According to ChainCatcher, as reported by Cointelegraph, a batch of data containing sensitive information about cryptocurrency conference attendees is circulating in the market. These lists may contain full names, phone numbers, nationalities, job roles, and companies, as well as personal and corporate social media links. Some lists even include attendees' ticket purchase dates, ticket types, operating systems used for purchasing tickets, number of social media followers, cryptocurrency wallet addresses, and information entered in text fields sent to event organizers.
Cointelegraph obtained 'samples' of such lists from sellers via Telegram, which include four lists of approximately 60 to 100 participants each, seemingly from multiple events, with each list containing different data points about attendees. One seller has access to lists from multiple countries, indicating that the international trade of blockchain event attendee data is not isolated but organized.
It is worth noting that the investigation shows that data resellers are suspected to be from Russia. The sellers claim that this data will be used for "marketing promotion and finding customers," and even attempt to justify the sale of "unleaked" data by claiming that this data "is not sensitive information" and that "most people are open to this type of marketing."
