Hello Everybody! This is article again on techsoftcenter to discuss worms, some creepy worms in computers. In my previous post, I have already discussed the virus, top 10 hacks, iloveyou virus, and its source code.

What is a worm?

The worm is an animal which moves very slowly and this is according to science. In computers, the worm is something which makes the computer slow by replicating itself. Maximum worms won’t do any harm but they will replicate themselves and captures free space.

TCP or TCP/IP is the most used protocol on the internet. It is not only most used but also most secure. I have already explained to you what is TCP and how it works? In this article let’s discuss TCP 3 way handshake. It is also called 3 handshakes, TCP handshake but a handshake is common everywhere.

What is a 3-way handshake?

When any computer or net-enabled device tries to connect to any server or device to the port running on TCP then the connection will be established after three steps and so it is called TCP 3 way handshake.

Morris worm was created by a student from Cornell University named Robert Tappan Morris. It was created on November 2, 1988.

According to creator this worm was not created to damage but to find out the size of the internet. It worked by exploiting the vulnerabilities in Unix Sendmail, finger and many more. Later it was discovered that it has the power to crash the computer.

The link below shows how the Morris Worm is structured and where you can download code.

This post is about one of the greatest hacks all the time, ILOVEYOU virus aka love letter virus which affected 10 million computers and almost 10% percent of computers at the time of 2000.

Cheap History

On 5th May 2000, Reonel Ramones and Onel de Guzmen of Philippines created a virus name ILOVEYOU. It originated in Pandacan then spread across honking, Europe and then to US. This effected the loss around $20 billion.

Setting and management in Mikrotik Bandwidth cannot be separated from the Queue feature. There are two types of the queue which can be used in Mikrotik, namely Simple Queue and Queue Tree. For an explanation of Simple Queue I’ve discussed here:

How to Limit (Limit) Bandwidth Mikrotik with Simple Queue

Well, this time we will discuss the Company Queue Tree & PCQ (Per Connection Queue) as well as application in the Mikrotik.
