Kaseya has denied paying ransom money to REvil, the ransomware gang behind the latest attack on the company’s VSA product.

Monday’s statement came after questions were raised about the sudden appearance of a universal key, which some believe was only made possible by paying the ransom demanded.

The rumors intensified after some companies affected by the attack disclosed that Kaseya forced the companies to sign a non-disclosure deal in exchange for the decryptor.

CNN confirmed that Kaseya was requiring the non-disclosure agreement in order to gain access to the decryptor. The company made no comment on the non-disclosure agreement.

The decryptor has proved successful as the company made it available to some 1,500 victims of the attack.
