"The word "hacking" has two definitions. The first definition refers to the hobby/profession of working with computers. The second definition refers to breaking into computer systems. While the first definition is older and is still used by many computer enthusiasts (who refer to cyber-criminals as "crackers"), the second definition is much more commonly used. In particular, the web pages here refer to "hackers" simply because our web-server logs show that every one who reaches these pages are using the second definition as part of their search criteria. "
By extension, it has now come to mean unauthorised access to technological devices other than just computers.
You need to keep in mind that journalists are notorious for their sloppy use of language, especially when it comes to technical terms.
