Based on the information currently available, we have advised healthcare organisations to take appropriate mitigating measures, such as temporarily disabling vulnerable systems or increasing monitoring activities.
Z-CERT remains in close contact with the National Cyber Security Centre (NCSC) regarding this matter. Citrix has now published a security advisory and released security updates. We advise organisations using the affected products to install these patches as soon as possible and to remain vigilant for any signs of compromise or misuse.
We will continue to monitor the situation closely and will share relevant information with our participants and constituent entities where appropriate.
