In the mid-1990s, as people started flocking to the Internet and websites began appearing left and right, there came a need for a more systematic way to search for information, leading to the birth of search engine optimization (SEO). Today, in addition to making it easier for users to look for information online, SEO is also used for driving traffic to websites, increasing website usability, and for marketing purposes, among other things. SEO was introduced in order to make users’ online experience more enjoyable. But some people are taking advantage of what it can do to advance their malicious interests. Filling seemingly legitimate websites and search results with infected links, this malicious SEO practice, called SEO poisoning, is not just crippling, but also dangerous.
SEO poisoning in a nutshell
In SEO poisoning, cybercriminals use social engineering to create malicious websites filled with malware, making these websites appear authentic to fool unwitting users. They then use SEO to populate search results with links leading to these sites. To get more victims, the creators take advantage of the high search volume associated with trending topics and currently popular websites when creating spoof websites.
Another attack method used in SEO poisoning is by infecting the links within an authentic website such as images and headers. Victims who unknowingly click an infected website link are then transferred to a malicious site where they become exposed to a number of threats including Trojan files and bots, just by browsing through the infected website.
Once a device has been breached, hackers will be able to do their bidding: access personal information such as credit card transactions, prevent users from accessing their files and demand a ransom for the decryption key, steal identities, and turn a device into a component of their botnet, etc.
