bank scam, sms sent to 1000s of people claiming that their cards have been blocked due to security reasons, then they ask you to fill out a form which is linked to their accounts. This scam only starts when you use your paypal

Message received from this number: "We regret to inform you that your NAB card is now locked. To unlock please update security details at http://www.nabmobile.link". If you click the link, takes me to NAB login page but it's not the NAB, it's a phishing page
