A major virus infection forced the closure of Taiwan Semiconductor Manufacturing Company (TSMC) factories last weekend…” writes Slashdot reader Mark Wilson, noting that it’s the largest semiconductor manufacturer in the world, selling chips to Apple, Nvidia, AMD, Qualcomm, and Broadcom, and “responsible for producing iPhone processors.”
Now Network World reports:
The infection struck on Friday, August 3, and affected a number of unpatched Windows 7 computer systems and fab tools over two days. TSMC said it was all back to normal by Monday, August 6. TSMC did not say it was WannaCry, aka WannaCrypt, in its updates, but reportedly blamed WannaCry in follow-up conference calls with the press…. The company said this incident would cause shipment delays and additional costs estimated at 3 percent of third quarter revenue. The company had previously forecast revenues of $8.45 billion to $8.55 billion for its September quarter. A 3 percent loss would mean $250 million, though actual losses may come out lower than that. Still, that’s a painful hit. TSMC also said no customer data was compromised….
TSMC isn’t directly to blame here; someone [an infected production tool provided by an unidentified vendor] brought WannaCry into their offices and behind their firewall, but TSMC is still culpable because it left systems unpatched more than a year after WannaCry hit.
