Payroll services provider ADP Australia recently published a list of customer e-mail addresses online by mistake.

"The list, which ADP said was dated 2007, was being used at the time to send out ADP client newsletters," writes ZDNet's Michael Lee. "The company said the list only contained email addresses and that no names, addresses or other details had been exposed."

"When the company discovered the information had been leaked, its managing director Richard Watson wrote to affected customers stating 'we do not have reason to believe that your email address will be misused as a result of this incident,' but conversely warned that 'you may receive an increased number of spam or phishing messages,'" Lee writes.
