release date: July 12, 2019
The United Kingdom’s National Cyber Security Centre (NCSC) has released an
advisory about an ongoing Domain Name System (DNS) hijacking campaign. The
advisory details risks and mitigations for organizations to defend against this
campaign, in which attackers use compromised credentials to modify the location
to which an organization’s domain name resources resolve to redirect users,
obtain sensitive information, and cause man-in-the-middle attacks.
The Cybersecurity and Infrastructure Security Agency (CISA) encourages
administrators to review the NCSC
Advisory, apply the recommended mitigations, and refer to CISA’s Alert AA19-024A – DNS
Infrastructure Hijacking Campaign for more information.
