Telstra has become the latest telco to be managing a smaller breach of its staff data, as millions of Australians rush to protect sensitive details stolen in the Optus cyber attack.
A Telstra spokesman confirmed up to 30,000 former and current workers have had their names and email addresses uploaded to a forum on the dark web.
He said Telstra itself was not hacked, but a third party which was offering a rewards program for staff had the data breach in 2017.
