More and more hacking organizations are now targeting large enterprises and government agencies. For hackers, this has higher potential benefits than infecting home users. Many municipal networks have been temporarily closed due to ransomware attacks, and this time Frankfurt encountered malware. Frankfurt is one of the world’s largest financial centers and is also home to the European Central Bank. However, Frankfurt had to shut down its network due to the attack. Fortunately, this attack was not ransomware, so no data was encrypted. After temporarily closing and cleaning up the malware on the network, the network has now been restored.
According to a survey by local law enforcement agencies and IT experts, the malware-infected in Frankfurt this time does not encrypt any files but tends to infect critical systems. After successfully infecting the local network, the malware has no new operations but is waiting for the hacker organization behind to issue new operating instructions through the remote server. Although the hacker successfully infected Frankfurt’s internal network this time, Frankfurt detected the attack in time and closed the network. The malware was subsequently cleaned up.
Although Frankfurt survived the cyber attack this time, the temporary closure of the network also caused very serious losses to local government agencies and enterprises. In the beginning, the network administrator in Frankfurt was not willing to shut down the network temporarily. The administrator also knew that even a temporary shutdown of the network would have a great impact. However, under the suggestion of the German cybersecurity agency BSI security experts, Frankfurt still chose to close the network and then began to clean up various types of malware in the intranet. Security experts say that only by thoroughly cleaning up the malware can avoid greater damage in the future, so temporarily shutting down the network is necessary but necessary.
