It seems like a hacker called "Gabriel" had published the final ending of the saga in the Internet.

He infiltrated the London office computer system of Bloomsbury, publishers of the Harry books.

The individual claims to have hacked into Bloomsbury and downloaded a digital copy of 'Harry Potter and the Deathly Hallows', the seventh and final book in the series by JK Rowling.
The hacker has posted what he claims are the final secrets of the Harry Potter saga, with key details of the plot, on a website called InSecure.org. And as far as today's morning no comments were made by Bloomsbury leaving the doubt if the plot is true or not.

Now we'll have to wait until 21st July to see the veracity of what he is claiming or is just another scam to gain popularity.
