So the other day I was on a pen test and I got hold of the hashes. Since my laptop got fried I needed a new version of SMBProxy<\/a>. There were a few issues that I had with the compilation though. I got a few errors in the file crypto.c.
Moreover, SMBProxy ues crypto library libdes written by Eric Young available here<\/a>.
I give here a guide to compiling SMBProxy that worked for me.<\/p>\n

First, compile and install libdes<\/p>\n

    \n
  1. Download libdes 4.01<\/a><\/li>\n
  2. tar zxvf libdes-4.01.tar.gz<\/span><\/li>\n
  3. cd libdes<\/span><\/li>\n
  4. make gcc<\/span><\/li>\n
  5. sudo make install<\/span><\/li>\n<\/ol>\n

    Now, you’ll find that the file libdes.a is now in \/usr\/local\/lib.
    Second, compile and install SMBProxy. Now here there were a couple of compilation errors that I had to deal with.
    Here’s the diff output for crypto.c<\/p>\n

    trance@z0n3:~\/Desktop$ diff smbproxy\/crypto.c smbproxy-orig-src\/crypto.c<\/span>
    <\/span>40,41c40<\/span>
    <\/span>< #include <\/span>
    <\/span>< #define MD4_SIGNATURE_SIZE 16 --- ><\/span>
    <\/span>46c45<\/span>
    <\/span><> static u_char Get7Bits(UCHAR *input, int startBit) {<\/span>
    <\/span>58c57<\/span>
    <\/span><> static void MakeKey(UCHAR *key, UCHAR *des_key) {<\/span>
    <\/span>74c73<\/span>
    <\/span><> void DesEncrypt(UCHAR *clear, UCHAR *key, UCHAR *cipher) {<\/span>
    <\/span>85c84<\/span>
    <\/span><> void mkResponse(UCHAR **ntlmhash, UCHAR hash[MD4_SIGNATURE_SIZE], UCHAR* challenge) {<\/span>
    <\/span>88c87<\/span>
    <\/span><> UCHAR ntlm_response[24];<\/span>
    <\/openssl><\/span><\/p>\n

    Having done this there were still a few issues with the make comand.
    The Makefile can be generated by running the following command:<\/p>\n

    trance@z0n3:~\/Desktop\/smbproxy-orig-src$ .\/configure<\/span>
    <\/span>
    Here’s the diff output of the Makefile:<\/p>\n

    trance@z0n3:~\/Desktop$ diff smbproxy\/Makefile smbproxy-orig-src\/Makefile<\/span>
    <\/span>10,11c10,11<\/span>
    <\/span>< smbbf_include =\" -Iinclude\"><\/span>
    <\/span>< libs =\"\">
    <\/span>—<\/span>
    <\/span>> SMBBF_INCLUDE = -Iinclude<\/span>
    <\/span>> LIBS = des<\/span>
    <\/span>31c31<\/span>
    <\/span>< $(LIBDES) $(LIBS)<\/span>
    <\/span>—<\/span>
    <\/span>> $(LIBDES)<\/span><\/p>\n

    <\/span><\/span><\/span>The following libraries are required: openssl, openssl-dev, libdes for successfully compiling SMBProxy.<\/p>\n

    apt-get install openssl openssl-dev<\/span>
