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.Poison

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.

Exploitation for Client Execution
Adversaries may exploit software vulnerabilities in client applications to execute code. Vulnerabilities can exist in software due to unsecure coding practices that can lead to unanticipated behavior. Adversaries can take advantage of certain vulnerabilities through targeted exploitation for the purpose of arbitrary code execution. Oftentimes the most valuable exploits to an offensive toolkit are those that can be used to obtain code execution on a remote system because they can be used to gain access to that system. Users will expect to see files related to the applications they commonly used to do work, so they are a useful target for exploit research and development because of their high utility.
Several types exist:
### Browser-based Exploitation
Web browsers are a common target through Drive-by Compromise and Spearphishing Link. Endpoint systems may be compromised through normal web browsing or from certain users being targeted by links in spearphishing emails to adversary controlled sites used to exploit the web browser. These often do not require an action by the user for the exploit to be executed.
### Office Applications
Common office and productivity applications such as Microsoft Office are also targeted through Phishing. Malicious files will be transmitted directly as attachments or through links to download them. These require the user to open the document or file for the exploit to run.
### Common Third-party Applications
Other applications that are commonly seen or are part of the software deployed in a target network may also be used for exploitation. Applications such as Adobe Reader and Flash, which are common in enterprise environments, have been routinely targeted by adversaries attempting to gain access to systems. Depending on the software and nature of the vulnerability, some may be exploited in the browser or require the user to open a file. For instance, some Flash exploits have been delivered as objects within Microsoft Office documents.

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.

T1070.004
Indicator Removal: File Deletion
Adversaries may delete files left behind by the actions of their intrusion activity. Malware, tools, or other non-native files dropped or created on a system by an adversary (ex: Ingress Tool Transfer) may leave traces to indicate to what was done within a network and how. Removal of these files can occur during an intrusion, or as part of a post-intrusion process to minimize the adversary's footprint.
There are tools available from the host operating system to perform cleanup, but adversaries may use other tools as well.(Citation: Microsoft SDelete July 2016) Examples of built-in Command and Scripting Interpreter functions include
