About one in four companies revealed personal information to a woman’s partner, who had made a bogus demand for the data by citing an EU privacy law.
The security expert contacted dozens of UK and US-based firms to test how they would handle a “right of access” request made in someone else’s name.
In each case, he asked for all the data that they held on his fiancee.
In one case, the response included the results of a criminal activity check.
Other replies included credit card information, travel details, account logins and passwords, and the target’s full US social security number.
University of Oxford-based researcher James Pavur has presented his findings at the Black Hat conference in Las Vegas.
It is the first known test of its kind to exploit the EU’s General Data Protection Regulation (GDPR), which came into force in May 2018. The law shortened the time organisations had to respond to data requests, added new types of information they have to provide, and increased the potential penalty for non-compliance.
