We have produced a case study of the cyber attack against Gloucester City Council so that other councils can learn from their experience.

In December 2021, Gloucester City Council was the subject of a targeted ransomware attack which encrypted its servers and temporarily prevented the council from providing services which relied on the data held on those servers.


This case study is based on the first hand experiences of key staff at the council of dealing with the cyber attack.  It includes a timeline of the attack, its impact, the recovery process, the cost of the incident, and the lessons learnt by the council.
