Classe: Email-Worm
Email-Worms propagation par e-mail. Le ver envoie une copie de lui-même en pièce jointe à un message électronique ou un lien vers son fichier sur une ressource réseau (par exemple, une URL vers un fichier infecté sur un site Web compromis ou un site Web appartenant à un pirate). Dans le premier cas, le code du ver est activé lorsque la pièce jointe infectée est ouverte (lancée). Dans le second cas, le code est activé lorsque le lien vers le fichier infecté est ouvert. Dans les deux cas, le résultat est le même: le code du ver est activé. Email-Worms utilise une gamme de méthodes pour envoyer des emails infectés. Les plus courantes sont: l'utilisation d'une connexion directe à un serveur SMTP à l'aide du répertoire de messagerie intégré dans le code du ver en utilisant les services MS Outlook à l'aide des fonctions Windows MAPI. Email-Worms utilisent un certain nombre de sources différentes pour trouver les adresses email auxquelles les emails infectés seront envoyés: le carnet d'adresses dans MS Outlook une base de données d'adresses WAB .txt fichiers stockés sur le disque dur: le ver peut identifier les chaînes dans les fichiers texte Les e-mails adressent des e-mails dans la boîte de réception (certains e-mails peuvent même répondre aux e-mails trouvés dans la boîte de réception) De nombreux vers de messagerie utilisent plus d'une des sources répertoriées ci-dessus. Il existe également d'autres sources d'adresses électroniques, telles que les carnets d'adresses associés aux services de messagerie Web.Plus d'informations

Tactics and Techniques: Mitre*
TA0009
Collection
The adversary is trying to gather data of interest to their goal.
Collection consists of techniques adversaries may use to gather information and the sources information is collected from that are relevant to following through on the adversary's objectives. Frequently, the next goal after collecting data is to steal (exfiltrate) the data. Common target sources include various drive types, browsers, audio, video, and email. Common collection methods include capturing screenshots and keyboard input.

Screen Capture
Adversaries may attempt to take screen captures of the desktop to gather information over the course of an operation. Screen capturing functionality may be included as a feature of a remote access tool used in post-compromise operations. Taking a screenshot is also typically possible through native utilities or API calls, such as
CopyFromScreen, xwd, or screencapture.(Citation: CopyFromScreen .NET)(Citation: Antiquated Mac Malware)TA0011
Command and Control
The adversary is trying to communicate with compromised systems to control them.
Command and Control consists of techniques that adversaries may use to communicate with systems under their control within a victim network. Adversaries commonly attempt to mimic normal, expected traffic to avoid detection. There are many ways an adversary can establish command and control with various levels of stealth depending on the victim’s network structure and defenses.

Application Layer Protocol: Mail Protocols
Adversaries may communicate using application layer protocols associated with electronic mail delivery to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.
Protocols such as SMTP/S, POP3/S, and IMAP that carry electronic mail may be very common in environments. Packets produced from these protocols may have many fields and headers in which data can be concealed. Data could also be concealed within the email messages themselves. An adversary may abuse these protocols to communicate with systems under their control within a victim network while also mimicking normal, expected traffic.
