DNS remains a vital part of computer networking. However, it was never designed as a secure protocol and because of this it is a popular target for attackers. One of the more recent DNS attacks was the DNSChanger malware. It typically changes DNS server settings on infected computers, allowing attackers to route internet traffic through malicious servers and intercept sensitive information. There is also a similar variant targeting Apple Mac computers dubbed OSX/MaMi, an unsigned Mach-O 64-bit executable.

Read this blog post to find out more about how you can monitor DNS traffic and how you can have LANGuardian immediately alert, so you are notified if a client or server on your network uses an unauthorized DNS server.

And, as always, if you have questions about any aspect of LANGuardian or our Metadata instant alerting engine, please contact us on support@netfort.com any time.
