|Occupation||Founder, Hackers for Charity
Long is well known for his background in Google hacking, a process by which vulnerable servers on the Internet can be identified through specially constructed Google searches. He has gained fame as a prolific author and editor of numerous computer security books.
Career in computer security 
Early in his career, in 1996, Long joined Computer Sciences Corporation and formed the corporation's vulnerability assessment team known as Strike Force. Following a short position at Ciphent as their chief scientist, Long now dedicates his time to the Hackers for Charity organization. He continues to provide talks at many well-publicized security events around the world. In recent years, Long has become a regular speaker at many annual security conferences including DEF CON, the Black Hat Briefings, ShmooCon, and Microsoft's BlueHat internal security conferences. Recently, his efforts to start the Hackers for Charity movement have gained notable press attention. His talks have ranged from Google hacking to how Hollywood portrays hackers in film.
Google hacking 
Through his work with CSC's Strike Force, Johnny was an early pioneer in the field of Google hacking. Through specially crafted search queries it was possible to locate servers on the Internet running vulnerable software. It was equally possible to locate servers that held no security and were openly sharing personal identifiable information such as Social Security numbers and credit card numbers. These efforts grew into the creation of the Google Hacking Database, through which hundreds of Google hacking search terms are stored. The field of Google hacking has evolved over time to not just using Google to passively search for vulnerable servers, but to actually use Google search queries to attack servers.
