Retailers have become prime targets for account takeover. Loyalty balances, stored cards, and digital wallets represent liquid assets, often guarded by weaker controls than financial accounts. Attackers exploit credential reuse, phishing infrastructure, and automation to scale these intrusions. Reported retail ATO cases in the UK rose 96% year over year (Action Fraud, 2023). The following five breaches illustrate how large brands across loyalty, e-commerce, and digital wallets were compromised, and how real-time, in-session defenses could have altered the trajectory.

Bank account takeover fraud is a growing global threat, costing financial institutions and customers billions each year. Attackers are refining their tactics, blending phishing, credential stuffing, and mobile malware to bypass traditional defenses. For banks, the stakes are high: a single breach can erode customer trust and regulatory standing overnight. We break down five of the most impactful account takeover attacks in recent years, examining what happened, how it happened, and how Memcyco’s real-time, browser-level, and mobile-layer protections could have mitigated the damage.

Phishing protection refers to the tools, strategies, and technologies used to detect and prevent cybercriminals from impersonating your brand, stealing credentials, and defrauding your customers. As attackers move faster and impersonate more convincingly, brands need more than just domain scans or email authentication to stay protected.

Fake apps are the latest evolution of brand impersonation, and they’re proving just as dangerous as phishing sites. Fraudsters clone legitimate mobile apps, publish them on official app stores, and trick users into entering credentials — which are then reused in the real app before anyone notices. Given that over 60% of web traffic is now mobile, this form of phishing-driven credential reuse has become one of the top blind spots in mobile fraud defense. Yet most mobile security tools can’t detect it — because they don’t know where those credentials came from.
