Cyberattack Disrupts Paris Wastewater Operations

November 22, 2023

INCIDENT

The organization that manages wastewater for nine million people in and around Paris was hit with a cyberattack on Friday. Service public de l'assainissement francilien – known by its acronym SIAAP — manages nearly 275 miles of pipes throughout four French departments. IT teams have worked since Wednesday to secure industrial systems and close off all external connections in order to prevent the attack from spreading.

Officials said they have prioritized measures that allow them to “maintain the continuity of the public sanitation service for Ile-de-France residents.”

“The SIAAP crisis unit remains mobilized to manage the aftermath of this attack and support the continuity of the work of all of its agents from this week in a working environment largely degraded by the current situation,” they said, according to a machine translation of the statement.

“This mobilization will continue until a return to normal can be ensured.”

The organization has set up local systems to answer any questions from the public and said they are in constant communication with various government agencies about the situation.
