The Australian Federal Police (AFP) warned Australian IT security
professionals at last week's AusCERT 2010 conference to do penetration testing
on their telephone systems or risk having their PABX hacked.
"PABX hacking and fraud ... is happening more and more," AFP investigator
Alex Tilley said. "It's been around for donkey's years, but in the last few
months we've seen domestically and globally a major up kick in the amount of
money that's being lost through PABX hacking," he said.
