Kategorie: Backdoor
Backdoors sollen bösartigen Benutzern die Fernsteuerung über einen infizierten Computer ermöglichen. In Bezug auf die Funktionalität ähneln Backdoors vielen Verwaltungssystemen, die von Softwareentwicklern entworfen und vertrieben werden.Diese Arten von bösartigen Programmen ermöglichen es, alles zu tun, was der Autor auf dem infizierten Computer möchte: Dateien senden und empfangen, Dateien starten oder löschen, Nachrichten anzeigen, Daten löschen, den Computer neu starten usw.
Die Programme in dieser Kategorie werden häufig verwendet, um eine Gruppe von Opfercomputern zu vereinigen und ein Botnet- oder Zombie-Netzwerk zu bilden. Dies gibt bösartigen Benutzern die zentrale Kontrolle über eine Armee von infizierten Computern, die dann für kriminelle Zwecke verwendet werden können.
Es gibt auch eine Gruppe von Backdoors, die sich über Netzwerke verbreiten und andere Computer infizieren können, wie Net-Worms es tun. Der Unterschied ist, dass sich solche Backdoors nicht automatisch verbreiten (wie Net-Worms), sondern nur auf einen speziellen "Befehl" von dem bösartigen Benutzer, der sie kontrolliert.

Tactics and Techniques: Mitre*
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.

Masquerading
Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation. This may include manipulating file metadata, tricking users into misidentifying the file type, and giving legitimate task or service names.
Renaming abusable system utilities to evade security monitoring is also a form of Masquerading.(Citation: LOLBAS Main Site) Masquerading may also include the use of Proxy or VPNs to disguise IP addresses, which can allow adversaries to blend in with normal network traffic and bypass conditional access policies or anti-abuse protections.

Masquerade File Type
Adversaries may masquerade malicious payloads as legitimate files through changes to the payload's formatting, including the file’s signature, extension, and contents. Various file types have a typical standard format, including how they are encoded and organized. For example, a file’s signature (also known as header or magic bytes) is the beginning bytes of a file and is often used to identify the file’s type. For example, the header of a JPEG file, is
0xFF 0xD8 and the file extension is either `.JPE`, `.JPEG` or `.JPG`. * © 2026 The MITRE Corporation. This work is reproduced and distributed with the permission of The MITRE Corporation.
