ACG-CYBER SECURITY BULLETIN NR 194: Beware of Pharma Hack
Reference Number ACG-CSB 082420194
The following information was obtained from different cyber security sources for notification to all parties concerned pursuant to the mandate of the Philippine National Police Anti-Cybercrime Group (PNP ACG) and classified as “Restricted” pursuant to the PNP Regulation 200-012 on Document Security and Impact Rating as high based on PNP Information Communication Technology (ICT) Security Manual s.2010-01 p. 22 and p.129.
The Pharma Hack is an exploit that takes advantage of vulnerabilities in WordPress or Joomla documents, causing search engines, notably the one hosted by Google, to return ads for pharmaceutical products along with legitimate listings. The hack can be difficult to detect because it does not affect the displayed pages of the compromised Web site or blog.
The purpose of the pharma hack is to make pharmaceutical sales sites they are promoting 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.
When a hacker has access to your site, they can change its contents. In a pharma hack, hackers redirect visitors to their own websites, insert spam links, change the title of your pages, and even add new pages. Hackers infect WordPress websites cleverly with minimal disturbance so that their dirty business goes undetected for as long as it possibly can.
Victims of the pharma hack have reported decreased traffic to their sites and, in some cases, removal of their sites by Google from search result lists. 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
All PNP personnel as well as the public are advised to follow the tips in order to avoid the risk of Pharma Hack to wit:
