Sınıf: Backdoor
Arka kapılar, kötü niyetli kullanıcıların virüslü bir bilgisayar üzerinde uzaktan denetimini sağlamak için tasarlanmıştır. İşlevsel açıdan, Backdoors, yazılım geliştiricileri tarafından tasarlanan ve dağıtılan birçok yönetim sistemine benzer. Bu tür kötü amaçlı programlar, yazarın virüslü bilgisayarda istediği herhangi bir şeyi yapmasını sağlar: dosya gönderme ve alma, dosyaları başlatma veya silme, mesajları görüntüleme, verileri silme, bilgisayarı yeniden başlatma vb. Bu kategorideki programlar sıklıkla kullanılır. Bir grup kurban bilgisayarını birleştirmek ve bir botnet veya zombi ağı oluşturmak için. Bu, kötü niyetli kullanıcılara, daha sonra, suçlu amaçlar için kullanılabilecek bir virüslü bilgisayar ordusu üzerinde merkezi kontrol sağlar. Ağlar üzerinden yayılabilen ve diğer bilgisayarları Net-Worms gibi etkileyebilen bir Back of grubu da var. Aradaki fark, bu Arka Planların otomatik olarak (Net-Solucanlar yaptığı gibi) yayılmamasıdır, ancak onları kontrol eden kötü niyetli kullanıcının özel bir “komutu” üzerinedir.Platform: Win32
Win32, 32-bit uygulamaların yürütülmesini destekleyen Windows NT tabanlı işletim sistemlerinde (Windows XP, Windows 7, vb.) Bir API'dir. Dünyanın en yaygın programlama platformlarından biri.Aile: Backdoor.Win32.Farfli

Tactics and Techniques: Mitre*
TA0002
Execution
The adversary is trying to run malicious code. Execution consists of techniques that result in adversary-controlled code running on a local or remote system. Techniques that run malicious code are often paired with techniques from all other tactics to achieve broader goals, like exploring a network or stealing data. For example, an adversary might use a remote access tool to run a PowerShell script that does Remote System Discovery.
T1059.001
PowerShell
Adversaries may abuse PowerShell commands and scripts for execution. PowerShell is a powerful interactive command-line interface and scripting environment included in the Windows operating system. Adversaries can use PowerShell to perform a number of actions, including discovery of information and execution of code. Examples include the
Start-Process cmdlet which can be used to run an executable and the Invoke-Command cmdlet which runs a command locally or on a remote computer (though administrator permissions are required to use PowerShell to connect to remote systems). T1059.005
Visual Basic
Adversaries may abuse Visual Basic (VB) for execution. VB is a programming language created by Microsoft with interoperability with many Windows technologies such as Component Object Model and the Native API through the Windows API. Although tagged as legacy with no planned future evolutions, VB is integrated and supported in the .NET Framework and cross-platform .NET Core.
T1106
Native API
Adversaries may interact with the native OS application programming interface (API) to execute behaviors. Native APIs provide a controlled means of calling low-level OS services within the kernel, such as those involving hardware/devices, memory, and processes. These native APIs are leveraged by the OS during system boot (when other system components are not yet initialized) as well as carrying out tasks and requests during routine operations.
TA0007
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.
T1010
Application Window Discovery
Adversaries may attempt to get a listing of open application windows. Window listings could convey information about how the system is used. For example, information about application windows could be used identify potential data to collect as well as identifying security tooling (Security Software Discovery) to evade.
T1120
Peripheral Device Discovery
Adversaries may attempt to gather information about attached peripheral devices and components connected to a computer system. Peripheral devices could include auxiliary resources that support a variety of functionalities such as keyboards, printers, cameras, smart card readers, or removable storage. The information may be used to enhance their awareness of the system and network environment or may be used for further actions.
