NAB Impersonation SMS Scam from 918303885913

A contributor received an SMS from 918303885913 on 21 October 2026 impersonating the National Australia Bank (NAB) with a fake security alert. The message claimed a Western Union transfer of $450.00 had been attempted on the recipient's account and requested immediate callback to verify the transaction.

This is a classic impersonation scam targeting Australian banking customers. The SMS from 918303885913 uses urgent language and financial alarm to pressure recipients into calling a fraudulent number embedded in the message. The scammer then attempts to extract banking credentials, security codes, or personal information under the guise of account verification.

What the SMS from 918303885913 Contains

The message received from 918303885913 reads: "NAB Security Notice: Your attempted Western Union transfer of $450.00" followed by instructions to call the provided number for verification.

The scam relies on several psychological triggers:

• Urgency: Framing an "attempted" transfer to suggest account compromise
• Authority: Impersonating NAB, a major trusted Australian bank
• Specificity: Mentioning an actual payment service (Western Union) and a plausible dollar amount
• Call-to-action: Requesting immediate callback to a number controlled by the scammer

The contributor noted this was the third scam attempt received within three days, indicating the phone number 918303885913 may be part of an active scam campaign.

Callback Number and Link Risks

• Card details and CVV security codes
• One-time passwords (OTPs) from your phone or authenticator app
• Personal identification information (date of birth, driver's license details)

Any information provided to this number will be used for fraud. The SMS from 918303885913 may also contain hidden links in shortened URLs or "click here to verify" prompts that direct to fake NAB login pages designed to capture credentials.
