Washington(ANN)- The Dark Overlord hacker group has threatened with leaking thousands of secret documents that it says will have devastating consequences for the US deep state, what some have termed the collection of members of permanent employees of the intelligence, security and diplomatic services that operate independent of changes in the administration.

The group has already released decryption keys for 650 documents it says are related to the September 11, 2001 terrorist attacks, but it is just a fraction of the 18,000 secret 9/11 documents probably stolen from insurers, law firms, and government agencies, RT website reported on Friday.

The hackers at the Dark Overlord have described the secret the September 11 documents as “the 9/11 Papers.”

The September 11 attacks were a series of strikes in the US which killed nearly 3,000 people and caused about $10 billion worth of property and infrastructure damage.

US officials assert that the attacks were carried out by 19 al-Qaeda terrorists but many experts have raised questions about the official account.

They believe that rogue elements within the US government, such as former Vice President Dick Cheney, orchestrated or at least encouraged the 9/11 attacks in order to accelerate the US war machine and advance the Zionist agenda.

The Dark Overlord announced on Wednesday a “tiered compensation plan” in which the people could make payments in bitcoins to unlock the troves of documents related to 9/11.

Following the announcement, the Dark Overlord said that people paid them $12,000 in bitcoin which are enough to unlock “layer 1” and several “checkpoints.”

But, according to the group, there are four more layers that are still encrypted and “each layer contains more secrets, more damaging materials… and generally just more truth.”

The hackers have demanded $2 million in bitcoin for the public release of “the 9/11 Papers.”
