A German steel factory suffered significant damage after attackers gained unauthorized access to computerized systems that help control its blast furnace, according to a report published Friday by IDG News.
The attackers took control of the factory's production network through a spear phishing campaign, IDG said, citing a report published Wednesday by the German government's Federal Office for Information Security. Once the attackers compromised the network, individual components or possibly entire systems failed. IDG reporter Loek Essers wrote:
Due to these failures, one of the plant’s blast furnaces could not be shut down in a controlled manner, which resulted in “massive damage to plant,” the BSI said, describing the technical skills of the attacker as “very advanced.”
The attack involved the compromise of a variety of different internal systems and industrial components, BSI said, noting that not only was there evidence of a strong knowledge of IT security but also extended know-how of the industrial control and production process.
