Класс: Email-Worm
Размножаются по каналам электронной почты. При этом червь отсылает свою копию в виде вложения в электронное письмо или ссылку на свой файл, расположенный на каком-либо сетевом ресурсе (например, ссылку (URL) на зараженный файл, расположенный на взломанном или хакерском веб-сайте). В первом случае код червя активизируется при открытии (запуске) зараженного вложения, во втором — при открытии ссылки на зараженный файл. В обоих случаях результат одинаков — активизируется код червя. Для отправки зараженных сообщений почтовые черви используют различные способы. Наиболее распространены: • прямое подключение к SMTP-серверу, с использованием встроенной в код червя почтовой библиотеки; • использование сервисов MS Outlook; • использование функций Windows MAPI. Почтовые черви используют различные источники для поиска почтовых адресов, на которые будут рассылаться зараженные письма: • адресная книга MS Outlook; • адресная база WAB; • файлы текстового формата на жестком диске: выделяют в них строки, являющиеся адресами электронной почты; • письма, которые находятся в почтовом ящике (при этом некоторые почтовые черви «отвечают» на обнаруженные в ящике письма). Многие почтовые черви используют сразу несколько из перечисленных источников. Бывают и другие источники адресов электронной почты, например адресные книги почтовых сервисов с web-интерфейсом.Подробнее

Discovery
The adversary is trying to figure out your environment.
Discovery consists of techniques an adversary may use to gain knowledge about the system and internal network. These techniques help adversaries observe the environment and orient themselves before deciding how to act. They also allow adversaries to explore what they can control and what’s around their entry point in order to discover how it could benefit their current objective. Native operating system tools are often used toward this post-compromise information-gathering objective.

Remote System Discovery
Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for Lateral Movement from the current system. Functionality could exist within remote access tools to enable this, but utilities available on the operating system could also be used such as Ping or
Adversaries may also analyze data from local host files (ex:
Adversaries may also target discovery of network infrastructure as well as leverage Network Device CLI commands on network devices to gather detailed information about systems within a network (e.g.
net view using Net.Adversaries may also analyze data from local host files (ex:
C:\Windows\System32\Drivers\etc\hosts or /etc/hosts) or other passive means (such as local Arp cache entries) in order to discover the presence of remote systems in an environment.Adversaries may also target discovery of network infrastructure as well as leverage Network Device CLI commands on network devices to gather detailed information about systems within a network (e.g.
show cdp neighbors, show arp).(Citation: US-CERT-TA18-106A)(Citation: CISA AR21-126A FIVEHANDS May 2021) 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.
