NAB Bank Impersonation SMS Scam Using 03 5077 3258

A contributor has reported receiving an SMS impersonating NAB bank that claims someone attempted to access their account using a Samsung phone at a specific time. The message directs the recipient to call 03 5077 3258 (also written as 0350773258) to speak with customer service. The contributor correctly identified that this is not a legitimate NAB contact number and flagged it as a phishing scam.

This type of SMS scam exploiting banking credentials is particularly dangerous because it creates false urgency around account security. The attacker relies on the victim calling the number in the message, where they would likely be asked to verify personal details, banking credentials, or one-time passwords under the guise of confirming account access.

How NAB Impersonation Scams Work

The SMS from 03 5077 3258 follows a common pattern used in banking impersonation scams. The message references a specific device (Samsung phone) and timestamp to make the alert feel credible and personalised. It then instructs the recipient to call what appears to be customer service but is actually a scammer's number. Once called, victims are typically asked security questions, account numbers, or PIN codes under the pretence of verifying unauthorised access.

NAB bank has legitimate customer service numbers published on their official website. If you receive an alert about your NAB account, you should never call a number provided in an unsolicited SMS or email. Instead, call NAB directly using the number on your bank statement or the official NAB website.

Report Details and Contributor Alert

The contributor who received the SMS from 0350773258 recognised several red flags that helped identify it as a scam. They noted that NAB has direct customer service numbers that are well-known to customers, and the number 03 5077 3258 is not one of them. This awareness likely prevented them from calling the scam line and compromising their banking information.

The SMS included specific details (device type and time of attempted access) that were designed to bypass the victim's initial skepticism. This level of personalisation is common in sophisticated phishing scams that harvest contact lists or personal data from data breaches.

What to Do If You Receive an SMS from 03 5077 3258

If you receive an SMS from 03 5077 3258 or similar messages claiming to be from NAB or other banks:
