The World's Most Dangerous Virus

The World's Most Dangerous Virus: by Michael Robertson

Imagine if a computer virus emerged that secretly attached itself to one of the most popular software programs ever. Imagine if the largest media outlets unwittingly praised this secret pairing, encouraging millions of people to install it. Imagine if none of the major antivirus programs would detect it. Imagine if once installed, it could alter anything on your computer without your consent or knowledge. Imagine if the virus was at the control of a greedy entity that has repeatedly trampled on consumers and smaller companies to advance its corporate agenda. Imagine if it could force everyone who wanted to communicate with you to also carry the virus so it would insidiously spread person to person. Sound like a scary sci-fi plot? It's not science fiction. This week MO3 will be released on the world. Here's how to detect it in your neighborhood and what you can do to protect yourself

The Trojan Horse

Press outlets will blanket the world with stories about Microsoft Office 2003. Most articles will tout seemingly innocuous features and feel good quotes from Microsoft like "this is our most important product release ever." Unfortunately the press won't talk about the dangerous software buried inside this release - MO3. This code will give Microsoft the ability to change anything on your computer at anytime they wish with no notification to you.

The Security Ploy

Post 9/11, few people question actions taken under the guise of "improved security" and this is how MO3 will be foisted onto computer users - as a feature to 'make you safer.' Computer users have understandably tired of the near daily worm and virus warnings, as well as the time-consuming patch process due to Microsoft's lax software standards and its focusing not on building secure products, but products that secure its monopoly market positions. To improve the predicament which they've created, Microsoft is forcing consumers to accept MO3 embedded into every computer. Listen closely and you'll hear Microsoft mouth pieces speak of "turning software into a service" which really means they will be changing the software on your computer whenever they feel like it. They will slowly limit your ability to run non-Microsoft software. They will restrict choices on your computer to only those products they approve. They will make changes which cripple other software programs or reduce their ability to interoperate with your computer so you will be forced to use exclusively Microsoft approved products.

History Repeats Itself

Microsoft may use this newfound power to fix some holes in their software, but they will also abuse this power to further their corporate monopoly and increase their control and profits. Microsoft has already embedded the MO3 virus into another operating system they have deployed, called Xbox. They now have the power at anytime to change all existing Xboxes which connect to the Internet, and they are already misusing it. They have deleted files from users' computers without their knowledge or permission. They have added software which has removed the ability to run competitor's software. They have been changing users' systems without their consent and notification. They will do the same on Microsoft Windows based computers once MO3 is installed.

Microsoft management has shown to be deceitful and dishonest and will continue this behavior. Twice Microsoft has been found guilty by the Federal government of using illegal tactics to drive competitors out of business and extend their monopoly. December 1st, 2003 a trial will take place in Seattle Washington where more of Microsoft's past behaviors will come to light.

Infecting Friends

Microsoft Word (.doc) file open in StarOffice 7

To stop the advance of competing products and to force users into purchasing new software with the MO3 virus, Microsoft is making certain Microsoft Office 2003 files unreadable by all older versions of Microsoft Office and all competing office suites. Products like Sun's StarOffice are getting extremely good at interoperating with Microsoft word processing, presentation and spreadsheet files making it possible for people to spend close to $50 for an office suite instead of giving $400 or more to Microsoft. To blunt this and force users of older versions of Microsoft Office to buy new software, Microsoft has changed the specifications for some files.

Again under the umbrella of "security," Microsoft is implementing features which limit who can open and edit documents to further thwart competition. Microsoft Office 2003 gives its users the ability to control who can read and edit certain documents, but only if they use the latest Microsoft software. If one user within an office uses this feature, all others will be unable to use any other office suite to access that document. They will not be permitted to run Linux software, they will be required to purchase and run additional copies of Microsoft Office 2003. Since documents are frequently emailed around via the Internet, this will force others to accept Microsoft's software or be unable to communicate. Microsoft refers to this as IRM for "information rights management," but it's really an "infection relay method" designed to force everyone to adopt MO3. They will be using scare tactics about leaked memos or misdirected emails to persuade unwitting computer users to deploy this technology. Doing so will create a viral growth of MO3 which will give MS unlimited power over every computer.

Universal MO3

MO3 will not only come with Microsoft Office 2003, but with future Microsoft products as well. The same technology will be embedded into the next version of Microsoft's operating system software so all users will have to accept it with their new computer. Latest estimates indicate this new software will not ship until 2006, so between now and then, watch for Microsoft to secretly embed MO3 into updates or security patches that they promote for their existing product line.

