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.
This group has 28 victims. The victim list API is currently responding slowly for this dataset. Country, sector, and infostealer breakdowns are not available at this time. Basic stats (victim count, first/last seen) are shown above from a faster data source.
