NAB Customers Targeted in new Phishing Email Scam

Posted by MailGuard on 13 January 2022 16:31:59 AEDT

National Australia Bank (NAB) has once again been impersonated by cybercriminals in a phishing email scam designed to steal users’ confidential data.


Customers should be wary of an email titled “Please review your account” claiming that their debit card has been blocked.


Intercepted by MailGuard, this new phishing scam advises customers that their “debit card has been temporarily blocked” and that “online payments and cash withdrawals can’t be made until the issue is resolved.” To create a sense of urgency, the email also asks to “confirm your details within the next 48 hours.”


Sent from “NAB”, the sender name is spoofing National Australia Bank with the actual sender address of “oren(at)orentzo(dot)co(dot)il”, and an email subject reading, “Please review your account”.


In this case the scammers have added a degree of sophistication by varying the sender email addresses. Using different SendGrid email addresses i.e. airmaster(dot)com(dot)au(at)sendgrid(dot)net or lynchgroup(dot)com(dot)au(at)sendgrid(dot)net, the scammers aim to avoid being be blocked by email security services.


Here’s what the email looks like: 



When a customer clicks on the “Confirm” link, they are taken to a login page (pictured below) that requests their “NAB ID” and ‘Password’. The suspicious looking phishing page is hosted at https://dynamosinvestigators(dot)com(dot)ng.


Once these details have been submitted, users are taken to a page asking to “Confirm your identity” by entering full name and debit card details.  



Following this, users are directed to a page titled “Billing Details” requesting their address and phone number.


Next, users are taken to an SMS verification page. The page asks for a ‘PIN’ which has been sent to the mobile phone number provided, mimicking an authentic OTP security process. This technique is often used by cybercriminals to feign authenticity.  




The final step in the scam, is a ‘Thank You!’ page claiming that “Your card is now unlocked” and can be used anywhere.


Financial institutions are always a popular target for scammers, their trusted brands and large customer bases make them an appealing target. Earlier this month MailGuard blocked and reported a similar scam impersonating BOQ.


As you can see from the screenshots above, cybercriminals have taken great pains to replicate official landing pages from NAB – including incorporating the bank’s branding and logo using high-quality graphical elements in the phishing pages. All this is done to trick users into thinking the scam is legitimate.


However, there are many red flags in the email including the “from” address not matching NAB’s domain name and the address in the email footer is not an Australian address, where NAB is based.


If you suspect that you have received a scam email pretending to be from NAB, the bank suggests forwarding it to


They advise that"NAB will never suspend your account or send you a link to verify your identity”.
