Zusammenfassung

Am Anfang des Falls ist über die Details des Angriffs faktisch nichts bekannt. Es gibt noch keine sichergestellten Beweismittel, mit denen man eine Forensik machen kann. Es gibt keine Logs, die man durchsehen könnte. OSINT nennt man die Sammlung und Analyse von Daten aus frei verfügbaren Quellen („open source“), um Informationen für ein bestimmtes Thema zu gewinnen. Im konkreten Anwendungsfall geht es jetzt darum, die Ransomware-Gruppe zu identifizieren und möglichst viel über deren Struktur, die technische Vorgehensweise und das Verhalten in Verhandlungen herauszufinden. Die Ergebnisse einer guten OSINT-Recherche liefern Informationen, die oft auch tagelange forensische Analysen nicht produzieren können.
