Andauernde Cyberbedrohungen gegenüber U.S. Wasser- und Abwassersystemen

Quelle: FBI, CISA, EPA, NSA

Mitte Oktober haben das FBI, CISA, EPA und NSA ein Advisory veröffentlicht, in dem es um andauernden Cyberangriffe auf die Wasserwirtschaft in den USA geht.

Folgende Vorfälle sind gelistet:

  • In August 2021, malicious cyber actors used Ghost variant ransomware against a California- based WWS facility. The ransomware variant had been in the system for about a month and was discovered when three supervisory control and data acquisition (SCADA) servers displayed a ransomware message.
  • In July 2021, cyber actors used remote access to introduce ZuCaNo ransomware onto a Maine-based WWS facility’s wastewater SCADA computer. The treatment system was run manually until the SCADA computer was restored using local control and more frequent operator rounds.
  • In March 2021, cyber actors used an unknown ransomware variant against a Nevada-based WWS facility. The ransomware affected the victim’s SCADA system and backup systems. The SCADA system provides visibility and monitoring but is not a full industrial control system (ICS).
  • In September 2020, personnel at a New Jersey-based WWS facility discovered potential Makop ransomware had compromised files within their system.
  • In March 2019, a former employee at Kansas-based WWS facility unsuccessfully attempted to threaten drinking water safety by using his user credentials, which had not been revoked at the time of his resignation, to remotely access a facility computer.

Die Angriffe sind bis zum Weißen Haus hin thematisiert worden.
