Thirty Computer Virus Programs example essay topic
The virus crashes or ruins the infected computer. A anti-virus company obtains a copy of the virus and studies it. The anti-virus company makes an "unbiased" decision about the virus and then disclose their findings to the public. The problem with the current system is that there are no checks and balances. If the anti-virus company wants to make viruses seem worse all they have to do is distort the truth. There is no organization that certifies whether or not a virus is real.
Even more potentially harmful is that the anti-virus companies could write viruses in order to sell their programs. Software companies have and do distort the truth about viruses. "Antivirus firms tend to count even the most insignificant variations of viruses for advertising purposes. When the Marijuana virus first appeared, for example, it contained the word "legalize", but a miscreant later modified it to read "legalize". Any program which detects the original virus can detect the version with one letter changed - but antivirus companies often count them as "two" viruses. These obscure differentiations quickly add up. web Incidentally the Marijuana virus is also called the "Stoned" virus there by making it yet another on the list of viruses that companies protect your computer against.
I went to the McAfee Anti-virus Web site looking for information on the Marijuana virus but was unable to obtain that information. I was however able to get a copy of the top ten viruses of their site. On specific virus called Junkie: "Junkie is a multi-partite, memory resident, encrypting virus. Junkie specifically targets. COM files, the DOS boot sector on floppy diskettes and the Master Boot Record (MBR). When initial infection is in the form of a file infecting virus, Junkie infects the MBR or floppy boot sector, disables V Safe (an anti-virus terminate-and-stay-resident program (TSR), which is included with MS-DOS 6.
X) and loads itself at Side 0, Cylinder 0, Sectors 4 and 5. The virus does not become memory resident, or infect files at this time. Later when the system is booted from the system hard disk, the Junkie virus becomes memory resident at the top of system memory below the 640 K DOS boundary, moving interrupt 12's returns. Once memory resident, Junkie begins infecting. COM files as they are executed, and corrupts. COM files.
The Junkie virus infects diskette boot sectors as they are accessed. The virus will write a copy of itself to the last track of the diskette, and then alter the boot sector to point to this code. On high density 5.25 inch diskettes, the viral code will be located on Cylinder 79, Side 1, Sectors 8 and 9". Junkie's description is that of a basic stealth / Trojan virus which have been in existance for 10 years. They also listed Anti-exe as one of the top ten viruses but did not acknowledge the fact that it has three aliases. It's no wonder that the general public is confused about computer viruses!
I decided to investigate the whole miss or diss-information issue a little further. I went to the Data Fellows Web site to what the distributors of F-prot had to say about viruses. It is to no surprise that I found them trying to see software with the typical scare tactics: Quite recently, we read in the newspapers how CIA and NSA (National Security Agency) managed to break into the EU Commission's systems and access confidential information about the GATT negotiations. The stolen information was then exploited in the negotiations.
The EU Commission denies the allegation, but that is a common practice in matters involving information security breaches. At the beginning of June, the news in Great Britain told the public about an incident where British and American banks had paid 400 million pounds in ransom to keep the criminals who had broken into their systems from publicizing the systems' weaknesses [London Times, 3.6. 1996]. The sums involved are simply enormous, especially since all these millions of pounds bought nothing more than silence.
According to London Times, the banks' representatives said that the money had been paid because "publicity about such attacks could damage consumer confidence in the security of their systems". Criminal hackers are probably encouraged by the fact that, in most cases, their victims are not at all eager to report the incidents to the police. And that is not all; assuming that the information reported by London Times is correct, they may even get paid a "fee" for breaking in a computer is broken into in Internet every 20 seconds Whatever the truth about these incidents may be, the fact remains that current information systems are quite vulnerable to penetration from outside. As Internet becomes more popular and spreads ever wider, criminals can break into an increasing number of systems easily and without a real risk of being caught". Then the next paragraph stated: "Even at their initial stages, Data Fellows Ltd's F-Secure products meet many of these demands. It is the goal of our continuing product development to eventually address all such information security needs".
In other words nothing is safe unless you buy their products. Now that we have cleared the smoke on viruses we know that there are only roughly 500 basic viruses. These viruses are tweaked, renamed, and re- cycled. So, what is a virus First of all, we must be aware that there is no universally accepted naming practice or discovery method for viruses. Therefore all virus information is subjective and subject to interpretation and constant dispute. To define a virus we must ask an expert.
According to Fred Cohen a computer virus is a computer program that can infect other computer programs by modifying them in such a way as to include a (possibly evolved) copy of itself. This does not mean that a virus has to cause damage because a virus may be written to gather data and obtain hidden files in your system. Now that you are aware of the hoaxes and miss-information about viruses you will be better equipped to deal with viral information. The next time you hear of a killer virus just remember what you have learned. You know that all viruses have the same roots.
