Why did the call from 02 8359 9864 hang up when I answered?
Silent calls that disconnect immediately when answered are typically generated by automated systems. These calls often test whether a phone number is active and monitored.

Is 02 8359 9864 a scam or just nuisance?

What should I do if 02 8359 9864 calls me again?
If 0283599864 calls repeatedly, block the number immediately in your phone's settings. Monitor for follow-up calls from similar or different numbers within the next 24-48 hours.

Can silent calls from 02 8359 9864 be dangerous?

The danger comes from the validation that precedes more targeted attacks.
