Mimikatz
Mimikatz ou Hacktool.Mimikatz n'est pas classé comme outil à haut risque bien qu'il puisse donner à un attaquant l'accès à une machine en corrompant des capacités déterminées dans un système d'exploitation Windows. Lorsqu'un ordinateur est attaqué par Mimikatz, ses contrôleurs peuvent injecter des DLL dans des processus aléatoires, exporter des certificats de sécurité, récupérer des mots de passe en texte brut à partir de Windows, désactiver certaines connexions et services de sécurité, effacer certains privilèges et échapper à quelques paramètres de stratégie de groupe.
Si vous pensez que Mimikatz peut avoir infecté votre ordinateur, il existe un moyen simple de le vérifier: utilisez un scanner dédié car il peut détecter et supprimer Mimikatz. Cependant, si vous n'êtes pas infecté par celui-ci et que vous souhaitez prendre des mesures pour éviter les infections, vous pouvez mettre en œuvre certaines stratégies, telles que vérifier la source et la fiabilité des e-mails provenant d'expéditeurs inconnus, être prudent lors du partage de fichiers, ne pas partager avec beaucoup d'informations sur les messageries instantanées, qui peuvent éviter d'innombrables problèmes, y compris été infecté par des menaces plus sévères.

Block Information
Block Information
During analysis, EnigmaSoft breaks file samples into logical blocks for classification and comparison with other samples. Blocks can be used to generate malware detection rules and to group file samples into families based on shared source code, functionality and other distinguishing attributes and characteristics. This section lists a summary of this block data, as well as its classification by EnigmaSoft. A visual representation of the block data is also displayed, where available.Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- MSIL.SharpKatz.B
