Following a privacy lapse in December that exposed Telstra customers' personal information online, the company has done it again.

"This time, according to, the breach involves customer data being posted to a cloud-based spreadsheet service," writes The Register's Richard Chirgwin. "The site says the data was apparently put on the site by a consultant in training (apparently and stupidly using live data)."

"The new data breach includes customers’ contact details and dates of birth, but according to Telstra, no credit information or passwords," Chirgwin writes.
