1. What was the cause of the first Internet Worm? In specific, what vulnerabilities did the worm take advantage of in order to spread through the Internet?

The worm used the known access loopholes in order to propagate over networks. It relied on implementation errors in two network programs: sendmail and fingerd.
2.Are those vulnerabilities still present?
The vulnerabilities were patched.
