1. A method for automatic detection of phishing websites, comprising:

  • monitoring network traffic;

    detecting within the network traffic a sequence of network traffic events, wherein such sequence comprises;

    an initial request from a network address to a first requested network address;

    a first response to the initial request from the first requested network address at a first time; and

    a second request from the network address to a second requested network address at a second time subsequent to the first time;

    classifying the first requested network address as a potential phishing website;

    wherein the classifying comprises;

    determining that the second requested network address is not related to the first requested network address; and

    determining that a time difference between the second time and the first time is smaller than a defined time value, wherein the defined time value is smaller than a time lapse between a change from one requested network address to another when such change is initiated by a human user; and

    taking one or more protective measures in response to the classifying, wherein the one or more protective measures comprises blocking the first requested network address.
