Blackmail Threat Reports for 04 3470 5424

One contributor has reported receiving blackmail SMS messages from 04 3470 5424 (also written as 0434705424).

Report Patterns and Timing

The report was submitted in April 2026, with the SMS channel indicating the scammer relied on text-based contact rather than voice calls. The fact that a second message was sent after the recipient ignored the first suggests the scammer had the number on a list and was working through multiple potential targets with a standard extortion script.

Scammers send the same threatening message to thousands of numbers, knowing a small percentage of recipients will panic and respond. The follow-up message from 04 3470 5424 indicates this was likely an automated or semi-automated campaign targeting multiple recipients.
