NAB’s scam alerts intervene in $270 million worth of payments



  • Bank halts millions in payments between March and July to help protect customers from scams
  • 40% of Australians ‘extremely willing’ for payments to be slower if they were better protected from scammers
  • NAB introduces new blocks on some cryptocurrency platforms where scams are more prevalent

NAB has intervened in more than $270 million worth of customer payments which raised scam concerns in the four months between March and July, according to new insights.

Insights from the NAB app show when customers received a real-time payment prompt in app, 12% of payments were abandoned.

NAB Executive for Group Investigations and Fraud Chris Sheehan said several measures introduced in the last six months were having an impact to protect customers from scams.

“Introducing payment prompts, taking action on spoofing and stopping the use of links in unexpected text messages are among key measures we’ve introduced recently. We’re now also taking action to block some payments to high-risk cryptocurrency exchanges in a further effort to stop scammers,” Mr Sheehan said.

“The payment prompts feature a check list based on uncharacteristic activity designed to get the customer to pause and review the payment prior to hitting send.

“While many customers ultimately complete their payment after receiving a prompt, we’re seeing around $290,000 worth of payments abandoned daily. This tells us that customers are taking the time to stop and think before they make a payment.

“While we’re focused on making banking simple and digital, we’ve added this extra friction to help alert customers to warning signs. We need to everything we can to stop the crime before it happens.”

Mr Sheehan, who is a former Australian Federal Police executive, said Australia needed to have a conversation about balancing speed and safety in a digital economy.

“Our research shows four in 10 Australians are ‘extremely willing’ for payments to be slower if they were better protected from scammers,” he said.

Implementing high-risk crypto protections

It comes as NAB today announced new customer protections by blocking some payments made to high-risk cryptocurrency exchanges.

Almost 50% of scam funds reported to the Australian Financial Crimes Exchange were linked to cryptocurrency in a recent 30-day period. NAB is a member of the independent initiative, which brings together business, government, law enforcement agencies and industry groups to fight financial and cyber crime.

More broadly, cryptocurrency scams are one of the fastest-growing security threats, with Australians losing more than $221 million to them last year.

“These scammers are part of organised, transnational crime groups. Increasingly, we’re seeing them use cryptocurrency platforms to send stolen funds quickly and often overseas,” Mr Sheehan said.

“We want to make it as hard as possible for these criminals and reduce the impact on our customers.”

Action on spoofing working

Mr Sheehan said the bank’s work with telecommunication providers to stop criminals infiltrating phone numbers and legitimate text message threads had led to a 29% reduction in reports of NAB-branded spoofing scams between January and May.

“We continue to target these scams and recently announced we’re stopping the use of links in unexpected text messages as another way to try to stop the crime before it happens,” he said.

“We continue to encourage all Australians to stay alert, curious and educated about the latest scams.”

NAB is urging the public to contact their bank and Scamwatch immediately if they think they’ve been scammed.
