Telecom says Yahoo!Xtra's most recent hacking ordeal is "a fact of life" given the prevalence of cyber criminals.
Email users with Yahoo!Xtra accounts were again affected by hacking overnight, just days after tens of thousands of Telecom customers suffered a security breach.
About 1500 accounts that did not have their passwords changed after the earlier Xtra hacking are understood to be affected by the latest breach, RadioLIVE reported.
On February 16, Telecom was forced to cancel 60,000 passwords for compromised accounts, where spam emails were sent to contacts in their address books.
Telecom released a statement today saying the latest breach wasn't anything special.
