Portugal’s General Staff of the Armed Forces (EMGFA) has been targeted by a“prolonged and unprecedented”cyber attack, resulting in the leak of a raft of secret NATO documents, local media outlets reported on Thursday.
According to Diario de Noticias newspaper, the Portuguese government was not even aware of the attack until the US informed it of the breach, which has been classified by the nation’s authorities as“extremely serious.”
The outlet’s sources claim that it was the US intelligence community that found“hundreds”of confidential or secret NATO documents put up for sale on the dark web. According to the report, the notice on the discovery was sent directly to Antonio Costa, the nation’s prime minister, last August.
A spokesperson for the US embassy in Lisbon would neither confirm nor deny the report, saying they do not comment on intelligence matters.
