TSMC grabs efficiency | Factory connection has become a security loophole

TSMC is the leading semiconductor industry in Taiwan, with annual revenues of 900 billion yuan. This time, due to operational errors, it was planted on the 'WannaCry' variant virus. I am afraid I have to pay more than 5 billion yuan in 'tuition fees'. Wei Zhejia, President of TSMC Yesterday, frankly, there was only one machine, but it was infected with the whole production line. Wei Zhejia explained that the TSMC production system is interconnected. It was originally the advantage of TSMC because it can increase production efficiency, but it also caused the three major factories in North, Central and South. Both are infected by viruses, and a firewall between the factory networks will be established in the future. As for overseas factories, because there is a firewall, it has not been affected.

Wei Zhejia said that in addition to the above-mentioned reasons, the poisoning of the new machine has not been cleaned up, and the machine and operating system use Windows 7 without installing the correction software.

Wei Zhejia was not willing to explain the way of virus spread, the type of machine and the supplier who had problems. He only said that when the operator installed the new machine, the machine was not isolated before the network was connected to ensure no virus, causing the virus to enter the company network. Although there is only one machine that has problems, TSMC's production network is connected, so all machines are infected.

Wei Zhejia pointed out that TSMC has certain procedures for installing new machines. This time, the human error is that the new machine will start to install anti-virus software when it is connected to the Internet. In the future, when TSMC's new machine is connected to the Internet, it will continue to be checked. Will increase the system automatic check, so that the anti-virus machine can not go online, eliminate human factors, and will establish a firewall to avoid this event replay.

The rumors of TSMC 'infecting the virus through U S B' are very rampant, Wei Zhejia said, the virus should be in the new machine, not the employee. The virus is a variant of 'WannaCry', he does not think it is a customized virus specifically for TSMC.

In addition to the unimplemented anti-virus SOP, he said that the infected machine and automatic handling system, and related computer systems, mainly use Window 7, but did not install the correction software on the machine automation interface, resulting in the affected The machine is not working, and some automatic handling systems are not working properly.

Wei Zhejia pointed out that 'there are some machines that don't imagine simple.' If the old computer needs to install the update system, it still needs to work with the original manufacturer to have a solution. 'We will find the right time, the whole production line, the whole machine Have to install the correction software'.

The outside world is concerned about whether TSMC has insurance for insurance. He Limei, chief financial officer, said that the current security insurance on the market is to protect personal capital leakage and not to protect property losses. Therefore, manufacturing plants like TSMC have lost production due to viruses. No insurance.
