Topic: MD5 Checksums
- -----------------------------------------------------------------------------
This advisory gives the MD5 checksums for a number of SunOS files, along
with a tool for checking them. The checksums can be used to assure the
integrity of those files.
The CERT Coordination Center is distributing these checksums because of an
increasing number of incidents in which intruders who gain root access
are modifying system files to install Trojan horses.
Moreover, intruders are modifying files so that they have the same checksum
as the original file. This is possible because the standard "sum" program
that comes with most UNIX systems was designed to detect accidental
modifications to files and is not strong enough to prevent deliberate
attempts to yield a specific checksum. The MD5 algorithm by RSA Data
Security, Inc. is specifically designed to provide checksums that cannot
be deliberately spoofed. We strongly recommend that sites install the
MD5 software and use it to validate system software. More information
on obtaining MD5 is given below.
The list of checksums in Appendix B of this advisory is provided for
your convenience. In addition, we are providing a program that can assist
you in checking your MD5 output against the values in the database.
This checksum list is not complete. We have begun with a number of
the more common locations for Trojan horses that we have seen in
connection with the continuing "sniffer" attacks reported in CA-94:01
"Ongoing Network Monitoring Attacks." We intend to work with
all vendors to expand this list and make more MD5 checksums widely
available for anonymous FTP.
Note: After we publish checksums in advisories, files are sometimes updated at
individual locations because of system upgrades or patch installation. For
current MD5 checksum values, we recommend that you check with your vendor.
We encourage sites to consider installing a more complete package for
monitoring system integrity, such as Tripwire from the COAST project
ftp://ftp.cs.purdue.edu/
or the TIGER system from TAMU
ftp://net.tamu.edu/pub/security/TAMU/
- -----------------------------------------------------------------------------
I. Description
Intruders are installing Trojan horses by modifying system files
often in such a way that a standard checksum on the file generates the
same checksum as the unaltered version.
II. Impact
The Trojan horses give the intruder continued access to a system
and/or hide the intruder's activities.
III. Solution
1. Obtain and install MD5.
The MD5 algorithm is in the public domain, and there are several
programs available that implement it. The algorithm is documented
in RFC 1321, which is available from many archives including
the "/rfc" directory in the anonymous FTP archive at ds.internic.net.
RFC 1321 itself includes source code for implementing the algorithm.
For convenience, that source has been extracted and made available
for anonymous FTP on info.cert.org in the "pub/tools/md5" directory.
2. Run the "md5check" program listed in Appendix A of this advisory.
This program will check a number of system files and note for
each one whether the checksum did or did not match the checksum
of a legitimate version.
If the checksum does match, you can be confident that particular
file has not been modified by an intruder. Note this does not mean
the file is the most recent version for your system - only that
it was in fact distributed by Sun.
If the checksum DOES NOT match, consider these possible reasons:
1) The file may be legitimate but not included in this database.
(Remember, the database is not complete.) To check this
possibility, compare the file against the original distribution
media. You may want to add the correct checksum to your copy
of the database.
2) You may have made local modifications to the file at your site.
To check this possibility, compare the file to a known good
version. You may want to add the correct checksum to your copy
of the database.
3) The file may be a Trojan horse installed by an intruder.
We encourage you to replace this file with a known good version,
and check for additional signs of compromise.

Appendix A: "md5check"
The following program is a "nawk" script that can be run against
the list of checksums "md5_sun.v1" in Appendix B:
% nawk -f md5check md5_sun.v1
This program along with a man page and the database below,
are available by anonymous FTP from info.cert.org in the
"pub/tools/md5check" directory.

##
## PLEASE NOTE: The entries included in this table do not represent complete
## coverage of all released versions of these files.
## In particular, checksum data for outdated patch releases is
## limited.
##
## Failure to match a checksum for a given file does not
## necessarily indicate the presence of a Trojan binary.
## Failure indicates that the file's checksum did not match any
## contained in this table. The file's authenticity should be
## verified against distribution media or local modifications.
##
## Success at matching a file's checksum indicates that the
## corresponding file is free from tampering.

Revision history
Aug. 30, 1996 Information previously in the README was inserted
into the advisory. Updated URL format.
Sep. 18, 1995 Intro. and Appendix B - Added note about checking with
vendors for current checksum values.
(as received) Appendix B, Hewlett-Packard & Solbourne - added checksums
Sun - corrected one line of Sun entry:
"md5:SunOS:4.1.3_u1:Original Dist:sun4:/usr/bin/login"
is now "md5:SunOS:4.1.3_u1:Original
Dist:sun4:bin/login" and has a new checksum
Sept. 18, 1995 - Intro. - Updated the URL for Tripwire.
