SEO poisoning: a danger for online users
SEO poisoning is a manipulation technique of search engines aimed at positioning malicious websites high in search engine results.
This practice exploits search engine optimization (SEO) techniques not to promote legitimate content but to drive users to harmful sites that could compromise their security.
The most common goal of SEO poisoning is to deceive users into accessing infected pages containing malware or attempting to steal personal and financial information.
What is SEO poisoning?
In an SEO poisoning attack, or search engine optimization poisoning, threat actors manipulate how search engines evaluate and rank websites to gain visibility in top search results.
The idea is to make a malicious site appear relevant and trustworthy to search engine algorithms by exploiting popular keywords and phrases searched by users.
This deceptive approach often combines keyword stuffing, unethical link-building, and creating networks of fake sites called private link networks.
Malicious actors aim to build content that mimics authentic sources to avoid detection as harmful. By inserting common keywords and building content related to trending searches, they increase the likelihood that users will encounter these dangerous pages.
How SEO poisoning works
SEO poisoning attacks work strategically and complexly. Malicious actors typically purchase registered domains with plausible names, making them visually similar to legitimate sites. They then optimize these sites using aggressive SEO techniques to get them to appear in search results.
Example
If a user searches for information on a medication, they might find a site that appears informative but actually hides malicious content ready to infect their device. To achieve this, threat actors leverage traditional content optimization methods, like keyword stuffing, to increase the relevance of their site for specific queries.
This tactic includes placing certain keywords unusually within articles, product pages, or reviews, boosting their chances of ranking highly on Google and other search engines.
Common goals of SEO poisoning
A primary goal of SEO poisoning is to spread malware and compromise users’ information. Often, these poisoning attacks are used to trick users into downloading malware or revealing sensitive information.
The most affected sectors are usually health, finance, and IT services, where the search for specific information makes users particularly vulnerable.
Threat actors target websites that attract high traffic volumes or specific queries related to trending topics, such as news about epidemics, investment advice, or searches for specific software.
People looking for this information are often inclined to click on the top results without much scrutiny, making them easy targets.
Techniques used in SEO poisoning and risks for users
SEO poisoning campaigns are organized to deceive both search engines and unsuspecting users.
They use tactics like creating networks of links between websites that link to each other to artificially increase the relevance of malicious sites.
This scheme is difficult for search engines to detect, as the links appear natural but are actually part of a single network managed by the same malicious actors.
Another commonly used technique is purchasing expired registered domains, which previously had an excellent reputation on search engines.
By reusing these domains and modifying the content, attackers can achieve high positions in search results.
How to detect and prevent SEO poisoning
To protect yourself from SEO poisoning, it’s essential to understand the techniques used by malicious actors and to use adequate protection tools.
Defense against these attacks starts with a solid knowledge of SEO practices and using tools to detect malicious content. Search engines, for their part, have begun to improve their algorithms to identify SEO poisoning patterns and remove malicious sites from results.
Businesses can adopt preventive measures to minimize risks. Some of these measures include:
- Using protective software that identifies potentially dangerous sites during browsing.
- Always checking the URL of sites to verify authenticity and avoiding links that seem suspicious.
- Implementing SEO monitoring tools to detect SEO poisoning and verify anomalies in search results related to their brand.
It’s also important to remember that search engines continuously evolve to counteract SEO poisoning tactics. However, prevention is the best defense to reduce the risk of exposure to harmful websites and protect your privacy and security.
