Great idea, I just setup an RSS-to-slack trigger for future notifications: http://zpr.io/HSkn
It detects new AWS security bulletin items and notifies you via Google Hangout.
./heartbleeder zapier.com
VULNERABLE - zapier.com:443 has the heartbeat extension enabled and is vulnerable to CVE-2014-0160
./heartbleeder zapier.com
SECURE - zapier.com:443 has the heartbeat extension enabled, but timed out after a malformed heartbeat (this likely means that it is not vulnerable)
When did you run your check? Do you have a recent binary of heartbleeder?
