Full contact information of everyone attending the BlackHat security conference this year has been exposed in clear text, a researcher has found. The data trove includes name, email, company, and phone number.
The BlackHat 2018 conference badge came embedded with a near-field communication (NFC) tag that stored the contact details of the participant, for identification or for vendors to scan for marketing purposes.
A security expert that uses the online moniker NinjaStyle noticed that scanning his badge with an NFC chip reader he could see his real full name in clear text.
