Akamai-Sicherheitsforscher enthüllen unerwartetes Verhalten von DGA-Familien

(PresseBox) (Garching, )
Malware muss häufig mit einem zentralen Server kommunizieren, um Befehle oder Updates zu erhalten. Dabei kommen sogenannte domaingenerierte Algorithmen (DGAs) zum Einsatz, um eine große Anzahl von semirandomisierten Domainnamen zu generieren.

Sicherheitsforscher von Akamai haben das ungewöhnliche Verhalten von DGA-Familien mit dynamischen Seeds in DNS-Verkehrsdaten entdeckt. Das merkwürdige Verhalten deutet darauf hin, dass böswillige Akteure diese DGAs modifiziert haben, um die Erkennung weiter zu erschweren. Sie verlängern die Lebensdauer ihrer C2-Server, um so ihre Botnets zu schützen.
