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

Defense Evasion
The adversary is trying to avoid being detected.
Defense Evasion consists of techniques that adversaries use to avoid detection throughout their compromise. Techniques used for defense evasion include uninstalling/disabling security software or obfuscating/encrypting data and scripts. Adversaries also leverage and abuse trusted processes to hide and masquerade their malware. Other tactics’ techniques are cross-listed here when those techniques include the added benefit of subverting defenses.

Hide Artifacts: Hidden Files and Directories
Adversaries may set files and directories to be hidden to evade detection mechanisms. To prevent normal users from accidentally changing special files on a system, most operating systems have the concept of a ‘hidden’ file. These files don’t show up when a user browses the file system with a GUI or when using normal commands on the command line. Users must explicitly ask to show the hidden files either via a series of Graphical User Interface (GUI) prompts or with command line switches (
On Linux and Mac, users can mark specific files as hidden simply by putting a “.” as the first character in the file or folder name (Citation: Sofacy Komplex Trojan) (Citation: Antiquated Mac Malware). Files and folders that start with a period, ‘.’, are by default hidden from being viewed in the Finder application and standard command-line utilities like “ls”. Users must specifically change settings to have these files viewable.
Files on macOS can also be marked with the UF_HIDDEN flag which prevents them from being seen in Finder.app, but still allows them to be seen in Terminal.app (Citation: WireLurker). On Windows, users can mark specific files as hidden by using the attrib.exe binary. Many applications create these hidden files and folders to store information so that it doesn’t clutter up the user’s workspace. For example, SSH utilities create a .ssh folder that’s hidden and contains the user’s known hosts and keys.
Adversaries can use this to their advantage to hide files and folders anywhere on the system and evading a typical user or system analysis that does not incorporate investigation of hidden files.

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.
