Bank Impersonation Reports for 04 3423 0908
A contributor has reported receiving a call from 04 3423 0908 claiming to be from the Commonwealth Bank Verification Department. The caller knew the recipient by name but was attempting to extract personal information from someone with no account at that institution. This report on 0434230908 suggests a phishing attempt using bank impersonation as the social engineering hook.
The call came from an Optus mobile number, making it a mobile-based bank impersonation attempt rather than a spoofed institutional line. One report is enough to flag 04 3423 0908 as suspicious when the caller falsely identifies as a major Australian bank.
What the Caller from 04 3423 0908 Did
The contributor described the interaction as a phishing attempt. The caller addressed them by name and claimed to be calling from Commonwealth Bank's Verification Department. The key red flag was the caller requesting personal information while the recipient does not actually hold an account with that bank. This mismatch between the false institution and the target's actual banking relationships is a hallmark of mass phishing campaigns where scammers cold-call numbers hoping to find customers of the impersonated bank.
The caller's knowledge of the recipient's name suggests the number may have come from a purchased or scraped contact list, though the lack of banking details indicates the scammer was working from incomplete data about 0434230908's target.

WRITE A REVIEWFrequently Asked Questions
Why did the caller from 04 3423 0908 know my name if they didn't know my banking details?
Scammers using bank impersonation often source contact lists with names and phone numbers from data brokers or leaked databases. They then cold-call these numbers claiming to be from a major bank, hoping some recipients are actual customers. The contributor's experience with 0434230908 shows the caller had partial information (name) but was missing banking details, indicating a mass phishing campaign targeting multiple numbers at once.
Should I call Commonwealth Bank back to verify if 04 3423 0908 was legitimate?
No. Never call a number provided by the caller claiming to be your bank. Instead, hang up, find the official number for Commonwealth Bank on your card or bank statement, and call them directly using that verified number. The caller from 04 3423 0908 was not legitimate, so do not attempt to reconnect with them.
What personal information was the caller from 0434230908 trying to get?
The contributor reported the caller was requesting personal information but did not specify exactly which details. In typical bank impersonation scams, callers from numbers like 0434230908 attempt to obtain account numbers, PINs, passwords, security answers, or one-time verification codes. Never provide any of these to an unexpected caller.
Is 04 3423 0908 a real Commonwealth Bank number?
No. Commonwealth Bank does not call customers from random mobile numbers like 04 3423 0908 requesting personal information or verification. The number 0434230908 is registered to an Optus mobile account and was used by a scammer impersonating the bank.
