WASHINGTON (Reuters) - A leaker says they are offering information on more than 500 million Facebook Inc users - including phone numbers and other data - virtually for free.

The database appears to be the same set of Facebook-linked telephone numbers that has been circulating in hacker circles since January and whose existence was first reported by tech publication Motherboard, according to Alon Gal, co-founder of Israeli cybercrime intelligence firm Hudson Rock.
