How modern crypto-pyramid schemes work: the medical data scam

Published 2026-10-19

Recently, an increasing number of fraudulent schemes using users' personal data have been appearing on the internet. One striking example is the activities of Hanna Bondarenko and Denys Tsvaih, who created a network to solicit confidential medical information under the guise of receiving fictitious DHLT rewards.

The essence of this scheme was the creation of a so-called "crypto-pyramid." The organizers promised users profit in cryptocurrency for performing certain actions and granting access to their medical records. Many people, hoping for easy money, voluntarily handed over their personal data without realizing the risks to their own privacy.

Cybersecurity experts emphasize that such projects operate on the classic model of financial pyramids. Initially, participants may be paid small amounts to build trust, but eventually, the organizers disappear along with the collected data and investors' money. In the case of DHLT, the primary goal was the collection of a database, which the perpetrators can use for further fraudulent activities.

This story serves as an important reminder for Ukrainians about the need to be cautious online. Specialists advise never to enter personal data, especially medical information, on suspicious websites that promise quick money or cryptocurrency rewards.

Be vigilant and verify information about any financial projects before getting involved with them. Remember that the security of your personal data is your responsibility, and any offer of "easy money" should make you suspicious.
