Why Payment Security is Business Critical
Maintain Customer Trust
If customers’ payment data is stolen, trust is gone—and so are they. They won’t return, and the bad news spreads fast
Protect Revenue Streams
A payment system compromise during peak season can result in millions in lost revenue. Prevention is far cheaper than the cost of downtime and lost sales
Stay Ahead of Attackers
Formjacking and POS malware keep evolving—regular testing and monitoring lets you catch new threats before attackers do
Avoid Crippling Fines
Payment card breaches trigger massive PCI DSS fines from card brands, forensic investigation costs, and potential loss of ability to process cards—a business-ending event
Frequently Asked Questions
What is formjacking and how does it affect Australian online retailers?
Formjacking (also called e-skimming or Magecart attacks) occurs when attackers inject malicious JavaScript code into your checkout page, often by compromising third-party scripts or plugins. This code silently captures payment card details as customers type them in, sending the data to criminals in real time. The original payment still processes normally, so neither you nor your customer knows it is happening. Australian retailers are increasingly targeted due to the high volume of card-not-present transactions processed domestically.
Does my business need to comply with PCI DSS in Australia?
Yes. Any Australian business that accepts, processes, stores, or transmits payment card data is required to comply with PCI DSS regardless of size. Compliance is mandated by card brands including Visa and Mastercard as a condition of accepting card payments. Non-compliance can result in fines, increased transaction fees, and revocation of the ability to process cards. Intrix provides PCI DSS gap assessments and remediation support tailored to Australian merchants.
How is POS malware installed on terminals in retail environments?
POS malware is most commonly introduced through phishing emails targeting employees, compromised remote desktop credentials, vulnerable third-party vendor access, or by physically connecting an infected USB device to a terminal. Once installed, most variants use RAM scraping to capture card data during the brief window it exists in unencrypted form in memory, before transmitting it silently to an attacker-controlled server. Retail businesses across Australia with multiple store locations face elevated risk due to distributed terminal fleets that are difficult to monitor centrally.
How often should Australian businesses test their ecommerce security?
Ecommerce environments should undergo security testing at least annually as a baseline, with additional assessments following any significant code changes, new third-party integrations, or platform updates. Continuous automated scanning between formal assessments is recommended to detect newly injected scripts, unauthorised changes to payment pages, and emerging vulnerabilities before they can be exploited. Australian businesses processing high volumes of card transactions during peak periods such as Black Friday and Boxing Day sales should consider pre-season testing as standard practice.
Can you protect our payment security if we use a third-party payment gateway?
Yes. While a PCI DSS compliant payment gateway reduces your compliance scope, your checkout pages, third-party scripts, and the network environment connecting to that gateway remain in scope and are common targets for formjacking and supply chain attacks. Our assessments cover the full transaction flow including all third-party dependencies to identify vulnerabilities that fall outside your gateway provider’s responsibility. This applies whether you use Stripe, PayPal, Afterpay, or any other gateway operating in the Australian market.
What happens if a payment security breach is detected during monitoring?
Upon detecting a breach or suspicious activity, our team immediately notifies your nominated contacts and begins triage to determine the scope and method of compromise. Containment guidance is provided in real time, and where a retainer is in place, a formal incident response engagement is activated to support forensic investigation, evidence preservation, and notification obligations under the NDB scheme. We also assist with communications to affected customers and coordination with your acquiring bank and card brands.
