Why did a scam text appear in my real NAB SMS thread?

Scammers use a technique called 'Sender ID Spoofing' to make their messages appear under the name 'NAB', grouping them with your genuine texts.

What should I do if I clicked a fake NAB link?

If you entered your login details or banking info, contact NAB immediately at 13 22 65 (their official number) and lock your cards via the NAB app.

How do I check if a transaction is real?

Open the official NAB app on your phone or go directly to nab.com.au on your computer. Log in normally and review your transaction history.

Detecting fake NAB alerts

NAB communicates differently from scammers. Watch out for these aggressive tactics designed to steal your bank login and one-time passwords (OTP).

Claims your account has been locked

A common lure to create panic. The message will include a link to a fake NAB login page to 'verify' your identity.

Alerts of a fake 'unusual transaction'

Messages claiming a large payment was made or a 'new payee' was added, prompting you to call a fake fraud team number.

Emails from non-official addresses

Real NAB emails will only ever come from an @nab.com.au address. Scammers often use slightly altered domains or free email providers.

Requests your One-Time Password (OTP)

NAB will never ask you to read out or forward a security code/OTP. If someone asks for it, they are a scammer.

What IsThisSpam checks before you trust a sender

Quick verdicts are useful, but the real value is understanding why something looks safe, uncertain, or risky.

Links leading to login screens

Never click a link in an SMS or email to securely log in to your bank account. Always use the official NAB app.

Pressure-driven decision framing

Scam messages force immediate action to prevent you from verifying the claim independently.

Spoofed Sender IDs

Even if the SMS says it's from 'NAB' and appears in your regular NAB thread, it can still be a scam.

Fake fraud department calls

Scammers will call you pretending to be the NAB fraud team, asking you to transfer money to a 'safe account'.
