According to security researcher Chuong Dong, who analyzed the new ransomware, Babuk Locker’s encoding is amateurish but includes secure encryption that prevents victims from recovering their files for free. “Despite the amateur coding practices used, the strong encryption scheme using the Elliptic curve Diffie-Hellman algorithm has so far proved effective in attacking many companies,” said Dong in the report. It is stated that there have been ransom demands ranging from 60 thousand to 85 thousand until now.
