Web site defacement has become a common threat for
organizations
exposed on the web. There exist several statistics that indicate the
number of incidents of this sort but there is a crucial piece of
information still lacking: the typical duration
of a defacement. Clearly, a defacement lasting one week is much more
harmful than one of few minutes. In this paper we present the results
of a two months monitoring activity that we performed over more than
62000 defacements in order to figure out whether and when
a reaction to the defacement is taken. We show that such time tends to
be unacceptably long---in the order of several days---and with a
long-tailed distribution. We believe our findings may improve the
understanding of this phenomenon and highlight issues deserving
attention by the research community.
