Context
The LNKR trojan is a malicious browser extension that will monitor the websites visited by the user, looking for pages with administrative privileges such as blog sites or web-based virtual learning environments. When the administrative user posts to the page, the infected extension will execute stored cross-site scripting attack and injects malicious JavaScript into the legitimate HTML of the page. This is used to redirect the second-party visitors of the site to both benign and malicious domains.
