How did the Internet change the everyday work of a security researcher?

Every May 17th is World Telecommunication and Information Society Day, which attempts to raise global awareness on how the Internet and new technologies changed our society, and the opportunities they gave to improve our lifestyle. This special date, also known as Internet Day in some Spanish-speaking countries, is an opportunity for us at ESET to celebrate its existence by remembering what it was like to work in securitybefore the Internet appeared.
