Ctime of binary files have changed

Solution Verified - Updated -


  • The ctime of seemingly random binary files changes on a regular basis. If third-party security monitoring software such as tripwire is used to monitor binary files, it will report files operated on by the prelink command as having been changed, thus requiring follow-up auditing to determine the cause.

  • Examples:

[root@server ~]# ls -l /sbin/mount.vmhgfs
-r-xr-xr-x 1 root root 57736 Jun  6 19:02 /sbin/mount.vmhgfs
[root@server ~]# ls -lc /sbin/mount.vmhgfs
-r-xr-xr-x 1 root root 57736 Jun 13 03:29 /sbin/mount.vmhgfs


[root@rhel01 ~]# stat /usr/bin/pr
