How I Hacked BlackHat 2018

BlackHat is one of the world’s largest cybersecurity events which takes place in the USA in Las Vegas every summer (https://www.blackhat.com/us-18/). Those who have attended BlackHat may have noticed that their badge contains an NFC tag. This NFC tag is scanned at booths in the Business Hall so vendors can collect their marketing data including name, address, company, job title, and phone number. Following BlackHat, attendees who have had their badges scanned by various vendors then receive a barrage of marketing emails.
