Databreach at European Telecommunications Standards Institute (ETSI)

November 30, 2023


On 27 September 2023 the European Telecommunications Standards Institute (ETSI) reported that hackers have stolen a database identifying its users.
It is not yet clear whether the attack was financially motivated or if the hackers had intended to acquire the list of users for espionage purposes.

Following the incident, ETSI, which is based in the Sophia Antipolis technology park in the French Riviera, said it brought in France’s cybersecurity agency ANSSI “to investigate and repair the information systems.” The nonprofit said the “vulnerability on which the attack was based has been fixed,” although it did not identify the vulnerability.
