Definition - What does Proxy Hacking mean?
Proxy hacking is a technique used to attack authentic and original Web pages by replacing them with proxies or clones in an index of a search engine and in the results page. The usual motive of the assailant is to take advantage of their competitor’s site to make money on advertisements or place redirections such as links to direct the users viewing the site to malicious or deceitful phishing websites or websites that may contain viruses and Trojans.
Proxy hacking can also be refered to as proxy hijacking
Techopedia explains Proxy Hacking
In proxy hacking, the assailant makes a replica of the original Web page on a proxy server and uses different ways such as keyword stuffing and linking of the replicated site from other external sites to raise its search engine ranking even more than the original site. Because the replica ranks higher than the original site, search engines tend to remove the original site, seeing it as just a duplicate site.
Proxy hacking cannot be stopped entirely, but it can be minimized by limiting network connections from free and open proxy servers which are usually used for shady purposes.
