The document dump is just a fraction of the 18,000 secret documents related to the September 11, 2001 terrorist attacks believed to have been stolen from insurers, law firms, and government agencies.
The Dark Overlord initially threatened to release the 10GB of data unless the hacked firms paid an unspecified bitcoin ransom. However, on Wednesday, the group announced a “tiered compensation plan” in which the public could make bitcoin payments to unlock the troves of documents.
A day later, the Dark Overlord said that it had received more than $12,000 in bitcoin – enough to unlock “layer 1” and several “checkpoints,” comprised of 650 documents in total.
There are four more layers that remain encrypted and, according to the group, “each layer contains more secrets, more damaging materials… and generally just more truth.”
