My outlook email account was hacked . I opened an email from a known contact that asked me to log in which I stupidly did without thinking and listed my email account and password. to open the site. When I realized what I had done  I changed my password ASAP  which took a few minutes. I am using a MAC platform.. I sent the hackers address to Outlook. What should I do now ? Should I notify all my contacts to be on the alert for SPAM?  What will the hackers do with this information? Should I close this account?
