It +exploits redundancy in the i386 instruction set by defining sets of +functionally equivalent instructions. It then encodes information in +machine code by using the appropriate instructions from each set. + +Features: + - Application filesize remains unchanged + - Message is blowfish encrypted with a user-supplied + passphrase before being embedded + - Encoding rate: 1/110 + +Primary uses for Hydan: + - Covert Communication: embedding data into binaries creates a + covert channel that can be used to exchange secret messages. + - Signing: a program's cryptographic signature can be embedded + into itself. The recipient of the binary can then verify + that it has not been tampered with (virus or trojan), and is + really from who it claims to be from. This check can be + built into the OS for user transparency. + - Watermarking: a watermark can be embedded to uniquely + identify binaries for copyright purposes, or as part of a DRM + scheme. Note: this usage is not recommended as Hydan + implements fragile watermarks. diff --git a/security/hydan/Makefile b/security/hydan/Makefile new file mode 100644 index 00000000000..ec107089fe2 --- /dev/null +++ b/security/hydan/Makefile @@ -0,0 +1,25 @@ +# $NetBSD: Makefile,v 1.1.1.1 2004/08/13 10:26:03 agc Exp $ + +DISTNAME= hydan-0.13 +CATEGORIES= security +MASTER_SITES= http://crazyboy.com/hydan/ + +MAINTAINER= tech-pkg@NetBSD.org +HOMEPAGE= http://crazyboy.com/hydan/ +COMMENT= Steganography tool for covert comms, signing and watermarking + +ONLY_FOR_PLATFORM= NetBSD-*-i386 FreeBSD-*-i386 Linux-*-i386 + +WRKSRC= ${WRKDIR}/hydan + +do-install: + ${INSTALL_PROGRAM} ${WRKSRC}/hydan ${PREFIX}/bin + cd ${PREFIX}/bin && \ + ${RM} -f hydan-decode hydan-stats && \ + ${LN} -s hydan hydan-decode && \ + ${LN} -s hydan hydan-stats + ${INSTALL_DATA_DIR} ${PREFIX}/share/hydan + ${INSTALL_DATA} ${WRKSRC}/README ${PREFIX}/share/hydan + ${INSTALL_DATA} ${WRKSRC}/README.details ${PREFIX}/share/hydan + +.include "../../mk/bsd.pkg.mk" diff --git a/security/hydan/PLIST b/security/hydan/PLIST new file mode 100644 index 00000000000..75106941b39 --- /dev/null +++ b/security/hydan/PLIST @@ -0,0 +1,7 @@ +@comment $NetBSD: PLIST,v 1.1.1.1 2004/08/13 10:26:03 agc Exp $ +bin/hydan +bin/hydan-decode +bin/hydan-stats +share/hydan/README.details +share/hydan/README +@dirrm share/hydan diff --git a/security/hydan/distinfo b/security/hydan/distinfo new file mode 100644 index 00000000000..9af75f5d880 --- /dev/null +++ b/security/hydan/distinfo @@ -0,0 +1,4 @@ +$NetBSD: distinfo,v 1.1.1.1 2004/08/13 10:26:03 agc Exp $ + +SHA1 (hydan-0.13.tar.gz) = 3c76bf1a1adb36a5124163cbbd55f9aff1afdb6e +Size (hydan-0.13.tar.gz) = 180409 bytes |
