Optus: How a massive data breach has exposed Australia
Last week, Australian telecommunications giant Optus revealed about 10 million customers - about 40% of the population - had personal data stolen in what it calls a cyber-attack.
Some experts say it may be the worst data breach in Australia's history.
But this week has seen more dramatic and messy developments - including ransom threats, tense public exchanges and scrutiny over whether this constituted a "hack" at all.
It's also ignited critical questions about how Australia handles data and privacy.
Anger rises after 40% of Australians had details stolen in possibly the nation's worst-ever breach.
