Officers from the AFP contacted iTnews within two hours of posting a story on the data security breach.
The 19,000 credit card numbers are still visible in a Google cache as this story is published, but the AFP assured iTnews the law enforcement agency is doing all within its powers to minimise the damage caused to those Australian customers whose personal and financial data were laid bare on the web.
The AFP said it has been in contact with the credit card companies that issued the cards.
A thread on broadband forum site Whirlpool discussing the exposure of the credit card details has also been closed.
The thread now reads:
"This thread has been deleted. Reason: being handled by the Federal Police."
