On March 25, 2025, the ransomware group Cicada3301 added I.A.T.S.E. Local 667/669 to its leak site and began a countdown timer showing 29 days, 22 hours remaining. The group claims to have stolen 125 GB of internal files from the union that represents film, television, and theater technicians across Canada.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

What Public Reporting Shows
Available reporting describes the incident as a ransomware attack in which Cicada3301 exfiltrated internal documents before encrypting systems. The leak page lists the victim organization, the claimed volume of data, and a live countdown. No independent confirmation of the exact number of individuals affected has been published, but union membership rolls and vendor records typically contain names, addresses, contact details, Social Security or Social Insurance numbers, banking information for direct deposit, and employment contracts. Public reporting indicates the data remains accessible only on the Cicada3301 onion site at the time of writing.
Why This Matters for You and Your Family
If you or anyone in your household works in film, stage, broadcast, or related technical trades, your personal information may now sit inside the 125 GB archive. Even if you are not a direct member of Local 667 or 669, family members, contractors, or vendors whose records were stored on the same systems could be exposed. Once this volume of internal files reaches underground forums, the information can be used for identity theft, tax fraud, phishing campaigns, or sold in batches to other criminals. The March 25, 2025 listing means the clock is already running; many ransomware groups publish or sell data once their deadline expires.
The Doxxing and Identity-Chain Implications
Credential leaks and internal documents rarely stop at one organization. A single email address or phone number taken from union records can be correlated with gaming accounts, social-media handles, and school registrations. This creates an identity chain that links your professional life to your family’s online presence. Public reporting indicates such chains frequently lead to doxxing, swatting, or targeted extortion. Gaming accounts belonging to you or your children are especially vulnerable because the same password or recovery email reused from a work-related breach can hand over an account in minutes.
