Hacktivist collective group Anonymous claims to have leaked personal details of US presidential candidate Donald Trump. The group has declared war against Trump under a campaign with the hashtag #OpWhiteRose. The White Rose Society was a non-violent resistance group in Nazi, Germany and was known for its anti-Nazi pamphlets and graffiti during World War II. Most of the information provided by Anonymous has been circulating on the Internet since at least late last year, including his New York cell phone number and address on 5th Avenue.
