For 2-3 years now, most malware has satisfied the definition of Organised Crime - it's theft, it's purposeful, it's co-ordinated.
In an August 2006 post, I reported the ACCSS comments and new comments from SANS .
ZDNet now report that Rootkits becoming increasingly complex and operate by stealth. They say:
If you use a Microsoft system and connect to the Internet without extensive protection, you should be afraid, very afraid. And even large organisations who do everything right, are still open to targetted "zero day" attacks. The first Windows Vista security problems are being reported. It's better than their previous efforts, but still contains significant security flaws. The Whitehouse mandated a minimum security configuration for all US Federal Government Vista destops.
Rootkits -- malicious software that operates in a stealth fashion by hiding its files, processes and registry keys--have grown over the past five years from 27 components to 2,400, according to McAfee's Rootkits Part 2: A Technical Primer (PDF).
