Stegodon
Stegodon by leechy9 (Derek Menteer) is an open source Python script that hides a file in an xml file.
Erases tail data in each node of the xml. Each node in the xml tree has 0 or more spaces in its tail data. Each space represents a 1 for a bit, while each new node represents a 0. The bits are written in lsb order, which appears backwards when read sequentially, making most patterns less obvious.
To further hide the information, the nodes are accessed in depth-first order. This means the bits may not appear in sequential order and are almost impossible to detect without first knowing that the data follows the depth-order scheme and parsing the xml.
A tab character is used to denote the end of the stegged content. The ratio of storage between the hidden document and the carrier is inconsistent and very poor, so this should only be used to hide small files.
