i have list of IPs where is probably hosted an malware

IP - path to malware on that machine

i want to ask how i can bulk email the IP owners in aim to notiffy them about infection?

I know i can create an Linux bash script to extract administrator email out of whois.. but i would like to ask anyone to share his idea or how to complete that script?

my script idea:


for ip in $(cat $ips);do
whoisout="$(whois $ip)"
emails="$(echo "$whoisout" | grep @)"

then somehow extract email address and send email:

echo "Hello, an computer with Your IP $ip , is probably infected by malware. The malware path \"$path\".
Please kindly contact IP owner to remove this malware and install antivirus system." | mail -s "Malware on Your IP" $ipemail
