Then I run bellow verify command :

#rpm -qfV /bin/bash
prelink: /bin/bash: at least one of file’s dependencies has changed since prelinking
S.?…..    /bin/bash

I had never seen this before, but apparently rpm is doing something different now that prelink is present. Note that the ‘5′ was replaced by ‘?’ which I take to mean that RPM doesn’t know if the checksum matches or not.

No, there was no hacking attempt . you just have to run /etc/cron.daily/prelink, and when that’s done, no more binary files issues.
