The group has been active since 2022 and has been linked to rapid data theft operations.
- ▪The gang has targeted dozens of banks, law firms, and other professional services companies in the US from January through May 2026.

- ▪The entire operation from initial contact to data extortion can occur in just one day, with some incidents taking less than an hour.
