What happens when your supplier installs software without virus-scanning technology? A virus gets loose and spreads, knocking operations offline. That can result in revenue loss and delays. Fortunately for Apple, its chip supplier, TSMC, is back online and expects to be able to fill orders on time. Unfortunately for TSMC, it’s expecting Q3 potential revenue loss to the tune of nearly $200 million.
Bloomberg reports that the malware, which is a variant of WannaCry ransomware, took production down over this past weekend. By Sunday, however, operations had resumed.
The chip maker’s production information and customer data were unaffected, ZDNet says, but fabrication tools and automated materials handling related systems were. These systems relied on Windows 7, which had not been patched. As a result, tools became inoperable.
According to Bloomberg, TSMC takes pride in its technological and operational superiority. The chip maker’s CEO, C. C. Wei, told Bloomberg that no hacker targeted TSMC. Rather, Bloomberg reports, “The infected production tool was provided by an unidentified vendor. The company is overhauling its procedures after encountering a virus more complex than initially thought.”
