Suspicious Personal Information Request from 03 9021 1579
A contributor has reported receiving suspicious calls from 03 9021 1579 (also written as 0390211579) at their workplace. The caller initially rang the contributor's mobile phone twice while they were working, then followed up by calling their work phone directly. When questioned about the initial call, the caller denied making it, which raised immediate red flags for the recipient.
The caller claimed to have obtained the work phone number from a colleague whose name the contributor did not recognise. During the conversation, the caller discussed Palo Alto products and systems, but the overall pattern of contact and explanation seemed suspicious to the recipient. The unsolicited nature of the calls, combined with the unclear sourcing of contact information and denial of the initial contact attempt, suggested potential social engineering.
What to Do If You Receive a Call from 03 9021 1579
If 0390211579 calls you:
- Do not: Confirm personal details, employee information, or system access details; answer if you don't recognise the number; return the call to a number they provide
- Do: Let unknown calls go to voicemail; verify the caller's identity through official company channels before discussing any work systems or colleagues; block the number if calls continue
- Do: Report the incident to your IT security or compliance team, as social engineering targeting workplace systems is a security concern

WRITE A REVIEWFrequently Asked Questions
Why did the caller from 03 9021 1579 deny making the first call?
Denial of initial contact is a common social engineering tactic. By appearing to distance themselves from the first attempt, the caller may be testing your response or attempting to seem more legitimate. The fact that 0390211579 still proceeded with the second call to your work phone suggests the contact was deliberate, not a mistake.
How might a caller obtain my work phone number?
The caller claimed to have received your work number from a colleague you don't recognise. This could indicate the caller researched your company, purchased contact lists, or obtained information through social engineering of other employees. Always verify the source of any unsolicited caller's information through your company's official channels before confirming details.
Should I be concerned about calls discussing Palo Alto products?
Legitimate vendors and partners do reach out to businesses about security products like Palo Alto. However, the pattern reported from 03 9021 1579 - unsolicited multi-channel contact, denial of previous calls, and unclear sourcing of your information - suggests this may not be a legitimate vendor. Always verify caller identity through your company's official procurement or IT department.
What is social engineering and why should I report it?
Social engineering is when someone uses manipulation or deception to extract sensitive information. A call from 03 9021 1579 (0390211579) that targets your workplace systems or colleague information is a security threat. Report it to your IT team and cyber.gov.au so authorities can investigate and prevent similar attacks on other organisations.
Is 0390211579 a legitimate business number?
The number 03 9021 1579 is allocated as a local service through Symbio Networks in Victoria. However, allocation data alone does not confirm legitimacy. The contributor's report indicates suspicious behaviour regardless of the number's technical allocation. Verify any unsolicited caller's identity independently.
What should I do if I already gave information to a caller from 03 9021 1579?
If you shared any work system access details, employee names, or internal information with a caller from 0390211579, notify your IT security team immediately. They can review system logs, reset credentials if necessary, and monitor for unauthorised access. For general personal information, monitor your accounts for suspicious activity and consider updating passwords.
