The PC maker has started writing to customers [PDF] warning that their personal records were siphoned off from its online store by crooks between May 12, 2015 and April 28, 2016.

Acer did not say how many customers had their details swiped.

The lost data includes customer names, addresses, card numbers, and three-digit security verification codes on the backs of the cards. Acer says that no passwords or social security numbers were obtained by the thieves, which will be of no comfort whatsoever to the victims.
