Classe: Net-Worm
Net-Worms se propagent via des réseaux informatiques. La caractéristique distinctive de ce type de ver est qu'il ne nécessite pas d'action de l'utilisateur pour se propager. Ce type de ver recherche généralement les vulnérabilités critiques des logiciels s'exécutant sur les ordinateurs en réseau. Afin d'infecter les ordinateurs sur le réseau, le ver envoie un paquet réseau spécialement conçu (appelé exploit) et par conséquent le code du ver (ou une partie du code du ver) pénètre dans l'ordinateur de la victime et l'active. Parfois, le paquet réseau contient uniquement la partie du code de ver qui va télécharger et exécuter un fichier contenant le module de ver principal. Certains vers de réseau utilisent simultanément plusieurs exploits pour se propager, augmentant ainsi la vitesse à laquelle ils trouvent des victimes.Plus d'informations

Tactics and Techniques: Mitre*
TA0002
Execution
The adversary is trying to run malicious code.
Execution consists of techniques that result in adversary-controlled code running on a local or remote system. Techniques that run malicious code are often paired with techniques from all other tactics to achieve broader goals, like exploring a network or stealing data. For example, an adversary might use a remote access tool to run a PowerShell script that does Remote System Discovery.

T1204.002
User Execution: Malicious File
An adversary may rely upon a user opening a malicious file in order to gain execution. Users may be subjected to social engineering to get them to open a file that will lead to code execution. This user action will typically be observed as follow-on behavior from Spearphishing Attachment. Adversaries may use several types of files that require a user to execute them, including .doc, .pdf, .xls, .rtf, .scr, .exe, .lnk, .pif, and .cpl.
Adversaries may employ various forms of Masquerading and Obfuscated Files or Information to increase the likelihood that a user will open and successfully execute a malicious file. These methods may include using a familiar naming convention and/or password protecting the file and supplying instructions to a user on how to open it.(Citation: Password Protected Word Docs)
While Malicious File frequently occurs shortly after Initial Access it may occur at other phases of an intrusion, such as when an adversary places a file in a shared directory or on a user's desktop hoping that a user will click on it. This activity may also be seen shortly after Internal Spearphishing.
