On July 14, 2024, the ransomware group Blackout listed luzan5.com on its leak site, claiming that internal files had been exfiltrated from the small healthcare consulting company during a ransomware attack. Anyone whose personal or professional information passed through Luzan5’s systems may now be exposed, even though the exact number of affected individuals remains unknown.

Reported Details from the Listing
The Blackout leak-site entry states that Luzan5 suffered a ransomware intrusion and that attackers successfully exfiltrated internal files. The disclosure does not quantify how many records were taken, list specific data types such as patient names or Social Security numbers, or reveal the ransom demand. It simply states the breach occurred and that stolen data is now hosted on the group’s onion site. The listing carries a publication timestamp of July 14, 2024, and remains active, indicating the extortion window has not closed.
Internal files exfiltrated is the only description Blackout provides. No sample data has been publicly released in the initial posting, which is consistent with the group’s pattern of withholding proof files until later stages of their shaming campaign.
Why This Matters for You and Your Family
Healthcare consulting firms routinely handle names, dates of birth, addresses, insurance details, and sometimes clinical notes for clients and partner organizations. Even if you never directly hired Luzan5, your information could have been shared by a doctor’s office, employer wellness program, or insurer that used their services. Once those records leave a small vendor’s network, you lose control over who sees them. Families are particularly vulnerable because a single exposed parent record often links to children’s information through shared addresses or policy numbers.
