Proper now, criminals can simply and cheaply purchase what seems to be entry to a stranger’s Commonwealth Checking account for simply $US50 on-line. All they should know is the right way to navigate the ‘darkish net’.
“Australian IP is required to log under consideration,” one commercial on a darkish net platform proven to this masthead reads. “Refunds and replacements are solely given if account username and password is inaccurate.”
The vendor on this occasion has 52 evaluations by different consumers validating the providers on provide, and tags the merchandise with search phrases like “fraud” and “cash”.
A number of extra clicks and NAB bank cards and ANZ financial institution statements declare to be up on the market. “This template is totally editable. And is ideal for identification and verification,” claims one other vendor, GoldApple, who has 4.5 stars and 324 evaluations.
The darkish net has been described as a parallel model of the web, or the web’s evil twin. It’s comparatively simple to entry utilizing particular software program, simply not by way of a conventional net browser. It’s a spot the place unlawful items are bought to nameless customers who usually pay utilizing bitcoin, the digital foreign money that can not be traced.
Every of Australia’s large 4 banks have a group of “menace hunters” who’re employed to skim the darkish net on the lookout for leaked buyer knowledge, bank cards or different financial institution merchandise – some faux, some actual.
The menace hunters additionally seek for private particulars of financial institution executives – data that may be purchased and utilized by hackers desirous to extort the financial institution for cash.
The Age and The Sydney Morning Herald have spoken to dozens of present and former insiders throughout the main banks’ cybersecurity groups. None could possibly be named as a result of they had been discussing delicate data and weren’t authorised to talk publicly.
‘If this was every other crime, folks can be demanding police motion… There can be folks petitioning parliament.’
Former head of the Australian Cyber Safety Centre, Alastair MacGibbon
What has emerged is a classy community of hackers, coders and builders engaged by the banks to battle an ever-growing menace.
Cyberattacks are a rising downside throughout the complete financial system, with malicious actors focusing on massive and small corporations from each business. Certainly, this masthead’s dad or mum firm 9 Leisure was the sufferer of a cyberattack this yr that considerably affected its operations for weeks.
Whereas the main banks have among the many best-resourced cybersecurity groups within the nation, in addition they take care of legacy pc programs and large workers numbers – creating vulnerabilities for malicious assaults.
The Reserve Financial institution of Australia warned this month a serious assault in opposition to the nation’s largest banks was inevitable because of the quickly rising variety of assaults, echoing earlier warnings from the prudential regulator.
Former adviser to prime minister Malcolm Turnbull and head of the Australian Cyber Safety Centre, Alastair MacGibbon, describes cybercrime as an “existential menace” to people and companies, with regulation enforcement asleep on the wheel.
“The quickest rising crime in opposition to people and enterprise and authorities companies on this nation is cyber crime,” says MacGibbon, who’s now chief technique officer at CyberCX, Australia’s largest non-public cybersecurity agency.
“It’s time for policing companies to be devoting the trouble required to be defending Australians. If this was every other crime, folks can be demanding police motion… There can be folks petitioning parliament.”
The large banks maintain round $1.2 trillion in deposits and are owed greater than $1.8 trillion in funding and residential mortgage debt. As such, a profitable assault in opposition to a serious lender has the potential to destabilise the nation’s complete monetary system.
So, what’s going on inside the massive banks’ cybersecurity groups? Who’s behind these assaults? And the way doubtless are they to be thwarted?
Crimson group all the time wins
There’s a saying in cybersecurity circles that the purple group all the time wins.
In cybersecurity operations contained in the banks, purple groups and blue groups are used to simulate situations to check the cyber defences. Crimson groups assault, blue groups defend.
If the purple group all the time wins, it means hackers can all the time crack a financial institution’s system to entry its crown jewels – buyer knowledge, money or mental property – regardless of how a lot cash is invested within the newest protections.
On the Commonwealth Financial institution, the purple group is a small group of full-time workers who’re thought to be a few of the most gifted hackers within the nation.
‘We now have carried out a number of work…I’ll by no means be glad that we’re totally prepared.’
CBA chief government Matt Comyn on cybersecurity
“That group was very efficient. I used to see briefings from them, they might destroy our programs,” says one former CBA developer. “They might quickly poke holes in issues.”
The group runs between two and three main tasks annually, the place they aim all the things from the web banking app to bodily ATMs.
An goal is about by senior administration and varies from venture to venture – steal knowledge, compromise code, maintain the financial institution to ransom or pinch $1 from a buyer’s reside checking account. Not like penetration testers, who stress-test the banks’ safety controls, the purple groups are “off the leash” and might deploy any ways needed to attain the acknowledged goal.
