\n
\n

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.<\/b><\/p>\n<\/div>\n<\/div>\n

\n
\n

Some experts say it may be the worst data breach in Australia’s history.<\/p>\n<\/div>\n<\/div>\n

\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
\n

It’s also ignited critical questions about how Australia handles data and privacy.<\/p>\n<\/div>\n<\/div>\n

\n

The alarm was sounded last Thursday<\/span><\/h2>\n<\/div>\n
\n
\n

Optus – a subsidiary of Singapore Telecommunications Ltd – went public with the breach about 24 hours after it noticed suspicious activity on its network.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Australia’s second-largest telecoms provider said current and former customers’ data was stolen – including names, birthdates, home addresses, phone and email contacts, and passport and driving licence numbers. It stressed that payment details and account passwords were not compromised.<\/p>\n<\/div>\n<\/div>\n

\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
\n

In an emotional apology, Optus chief executive Kelly Bayer Rosmarin called it a “sophisticated attack”, saying the company has very strong cybersecurity.<\/p>\n<\/div>\n<\/div>\n

\n
\n

 <\/p>\n

“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.<\/p>\n<\/div>\n<\/div>\n

\n

Then a ransom threat was made<\/span><\/h2>\n<\/div>\n
\n
\n

Early on Saturday, an internet user published data samples on an online forum and demanded a ransom of $1m (A$1.5m; \u00a3938,000) in cryptocurrency from Optus.<\/p>\n<\/div>\n<\/div>\n

\n
\n

The company had a week to pay or the other stolen data would be sold off in batches, the person said.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Investigators are yet to verify the user’s claims, but some experts quickly said the sample data – which contained about 100 records – appeared legitimate.<\/p>\n<\/div>\n<\/div>\n

\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
\n

The user contradicted Optus’s claims the breach was “sophisticated”, saying they pulled the data from a freely accessible software interface.<\/p>\n<\/div>\n<\/div>\n

\n
\n

“No authenticate needed\u2026 All open to internet for any one to use,” they said in a message, according to Kirk.<\/p>\n<\/div>\n<\/div>\n

\n

As data circulates, revelations of more stolen details<\/span><\/h2>\n<\/div>\n
\n
\n

In another escalation on Tuesday, the person claiming to be the hacker released 10,000 customer records and reiterated the ransom deadline.<\/p>\n<\/div>\n<\/div>\n

\n
\n

But just hours later, the user apologised – saying it had been a “mistake” – and deleted the previously posted data sets.<\/p>\n<\/div>\n<\/div>\n

\n
\n

“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.”<\/p>\n<\/div>\n<\/div>\n

\n
\n

That sparked speculation about whether Optus had paid the ransom – which the company denies – or whether the user had been spooked by the police investigation.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Adding to the problem, others on the forum had copied the now-deleted data sets, and continued to distribute them.<\/p>\n<\/div>\n<\/div>\n

\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Late on Wednesday, the company said this had affected almost 37,000 Medicare cards.<\/p>\n<\/div>\n<\/div>\n

\n

‘Potentially Australia’s most serious breach’<\/span><\/h2>\n<\/div>\n
\n
\n

Optus has been inundated with messages from angry customers since last week.<\/p>\n<\/div>\n<\/div>\n

\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
\n

The government has called the breach “unprecedented” and blamed Optus, saying it “effectively left the window open” for sensitive data to be stolen.<\/p>\n<\/div>\n<\/div>\n

\n
\n

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?”<\/p>\n<\/div>\n<\/div>\n

\n
\n

“Well, it wasn’t. So no,” Ms O’Neil replied. The moment drew lots of attention online.<\/p>\n<\/div>\n<\/div>\n

\n

What happened at Optus wasn’t a sophisticated attack.<\/p>\n

We should not have a telecommunications provider in this country that has effectively left the window open for data of this nature to be stolen.#abc730<\/a> pic.twitter.com\/KamkiapcZl<\/a><\/p>\n
