Paypal users should always go directly to www.paypal.com and sign into their accounts when they receive email notifications, instead of clicking on the links in the same email notification. Once they have sign-in, they will be notified of changes or updates. Doing this will prevent PayPal users from becoming victims of phishing scams.
PayPal users who have been tricked by the phishing scam, should change their passwords immediately and check their accounts for discrepancies, and report those discrepancies (if there is any) to PayPal.
