Hackers from 12 countries were behind the attack on the Health Ministry?s electronic prescription service earlier this month, a government adviser said on Thursday.
The head of the Computer Center for Social Security Services (IDIKA), Vlassis Sfyroeras said that hackers from the USA, Argentina, Sweden, Czech Republic, Russia, Kazakhstan, Turkey, Israel, South Korea, Japan, Taiwan and Malaysia attacked the site, causing the equivalent of 3.4 million page views, which resulted in the system overloading.
The attacks took place on April 6, 7 and 9. Sfyroeras said the attack did not lead to any personal information being stolen.
The incident is being investigated by the financial crimes squad (SDOE).
