A critical partner for the launch of the new iPhone the Company is able to volume produce of 7mm chips, which will drive performance while limiting energy usage in the new iPhones.

TSMC (Taiwan Semiconductor Manufacturing Co) is one of the world's largest semiconductor manufacturers and provides slices of silicon and electronics to all manner of big names, notably Apple, AMD, Qualcomm and Nvidia. Apparently, a "misoperation" during the installation of a new tool allowed the virus to spread to the entire network as soon as the new device was hooked up to it. "TSMC has taken actions to close this security gap and further strengthen security measures", it said. The impact on Apple's iPhone production schedule is also not known, although TSMC expects the incident "to cause shipment delays and additional costs".
TSMC said the disruption is expected to knock 3% off its third-quarter revenue, which it had previously forecast would be in the range of $8.45 billion and $8.55 billion.
Of course, Bloomberg was most interested in the possible consequences to the production of Apple iPhone chips.
A bellwether for the chip industry as well as an early indicator of iPhone demand, TSMC heads into its busiest quarters grappling with waning enthusiasm for the high-powered chips used to mine digital currencies.
While purely speculation until such time as TSMC comments, speculation points to the company getting hit, intentionally or unintentionally, by a ransomware attack.
