This payload does covert timing-channel data exfiltration by running a local command, encoding each character’s ASCII value as a delay between network probes, and letting a receiver reconstruct the output from the probes’ timestamps.
Exfiltration is an involuntary backup. It's a technique for obtaining data from a network. Once obtained, the data may be removed using a number of methods. These may include traversing the network to a command and control server, such as Cloud C². The content is typically encrypted or obfuscated. In the case of physical access, a bring-your-own-network element may be included to evade detection. See all exfiltration payloads.
This payload is for the USB Rubber Ducky — a "flash drive" that types keystroke injection payloads into unsuspecting computers at incredible speeds. It's no wonder this little quacker has made appearances on Mr. Robot, FBI, Blacklist, National Geography and more!
