"Attackers have hacked the servers of Australian Web hosting provider MD Web Hosting (mdwebhosting.com.au), embedding malicious code to spawn "link farms" on its customers' sites, according to news site, Australian IT (australianit.news.com.au)."

"The hackers gained access to about five servers which failed to have the correct security profiles. To make matters worse, the company's IP blocking systems and firewalls were not up to par, says Najda. The issue, which was resolved earlier this week, affected only between five to ten percent of its 20,000 customers, he says."
