Personal information from roughly 1.5 billion worldwide Facebook users was allegedly put up for sale following a recent leak.

A member of a known forum for hackers claimed to be in possession of the information in late September and offered to sell it in chunks to others on the forum, according to a report from Privacy Affairs. One user claimed to have gotten a quote of $5,000 for the information of 1 million users.
