Cette veille a pour objectif de suivre l\u2019\u00e9volution des ransomwares et du mod\u00e8le Ransomware-as-a-Service (RaaS), une menace majeure pour les entreprises. Elle vise \u00e0 :
\u2022 Comprendre les nouvelles techniques utilis\u00e9es par les groupes cybercriminels
\u2022 Identifier les groupes actifs et leurs modes op\u00e9ratoires
\u2022 Analyser les tendances du march\u00e9 criminel (industrialisation, professionnalisation)
\u2022 Anticiper les risques pour les entreprises
\u2022 Suivre les recommandations de d\u00e9fense publi\u00e9es par les organismes sp\u00e9cialis\u00e9s
Contexte d\u2019entreprise : Les entreprises, notamment les PME, sont aujourd\u2019hui fortement expos\u00e9es aux attaques par ransomware. Les services informatiques doivent adapter leurs strat\u00e9gies de s\u00e9curit\u00e9 pour r\u00e9duire les risques.
Mots-cl\u00e9s utilis\u00e9s : ransomware, RaaS, LockBit, Akira, Play, cyberattaque, double extorsion, chiffrement, fuite de donn\u00e9es, vuln\u00e9rabilit\u00e9s, cybercriminalit\u00e9.<\/li>\n\n\n\n
