Signal Intrusion
Cases where an entirely unauthorised signal successfully broke into a secure or official broadcasting channel. We scrutinise the raw transmission logs alongside subsequent technical reports. This allows us to establish exactly how the interruption bypassed security and identify who actually possessed the technical means to execute it.
