Cybercrime squad seizes gold bullion in $600,000 BEC scam case

NSW Police and the AFP-led Joint Policing Cybercrime Coordination Centre have charged three people over an alleged $600,000 business email compromise scheme being laundered through gold bullion. A 20-year-old woman was arrested at a Sydney CBD gold dealership on 14 May after allegedly buying $100,000 of gold five times in two weeks.

Information from NAB helped Operation Dolos trace the funds to the BEC. Police also seized $34,000 in cash and three phones. 

Singapore CEO transfers US$36.3 million after fake WhatsApp call from "chairman"

A Singapore-based CEO transferred US$36.3 million in April after a fake WhatsApp call from someone posing as the company's chairman, with an urgent funding instruction. The case was one of several highlighted by Singapore Police Force's Operation FRONTIER+ III, a two-month transnational scam crackdown.

The money moved across four days before the CEO called the real chairman to verify. Singapore's Anti-Scam Centre recovered US$9.7 million; the remaining US$26.5 million was already offshore. No malware was involved; the call worked because nothing in the approval chain required independent verification before funds moved. Read more about how approval culture may have enabled this fraud.

Gartner: CFOs must lead the corporate response to AI-fueled disinformation

A new CFO.com piece by Gartner analyst Dymah Paige argues that AI-accelerated disinformation has shifted from a reputational nuisance to a measurable enterprise risk that CFOs are best placed to own. Paige groups available defences into three categories of disinformation security tooling and lays out a framework for evaluating spend by its impact on enterprise risk.

It mirrors an argument that we frequently make: CFOs are in the best position to own an anti-cybercrime strategy, and stop fraudsters from exploiting the gaps between finance and security functions.

Survey: 97% of finance teams now use AI, only 3% sceptical of payoff

A new Consero Global survey of 102 finance leaders at venture- and private equity-backed companies finds that AI adoption inside finance departments has reached 97%, up from 76% in 2025. Only 3% of finance leaders remain sceptical of future AI payoffs.

Additionally, more than three-quarters of respondents say their AI investments are already generating positive returns within 12 months. 

ASD warns of device code phishing campaign abusing Microsoft 365 sign-in

The Australian Signals Directorate has issued a warning about a phishing campaign targeting Microsoft 365 users with device code phishing. Attackers initiate a Microsoft sign-in request posing as a legitimate device, generating a code and link that the victim is socially engineered into approving.

Malicious actors are using automation and AI to request fresh codes the moment a victim clicks, making the attack significantly more reliable. ASD notes the shift away from stealing credentials toward abusing user trust in the sign-in flow itself. For finance teams, the technique is a direct precursor to BEC and payment redirection.
