BCT Technology affected by unauthorized network access


We would like to provide you an update on the current situation at BCT Technology AG/GmbH. 

We are still on a very good way to gradually restore our operational capability. 

Based on a consequently implemented "Green-Zone-Concept" for the entire IT environment we are again able to communicate securely with our customers and business partners via e-mail. The accessibility of BCT via landline telephone is also guaranteed. 

We would like to take this opportunity to apologize to all customers and business partners for the inconvenience caused by this security incident. 

According to current results of the analyses we are conducting together with external data forensics experts, there is still no evidence of any data leakage. 

We will continue to inform you regularly about the progress and thank you for your understanding.


A few days ago we issued a first information about the unauthorized access by an external attack to our network. We would like to provide you with a brief update on this matter.  

As stated in our initial information, we are well on the way to fully restoring our operational capability thanks to a quick response and very good cooperation with external IT security experts.  

We have decided for the safest option for our customers, partners and ourselves. This means that we are successively transferring our IT systems to a newly protected IT infrastructure. This process is progressing rapidly. 

According to the current results of  the data forensics experts, there is still no evidence of any data leakage. 

The process is still ongoing and we are working hard to ensure that all systems are safe again as soon as possible. 


Dear Customers,
Dear Business Partners,  

We are currently investigating an unauthorized access to the IT network of the corporate group with high priority. The access was identified on 04/20/2023, whereupon we immediately isolated relevant systems and shut them down in a controlled manner.  

Together with external experts, we launched a comprehensive review of our systems, which is currently still ongoing. As a result of the access and shutdown of the systems, we are temporarily unavailable by email and landline telephone.  

The following companies in our group are affected:  
Badische Stahlwerke GmbH, BSW Anlagenbau und Ausbildung GmbH,  
BSW Anlagentechnik GmbH, Badische Stahl-Engineering GmbH,  
BSW Stahl-Nebenprodukte GmbH, BCT Technology AG, BCT Technology GmbH and all wire processing companies.  

It is still unclear how the incident could have occurred. The security standards of our IT systems are very high and the security of your data is our top priority. We have informed all relevant authorities about the incident and are working closely with them to clarify the matter. 

The analyses are still ongoing and we assure you that we are making every effort to clarify the incident comprehensively and quickly. As soon as we have further relevant information, we will inform you immediately. 

Thank you for your understanding in this situation!
