WikiLeaks founder julian assange has revealed how an intruder tried to break into the Ecuadorian embassy in London where he lives in political asylum.

The Australian-born whistleblower has been living there as a recluse since 2012 and hasn't been seen near the embassy balcony since October last year.

Assange says that was when someone tried to break into the London embassy, where he is living to avoid being extradited to Sweden on allegations of rape.

'It was a 3am on a Monday morning and they climbed up the wall drain pipe and they were opening one of the windows with one their feet,' he told the Kyle and Jackie O breakfast radio show in Sydney.

'There's cameras everywhere but it's pretty weird.'

The 45-year-old computer programmer, who now makes a living exposing state secrets, was interviewed by Kyle Sandilands and Jackie Henderson on KIIS-FM, only hours after rebutted rumours about his death on Twitter.

'Rumours of my death have been greatly exaggerated in a curious plot,' he said on Wednesday.

Julian Assange says conspiracy theories about his death began circulating in October

Assange said conspiracy theories about his health began circulating during October, ahead of the U.S. presidential election race between Donald Trump and Hillary Clinton.

'One was pushed with fabricated, fake documents saying that I was dead, that I was kidnapped and that people should not trust WikiLeaks and should not give it any money because it was now secretly run by the CIA,' he told Kyle and Jackie O on Wednesday.

He has spent the past five years in exile in a bid to avoid extradition to Sweden, which he fears could lead to him being deported to the United States.

Chelsea Manning's 35-year sentence for giving 750,000 documents to WikiLeaks

U.S. President Donald Trump recently described Chelsea Manning as a 'traitor' after his predecessor Barack Obama last month pardoned her for giving 750,000 military and diplomatic documents to WikiLeaks in 2010.

The U.S. Army soldier's 35-year sentence was commuted to seven years, which makes her due for release in May.

'Think about how hard it is to get the president of the United States to commute a 35-year sentence to seven years, what that takes behind the scenes to do,' Assange said.

'We don't like the precedent of sources going to prison.

'It was an amazing victory this year after years of campaigning, we managed to Barack Obama to give Chelsea Manning a clemency.'
