CURRENT THREAT ACTIVITY REPORT

Over the last several weeks MOREnet Security has received numerous complaints for IP Addresses of devices on the MOREnet Network that are being used in Denial of Service attacks. The most recent complaints involve NTP. Network Time Protocol runs over UDP port 123 and is one of those “forgettable” protocols because it is typically configured once and then left alone. Unfortunately that means that upgrades aren’t performed on a regular basis which leaves it vulnerable to being used in an attack. NTP attacks are very similar to DNS amplification attacks. The attacker sends a small packet with a spoofed source IP requesting a large amount of data which is then sent to the Targeted Address. The NTP request is made using the monlist command. Monlist, a remote command available in older versions, sends the requestor (in an attack this will be the Target IP) a list of the last 600 hosts who have connected to that particular NTP server. The easiest way to secure NTP is to either disable the monlist functionality or update NTP to version 4.2.7 which by default does not enable the command. The following links provide additional information about the risks associated with NTP and things you can do to make it more secure. If you have questions or would like assistance, please don’t hesitate to call MOREnet Security.

KNOW YOUR ENEMY – THREAT ID OF THE WEEK

Forgotten or Unused Services – Sometimes we can end up being our own worst enemy… If you’re a system or network administrator, how often do you audit the services running on the devices you manage? Are they all necessary? Are they all patched? With the increase in attacks using older and/or often “forgotten” protocols, i.e. NTP-UDP port 123, DNS-UDP port 53, Chargen-UDP port 19, now would be a good time to take a look at your devices to make sure they’re running only what you need and the software is up-to-date.

FEATURED SERVICE

Good Net Neighbor Phase I  – In an effort to proactively reduce the number of security incidents caused by viruses and scanning, MOREnet offers a Good Net Neighbor Service to MOREnet customers. This is a low-risk, volunteer-based, no-cost service. Level One of the Good Net Neighbor Service will implement access control lists to block Windows Networking ports (TCP/UDP ports 135, 137, 138, 139 and 445). These ports are sometimes used by worms and viruses to scan, discover and infect other computers through the Internet. Check out the following link for more information on features, technical requirements, and support. http://www.more.net/services/good-net-neighbor-phase-1
