LinkedIn users who have received email messages claiming that they need to do some activity on their accounts, such always go directly to www.linkedin.com and sign into their accounts. Once they have signed in, they will be notified of security updates, notifications and other important notifications. So, there is no need to click on a link in an email message, which may go to phishing or malicious website.
Also, LinkedIn users who have already been tricked by the phishing LinkedIn email messages, are asked to change their LinkedIn passwords immediately before their accounts are hijacked and used fraudulently by cybercriminals.
