# PoodleWalk SSLv3 Scanner v20141017 by 1N3
# http://treadstonesecurity.blogspot.ca
# Usage: ./poodlewalk.sh <CIDR|IP>
#
# ABOUT:
# PoodWalk makes it easier to mass scan environments for systems vulnerable to the "Poodle" vulnerability. It uses unicorn scan to scan a large range of IP's or CIDR blocks for port 443. If open, poodwalk runs SSLScan for SSLv3 enabled ciphers which are vulnerable to the "Poodle" attack in CVE-2014-3566.
#
# REQUIREMENTS:
# Is unicornscan installed?
# Is sslscan installed?
#
# USAGE EXAMPLES:
# ./poodlewalk.sh 192.168.0.0/16 - Mass scan all hosts for port 443 and test for SSLv3 on 192.168.0.0/16
# for a in `cat my_list_of_domains_or_ips.txt`; do ./poodlewalk.sh $a; done; - Mass scan a text file of domains and IP's for Poodle
