A hacker group known as Dark Overlord threatened on Monday to publicly release internal files regarding the 9/11 attacks unless their ransom demands are met. Overlord said it had breached a law firm handling cases related to the attacks and seemed to play up 9/11 conspiracy theories in its threat, saying in a tweet that the group will “be providing many answers about 9.11 conspiracies through our 18.000 secret documents.” “You're welcome to... make a request to formally have your documents... withdrawn from any eventual public release of the materials. However, you'll be paying us,” the group warned. Overlord claims to have hacked several different insurers and legal firms involved in insuring the World Trade Center and the legal battle that commenced after the towers fell. A spokesperson for one of the insurance companies confirmed to Motherboard that the hackers had breached a law firm that advised the company, and had likely stolen files related to litigation surrounding 9/11. This public extortion is only the latest by the group; they have already targeted a production studio working for Netflix, as well as medical centers and private businesses.
