Nothing new; most hacks aim at money.
Extorsion (or blackmail) is very profitable. see Tom Espiner, “Schneier: Cyber-extersion on the increase” ZDNet (23 january 2008) http://news.zdnet.co.uk/security/0,1000000189,39292357,00.htm
as well as corporate espionage, ZDNet (7 january 2008) http://resources.zdnet.co.uk/articles/0,1000001991,39291900,00.htm
and ZDNet (28 January 2008) where Greek Police arrested a hacker selling the corporate secrets of Dassault (French military company) http://news.zdnet.co.uk/security/0,1000000189,39292445,00.htm
and in general, about profits made by selling hack services and other tools: “Cracking open the cybercrime economy” (14 December 2007)
And when it is not hacking, it is modifying data, for revenge… An employee in the US was found guilty of computer damage and got 30 months imprisonment, a particularly harsh sentence comparing to customary sanctions applied (9 January 2008) http://news.zdnet.co.uk/security/0,1000000189,39292027,00.htm
And from time to time, political motives are not forgotten: “Hackers crash Panama’s National Assembly website” (22 January 2008) http://news.zdnet.co.uk/security/0,1000000189,39292320,00.htm
