Downing Street has said it is committed to seeking a diplomatic solution with Ecuador over the stand-off. William Hague, U.K.'s foreign secretary, has made it clear Britain is obliged to extradite Assange to Sweden to face questioning over allegations of sexual misconduct, which he denies. Assange fears being transferred to the United States if he travels to contest the allegations.
The WikiLeaks founder has been in the embassy in Knightsbridge since mid-June and on Sunday addressed crowds of supporters from the balcony. The speech, in which Assange took aim at the U.S. and U.K. governments, has proved to be a rallying cry for Assange's online supporters.
One Twitter account with 145,200 followers which is linked to the loose-knit group on Tuesday tweeted a picture of a man wearing an Anonymous mask, holding aloft a "Free Assange" poster outside what appeared to be the Ecuadorian embassy in London. Another Anonymous Twitter account, which has 281,000 followers, tweeted during the Free Assange attacks: "We're living in oppressive times. Sadly there's no other option than fighting even if that means being outlawed."
Anonymous first came to prominence through its online attacks in support of Assange in December 2010, after WikiLeaks released part of a huge cache of diplomatic cables.
The hacking collective subsequently targeted global finance websites including Visa and PayPal after those companies severed links with the whistleblowers' website.
A Home Office spokeswoman said: "The Home Office website was not hacked. It was targeted by protesters on Monday night but only experienced very minor interruption to the service.
"We had measures in place to protect the site and no other Home Office systems were affected."
