We have been made aware by Bombardier of a serious cyber security incident and are naturally disappointed that this has resulted in some material we provided to them as part of a joint project being published on the Dark Web.

However, we have a proven, effective and comprehensive approach to cyber security within Marshall Aerospace and Defence Group and are therefore working collaboratively with Bombardier to assist them in their response to their security breach and to identify any mitigation actions that need to be taken to ensure the containment of this incident.

At this stage it would be inappropriate for Marshall to make any further comment.
