The question of who is responsible for patching may not be clear when the business, school or church sets up a website at a web-hosting provider, often with help from a consultant, Conway points out. There may be re-sellers in the mix as well.
The high number of compromised websites today is so substantial that hacked hosting accounts have become a commodity sold in the cyber-criminal underground, says Conway. According to Cloudmark's estimate, 60% of hacked domains are still under the control of spammers one month after compromise. Cloudmark says it can provide hosting companies with a list of compromised domains on their servers for remediation purposes.
