March 27, 2023


Friedrich Vorwerk, a group of companies that builds gas pipelines and thus critical infrastructure (Kritis), was the victim of a cyber attack at the end of last year. Ransomware infected large parts of IT and paralyzed it. Since shortly before Christmas last year, the systems could be used productively again, the company said at the request of heise online. "As a result of a cyber attack that was averted at the end of the year, profitability was also impacted and visibility restricted".

"During the approximately 4-week work to repair our IT infrastructure, our ERP system and other parts of the infrastructure were not available. Shortly before Christmas 2022, the main effects were remedied and the systems could be used productively again. "
