SoftBank: member sites taken offline after an unauthorized access attempt on My SoftBank

On 19 October, SoftBank said a third party had attempted unauthorized access to some systems of its My SoftBank member site. On 17 October its monitoring system automatically detected abnormal activity in related systems, and it stopped some of them and blocked suspicious communication routes. To protect customer data, it took the My SoftBank, My Y!mobile and My Menu websites offline from 8 a.m. that day; the apps stayed available. On 22 October it said the My SoftBank website reopened around 9 p.m. on 21 October after security measures, while My Y!mobile and My Menu stay offline as work continues. The notices do not say whether any data leaked.

Every organization listed paused its services as a precaution; none is listed as hit.
