Identity Theft

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.

Optus - a subsidiary of Singapore Telecommunications Ltd - went public with The Breach About 24 hours after it noticed suspicious activity on its network.

Australia's second biggest telecoms provider said current and former customers' Data was Stolen - including names, birthdates, phone numbers, email addresses, passport numbers and Driving Licence numbers. It stressed that payment Details and account passwords were not compromised.

Those whose passport or licence numbers were Taken - roughly 2. 8 million People - are at a " quite significant" risk of Identity Theft and fraud, the Government has since said.

Optus said it was investigating The Breach and had notified police, financial institutions, and Government regulators. The Breach appears to have originated overseas, local media reported.

In an emotional apology, Optus chief executive Kelly Bayer Rosmarin called it a " sophisticated attack" Saying The Company has very strong cybersecurity.

" Obviously, I Am angry that there are People Out There that want to do this to our customers, and I'm disappointed that we couldn't have prevented it, " She Said on Friday.

Early on Saturday, an internet user published Data samples on an online forum and demanded a Ransom of $1m (A$1. 5m; £938,000) in cryptocurrency from Optus.

The Company had a week to pay or The Other Stolen Data would be sold off in batches, the person said.

Investigators are yet to verify the user's claims, but some experts quickly said the sample Data - which contained About 100 records - appeared legitimate.

Sydney-based tech reporter Jeremy Kirk contacted the purported hacker and said the person gave him a detailed explanation of how they stole the Data .

The user contradicted Optus's claims The Breach was " sophisticated" Saying they puled the Data from a freely accessible software interface.

" No authenticate needed… All open to internet for any one to use, " they said in a message, according to Kirk.

In another escalation on Tuesday, the person claiming to be The Hacker released 10,000 customer records and reiterated the Ransom deadline.

But just hours later, the user apologised - Saying it had been a " mistake" - and deleted the previously posted Data sets.

" Too many eyes. We will not sale [sic] Data to anyone, " they posted. " Deepest apology to Optus for this. Hope all goes well from this. "

That sparked speculation About whether Optus had paid the Ransom - which The Company denies.

Adding to The Problem , others on The Forum had copied the now-deleted Data sets, and continued to distribute them.

It also emerged some customers' Medicare Details - Government identification numbers that could provide access to medical records - had also been Stolen , something Optus did not previously disclose.

Late on Wednesday, The Company said this had affected almost 37,000 Medicare cards.

Optus has been inundated with messages from angry customers since last week.

People have been warned to Watch Out for signs of Identity Theft and for opportunistic scammers, who are said to be already Cashing In on The Confusion .

A class-action lawsuit could soon be filed against The Company . " This is potentially The Most serious privacy breach in Australian history, both in terms of The Number of affected People and the nature of The Information disclosed, " said Ben Zocco from Slater and Gordon Lawyers.

The Government has called The Breach " unprecedented" and blamed Optus, Saying it " effectively left The Window open" for sensitive Data to be Stolen .

In an ABC television interview on Monday, Cyber Security Minister Clare O'Neil was asked: " You certainly don't seem to be buying The Line from Optus that This Was a sophisticated attack? "

" Well, it wasn't. So no, " Ms O'Neil replied. The Moment drew lots of attention online.

Ms Bayer Rosmarin told News Corp Australia on Tuesday: " We have multiple layers of protection. So it is not the case of having some sort of completely exposed APIs [software interfaces] sitting Out There .

" I think most customers understand that We Are not the villains, " She Said , adding Optus could not say more while The Investigation was ongoing.

The Company has faced calls to cover the costs of replacement passport and driving licences, as People scramble to protect themselves.

The Breach highlights how much Australia lags other parts of The World on privacy and cyber issues, Ms O'Neil says.

" We Are probably a decade behind… where we ought to be, " she told the ABC.

Both sides of politics have traded blame on the issue. Opposition MPs have said the Labor Government is " asleep at the wheel" but the Government points out it was only elected in May after a decade of conservative rule.

Ms O'Neil pointed to two areas needing urgent reform.

She argues the Government should be able to better penalise companies like Optus. In some countries, The Company would have faced hundreds of millions of dollars in penaltiesbut Australia's fine is capped at About $2m, She Said .

She also wants to expand cyber-security laws that were introduced Last Year to include telecommunications companies.

" At The Time , the telecommunications sector said: " Don't worry About Us - we're really good at cybersecurity. We'll do it without being regulated. I would say that this incident really calls that assertion into question. "

Security experts have also suggested reforming Data retention laws so telecommunication companies don't have to keep sensitive information for so long. Ex-customers should also The Right to request companies delete their Data , experts say.

Optus says it is required to keep identity Data for Six Years under the current rules.

Other industry figures have argued consumers should be able to take companies that lose control of their information to court, instead of the industry regulator.
