Tamer Şahin

Tamer Şahin (born August 10, 1981 in İzmir, Turkey) is a Turkish hacker.

Şahin's interest in computers started when he was 13 years old.

First, he hacked internet service provider Superonline and caused the system to be out of service for 7 days in 1999.

In late of 2001, he was put in court by claim of hacking one of the oldest banks of Turkey, The Osmanlı Bankası, now part of Garanti Bank. He left "t.ş was here" message on the website of bank and also published the personal photos of all customers which had been kept on bank systems. Several national print and visual media covered this. Charges against him were dismissed due to lack of evidence.

He entered into the systems of Microsoft's Network Operations Center in 2002 and he published personal e-mails of Bill Gates and Steve Ballmer and also secret documents about Hotmail and other projects on Internet.

After all of these, he has emphasized on his own professional business life and his studies on information security still go on. He has published nearly 50 security announcements on various sources.

His life experience has been handled as projects at Istanbul Technical University, Işık University (Istanbul) and the American Collegiate Institute (Izmir). His studies and social reflections of them have been analysed with documents and presentations as lesson scopes.

Şahin lectures about being a hacker and its philosophy at universities and he gives consultant services to firms (information security contracts stay always confidential) about information security. He wrote his own life story in the book called "Hacker'ın Aklı". The book is published by Doğan Kitap.

A documentary film was made by Coskun Aral and his team about Şahin's life and hackers. Şahin writes columns for the technology magazine T3 Turkey.
