Does anyone know what crime is being investigated? It looks like the malicious activity was sending spam text messages and forwarding international phone calls. Is there a federal regulation against sending spam messages?

Is it somehow illegal to have many sim cards in the same place as having many radios?

The telco's are also capable of bringing down the network, and they are legally allowed to turn their services off. Its not government infrastructure, its a business. If the backbone ISP providers decided to turn off their services for an area for a time, thats fine, there are contractual provisions to deal with that. its not a crime.

There has been no mention of arrest, was this 'crime' perpetrated by the infamous hackerman in ablack hoodie?
