Webmasters should pay close attention to their websites. Just missing one update of the blogging software, forum script or database engine can be enough to give attackers the means to take over. Websites can be defaced or - which some webmasters consider even more seriously - manipulated in various ways. This includes links to other websites, malicious content that is served to visitors or changing the account ID of the Google Adsense account so that the hacker earns the money - or part of it - from that moment on.
All of this can have consequences for the webmasters. Search engines can punish websites who manipulate rankings, advertisers can kick webmasters and security software and scripts can flag a website to be malicious.
Unmask Parasites is one web based security script that can scan a website for hidden content that might be an indicator that the website was hacked or manipulated by someone else.
It works without registration. All the user needs to do is to enter a url in the search form and let the script do the rest. The script will display a ranking like "This page seems to be clean" listing all the external references - scripts and links - that it founds on that page.
Webmasters can follow those references and let the script analyze them as well or perform additional tests on the website. The two additional tests are the following:
These tests can aid the webmaster in spotting hidden malicious links in a timely manner. It is possible to bookmark the test page and open it again which will initiate a new scan of the website.
