MOREnet Security News Review -- January 20 - 24, 2014
CURRENT THREAT ACTIVITY REPORT
Over the last few weeks MOREnet Security has received numerous complaints for IP Addresses of devices on the MOREnet Network that are Open Recursive DNS Resolvers and are being used in Denial of Service attacks. Open Recursive DNS Resolvers provide recursive name resolution for clients outside of their organizations’ administrative domain. This provides attackers an easily exploitable attack vector to launch DoS or Amplification attacks against intended targets. One of the advantages of this type of attack is that it’s extremely hard to identify the source of the attack. As a best practice, MOREnet Security recommends that if you are running a DNS Server, review the configuration and determine if Open Recursion is necessary or if it can be disabled. NOTE: It would also be a good time to review all of the enabled services on the server. Other protocols can be exploited in similar manners. There are current news articles about recent attacks using Network Time Protocol (NTP). The following links provide additional information about the risks associated with Open Recursive DNS Resolvers and NTP and ways you can make them more secure. Don’t hesitate to contact us if you have questions or would like assistance verifying your configuration.
