Between March 29 and April 7 of 2014, the Turkish government announced a /32 BGP route for Google’s public DNS. This route redirected users to a DNS server which resolved popular addresses such as twitter.com and youtube.com to Turkish government websites. We previously wrote about this while it was happening. Now Stéphane Bortzmeyer’s talk, entitled “Google DNS Hijacking in Turkey” provides a technical understanding of how the Turkish Government accomplished this, and how he was able to prove it. His talk is now available for viewing from the RIPE 68 site. His slides are also available for viewing.
When you’re done watching the video, check out our resources on DNSSEC and how you can deploy it for zones your organization manages. While DNSSEC would not have prevented this hijack from occurring, it could have possibly detected this hijack for end users.
