Have you heard that the NCSC has warned about DNS hijacking threats focusing on home routers? These attacks aim to modify the settings on home routers, potentially via cross-site request forgery (CSRF) web-based attacks, so that they use rogue DNS servers. The end goal is to secretly redirect the user to a phishing page or one capable of installing malware on their machine.

The NCSC posted the advisory on Friday as a follow-up to one issued in January. DNS hijacking attackers typically take control of an authoritative DNS server, change the entries stored there and in so doing covertly redirect users to servers under their control, in a Man in the Middle attack.
