WORM Wednesday
We hope you all got well informed from our Trojan-Tuesday post.
And now in Worm-Wednesday we will be discussing about one of the type of
malware that is known widely as "WORM".
Worms are computer malware programs that coded with the intention
of spreading from one computer system to another. They usually rely on networks
and security loopholes to spread from one computer to another computer. Worms
can be label as one man army because it does not need to attach itself with any
of the existing program.
One of its quality that makes it lethal is its self-replicating ability.
Worms replicate itself once it is inside a network or a system.
What harm
could that possibly cause??
Well, in case of network if the worm starts self-replicating
itself within a network then at some point of time it will start eating the
bandwidth of the network causing the network to slow down and eventually
connection losses.
Now, in case of computer the self-replicating quality of worm will
lead to consumption of system memory which will eventually slow system down and
eventually makes the system crash. Generally, most Worm are not intended to
cause harm to system they are passing through rather than other computer
malwares.
The first computer worm was the "Morris Worm" coded by
Robert Tappan Morris, a graduate student of Cornell University. It was launched
in 1988.The harm caused by Morris Worm was divesting. It caused a damage of
$100,000-10,000,000 (approx.).
Some of the other famous computer worms are as mentioned below:-
- ILOVEYOU
