It then encodes information in machine code by using the appropriate instructions from each set.<br /> <br /> <br /> <br /> == Links ==<br /> * [https://web.archive.org/web/20110312045455/http://crazyboy.com/hydan/ Archived Homepage]<br /> * [http://mirror.sobukus.de/files/grimoire/crypto/hydan-0.13.tar.gz Download v0.13]<br /> * [https://web.archive.org/web/20041117205122/http://www.crazyboy.com/hydan/hydan-0.10.tar.gz Download v0.10]<br /> * [https://github.com/NetBSD/pkgsrc/tree/trunk/security/hydan/ NetBSD GitHub]<br /> * [http://www1.cs.columbia.edu/~angelos/Papers/hydan.pdf Hydan: Hiding Information in Program Binaries] - original paper<br /> * [https://www.youtube.com/watch?v=VAw3nc3mzpE Information Hiding in Program Binaries (Blackhat presentation)] ([https://www.blackhat.com/presentations/bh-usa-04/bh-us-04-el-khalil.pdf slides])<br /> * [https://www.giac.org/paper/gcih/6896/detecting-hydan-statistical-methods-classifying-hydan-based-stegonagraphy-executable-files/107335 Detecting Hydan- Statistical Methods for Classifying the Use of Hydan Based Stegonography in Executable Files]<br /> * [https://link.springer.com/chapter/10.1007/978-3-642-01244-0_12 Steganalysis of Hydan]<br /> * [https://www.informit.com/articles/article.aspx?p=102181&amp;seqNum=6 Description of how Hydan works] - chapter from book &quot;Malware: Fighting Malicious Code&quot;</div>
