Unfortunately 'Zombie' computers aren't nearly as cool as you might first imagine them to be. They are computers which have been hijacked by cyber-criminals and security vendor McAfee says that it has detected twelve million cases since January of this year. According to McAfee's reports, that puts the number of infected computers up 50% since 2008, with more un-detected cases likely to be out there. It was also reported that the US hosted the largest number of infected computers, with 18% of the total. China isn't too far behind, making up just over 13%. With the expansion of botnets, cyber-criminals have a lot of power to tap into, which can enable them to distibrute large quantities of malicious malware.
While a number of countries have now begun the process of establishing comprehensive strategies with regard to cyber-security, a recent report from Deloitte Touche Tohmatsu (DTT) has emphasized the requirement for a globalized approach to the problem and that solutions need to be implemented with some urgency. It is notable that president Obama has publically made the issue a priority, though it is thought that the release of a 60-day review ordered soon after he took office has been delayed by the recent H1N1 flu crisis. Greg Pellegrino, a global public sector industry leader Deloitte said "This issue is moving so quickly, and with so much at stake economically and in terms of safety and security for people, we don't have 100 years to figure this out."
