Classe: Trojan-Ransom
Ce type de cheval de Troie modifie les données sur l'ordinateur victime afin que la victime ne puisse plus utiliser les données ou empêche l'ordinateur de fonctionner correctement. Une fois que les données ont été "prises en otage" (bloquées ou cryptées), l'utilisateur recevra une demande de rançon. La demande de rançon indique à la victime d'envoyer de l'argent à l'utilisateur malveillant; à la réception de cela, le cyber-criminel enverra un programme à la victime pour restaurer les données ou restaurer les performances de l'ordinateur.Plus d'informations

TA0003
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.
T1547.014
Active Setup
Adversaries may achieve persistence by adding a Registry key to the Active Setup of the local machine. Active Setup is a Windows mechanism that is used to execute programs when a user logs in. The value stored in the Registry key will be executed after a user logs into the computer. These programs will be executed under the context of the user and will have the account's associated permissions level.
TA0004
Privilege Escalation
The adversary is trying to gain higher-level permissions. Privilege Escalation consists of techniques that adversaries use to gain higher-level permissions on a system or network. Adversaries can often enter and explore a network with unprivileged access but require elevated permissions to follow through on their objectives. Common approaches are to take advantage of system weaknesses, misconfigurations, and vulnerabilities. Examples of elevated access include: SYSTEM/root level, local administrator, user account with admin-like access, user accounts with access to specific system or perform specific function. These techniques often overlap with Persistence techniques, as OS features that let an adversary persist can execute in an elevated context.