Protect Yourself

Microsoft Excel (.xls) file open in StarOffice 7

There are precautionary measures you can take to fend off MO3. First off, do not purchase and install Microsoft Office 2003. Also, discourage those around you from purchasing Microsoft Office as well, since one infection will quickly grow. If you need a new office suite, check out the solid and affordable StarOffice 7.0 which runs equally well on Microsoft Windows or Linux computers, and can be purchased online and immediately downloaded and installed. Encourage those penning articles and reviews to fully inform their readers of the dangers of Microsoft Office 2003. Finally, encourage them to do in-depth reviews of Microsoft Office 2003 vs. Sun's StarOffice 7.0 so people can make informed decisions about the benefits and risks of either product.

The Most Dangerous Computer Viruses in History

Computer viruses have a relatively short history by the damages caused by some of the most dangerous viruses pushed cyber-experts to open a chapter that includes a huge database on computer viruses and the cost of damages caused along with companies, government and universities highly affected by malware.

Here are some of the most dangerous computer viruses in history:

Jerusalem - 1988

This is one of the first MS-DOS viruses in history that caused enormous destructions, affecting many countries, universities and company worldwide. On Friday 13, 1988 the computer virus managed to infect a number of institutions in Europe, America and the Middle East. The name was given to the virus after one of the first places that got "acquainted" with it - the Jerusalem University.

Along with a number of other computer viruses, including "Cascade", "Stoned", "Vienna" the Jerusalem virus managed to infect thousands of computers while still remaining unnoticed. Back then the anti-virus programs were not as advanced as they are today and a lot of users had little belief of the existence of computer viruses.

Morris (a.k.a. Internet Worm) - November 1988

This computer virus infected over 6,000 computer systems in the United States, including the famousNASA research Institute, which for some time remained completely paralyzed. Due to erratic code, the worm managed to send millions of copies of itself to different network computers, being able to entirely paralyze all network resources. The damages caused by the Morris computer virus were estimated at $96 millions.

To be able to spread the computer virus used errors in such operating systems as Unix for VAX and Sun Microsystems. There were a number of other interesting ideas used by the virus - for example it could pick user passwords.

Solar Sunrise - 1998

A decade later the situation didn't change, it might have gotten even got worse. Using a computer virus, hackers, in 1998, penetrated and took control of over 500 computers systems that belonged to the army, government and private sector of the United States. The whole situation was dubbed Solar Sunrise after the popular vulnerabilities in computers that run on the operating system called Sun Solaris. Initially it was believed that the attacks were planed by the operatives in Iraq. It was later revealed that the incidents represented the work of two American teenagers from California. After the attacks, the Defense Department took drastic actions to prevent future incidents of this kind.

Melissa - 1999

For the first time computers got acknowledged with Melissa computer virus on March 26, 1999, when the virus shut down Internet mail system, which got blocked with e-mails infected by the worm. It is worth mentioning that at first Melissa was not meant to cause any harm, but after it overloaded servers the virus led to unpredictable problems. For the first time it spread in the Usenet discussion group alt.sex. Melissa was hidden within a file called "List.DiC", which featured passwords that served as keys to unlocking 80 pornographic websites. The original form of the virus was sent through e-mail to different users.

Melissa computer virus was developed by David L. Smith in Aberdeen Township, New Jersey. Its name comes from a lap dancer that the programmer got acknowledged with while in Florida. After being caught, the creator of the virus was sentenced to 20 months in federal prison and ordered to pay a fine of $5,000. The arrest represented a collaboration of FBI, New Jersey State Police and Monmouth Internet.

Melissa had the ability to multiply on Microsoft Word 97 and Word 2000, as well as Microsoft Excel 97, 2000 and 2003. In addition, the virus had the ability to mass-mail itself from Microsoft Outlook 97 or Outlook 98.

I Love You - May 2000

Using a similar method as the Melissa, the computer virus dubbed "I Love You" managed to infect millions of computers around the world in just one night. Just like Melissa this computer virus sent passwords and usernames, which were stored on the attacked computers, back to the developer of the virus. After authorities traced the virus they found that a young Filipino student was behind the attack. The young man was released due to the fact that the Philippines did not have any law that would prevent hacking and spreading malware. This situation served as one of the premises for creating theEuropean Union's global Cybercrime Treaty.

