The client data and internal documents you’ve leaked go well beyond what you’ve seen here. We have taken several terabytes of files—this is just a small sample. In fact, we have obtained sensitive documents pertaining to virtually all of your clients. Warning: You have 3 days to enter negotiations. Once the deadline passes, the negotiation window will be permanently closed and all exfiltrated data will be published. Additionally, the encrypted data will be rendered completely unrecoverable. sample files: https://mega.nz/file/CgxxTKCZ#PzGFlZt67HDF2oLsP4jn_W_QdrquHJpNAfVm-jXGYxo https://mega.nz/file/2ogzwAyY#r8F31SFQTqyW6bzQA-e8HNzgw-rEW_gn7fhwY5TAByg https://mega.nz/file/2gIRXQwY#-4IzU70FjqvSYotZoaJuod_H2P5sXoGTvsja9Patte0 https://mega.nz/file/alQU0JaT#2GgaPb1Z-z1xB1FfAd_NohXbfkbfRfhfZ_OwtxPd0cc [Sector: Construction]

Leak-site claimThis record

Attacker assertion only. Establishes: claim date, group, alleged victim.

Press / market report

Unlocks: incident narrative, operational impact. Still no compliance clock.

State AG / regulator filing

Unlocks: discovery date, data types, affected count, compliance clock.

SEC 8-K / victim statement

Unlocks: materiality, stated response, full audit trail. Ceiling removed.

No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
