“For a ransom of 10 BTC ($192,000), the risk actors promised the NAS vendor, QNAP, that they would share all the technological details relating to the zero-day vulnerability that they manipulated, and for 50 BTC ($959,000) they presented to consist of the master vital to decrypt the files belonging to the vendor’s clients who experienced fallen victim to the marketing campaign,” the report explained.
