Taiwan Semiconductor Manufacturing Company (TSMC) (TPE:2330) on Saturday announced that a number of their machines used at the fabrication facilities had been infected with a virus, but that they had reached containment as of Saturday.

While some of the events took a full day to resolve, some of them were resolved in a “short period of time.” The frequency and source of the attackers is not mentioned in any statement, nor is it known at the time of writing as to why TSMC would be having their infrastructure attacked in such a manner, but at this point, according to their statement, “TSMC has contained the problem and found a solution, and recovery of the tools is in progress” with all facilities up and running by the end of August 6th. There is of course the possibility that TSMC wasn’t deliberately targeted and an employee just opened the wrong email attachment. The total impact of this event is unknown, as variables such as number of affected facilities, number of pieces of equipment, frequency of infection and duration of infection haven’t been made available.
