Selon des sources en ligne, des milliers d'ordinateurs fonctionnant sous Windows ont \u00e9t\u00e9 infect\u00e9s par un nouveau type de logiciel malveillant qui t\u00e9l\u00e9charge et installe une copie de l'infrastructure Node.js, transformant les syst\u00e8mes infect\u00e9s en serveurs proxy utilis\u00e9s pour mener des op\u00e9rations frauduleuses.<\/p>\n

\"Le<\/p>\n

Les programmes malveillants, appel\u00e9s Nodersok dans le rapport de Microsoft et Divergent dans le rapport de Cisco Talos, ont \u00e9t\u00e9 d\u00e9couverts cet \u00e9t\u00e9. Ils ont \u00e9t\u00e9 diffus\u00e9s via des publicit\u00e9s malveillantes qui \u00e9taient utilis\u00e9es pour forcer le t\u00e9l\u00e9chargement de fichiers HTML Application sur des ordinateurs. Les utilisateurs qui ex\u00e9cutaient ces fichiers sur leurs PC d\u00e9clenchaient un processus d'infection en plusieurs \u00e9tapes impliquant des scripts Excel, JavaScript et PowerShell, ce qui conduisait finalement au t\u00e9l\u00e9chargement et \u00e0 l'installation du logiciel malveillant Nodersok.    <\/p>\n

Le logiciel malveillant lui-m\u00eame se compose de plusieurs composants destin\u00e9s \u00e0 remplir diff\u00e9rentes fonctions. Par exemple, un module PowerShell est utilis\u00e9 pour d\u00e9sactiver le Centre de mise \u00e0 jour et la protection Windows de base. De plus, il existe un module utilis\u00e9 pour \u00e9lever les privil\u00e8ges du logiciel malveillant dans le syst\u00e8me. Cependant, il y a aussi des applications l\u00e9gitimes : WinDivert et Node.js. Le premier outil est utilis\u00e9 pour capturer et interagir avec des paquets r\u00e9seau, tandis que le second permet d'ex\u00e9cuter JavaScript sur des serveurs web.<\/p>\n

Les rapports de Microsoft et de Cisco indiquent que le logiciel malveillant utilise deux applications l\u00e9gitimes pour ex\u00e9cuter un proxy sur les machines infect\u00e9es.de serveurs<\/a> Selon Microsoft, le logiciel malveillant transforme les n\u0153uds infect\u00e9s en proxy pour transmettre du trafic malveillant.serveurs<\/a> Dans le rapport de Cisco, il est mentionn\u00e9 que les serveurs proxy sont utilis\u00e9s pour effectuer des actions frauduleuses.<\/p>\n

<\/center><\/p>\n

Pour pr\u00e9venir l'infection, les sp\u00e9cialistes recommandent de ne pas ex\u00e9cuter les fichiers HTML Application d\u00e9tect\u00e9s sur le PC, surtout si leur provenance est inconnue. Quoi qu'il en soit, les fichiers qui se t\u00e9l\u00e9chargent de mani\u00e8re inattendue depuis des pages web sont toujours un mauvais signe et ne doivent pas \u00eatre consid\u00e9r\u00e9s comme fiables, quel que soit leur extension.     <\/p>\n
