Worms and Trojan Horses
A worm is a program than can make copies of itself from one disk drive to another. It is self contained and can also spread by copying itself using email or another form of transport. Worms can compromise the security systems of computers and can cause damage in the process. Worms sent via email usually comes in the form of a joke program or some type of software. They can cause thousands of dollars in damages. A worm would be a weapon of choice for an electronic attack that could cause widespread economic damage by disrupting and or destroying a large fraction of computers responsible for day to day business said Nicholas Weaver and Vern Paxson, two security researchers who worked on a project “Worst-Case Worm Attacks,” in collaboration with the International Computer Science Institute (ICSI) a non profit research group associated with the University of California at Berkley in 2004.
Trojan horses are programs known to have benign capabilities. It neither replicates nor copies itself, but can cause damage and or compromise the security system of a computer. Trojan horses are usually sent by individuals in the forms of email. Like the worm it is usually in the form of a joke or a software program. Some tasks that are performed by Trojan worms includes opening an internet connection that allows an outsider to gain access to information and files on the user’s computer without the user’s knowledge. Looking for passwords or confidential information stored on the computer and emailing them o the attackers address.
In life many make decisions without thinking of the repercussions. Morally it is wrong to release a worm regardless of the fact that it may be harmless or not. It may not necessarily crash a system but may slow it down for a day or two causing delays and draw backs to the many that it affects. What started out as an experiment in the head of Morris to show the glitches in Uniex operating system, turned out to be a national disaster. Based on

In a similar way to junk mail coming in your door at home, email users regularly receive unsolicited emails from unknown senders.

    A Trojan Horse is full of as much trickery as the mythological Trojan Horse it was named after. The Trojan Horse, at first glance will appear to be useful software but will actually do damage once installed or run on your computer. Those on the receiving end of a Trojan Horse are usually tricked into opening them because they appear to be receiving legitimate software or files from a legitimate source. When a Trojan is activated on your computer, the results can vary. Some Trojans are designed to be more annoying than malicious (like changing your desktop, adding silly active desktop icons) or they can cause serious damage by deleting files and destroying information on your system. Trojans are also known to create a backdoor on your computer that gives malicious users access to your system, possibly allowing confidential or personal information to be compromised. Unlike viruses and worms, Trojans do not reproduce by infecting other files nor do they self-replicate.…
