Detailed analysis
The only retrieved evidence is a November 5 news report quoting Chainalysis as saying 'certain customer information including names, usernames, password hashes and live tokens for all Chainalysis users were exposed.' The report does not provide technical forensic detail, explicit timelines for restoration, or confirmation of product outages. Because only this contemporaneous media report was retrieved, claims about specific product downtime, phased restorations, or the date of a corporate blog update have been removed.
