Linkedin DNS Hijack - Update
Update
It looks like this issue stemmed from a DDoS mitigation [1] gone awry or human error depending upon what source you refer to... [2]
Orginal
LinkedIn had its DNS "hijacked". There are no details right now, but often this is the result of an attacker compromissing the account used to manage DNS servers.But so far, no details are available so this could be just a simple misconfiguration.
The issue has been resolved, but If LinkedIn is "down" for you, or if it points to a different site, then you should flush your DNS cache.
It does not appear that Linkedin uses DNSSEC (which may not have helped if the registrar account was compromissed). Your best bet to make sure you connect to the correct site is SSL. But of course, "owning" the domain may allow the attacker to create a new certificate rather quickly.
As indicated in a comment below (and some twitter messages), other sites are affected as well. Please add a comment if you find any. The fact that multiple site's NS records are affected implies that this may not be a simple compromissed registrar account.
Current, appearantly accurate, DNS replies for LinkedIn:
dig +short A linkedin.com 216.52.242.86 dig +short NS linkedin.com ns4.p43.dynect.net. ns4.linkedin.com. ns3.p43.dynect.net. ns1.p43.dynect.net. ns2.p43.dynect.net. ns1.linkedin.com. ns3.linkedin.com. ns5.linkedin.com. ns6.linkedin.com. ns2.linkedin.com.

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
