Could someone tell me what this is please.

From my experience this is a malicious script that has been added to cron in order to restart at different times.

I recommend looking at the file to see what it's doing, as this is most likely some type of remote shell script.

 

Appears to be doing some checks on the timezone. No reason to be worried about hat script. It doesn't appear to be doing anything harmful.

 

hi,

you can use something like this for naughty cron stuff

Code:

#!/bin/sh
myemail=$1
if [ -n "$myemail" ] ; then
        mycrontmp=/root/cron.tmp.$$
        # get current user list
        for i in `cat /etc/passwd | cut -f1 -d ':' | grep -v '#'`; do
                echo "--------------------------------------------------"
                echo "Username: ${i}"
                echo "--------------------------------------------------"
                crontab -u ${i} -l 2>&1
                echo "--------------------------------------------------"
        done > $mycrontmp
        cat $mycrontmp | mail -s "crontab report for `hostname`" ${myemail}
        rm -f $mycrontmp
else
        echo "Please supply a valid email address to get the report."
        exit
fi

chmod 755 scriptname.sh
usage ./scriptname.sh you@mail.com

it will show you the cronjobs from all accounts on the server so you can do something if you find anything naughty
