Swiss events organizer and marketing company MCH Group was hit by a malware attack on Wednesday (October 20), and says it is working to get systems up and running again.
The company has more than 700 employees and runs around 90 exhibitions, including the Art Basel shows in Basel, Miami Beach, and Hong Kong, as well as the watch and jewellery show Baselworld.
It says current and forthcoming exhibitions and events will still go ahead as planned.
“The internal ICT specialists, together with other external experts and the federal authorities, immediately took measures to limit the damage as far as possible,” it said in a statement.
“As part of this process, it will be investigated if any data have been siphoned.”
The company says it plans to file a criminal complaint.
