Quantum — every breach we're tracking
Running log of incidents attributed to or claimed by Quantum in public reporting, with what was exposed and what victims should do. Updated as new incidents are ingested.
Groups like Quantum steal data first and extort second — and the stolen records rarely stay private. Once a victim organization's data hits a leak site, the personal details inside (names, emails, phones, addresses) get scraped into the same broker-and-dump ecosystem every doxxer searches. If an organization you've used appears below, treat your data as circulating.
