However, ZDNet UK has found that the service also lets users carry out vulnerability scans on other people's computers. Though Qualys said it has put a number of preventative measures in place to stop this, it hinted that this was possible.
"There are a number of precautions we have taken to avoid abuse, such as the e-mail registration process, the click-through (you confirm that you have permission to scan the device), and the audit trail," said Gerhard Eschelbeck, vice president of engineering at Qualys. "Nevertheless, the Internet has an open architecture, and there are many free tools on the Internet for download allowing anybody to perform a scan on the Internet completely stealthily without any of these precautions."
Eschelbeck told CNET News.com that hackers who want to use a scanning tool for malicious activity are not likely to use a commercial scan service such as that offered by Qualys, because of the audit trail that's created through the registration process. "They would most likely opt for one of the free scan tools that can be used stealthily," he said.

Research from SANS found that online criminals have turned their attention to antivirus software and media players, rather than just the operating system or browser, in order to take control of people's computers. But hackers are also continuing to find holes in Microsoft Windows and other operating systems.
"These critical vulnerabilities are widespread, and many of them are being exploited right now," said Alan Paller, director of research for the SANS Institute. "We're publishing this list as a red flag for individuals and IT departments who may be unaware of these vulnerabilities, or mistakenly believe their computers are protected."
