Telstra Impersonation Reports for 03 9003 1139

Six contributors have reported calls from 03 9003 1139 (also written as 0390031139), with a notable pattern of callers impersonating Telstra. Two reports specifically describe callers claiming to represent Telstra Cyber Security or Telstra services, despite contributors having no active accounts with the provider. One contributor reported that the caller knew their full name and maiden name, yet was asking about a Telstra service the recipient hadn't held for 20 years, suggesting the scammer was using outdated personal data harvested from a breach or database.

The caller's knowledge of personal information combined with a false Telstra affiliation creates a high-risk impersonation attempt. When confronted, one caller immediately hung up. Another report mentions the caller's voice quality was notably poor with "crackly and sketchy" audio, a common indicator of spoofed or compromised calling infrastructure.
