Just used Zapier to set up a RSS-to-email trigger to get notified about things like this in the future, although Amazon really should be sending them out automatically to customers.
AWS's ELB (which we use) were vulnerable, we'll be replacing certificates ASAP. We (and most the rest of the internet using ELB) seem to be in the clear now:
./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?
https://aws.amazon.com/security/security-bulletins/heartblee...
Wonder where this is even linked from?
