The hacker, who goes by the moniker Mak Man and appears to be based in Lahore, Pakistan, posted a link to a searchable database of Gaana user details on his Facebook page. Enter a user’s email address and it spits out their full name, email address, MD5-hashed password, date of birth Facebook and Twitter profiles and more.

The hack appears to be a SQL injection-based exploit of Gaana’s systems, but the intention behind it is unknown. The database shows more than 12.5 million users are currently registered on Gaana.
