Technical Analysis by Steve Frield
W32.Dasher.D (12.19.2005) - a worm that exploits the following MS vulnerabilities: MS05-051 (on port 53/tcp) and MS04-045 (on port 42/tcp).
Listens for remote commands on port 53/tcp. Connects to an FTP server on port 21211/tcp. Scans for systems vulnerable to the MS05-051 exploit on port 1025/tcp. |

TCP ports use the Transmission Control Protocol. TCP is one of the main protocols in
TCP/IP networks. Whereas the IP protocol deals only with packets, 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.
Guaranteed communication is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol, a communications protocol for the Internet network,
transport, and session layers. Like TCP (Transmission Control Protocol),
UDP is used with IP (the Internet Protocol) and makes possible 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.
