In den vergangenen zwei Jahren ist es Angreifern gelungen, in die Systeme von 78 Prozent der deutschen Unternehmen einzudringen. Das zeigt die „Data Risk Management“ Studie von Veritas Technologies. Besonders beunruhigend daran ist, dass KI-Tools wie WormGPT es Angreifern erleichtern, ihre Social-Engineering-Angriffe durch KI-generierte Phishing-E-Mails zu verfeinern. Doch damit nicht genug: KI-gesteuerte, autonome Ransomware-Angriffe werden auch im Jahr 2024 vermehrt vorkommen.
Im Nachfolgenden erläutert Veritas die wirksamen Methoden und bewährte Tipps zur Abwehr von Cyberattacken, insbesondere im Hinblick auf Ransomware.
