North Korean hackers tried to crack into computer systems belonging to Pfizer in efforts to access details regarding a coronavirus vaccine, according to Fox News.

Seoul’s National Intelligence Service “briefed us that North Korea tried to obtain technology involving the Covid vaccine and treatment by using cyberwarfare to hack into Pfizer,” said Parliament member Ha Tae-keung.

Pfizer and The U.S. State Department did not immediately respond.

U.N. security experts recently discovered that North Korean Cyber hackers stole $316 million.

Kim Jong Un claims that North Korea has been immune to coronavirus and says that the country has had no cases.

North Korea last year imposed a border lockdown and increased quarantine measures in an effort to prevent a COVID-19 outbreak.

Pfizer aims to make two billion doses of the COVID-19 vaccine this year, according to the international news agency headquartered in Paris, France.
