What happened
In early 2019 the ASX-listed property valuer LandMark White disclosed that roughly 137,500 valuation records — containing personal contact details of borrowers and property owners — had been exposed through an unsecured programming interface, and the data later appeared on a dark-web forum [lmw-itnews]. The breach cost the company around A$7 million; NSW Police later arrested and charged a man over it [lmw-itnews], [lmw-bna].
Current status
Before the courts. The 137,500 figure is a count of valuation records, not people, so no count of individuals is asserted here.
Why it matters
Property valuations quietly concentrate borrowers’ personal and financial context; the incident shows how an exposed interface can leak data at scale, with real commercial and legal fallout.
