AT LEAST 16 residents living in Hillgrove and Yarrowick are among nearly one million Australians who risk being exposed as unfaithful partners in the hacking saga of infidelity website Ashley Madison.
The site, which targets users looking for sex outside of their marriages, is being blackmailed by a group calling itself The Impact Team, which has threatened to publish customers' profiles and credit card details.
NationMaster, a free Australian suburb profiling site, has identified 16 paid Ashley Madison accounts in the 2350 postcode.
When examined further, the accounts are from Hillgrove and Yarrowick.
The postcode is ranked 354 out of 478 NSW postcodes with registered Ashley Madison accounts.
According to the data, inner Sydney, including Haymarket and Dawes Point, is the most adulterous postcode; the least adulterous postcode area is Ashby in the Maclean, ranked at 478 in NSW.
The Impact Team provided apparently random samples of data from about 40 million accounts to prove its bona fides.
The Impact Team claimed the attack was in retaliation to claims by Ashley Madison's parent company Avid Life Media that all customer information could be permanently erased from the site.
The hackers drew attention to a quote from the parent company's chief technology officer Trevor Stokes: "Protection of personal information" was his biggest "critical success factors", and "I would hate to see our systems hacked and-or the leak of personal information".
"Well Trevor, welcome to your worst f--king nightmare," The Impact Team said in their statement.
The hack follows an attack on adult dating site Adult FriendFinder earlier this year, as well as previous attacks on Cupid and Grindr.
