Query: Characterizing the Landscape of COVID-19 Themed Cyberattacks and
  Defenses   COVID-19 (Coronavirus) hit the global society and economy with a big
surprise. In particular, work-from-home has become a new norm for employees.
Despite the fact that COVID-19 can equally attack innocent people and
cybercriminals, it is ironic to see surges in cyberattacks leveraging COVID-19
as a theme, dubbed COVID-19 themed cyberattacks or COVID-19 attacks for short,
which represent a new phenomenon that has yet to be systematically understood.
In this paper, we make the first step towards fully characterizing the
landscape of these attacks, including their sophistication via the Cyber Kill
Chain model. We also explore the solution space of defenses against these
attacks.