Whereas some guardrails are put in place to keep away from sending off alarms, the purple groups generally get too near the prize. “The issue was not breaking issues whereas testing,” one senior CBA supply mentioned. “Then folks would get offended”.
5 years in the past, senior administration groups throughout banks had been largely clueless about cybersecurity.
Boards and executives had been simply scared by imprecise warnings of rising threats and managers would use a advertising approach often called FUD – worry, uncertainty, doubt – when pitching for higher funding.
CBA financial institution’s former chief data safety officer, Ben Hayes, was extremely regarded by his personal workers, held sway with the financial institution’s senior executives and board administrators and ensured cyber investments weren’t “pissed up the wall”.
However after Hayes left in 2016, there was mass workers attrition which insiders say induced CBA’s defences to weaken.
Now, beneath Matt Comyn’s management, cybersecurity has change into centre stage once more. In February, CBA headhunted Brendan Goode to relocate to Australia from the US and change into the financial institution’s chief safety officer. Drawing on management roles throughout world giants Citi and Deutsche in addition to greater than six years with the US Division of Homeland Safety, the place he was aware about White Home deliberations about cybersecurity, Goode has been given a large remit to consolidate CBA’s cybersecurity and fraud groups – breaking down silos that exist at rival banks.
”The expansion in cyber-attacks is happening worldwide, as is development in fraud and scams. Per our deal with the safety of information and privateness, we’re investing a really vital sum to constantly improve our cybersecurity,” Goode mentioned in an announcement.
“This funding covers the newest programs expertise, recruiting and coaching extra folks, serving to to make sure there’s a pipeline of extremely expert expertise coming by means of.”
CBA chief Comyn not too long ago advised Parliament’s economics committee CBA had noticed a pointy rise in assaults over the previous 12 to 18 months and pledged ongoing funding to strengthening cyber controls.
“We now have carried out a number of work,” Comyn mentioned. “I’ll by no means be glad that we’re totally prepared.”
CBA will not be alone in prioritising cyber dangers. Westpac chief data safety officer Richard Johnson mentioned cybersecurity was the financial institution’s primary precedence. “We make investments closely in our cybersecurity capabilities and have strong controls to guard the integrity of our knowledge, data programs and infrastructure,” Johnson mentioned.
This echoed statements from rivals ANZ and NAB chief safety officer Sandro Bucchianeri, who mentioned his financial institution invests tens of thousands and thousands annually in lifting controls and pointed to its three-year program to improve expertise. “Via this funding, we made enhancements and gained efficiencies in what we do, however clearly the problem is rarely over, and it stays a vital focus,” he mentioned.
From North Korea to yard teenagers
As banks change into more and more refined in constructing cyber defences, the menace panorama can also be quickly altering. Insiders name it a “cat and mouse” recreation the place as quickly as one gap is plugged, one other opens.
Moral hacker Justin Waite spent 15 years constructing defence methods throughout three of the massive 4 banks – ANZ, Nationwide Australia Financial institution and Commonwealth Financial institution.
Waite, who now runs cybersecurity agency Sentaris, says main Australian corporations are paying extra in ransoms than the general public would think about.
Within the early 2000s, he says organised crime teams orchestrating the assaults had been skilled. They could possibly be contacted by cellphone and would politely clarify the steps wanted for IT staff to finish the assault.
“From a status perspective, they wanted everybody to know – in the event you pay your ransom we’re going to take care of you,” Waite says. “Within the early days, that was vital. Now, that’s gone. We don’t see the restoration we used to see.”
Over the previous 18 months, Waite explains there was a mass launch of low cost malware on the darkish net – software program that disrupts or good points unauthorised entry to an organisation’s programs. Small-fry hackers with restricted expertise can now simply buy readymade viruses and step-by-step manuals for the right way to pull off a profitable hack.
‘This can be a profitable business. It has its personal market dynamics, its personal financial system.’

This democratisation of hacking has meant everybody from state-based actors to youngsters in garages can launch an assault in opposition to a serious establishment.
“We will all the time blame COVID, and sure extra individuals are sitting in entrance of their computer systems, so it makes extra sense for crime to go up, however round that point extra ransomware code was launched to the web as nicely, so that you nearly had the proper storm,” Waite says.
Contained in the banks, cybersecurity frontline staff say numerous assaults come from state-based actors with vastly completely different objectives. The Chinese language authorities is after mental property or buyer surveillance, whereas the North Korean authorities desires cash.
The organised crime gangs, however, have a laser deal with extorting income at no matter value. If hackers acquire entry to buyer knowledge, they may try and extort the financial institution but in addition the client.
