Hint 1: Generally, all files that aren't intended to be changed by a normal user can be considered worth watching. Think configuration files and bin directories.
Hint 2: A good indication of change can be found by using cryptographic hashing functions
Hint 3: A Tripwire can tell you when something is happening.

Yes, I'm being sketchy on purpose Smilie

TWINTRO(8)						      System Manager's Manual							TWINTRO(8)

NAME
twintro - introduction to Tripwire software DESCRIPTION
Tripwire 2.4 is a file integrity assessment product for Linux networks. Rather than preventing an intruder or virus from attacking system files, Tripwire detects intrusions when they do occur. By comparing system files and directories against a previously stored "baseline" database, Tripwire finds any additions, deletions, or changes to specified properties. This allows the system administrator to determine the extent of the problem and begin necessary damage control. After Tripwire is installed on a system, the following four commands are used: tripwire(8) is used for most of the basic operations of the software. This includes creation of the Tripwire database, and checking the integrity of the filesystem against that database. twadmin(8) is used to create, encode, and sign Tripwire policy, configuration, and key files, and for various administrative functions. twprint(8) prints Tripwire database and report files in a plain text format. siggen(8) is a file utility that displays hash values for files. In addition to the command references listed above, the following three man pages provide information on important components of the Trip- wire package. twfiles(5) provides an overview of the various files created and used by Tripwire, including default locations and settings. twconfig(4) explains the configuration file, which is used to set system-specific information that affects Tripwire operation. twpolicy(4) explains the policy file, which specifies the files and directories Tripwire should check, and how they should be scanned. Using the --help flag with any Tripwire command (e.g. tripwire --help) will print a short summary of the command modes for that command. If a mode selector is also specified (e.g. tripwire --check --help), a mode-specific usage message will be displayed. Using the all argu- ment with the --help flag (e.g. tripwire --help all) will print detailed usage messages for all modes of the specified command. VERSION INFORMATION
