High-speed railway power grid control system has been suspected of placing “worms†by US agents
According to the materials provided by China Railway, the Beijing-Shanghai high-speed rail contact network adopts lightning protection technology and electric ice melting technology to improve the comprehensive disaster prevention performance. As such, why is it still struck by lightning? China Railway Electrification Bureau Propaganda Department Director Wang Zhijian said on the phone yesterday that the situation is not as simple as you think. It is not a single sentence on the phone that can explain clearly.
According to the senior engineering level for repairing the grid, they spent an hour and a half to repair the faults of the catenary and pointed out that this is by no means an ordinary lightning strike. Because a general lightning strike will cause a momentary short circuit, it will recover in a few seconds. This time, there is only one possibility that causes the contact network to lose power for a long time. That is, the grid control system has a failure, that is, a software failure. According to another group of system engineers who inspected the grid control system, it was found that there are a lot of data with abnormal conditions and it is likely to be encountered by malicious software.
At present, the “worm†virus related to this invasive power grid control system has been extracted and sent to the National Computer Network and Information Security Management Center for further testing. According to preliminary analysis results, this worm virus invaded Iran in November last year. The centrifuge control system is similar. First, the normal grid voltage data is recorded. After the attack is successful, the voltage is out of control until the train fails. In order to maximize the destruction effect, the virus sends normal voltage data to the monitoring equipment at the same time, so that the alarm system and monitoring personnel cannot detect it in time. When the train stopped, the grid control center personnel thought that everything was normal and did not know what was happening. It was only after a phone call from the dispatching room that the problem was discovered.
According to an official of the National Security Bureau, they have acquired some basic information and said that this is a classified operation initiated by the United States and Japan. After the computer experts of the two countries created the virus, in May this year, they had done a simulation test on the control system of the Shinkansen power grid in Japan to ensure that the virus could effectively destroy the high-speed railway network.
When U.S. President Barack Obama took office, the United States launched the plan and ordered the implementation of the Beijing-Shanghai high-speed rail.
It was reported that the United Kingdom and Germany had informed or did not knowingly provided help for the production of this virus.
