legitimately build trust within an environment you plan on harming later.