The Code Red worm - July 2001

This 21st century computer virus managed to penetrate tens of thousands of systems that ran Microsoft Windows NT as well as Windows 2000 server software. The damages caused by the Code Red computer virus were estimated at a total of $2 billion. Core Red was developed to use the power of all computers it infected against the official website of the White House at a predetermined date. In collaboration with different virus hunters and tech firms, the White House managed to decipher the code of the Code Red virus and stop traffic as the malware started its attacks.

Nimda - 2001

Shortly after the September 11 tragedy this computer virus infected hundreds of thousands of computers worldwide. Nimda was considered to be one of the most complicated viruses, having up to 5 different methods of infecting computers systems and duplicating itself.

Downadup - 2009

The latest and most dangerous virus is the "downadup" worm, which was also called "Conficker". The computer security company F-Secure stated that the computer virus has infected 3.5 million computers worldwide. This malicious program was able to spread using a patched Windows flaw. Downadup was successful in spreading across the Web due to the fact that it used a flaw that Microsoft patched in October in order to distantly compromise computers that ran unpatched versions of Microsoft's operating system. But the greatest power of the worm is believed to be the ability of computers, infected with the worm, to download destructive code from a random drop point. F-Secure stated that three of the most affected countries were China, Brazil and Russia.

6 ever Most Dangerous Computer pc viruses and worms

Viruses and worms are a cause for thousands of losses all over the world. There are number of viruses and worms created. Below i have listed 6 most dangerous and havoc creating viruses that affected millions of computer users over the world. The order of viruses is not important.

Most dangerous computer viruses :

1. ILOVEYOU :

This ILOVEYOU worm is considered to be most dangerous worm ever created. It was written in VBScript. It was first noticed in Philippines on May 4 2000 and then spread all over world in just one day, affecting 10% internet users and causing loss of about $5.5 billion. The worm arrived in email inbox with subject “ILOVEYOU”. Hence, called ILOVEYOU worm. It had an attachment “LOVE-LETTER-FOR-YOU.TXT.vbs” . The worm overwrote many important files, with music, multimedia files with a copy of itself attached to each file. Also, it sent the worm to everyone on victim contact list. Thus, worm spread very fast. Only windows users were affected.

2. Mydoom :

Mydoom , a computer virus affected Microsoft Windows. After it was first noticed on January 26, 2004, it became fastest spreading computer virus ever, breaking record of Sobig worm. Mydoom was designed to send junk emails from infected computers. The actual worm programmer is still unknown.

3. Virut virus :

This Virut virus infects executable portable files such as .exe and .scr andeach time it propagates it uses Polymorphism - to evade detection. On infected machine, virus opens a backdoor connecting with an IRC server which is prespecified by virus programmer. This backdoor allow attacker to download additional malware to victim computer. This virus affected and shut down court system computers of Texas this February.

4. Blaster worm :

This Blaster worm - a computer worm that affected computers running Microsoft operating systems. But, the spread of this worm was limited by filtering of ISP and its publicity. The worm was designed to start a SYN Flood on Aug 15, 2003 against port 80 of windowsupdate.com, intended to create a distributed DDoS attack against this site.

If the worm detects an internet connection, the system would become unstable and after displaying a message for 60 seconds, the system used to restart. The message displayed looked like:

“I just want to say LOVE YOU SAN!!”

“billy gates why do you make this possible? Stop making money

and fix your software!!”

5. Sobig worm :

This worm ws detected in Aug 2003 which affected millions of internet connected windows operating systems. The worm was written using Microsoft Visual C++ compiler and compressed using tElock. The most destructive version was Sobig.F .

This worm was worm as it replicated itself and also a Trojan Horse as it appeared other than malware. The programmer of this worm is still not known.

6. Conficker virus :

This virus came into role in November 2008 and affected millions of computer. Basically, its a worm capable of replicating itself and thus can spread fast. The worm spreads itself primarily through a buffer overflow vulnerability in the Server Service on Windows based computers.

When this worm is executed on a computer, it is capable of disabling Windows services such as Windows Update, Windows Defender, Windows Security Center and even Windows Error reporting.

But, the threat due to this worm is reduced as most antiviruses are now detecting this worm and its further spread is thus prevented. This worm is mainly spreading in China, followed by Argentina, Brazil, Russia, and India - where software update is done to less extent.

So friends, this is all about viruses. These are most dangerous viruses or worms that affected millions of worldwide computers. I just wanted to say that keep your antiviruses updated to prevent yourself from being affected by such viruses and worms. If you think any other virus or worm needs mention over here, please mention it in comments section. I will update the article.

Enjoy…..
