n the last few weeks, one of the most common infections that has been appearing on websites we have cleaned is hack for placing pharmaceutical adverts on sites.
The hack, is a type of malicious search engine ranking boosting technique that takes advantage of vulnerabilities in mostly (but not limited to) WordPress or Joomla websites. It’s goal is to make pharmaceutical sites appear higher in Google results than they otherwise would. The Google search engine ranks the list of hits for a given Web site according to (among other factors) the number of external sites that link to it. By inserting the rogue code into an unsuspecting victim’s site, the hack in effect links that site to the cracker’s site. If done on a large enough scale, this tactic can result in the cracker’s Web site showing up near the tops of various hit lists resulting from keyword-based searches.
Why Did It Take Me So Long To Know My Site Was Hacked ?
The hack can be difficult to detect because it does not affect the displayed pages of the compromised Web site or blog. So the spam (generally about Viagra, Cialis, etc) only shows up if the user is a search crawler (GoogleBot, etc) or the user is approaching the users site from a search result. Because of this behavior, many sites have been compromised for months with those spam keywords and the website owner is blissfully unaware. A quick way to check if your site is compromised is by searching on Google for “site:yourdomain.com cheap viagra”
Because Web site owners cannot readily see when they have been pharma hacked, the online reputation of a legitimate company or individual can be seriously damaged before the rogue code can be removed. Victims of this hack will have decreased traffic to their sites and, in some cases, removal of their sites by Google from search result lists.
How Do I Remove It From My Website ?
