onyx

Onyx is a ransomware group first observed in April 2022, based on the Chaos ransomware builder, that is notably destructive — files larger than 2MB are overwritten with random data rather than encrypted, making recovery impossible even after ransom payment — claiming approximately 13 victims across six countries.
