Un nouveau ransomware baptis\u00e9 Try2Cry a \u00e9t\u00e9 r\u00e9cemment mis en lumi\u00e8re par le chercheur en s\u00e9curit\u00e9 informatique Karsten Hahn, analyste pour l'\u00e9diteur d'antivirus G Data Software. D'apr\u00e8s ses informations, ce ran\u00e7ongiciel tente de se frayer un chemin vers d'autres PC en infectant les cl\u00e9s USB reli\u00e9es \u00e0 l'appareil actuellement attaqu\u00e9.\u00a0<\/strong><\/p>\n
Apr\u00e8s avoir infect\u00e9 un appareil, Try2Cry s'occupe de chiffrer les fichiers .doc, .jpg, .xls, .pdf, .docx, .pptx, .xls et .xlsx<\/strong> et ajoute ensuite une extension .Try2cry sur tous les fichiers concern\u00e9s. Les donn\u00e9es sont chiffr\u00e9es \u00e0 l'aide de Rijndael, un algorithme de chiffrement sym\u00e9trique employ\u00e9 par le standard AES. Mais comme dit plus haut, la caract\u00e9ristique la plus \u00e9tonnante de ce ransomware est sa facult\u00e9 \u00e0 se propager via les cl\u00e9s USB.<\/p>\n
