Current analysis on payment security, fraud prevention, AML/KYC, and PCI DSS compliance.
Fraud TypologiesA victim in Central Europe spent 13 minutes on the phone with someone claiming to be from their bank. By the time the call ended, they d installed two pieces of malware, taken out a loan they didn t r
Authentication MethodsFinCEN has warned that criminals are using generative AI to create fraudulent identity documents and synthetic identities designed to bypass verification controls. Your point-in-time authentication sy
Fraud TypologiesYou need a way to spot NFC relay attacks before they drain accounts. Here s a detection script you can deploy in your transaction monitoring pipeline today. Purpose of the Script This script identifie
Cryptography FundamentalsThe ciphertext side-channel attack against deterministic memory encryption is no longer just a theory. AMD SEV implementations have shown that an adversary can observe changes in encrypted memory and

Cryptography FundamentalsYour payment processor likely uses full-round AES. But somewhere in your technology stack, in a legacy integration, a vendor SDK, or a performance-optimized component, reduced-round implementations st
Cryptography FundamentalsYou re implementing a lightweight cipher for payment terminal firmware. The spec sheet promises strong rotational-XOR resistance. Your security architect asks: How do we verify those probability claim
Cryptography FundamentalsThe decision isn t whether to adopt post-quantum cryptography, it s when and how. With ML-KEM and ML-DSA now available in pyca/cryptography , your payment security team faces a practical choice: start
Authentication MethodsYour identity platform stopped three suspicious logins this morning. Two came from unfamiliar IP addresses. One presented valid credentials and passed Multi-Factor Authentication . All three happened
Fraud TypologiesYour Multi-Factor Authentication just failed. Not because your user clicked through a push notification or because the attacker brute-forced a code, but because they proxied the entire authentication
Authentication MethodsYour authentication stack is vulnerable through a channel you might not have considered. Device code phishing exploits the OAuth 2.0 Device Authorization Grant, a flow designed for smart TVs and IoT d
cryptography-key-managementThe Question at Hand Your encryption keys work today. Your TLS certificates validate. Your Hardware Security Modules (HSMs) meet FIPS 140-3 requirements. So why would you invest time and budget in pos
Payment EcosystemOverview of Verifone s Patent Verifone has secured a US patent for a security technology enabling payment terminals to continuously monitor themselves for physical tampering, including threats invisib
PCI DSS ComplianceScope This guide explores how to implement software-based tamper detection in POS environments, focusing on radio-based anomaly detection systems. You ll find mappings to PCI DSS 4.0 , deployment cons
cryptography-key-managementYou re managing a security infrastructure involved in payment processing, and someone just asked whether your team should start migrating to post-quantum algorithms. The honest answer: it depends on w
cryptography-key-managementPurpose of the Checklist You can t swap out cryptographic algorithms like you replace a server. Payment systems, cardholder data environments, and transaction processing pipelines embed cryptographic
cryptography-key-managementYou re looking at a vast array of cryptographic implementations across payment systems, transaction databases, authentication services, and customer records. Quantum computing threatens to break RSA,
