Kaspersky Threats — Trojan-PSW.MSIL.Agensla.adge

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.

Подробнее

Платформа: MSIL

MSIL (Microsoft Intermediate Language; новое название – CIL, Common Intermediate Language) – промежуточный язык, разработанный компанией Microsoft для платформы .NET Framework. Код на языке CIL генерируют все компиляторы .NET компании Microsoft, входящие в среду разработки Microsoft Visual Studio (Visual Basic .NET, Visual C++, Visual C# и другие).

Тактики и Техники: Mitre*

TA0004

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.

Process Injection

Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges. Process injection is a method of executing arbitrary code in the address space of a separate live process. Running code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via process injection may also evade detection from security products since the execution is masked under a legitimate process.

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.

Process Hollowing

Adversaries may inject malicious code into suspended and hollowed processes in order to evade process-based defenses. Process hollowing is a method of executing arbitrary code in the address space of a separate live process.

TA0006

Credential Access

The adversary is trying to steal account names and passwords. Credential Access consists of techniques for stealing credentials like account names and passwords. Techniques used to get credentials include keylogging or credential dumping. Using legitimate credentials can give adversaries access to systems, make them harder to detect, and provide the opportunity to create more accounts to help achieve their goals.

T1056.001

Keylogging

Adversaries may log user keystrokes to intercept credentials as the user types them. Keylogging is likely to be used to acquire credentials for new access opportunities when OS Credential Dumping efforts are not effective, and may require an adversary to intercept keystrokes on a system for a substantial period of time before credentials can be successfully captured. In order to increase the likelihood of capturing credentials quickly, an adversary may also perform actions such as clearing browser cookies to force users to reauthenticate to systems.

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.

T1071.001

Web Protocols

Adversaries may communicate using application layer protocols associated with web traffic 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.
