Tech Support Impersonation Reports for 03 9022 1845

Four contributors have reported suspicious activity from 03 9022 1845 (also written as 0390221845), a Melbourne-based NETSIP service landline. The most alarming report involves a caller impersonating Telstra, claiming the recipient's internet had a public IP address vulnerable to scammers. One contributor recognised the deception immediately, noting they weren't even a Telstra customer, and challenged the caller who then hung up. This pattern aligns with tech support scams where callers use technical-sounding language to create false urgency and extract access to devices or personal information.

Beyond the Telstra impersonation, 0390221845 has also been flagged for callback-lure tactics. A contributor received an unsolicited call from this number with no message left, and when they attempted to return the call, no one answered. This behaviour is characteristic of callback scams where the goal is to trigger return calls that may connect to premium numbers or malicious IVR systems.

What Callers from 03 9022 1845 Do

Contributors describe distinctly different tactics from this number. In the most serious incident, the caller posed as a Telstra representative and claimed the recipient's internet connection exposed them to scammer risk due to a public IP address. This is a classic social engineering approach designed to bypass scepticism by framing the scam as a security warning.

Other callers from 03 9022 1845 exhibit abusive and disruptive behaviour. One contributor received a voicemail containing only swearing and abuse with no intelligible message. Another answered a call from this number only to hear background noise and then be hung up on immediately. These patterns suggest either automated callback testing, intentionally harassing callers, or systems cycling through large contact lists with minimal interaction.

Call Patterns and Timing

Reports span late evening and overnight periods, with calls recorded on 9 June at 20:48 and 01:49, and again on 8 June at 21:37. One unsolicited call was registered on 10 June at 09:44. The voicemail containing abuse was left in the early morning (01:49), and the Telstra impersonation call came during evening hours (21:37). This timing pattern suggests callers may be targeting recipients when they're less likely to verify claims thoroughly.

The callback-lure incident involved an unanswered call with no voicemail, designed to prompt curiosity-driven return calls. When the contributor called back 0390221845, no one answered, confirming the lure nature of the initial contact.

What to Do If You Receive a Call from 03 9022 1845

• Do: Hang up immediately and verify any claims by calling the company directly using an official number from their website
