Baidu announced recently that it’s upgrading its Beacon-Fire algorithm to fight hyperjacking – Beacon-Fire 1.0 and Beacon-Fire 2.0 were released on Feb 2017 and May 2018 respectively.
Baidu claimed that hyperjacking is “extremely harmful” to search engine users and listed two forms of hyperjacking: jump hijacking and back hijacking.
In either case, visitors would be redirected to a false Baidu search result page or a page filled with ads or even viruses.
