Tesis (magíster en derecho económico, inversiones, comercio y arbitraje internacional) Universidad de Chile, Universidad de Heidelberg / In 2010 a malicious computer worm attacked Iranian nuclear facilities in Natanz. It was the first computer worm that caused physical damage, and because of this, Iran had to suspend its nuclear program approximately for two years. The case caused great concern among the international community and raised the issue of protecting the population. This paper will address the issues of cyber war and its relationship with International Humanitarian Law and International Human Rights Law.
