Use our free Digital Footprint and Firewall Test to help verify you are not infected. Side note: UDP port uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT makes possible the transmission of a datagram message from one computer to an application running in another computer.
Because protocol UDP port was flagged as a virus colored red does not mean that a virus is using port , but that a Trojan or Virus has used this port in the past to communicate. We do our best to provide you with accurate information on PORT and work hard to keep our database up to date. This is a free service and accuracy is not guaranteed. We do our best to correct any errors and welcome feedback!
Your email address will not be published. Provides time synch between computers and network systems. Security Concerns: It provides both info and an avenue of attack for intruders. Further, if a host is susceptible to time altering via ntp, an attacker can: 1 Run replay attacks, using captured OTP and Kerberos tickets before they expire. There are a lot of portscans going on to every port on every IP on the internet as well, this could be completely unrelated to the ntp pool.
I investigated this a bit more and found that quite some of them are in fact ntpv4 client requests which are just not UDP but TCP for some unknown reason. The 0 length TCP syn packets get re-sent usually 2 or 3 times about 1 second apart from each other. How can it be NTP? Are there actually implementations out there which are so broken that they construct TCP queries and expect replies? I will evaluate this further since the second case seems to be more regional.
Can you give any examples of products which do 1 or references to seeing this traffic in the wild? Network time security is under study by IETF. Aside: packet analysis tools like Wireshark can use heuristics and may guess incorrectly. If there is a listener, the TCP connection payload can be analyzed.

Well Known Ports: 0 through Registered Ports: through TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent.
UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP the Internet Protocol and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. For more detailed and personalized help please use our forums.
