Класс: Virus
Вредоносная программа, обладающая способностью к несанкционированному пользователем саморазмножению по локальным ресурсам компьютера. В отличие от червей, вирусы не используют сетевых сервисов для своего распространения и проникновения на другие компьютеры. Копия вируса попадает на удалённые компьютеры только в том случае, если заражённый объект по каким-либо не зависящим от функционала вируса причинам оказывается активизированным на другом компьютере, например: при заражении доступных дисков вирус проник в файлы, расположенные на сетевом ресурсе; вирус скопировал себя на съёмный носитель или заразил файлы на нем; пользователь отослал электронное письмо с зараженным вложением.Подробнее

Persistence
The adversary is trying to maintain their foothold.
Persistence consists of techniques that adversaries use to keep access to systems across restarts, changed credentials, and other interruptions that could cut off their access. Techniques used for persistence include any access, action, or configuration changes that let them maintain their foothold on systems, such as replacing or hijacking legitimate code or adding startup code.

Account Manipulation
Adversaries may manipulate accounts to maintain and/or elevate access to victim systems. Account manipulation may consist of any action that preserves or modifies adversary access to a compromised account, such as modifying credentials or permission groups. These actions could also include account activity designed to subvert security policies, such as performing iterative password updates to bypass password duration policies and preserve the life of compromised credentials.
In order to create or manipulate accounts, the adversary must already have sufficient permissions on systems or the domain. However, account manipulation may also lead to privilege escalation where modifications grant access to additional roles, permissions, or higher-privileged Valid Accounts.

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.
T1036.007
Double File Extension
Adversaries may abuse a double extension in the filename as a means of masquerading the true file type. A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex:
File.txt.exe may render in some views as just File.txt). However, the second extension is the true file type that determines how the file is opened and executed. The real file extension may be hidden by the operating system in the file browser (ex: explorer.exe), as well as in any software configured using or similar to the system’s policies. * © 2026 The MITRE Corporation.
