Les chercheurs en s\u00e9curit\u00e9 de Cisco Talos viennent de d\u00e9couvrir que des hackers sont parvenus \u00e0 exploiter une faille dans les serveurs de t\u00e9l\u00e9chargement d'Avast pour injecter un malware dans le logiciel CCleaner. Pendant une p\u00e9riode ind\u00e9termin\u00e9e, ce malware a \u00e9t\u00e9 install\u00e9 en m\u00eame temps que le logiciel sur l'ordinateur des utilisateurs. Cette cyberattaque dangereuse a potentiellement touch\u00e9 des millions de personnes.<\/strong><\/p>\n

\"ccleaner<\/p>\n

Le logiciel CCleaner est un outil tr\u00e8s pratique, qui compte parmi les meilleurs logiciels gratuits pour nettoyer son PC<\/a>. En un seul clic, il permet de supprimer tous les fichiers inutiles mais aussi et surtout les fichiers suspects sur le disque dur d'un ordinateur. Distribu\u00e9 par Avast, CCleaner a \u00e9t\u00e9 t\u00e9l\u00e9charg\u00e9 plus de deux milliards de fois, ce qui en fait l'un des logiciels\u00a0de s\u00e9curit\u00e9\u00a0les plus populaires \u00e0 ce jour. Ironiquement toutefois, le logiciel vient d'\u00eatre lui-m\u00eame la cible d'un malware.<\/p>\n

Afin de toucher un maximum de cibles, les hackers ont employ\u00e9 une technique de plus en plus utilis\u00e9e par les cybercriminels. Plut\u00f4t que de cibler les ordinateurs de victimes individuellement, le malware a \u00e9t\u00e9 inject\u00e9 directement dans les serveurs de t\u00e9l\u00e9chargement d'Avast. Ainsi, toutes les personnes qui ont t\u00e9l\u00e9charg\u00e9 CCleaner 5.33 au cours des derni\u00e8res semaines ont \u00e9galement t\u00e9l\u00e9charg\u00e9 sans le savoir un dangereux malware. Cette m\u00e9thode avait \u00e9t\u00e9 utilis\u00e9e plus t\u00f4t cette ann\u00e9e pour distribuer le ransomware Petya via les serveurs de la firme ukrainienne MeDoc.<\/p>\n
