i received a waring from rkhunter:

Warning: The file properties have changed:
         File: /usr/bin/wget
         Current hash: 2d5d175c449eecfda43401a7a66b8a369859524d
         Stored hash : 1725543768f7e1b2a32136ca1799213a8bdb886b

  You've applied a security update, which has changed
 the binary /usr/bin/wget.

  The alert is telling you that the binary has changed,
 and since this is expected (because you've applied the security update)
 the alert is informational not a real report.

Depends. Did you upgrade wget? In this case it's normal (even  
expected) that the file changes.

There was a security update for wget recently.

It's normal that the hash change after an upgrade.
Take a look at
,----[ /usr/share/doc/rkhunter/README.Debian ]-
| * HASH CHECKS
|   By default, all hashes checks are now ENABLED in the standard daily cron
|   job.
|
|   Add the 'hashes' and 'attributes' tests to the DISABLED_TESTS option in
|   /etc/rkhunter.conf if you wish to disable them.
|
|   If enabled, each time a base package is upgraded, you will have to run:
|   'rkhunter --propupd' to update the file properties database located
|   in /var/lib/rkhunter/db/rkhunter.dat.
|
|   This can be done automatically after each install/remove. Please run:
|     # dpkg-reconfigure rkhunter
|   to enable this feature.

You may want to update rkhunter's data file to prevent this exact alert from
showing up in the future (rkhunter --propupd).
