Things we need to ask ourselves. Is this system at the end of it's life? If it is we can check if it is vulnerable to heartbleed. In this case, this machine uses ubuntu precise which was last updated in 2014. We might be able to find if it is vulnerable to heartbleed. Since it is an older machine we can run a vulnerability script with the following command to check for vulnerabilities.

nmap --script vuln -oA vulnscan 10.10.10.79

We can also confirm thatvulnerable to heartbleed by running sslyze. 

sslyze --heartbleed 10.10.10.79:443
