Australia’s Big Four banks—Commonwealth Bank, Westpac, National Australia Bank (NAB), and ANZ—are under relentless cyberattacks from both sophisticated transnational organized criminal groups and lone hackers, often stereotyped as the “loser in the basement,” aiming to steal money and sensitive information.
Chris Sheehan, NAB’s executive for group investigations, highlighted the pervasive nature of these threats in a recent interview with the ABC.
“Every bank,” Sheehan emphasised, “is being attacked all the time.”
The cyberattacks are not just directed at the banks themselves but also target their customers in efforts to compromise personal information and financial assets.
The persistent nature of these cyber threats stems from the lucrative potential of banking data and the financial resources held by these institutions.
Transnational organized crime syndicates operate with significant resources and advanced technologies, often employing coordinated strategies to breach cybersecurity defenses. These groups leverage a variety of attack vectors, including phishing, ransomware, and sophisticated malware, to infiltrate systems and exfiltrate data.
Mr. Sheehan emphasised that the entire community is at risk, with no single demographic being more susceptible than others. He described the situation as “warfare” conducted on a “day-by-day” basis.
He noted that attacks originate from various sources, including individuals like “Larry the loser” in a basement at home, tapping away at a laptop attempting to steal money or hack into systems.
According to the banking executive, around 90 percent of scams targeting Australian victims come from sophisticated, ruthless, and resilient transnational organized crime gangs.
Cybersecurity expert Troy Hunt told the ABC that most people are unaware of the prevalence of online attacks, partly because they do not realize these attacks originate from all over the world.
“All sorts of different demographics are behind these attacks,” he said. “There are online attacks targeting individuals and corporations. It is truly prevalent.”
He explained that people perceive cybercrime as low risk compared to robbing a bank, and those in other countries see even less risk if extradition is unlikely.
The National Anti-Scam Centre has partnered with the Australian Financial Crimes Exchange intelligence loop to collaborate with banks, telcos, and digital platforms in the fight against cybercrime.
Together, these organizations are improving their ability to disrupt scammers by detecting and blocking scam phone numbers, bank accounts, URLs, and websites.
