- ADI says its operations were not interrupted during the incident and it does not currently expect a material effect on its business or finances.
- A new extortion group calling itself ExfilSquad publicly claimed on July 26 that it stole 570,000 records, but researchers have flagged inconsistencies and the claim remains unverified.
