A huge DNS exploit could take down chunks of the internet

August 3, 2015 by Paul Spoerry Leave a Comment



Exploits start against flaw that could hamstring huge swaths of Internet
If you haven’t installed Bind update, now would be a good time to do so.

Last week the Internet Systems Consortium released a patch for a serious vulnerability in BIND, one of the most popular Domain Name Servers that’s bundled with Linux.

The incident number CVE-2015-5477 details an exploit that allows a remote, unauthenticated attacker to crash DNS servers using BIND by sending a specially crafted command. There’s no specific way to protect against the attack, other than installing the patch immediately.

The attack is reportedly so trivial that a single hacker could take down large chunks of the internet in a single move. All they would need to do is simultaneously crash enough DNS servers to cause a noticeable outage and serious implications for the internet.

Ars Technica reports today that attacks have already begun as the code is available publicly. The attack is now actively being used against public DNS servers to cause them to crash.

If you’re running a BIND DNS server, it’s important to patch as soon as possible to ensure attackers can’t take down your service.
