'North Korea has hacked Pfizer to get information about COVID-19 vaccine and treatment data,' South Korean intelligence official Ha Tae-kyung told reporters. Mr. Ha did not answer questions about when the hack took place or whether the hack was successful.

This is not the first time North Korea has hacked COVID-19. In October 2020, a group of government-sponsored hackers hacked into a major pharmaceutical company, and Mr. Ha said that hacking by North Korea increased by 32% in one year.

Also, it is not the first time that the vaccine information developed by Pfizer is subject to hacking. In January 2021, the European Medicines Agency (EMA) , an EU specialized agency that reviews drugs, was attacked by a cyber attack, and it was found that information on the COVID-19 vaccine developed by Pfizer and BioNTech was leaked.

However, North Korea has officially admitted that it has requested about 2 million doses of vaccine from the WHO-backed vaccine distribution program COVAX . In addition, North Korea is reported to have taken measures such as suspending trade with other countries and installing land mines on the border with China in order to prevent the spread of infection within the country.
