Stadler announced on Thursday evening that attackers managed to infiltrate its IT network and infect some of its machines with malware and, most probably, to collect and exfiltrate data from the compromised devices in the process. The company said that it took the steps needed to secure its computing systems immediately after and it also hired a team of external security experts to help with the incident’s investigation. Unknown perpetrators are asking for a ransom and are attempting to blackmail the company by threatening to leak stolen data.
