All of us knows that viruses harms our computer and every software development company is trying with all might to put a fix to all sorts of viruses. The big question here is, why would anyone create such harmful programs?
Most people especially the adolescents would write viruses out of mischief but there is also a section of virus writers who would create viruses for other bad intentions. But to make one understand this, first he or she must understand the “backdoor” concept.
Many companies, maybe an IT outsourcing company or a bank, keep their important information of their businesses in their system. There are people who pry on that and it is at such times that they use viruses to create vulnerabilities in their computers. The vulnerable part is called the backdoor through which attackers or hacker can gain control of the system(s).
A perfect example of a backdoor virus is the “Trojan Horse”. Trojan is a virus designed solely for opening backdoor. They are pieces of code you might download along with any file. It's name is taken from the Trojan war. However, (contradicting to my statement “Trojan is a virus”) Trojan is not considered a virus since Trojan doesn't replicate.
Once a hacker or an attacker gains control of a system, the main thing they do is get important information out and then send spams to other computers or emails connected to the computer under control. Spamming is done in order to gain control on other computers as well as to bring down the probability of tracking down the source of the virus.
This is all for the day. For more, visit back again.
