PacketWhisper: Stealthily exfiltrate data and defeat attribution using DNS queries and text-based steganography. Avoid the problems associated with typical DNS exfiltration methods. Transfer data between systems without the communicating devices directly connecting to each other or to a common endpoint. No need to control a DNS Name Server.
Modes are tailorable in rate of queries, with faster rates risking detection and corruption, while slower speeds take significantly longer but are very stealthy to signature detection.
