Ende Januar wurde eine neue Art der Ransomware Snake identifiziert, die vermeintlich eine Kill-List zur Lahmlegung bestimmter ICS-Prozesse enthielt. Ersten Untersuchungen gemäß sei sie darauf angelegt, industrielle Prozesse zu stören, indem sie direkt auf die Ausrüstung des industriellen Kontrollsystems (ICS) abzielt. Sicherheitsforscher des Spezialisten für industrielle Cybersicherheit Claroty haben jetzt herausgefunden, dass dies jedoch nicht der Fall ist. Besteht also Grund zur Entwarnung? Leider nicht, denn durch die zunehmende Konvergenz zwischen IT- und industriellen Netzwerken besteht auch hier die Gefahr einer massiven Störung, wenn Angriffe auf IT-Systeme auch auf Produktionsstätten überspringen (Spillover-Effekt). Solche „Kollateralschäden“ konnten wir bei NotPetya und WannaCry ndibadijlm.
