Security Incident Caused and Outage

The Irish Google and Yahoo were taken offline on Tuesday this week when attackers managed to change DNS records according to reports.

It appears the hackers managed to change the sites’ Domain Name Server (DNS) records, according to the IE Domain Registry (IEDR). Currently the IEDRs’ site is offline.

The IEDR identified the two domains as and in a separate blog post, and identified the affected registrar as MarkMonitor.

IEDR and MarkMonitor found a solution to the issue, but it’s not clear how the unauthorized access happened. A possibility is that MarkMonitor’s login details for the IEDR registrar’s console was socially engineered.

The WHOIS records were changed to the following, with non google names servers.

Securing the country-level Domain Name System has been a topic discussion in the domain naming system community, MarkMonitor’s Smith said. “All TLDs should implement best practices security measures like those in use by Verisign over the .COM namespace, Neustar over .BIZ and Puerto Rico’s .PR namespaces. ”
