The Taiwan Semiconductor Manufacturing Co. (TSMC) had several factories knocked offline late last week due to a cyber-attack.
The TSMC is the lone producer of the primary processor used in Apple iPhones and the attack came as the company was getting ready to start production of the chip for the latest version of that smartphone, reported Bloomberg News. The attack took place on Friday when several of TSMC's computer systems and factories and halted some operations. No details on the type of malware involved was released by the company.
"The degree of infection varied by fab. TSMC contained the problem and found a solution. As of 14:00 Taiwan time, about 80 percent of the company's impacted tools have been recovered, and the Company expects full recovery on 6 August," the company said in a statement.
TSMC did not give a detailed explanation of how the malware was inserted into its computer network placing the blame on an internal issue and not an outside attack.
"This virus outbreak occurred due to misoperation during the software installation process for a new tool, which caused a virus to spread once the tool was connected to the Company's computer network. Data integrity and confidential information was not compromised. TSMC has taken actions to close this security gap and further strengthen security measures," the company said.
