The alleged attack took place in Australia last year and has been blamed on Russian security service agents.
According to reports, the CIA officials - one of which being among the agency's top five highest ranking individuals - had been staying at a hotel room during a visit to Australia when they began experiencing a strange ringing in their ears and felt inexplicably nauseous.
The symptoms echoed those of what has now become known as 'Havana syndrome', which is named after the symptoms experienced by US and Canadian embassy personnel in Havana, Cuba in late 2016 and which ultimately caused a breakdown in relations between Cuba and the United States.
At the time, it was thought that some sort of sonic or microwave-based weaponry had been used to make the diplomats ill and this latest incident in Australia could very well be the same thing.
Adding to such suspicions is the fact that agents with Moscow's Federal Security Service (FSB) were reportedly within the vicinity of the hotel room at the time the officials became ill.
The same thing happened again when the two agents later traveled to Taiwan.
"I think what we are seeing here is something that is most likely from the Russians, who seem to frankly care almost nothing of the consequences of aggressive intelligence actions," said Peter Jennings from the Australian Strategic Policy Institute.
"This is lifting the levels of Cold War-style conflict to new highs."
"If we're actually engaging in things that amount to physical assaults on diplomats and intelligence officials, that's a new thing that we've really not seen before."
