Класс: Trojan-PSW

Предназначены для кражи пользовательских аккаунтов (логин и пароль) с пораженных компьютеров. PSW – аббревиатура от Password Stealing Ware («ПО для кражи паролей»). При запуске PSW-троянцы ищут необходимую информацию в системных файлах, хранящих различную конфиденциальную информацию, или реестре. В случае успешного поиска программа отсылает найденные данные «хозяину». Для передачи данных могут быть использованы электронная почта, ftp, web (посредством указания данных в запросе) и другие способы. Некоторые троянцы данного типа воруют регистрационную информацию к различному программному обеспечению. Программы, занимающиеся кражей учетных записей пользователей систем интернет-банкинга, интернет-пейджинга и онлайн-игр, в силу их многочисленности, выделены в отдельные классы: Trojan Banker, Trojan IM и Trojan GameThief соответственно.

Privilege Escalation
The adversary is trying to gain higher-level permissions.

Privilege Escalation consists of techniques that adversaries use to gain higher-level permissions on a system or network. Adversaries can often enter and explore a network with unprivileged access but require elevated permissions to follow through on their objectives. Common approaches are to take advantage of system weaknesses, misconfigurations, and vulnerabilities. Examples of elevated access include:

* SYSTEM/root level
* local administrator
* user account with admin-like access
* user accounts with access to specific system or perform specific function

These techniques often overlap with Persistence techniques, as OS features that let an adversary persist can execute in an elevated context.

Access Token Manipulation
Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls. Windows uses access tokens to determine the ownership of a running process. A user can manipulate access tokens to make a running process appear as though it is the child of a different process or belongs to someone other than the user that started the process. When this occurs, the process also takes on the security context associated with the new token.

An adversary can use built-in Windows API functions to copy access tokens from existing processes; this is known as token stealing. These token can then be applied to an existing process (i.e. Token Impersonation/Theft) or used to spawn a new process (i.e. Create Process with Token). An adversary must already be in a privileged user context (i.e. administrator) to steal a token. However, adversaries commonly use token stealing to elevate their security context from the administrator level to the SYSTEM level. An adversary can then use a token to authenticate to a remote system as the account for that token if the account has appropriate permissions on the remote system.(Citation: Pentestlab Token Manipulation)

Any standard user can use the runas command, and the Windows API functions, to create impersonation tokens; it does not require access to an administrator account. There are also other mechanisms, such as Active Directory fields, that can be used to modify access tokens.
TA0005
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.
