Classe: Backdoor
Les portes dérobées sont conçues pour permettre aux utilisateurs malveillants de contrôler à distance un ordinateur infecté. En termes de fonctionnalité, Backdoors sont similaires à de nombreux systèmes d'administration conçus et distribués par les développeurs de logiciels. Ces types de programmes malveillants permettent de faire tout ce que l'auteur veut sur l'ordinateur infecté: envoyer et recevoir des fichiers, lancer ou supprimer des fichiers, afficher des messages, supprimer des données, redémarrer l'ordinateur, etc. Les programmes de cette catégorie sont souvent utilisés afin d'unifier un groupe d'ordinateurs victimes et de former un réseau de zombies ou de zombies. Cela donne aux utilisateurs malveillants un contrôle centralisé sur une armée d'ordinateurs infectés qui peuvent ensuite être utilisés à des fins criminelles. Il y a aussi un groupe de Backdoors qui sont capables de se propager via des réseaux et d'infecter d'autres ordinateurs comme le fait Net-Worms. La différence est que ces portes dérobées ne se propagent pas automatiquement (comme le font les vers de terre), mais seulement sur une "commande" spéciale de l'utilisateur malveillant qui les contrôle.Plus d'informations

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.

System Network Configuration Discovery
Adversaries may look for details about the network configuration and settings, such as IP and/or MAC addresses, of systems they access or through information discovery of remote systems. Several operating system administration utilities exist that can be used to gather this information. Examples include Arp, ipconfig/ifconfig, nbtstat, and route.
Adversaries may also leverage a Network Device CLI on network devices to gather information about configurations and settings, such as IP addresses of configured interfaces and static/dynamic routes (e.g.
Adversaries may use the information from System Network Configuration Discovery during automated discovery to shape follow-on behaviors, including determining certain access within the target network and what actions to do next.

Remote System Discovery
Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for Lateral Movement from the current system. Functionality could exist within remote access tools to enable this, but utilities available on the operating system could also be used such as Ping or
Adversaries may also analyze data from local host files (ex:
Adversaries may also target discovery of network infrastructure as well as leverage Network Device CLI commands on network devices to gather detailed information about systems within a network (e.g.
net view using Net.Adversaries may also analyze data from local host files (ex:
C:\Windows\System32\Drivers\etc\hosts or /etc/hosts) or other passive means (such as local Arp cache entries) in order to discover the presence of remote systems in an environment.Adversaries may also target discovery of network infrastructure as well as leverage Network Device CLI commands on network devices to gather detailed information about systems within a network (e.g.
show cdp neighbors, show arp).(Citation: US-CERT-TA18-106A)(Citation: CISA AR21-126A FIVEHANDS May 2021) * © 2026 The MITRE Corporation. This work is reproduced and distributed with the permission of The MITRE Corporation.