The most important gamers function with abandon from Jap Europe, Russia and Iran – the place there aren’t any extradition treaties and governments willfully flip a blind eye.
Senior fellow at Australian Nationwide College’s Nationwide Safety School and CyberCX director Katherine Mansted says it’s large enterprise, the place criminals are actually specialising in area of interest providers.
“This can be a profitable business. It has its personal market dynamics, its personal financial system.”
A brand new organised crime group, Hive, has wreaked havoc within the US and is now circling Australian corporates, she says. “The FBI put out an alert a few month in the past. These new children on the block are fairly uncontrolled,” she says. “They solely emerged in Australia in June this yr pursuing a high-damage technique.
“So long as criminals see there’s a payday, they may maintain coming into this market.”
In cybersecurity, there are three principal threats: criminals, governments and insiders.
Banks have lengthy needed to display screen and monitor their staff to make sure they’re not collaborating with criminals to tug off a heist.
“Employees can do something, it’s just like the cops,” mentioned one supply who investigates inner fraud on the main banks. “You’re given the keys to the town, till you breach that belief, you are able to do no matter you need.”
When the COVID-19 pandemic hit, companies had been pressured to shortly adapt to distant working. For banks with hundreds of staff world wide, this posed an enormous problem for cybersecurity.
“There was no management over who was taking a look at data,” says one NAB supervisor. “We didn’t know if there was somebody in India with a laptop computer in a home of 5 folks.”
Know-how builders are given digital entry to privileged data and important infrastructure. Cyber controls are sometimes much less stringent for banks’ inner programs, so criminals goal builders with bribes or extortion to realize backdoor entry.
However the line between state actor and insider has additionally change into blurred, with banks on excessive alert for governments infiltrating their ranks. One senior CBA insider says some governments have been discovered to keep away from funding analysis and growth by sending operatives to steal data from international non-public corporations.
In 2018, the Australian Prudential Regulation Authority launched new prudential requirements, dubbed CS234, geared toward lifting cybersecurity controls. One of many key areas of focus was ‘identification and entry administration’ designed to deal with the chance posed by malicious insiders.
The Age and Herald beforehand revealed ANZ employed two exterior auditors – PwC and KPMG – and went on a specialist hiring spree to tighten controls round entry and identification administration after claims former workers retained entry after leaving the financial institution.
Insiders from the Commonwealth Financial institution and Westpac say related weaknesses have been detected, and each banks have funnelled sources to make sure solely the proper workers have entry to privileged data and programs.
Efforts to raise controls by rolling out new expertise have been stymied by ageing core expertise throughout the main banks. “A few of it’s advantageous. A few of it positively raises an eyebrow,” says one Westpac marketing consultant.
Legacy programs create vulnerabilities for cyberattacks for a spread of causes – new programs are more durable to combine and updates will be painstaking as a result of the coding is extra complicated and makes use of historical languages, like Cobol and Pascal, that youthful builders don’t know the right way to use. Vulnerabilities in these programs are sometimes well-known, making it simpler for criminals to share ways for exploitation.
“It’s like having a home with actually crap foundations and constructing on prime of it,” says one Westpac marketing consultant. “There are all these issues it creates, each at a perform degree and a safety degree.”
One other downside has been the tempo of change. Whereas Westpac is taken into account gradual and cumbersome, CBA has the alternative downside. The financial institution is consistently working new growth tasks on tight deadlines, which might result in human error that journeys the system or opens safety gaps.
CBA has had a variety of service outages this yr, the place clients have vented their fury on social media after being locked out of web banking, unable to entry their cash. CBA has pledged to analyze the supply of every outage, however insiders say most of the time, it’s attributable to rushed growth work.
Whereas banks can throw cash at constructing ironclad perimeters, one constant message from the cybersecurity group is that crucial a part of any defence is folks.
The federal authorities is presently contemplating a invoice that may drive stricter cybersecurity necessities on a bigger variety of Australian corporations. For a sector already going through a abilities scarcity, it might make issues worse.
Analysis group AustCyber forecasts there’s going to be a scarcity of 17,000 cybersecurity staff by 2026. Throughout every of the massive 4 banks, workers have described an imperfect stability between the necessity to construct capability with attracting one of the best expertise.
APRA has been described as a proactive, “activist” regulator on cybersecurity, however many declare it doesn’t have the capability nor experience to successfully maintain the finance business to account for systemic weaknesses in complicated expertise. And APRA too will not be immune from the warfare for expertise, with specialist workers being poached by non-public corporations providing greater pay cheques.
