Parent class: VirWare

Viruses and worms are malicious programs that self-replicate on computers or via computer networks without the user being aware; each subsequent copy of such malicious programs is also able to self-replicate. Malicious programs which spread via networks or infect remote machines when commanded to do so by the “owner” (e.g. Backdoors) or programs that create multiple copies that are unable to self-replicate are not part of the Viruses and Worms subclass. The main characteristic used to determine whether or not a program is classified as a separate behaviour within the Viruses and Worms subclass is how the program propagates (i.e. how the malicious program spreads copies of itself via local or network resources.) Most known worms are spread as files sent as email attachments, via a link to a web or FTP resource, via a link sent in an ICQ or IRC message, via P2P file sharing networks etc. Some worms spread as network packets; these directly penetrate the computer memory, and the worm code is then activated. Worms use the following techniques to penetrate remote computers and launch copies of themselves: social engineering (for example, an email message suggesting the user opens an attached file), exploiting network configuration errors (such as copying to a fully accessible disk), and exploiting loopholes in operating system and application security. Viruses can be divided in accordance with the method used to infect a computer:

• file viruses
• boot sector viruses
• macro viruses
• script viruses

Any program within this subclass can have additional Trojan functions. It should also be noted that many worms use more than one method in order to spread copies via networks.

Class: Virus

Viruses replicate on the resources of the local machine. Unlike worms, viruses do not use network services to propagate or penetrate other computers. A copy of a virus will reach remote computers only if the infected object is, for some reason unrelated to the virus function, activated on another computer. For example: when infecting accessible disks, a virus penetrates a file located on a network resource a virus copies itself to a removable storage device or infects a file on a removable device a user sends an email with an infected attachment.

Description

It is not a dangerous memory resident multipartite polymorphic and stealth virus. It infects COM, EXE files, the MBR of the hard drive and boot sector on floppy disks. When an infected file is executed, the virus infects the MBR and returns control to the host program. While loading from infected disk the virus hooks INT 13h, waits for DOS loading, then hooks INT 21h. By hooking INT 13h the virus infects floppy disk boot sector and run its stealth routine while accessing to the infected disks. By hooking INT 21h the virus also runs its stealth routine as well as affects DOS executable files that are accessed. The virus disables its stealth routines when PKZIP or BACKUP utilities are active. The virus also checks the file names and does not infect several anti-viruses and utilities according to the list:

Depending on the system date the virus runs some video effect. The virus contains the text strings:

Nuotando nel miele



Accecati dalla luce



Oppressi dalla liberta'



Nauseati dai falsi e facili sorrisi



Lottiamo per trovare qualcosa in cui credere.



Le note della rabbia e dell'instabilita'



sono il detonatore della voglia di proseguire...
