E-commerce & retail cybersecurity Malaysia
Protect Malaysian online stores from Magecart-style script injection, credential stuffing, account takeover and loyalty fraud. PCI DSS v4.0 readiness, PDPA 2024 compliance, and incident response built for retailers whose revenue peaks on campaign days.
Payment rails, customer accounts, and peak-day fraud
Magecart-style script injection remains the most structurally dangerous threat — a compromised third-party JavaScript at checkout can silently exfiltrate card data as customers type it, invisible to the payment gateway and the bank. Credential stuffing against login endpoints is a second structural threat, using hundreds of millions of leaked Malaysian credentials from unrelated breaches. Account takeover extends to refund abuse and loyalty-point drain, and BEC against payout accounts rounds out the primary threat set — all of it strained further during 11.11, 12.12 and Raya peak windows.
PCI DSS v4.0, PDPA 2024, and BNM e-money
PCI DSS v4.0 introduced prescriptive web-skimming requirements (6.4.3, 11.6.1) directly targeting Magecart. PDPA 2024's mandatory breach notification applies given the depth of customer profile data most merchants hold. Stored-value wallets or loyalty balances with redemption value may engage BNM's e-money guidelines under the Financial Services Act. Security testing runs 4-6 weeks before peak campaigns — never during them.

Frequently asked questions
Yes, in most cases. A hosted payment page reduces scope but does not eliminate it — PCI DSS v4.0's new web-skimming requirements (6.4.3, 11.6.1) target Magecart-style injection directly regardless of gateway.
