Regroup is a ransomware actor observed in late 2023 victim-count reporting, where it accounted for a small share of publicly tracked incidents. High-confidence public reporting in the available data is limited to its identification as a ransomware group name and its appearance in incident tallies alongside other extortion actors. There is insufficient corroborated information in the available evidence to attribute Regroup to a specific country, define consistent targeting preferences, identify distinctive tradecraft, or assess whether it operates as a standalone group, affiliate brand, or rebrand of another ransomware operation.
