Telstra Impersonation Reports for 03 9003 1144

Two contributors have reported calls from 03 9003 1144 (also written as 0390031144) involving Telstra impersonation. Both reports describe callers claiming urgent security concerns with the recipient's internet connection, then attempting to gain remote access and extract sensitive information.

The pattern is consistent across reports about 0390031144: callers establish false urgency by referencing security threats, then manoeuvre contributors toward granting access or sharing credentials. This is a recognisable tech support scam tactic where fraudsters exploit trust in the Telstra brand.

What Callers from 03 9003 1144 Say

One contributor reported that the caller from 03 9003 1144 claimed the recipient's internet was not secure and offered to connect them to a "secure server" to resolve the issue. This is a social engineering technique designed to lower the recipient's guard.

The second report about 0390031144 provides more detail on the escalation: after establishing the false security premise, the caller requested IP address information, asked for remote access credentials, and requested passwords and financial information. Contributors described the caller's approach as pushy once personal details were requested.

Report Patterns and Behaviour

Both reports of calls from 03 9003 1144 came from answered calls rather than voicemails, suggesting the scammers rely on real-time manipulation. The timing between reports (February to March 2026) indicates this number may be actively used in an ongoing campaign.

Contributors noted that callers from 0390031144 did not identify themselves with a specific name or department within Telstra, relying instead on the company name and vague references to security systems to appear legitimate.

What to Do If You Receive a Call from 03 9003 1144
