Disruptions to major European call center provider- Covisian after Conti Ransomware attack

On Saturday 18th of September 2021, GSS, the Spanish and Latin America division of Covisian was hit by a ransomware attack by the Conti ransomware gang. The attack led to them having to shut down a large portion of their IT systems and led to disruptions to call centers across its Spanish-speaking client base. Some of the impacted clients included Vodafone Spain, the MasMovil ISP, television stations, and Madrid’s water supply provider.

In a letter released by GSS’s executives, they announced that GSS has already taken down all their internal systems affected by the attack and are now utilizing Google-based systems as a backup system. They also claimed that there is “no evidence of any personal data leakage” and therefore there should be no effect on their clients.
