On 20 October 2021, MCH Group was hit by a criminal cyber attack using malware. Our IT specialists immediately took measures to defend against the attack and restore the IT systems. In doing so, we are working closely with security and cybercrime specialists, including the Swiss National Cyber Security Centre (NCSC), the police and partners specialising in such cases.
We are working to get all our systems and services fully operational again as soon as possible. The most important internal and external communication channels are ensured. The staging of the planned events is guaranteed.
Unfortunately, the available information and analyses indicate that the perpetrators have nevertheless succeeded in gaining access to data that contains personal data (e.g. contact details) of customers, partners and employees of the MCH Group. Currently, the existing traces are being evaluated in cooperation with cybersecurity experts.
We will not abet such criminal activities and have filed a criminal complaint against the perpetrators unknown to us and informed the relevant authorities and cooperating closely with them.
We have taken the necessary measures to protect our employees, customers and partners and continue to work with a wide range of internal and external specialists to resolve the issues. The knowledge gained from this incident will help us to make our systems, which already meet high security requirements, even more secure.
If you are a customer or partner of the MCH Group, as a precautionary measure, we recommend that you change your passwords or access data associated with the MCH Group immediately . However, this is not yet possible for some systems for exhibitors and partners at the moment (further information will follow as soon as possible). Please note that you also make these changes for accounts and services for which the MCH Group is not responsible, but for which you have used the same password.
We also recommend that you exercise caution when dealing with unknown contacts, e.g. if you are contacted by third parties by e-mail or telephone who, for example, represent themselves as your bank, internet provider or insurance company and use personal details to gain your trust.
