The Storm Worm (dubbed so by the Finnish company F-Secure) is a backdoor Trojan horse that affects computers using Microsoft operating systems, discovered on January 17, 2007. The worm is also known as Stuxnet is a malicious computer worm, first uncovered in 2010, thought to have been in development since at least 2005.Stuxnet targets supervisory control and data acquisition systems and is believed to be responsible for causing substantial damage to the nuclear program of Iran.Although neither country has openly admitted responsibility, the worm is widely understood to be a cyberweapon built. The worm was created by Robert Tappan Morris simply to see if it could be done. The worm was released from MIT in the hope of suggesting that its creator studied there instead of Cornell, (though Morris became a tenured professor at MIT in 2006). It worked by exploiting known vulnerabilities in Unix sendmail, finger, and rsh/rexec, as well as weak passwords ILOVEYOU, sometimes referred to as Love Bug or Love Letter for you or the fake love letter, is a computer worm that infected over ten million Windows personal computers on and after 4 May 2000 when it started spreading as an email message with the subject line ILOVEYOU and the attachment LOVE-LETTER-FOR-YOU.txt.vbs.

A computer worm is a kind of malware that is able to copy itself, and spread. Unlike a computer virus, this is done without changing files on a computer, and without affecting the boot sector of media. Worms do not need human help to reproduce. Worms spread over networks, or on removable media like USB flash drives

Sasser is a computer worm that affects computers running vulnerable versions of the Microsoft operating systems Windows XP and Windows 2000. Sasser spreads by exploiting the system through a vulnerable port. Thus it is particularly virulent in that it can spread without user intervention, but it is also easily stopped by a properly configured firewall or by downloading system updates from Windows Update. The specific hole Sasser exploits is documented by Microsoft in its MS04-011. WORM (en.

A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be infected with a computer virus.

Stuxnet är det första bekräftade exemplet på ett fysiskt sabotage via datorprogram. Programmet innehåller många olika komponenter - alla mycket avancerade - bland annat för att sprida programmet, för att bryta sig igenom säkerhetsskydd, för att kommunicera med kommandocentraler, för att utföra det fysiska sabotaget och för att dölja angreppet Worms är en stad i den tyska delstaten Rheinland-Pfalz i sydvästra Tyskland med 82 102 invånare (2015).

A worm virus establishes itself in a host system and stays active on a newly infected computer, the malware then starts a network search for possible new storage devices to infect Through this way the worm is able to multiply and spread its infection to all interconnected devices in a network Key Difference Between Virus And Worms. Worms use Computer Networks to spread itself while Viruses spread to different systems through executable files. Spreading speed of a Worm is faster than a Virus. The virus tends to damage, destroy or alter the files of target computers, whereas, Worms does not modify any file but aims to harm the resources

A computer worm is a type of malware that spreads copies of itself from computer to computer. It can replicate itself without any human interaction and does not need to attach itself to a software program in order to cause damage. Worms can be transmitted via software vulnerabilities The worm then spreads across the network, scanning for Siemens Step7 software on computers controlling a PLC. If it doesn't find a target, Stuxnet becomes dormant inside the computer. Stuxnet is special for different reasons: It used flaws of the operating system Microsoft Windows which were not known to many people at the time Blaster (även känd som MSBlast och Lovsan) var en internetmask som spreds till datorer som körde Microsofts operativsystem Windows XP och Windows 2000 under augusti 2003..

  1. To be classified as a virus or worm, malware must have the ability to propagate. The difference is that a worm operates more or less independently of other files, whereas a virus depends on a host program to spread itself. These and other classes of malicious software are described below
  2. How To: Remove a worm virus from your computer. Internet worms are the most common type of virus infecting computers today. Internet worms spread across networks using email, Internet chat, peer-to-peer (P2P) file sharing networks and other methods
  3. Once a virus finds its way onto your system, it will remain dormant until the infected host file or program is activated, which in turn makes the virus active enabling it to run and replicate on your system. Worms, on the other hand, don't need a host program in order for them to run, self-replicate and propagate
  4. A computer virus is a program that is able to copy itself when it is run. Often, computer viruses are run as a part of other programs. Any program that is affected by the virus is infected. Biological viruses also work that way, as they copy themselves as part of other organisms.This is how the computer virus got its name

How it worked. The SQL worm mainly attacked computers that had Microsoft SQL Server 2000 or Microsoft Desktop Engine 2000 on them.
