From healthcare to e-commerce, the surge of data breaches in 2025 has exposed how innovation and interconnectivity, while driving convenience, have also widened the attack surface, shaking consumer confidence and testing the resilience of digital payment ecosystems.

Rebuilding digital trust in payments now demands structural change, stronger payment compliance, and smarter systems that safeguard every transaction. This article explores what went wrong in some of the most notable breaches, what they reveal about the payment security landscape, and what steps businesses can take to protect their systems, partners, and customers from cyber threats.

Rising fraud and evolving threats

Phishing, malware, and ransomware remain the most common tactics, while emerging methods like SIM swapping, social engineering, and identity fraud have surged with the help of AI.

Financial institutions, merchants, and payment processors have become primary targets because breaches here deliver immediate monetary rewards. Fraudsters exploit old software, insecure APIs, and weak authentication to intercept sensitive data or directly siphon funds.

Merchant surveys show that as merchants adopt more payment methods (cards, wallets, BNPL, real-time payments), they also perceive higher fraud risk among their most popular payment channels. Another survey found 79% of organisations reported payment fraud attacks or attempts in 2025.

Why is this happening? Several structural factors are in play:

  • The fragmentation of the payments ecosystem (more gateways, wallets, instant payments) means there are increasing points of vulnerability.
  • Fraudsters are harnessing AI, generative tools, infiltration of third-party systems and social engineering to circumvent traditional controls.
  • Legacy systems, insecure APIs, and weak authentication remain pervasive, offering the kind of low-hanging fruit that attackers exploit to intercept sensitive data or steal funds.

For merchants, gateways or fintech platforms processing payments, this means that the risk is two-fold: you’re exposed not only to direct attacks on your systems, but to upstream and downstream vulnerabilities (for example, a payment processor’s weak link, or a vendor’s unpatched system) that can undermine your entire transaction chain.

Lessons from 2025: When third-party weakness becomes everyone’s risk

Early evidence from 2025 shows how a single weak link can bring down entire payment networks. Widespread reliance on external providers, sprawling vendor ecosystems, and legacy payment infrastructure continue to expose businesses across sectors.

Below are a few illustrative cases:

  • Harrods Data Breach (UK Retail). In early 2025, the luxury department store Harrods disclosed that customer details had been compromised via one of its third-party service providers. While payment details were not exposed, the incident demonstrates how even basic customer identifier leaks can shake merchant confidence.
  • Allianz Life Breach (Insurance, U.S.). The insurance arm of Allianz (known as Allianz Life) confirmed a breach in July 2025 affecting the majority of its 1.4 million U.S. customers. Hackers exploited a third-party cloud platform through social engineering, obtaining the personally identifiable information of customers and financial professionals.
  • Marks & Spencer Ransomware Incident (UK Retail). British retailer Marks & Spencer experienced a ransomware incident in April 2025 tied to a third-party service provider; this disrupted contactless payments and click-and-collect services, revealing how attacks on vendor systems cascade into payment and commerce operations.
  • SecurityScorecard Vendor Exposure Incident (Global). In mid-2025, cybersecurity analysts revealed that several major technology firms suffered data leaks traced back to compromised third-party analytics dashboards. The affected vendors had failed to update their access-control configurations, allowing attackers to harvest client credentials and internal metadata across multiple industries. This event prompted regulators to revisit standards for continuous vendor-risk assessments.
  • Retail Checkout Skimmer Campaign (Global E-commerce). Industry reports show that throughout 2025, coordinated ‘checkout script’ attacks, similar to the Magecart operations, targeted leading online retailers across Europe and North America. By injecting malicious JavaScript into payment pages, hackers skimmed payment information and customer credentials during transactions. The campaign, which exploited outdated content-delivery integrations, led to widespread fraud and a 70% rise in credential-stuffing attempts across retail platforms.

These examples reinforce a key message: cybersecurity is a core component of maintaining merchant confidence and ensuring secure online transactions across the entire payment value chain.

Despite greater awareness of payment fraud and vendor risk, many organisations remain vulnerable to similar patterns of compromise – fragmented systems, inconsistent security standards across the chain, delayed detection, and failure to extend payment compliance and risk monitoring beyond the gateway or merchant.

Why financial and payment systems are prime targets

Cybercriminals target financial institutions and payment platforms because the potential rewards are immediate and high. Successful breaches yield both money and data that can be resold or reused in identity theft schemes.

The sector’s complexity, with its interconnected gateways, legacy systems, and high uptime requirements, creates vulnerabilities. Many financial institutions still rely on outdated core systems that cannot support modern safeguards such as multi-factor authentication (MFA) or continuous monitoring. Additionally, insider threats, misconfigurations, and unpatched vulnerabilities make maintaining digital trust in payments an ongoing challenge.

How to prevent breaches and rebuild trust

The scale of 2025’s data breaches made one thing clear: no organisation is totally immune. But these events also provide valuable lessons. Stronger security measures, improved payment compliance, and fraud-prevention strategies can reduce risk and restore confidence in online transactions.

Below are practical steps businesses can take to protect their reputation and customers’ data and trust.

Strengthen payment security infrastructure

Building a solid defence starts with reinforcing the core layers of your payment infrastructure. A secure foundation ensures that even if one barrier fails, others remain in place to protect sensitive information and maintain system integrity.

  • Implement multi-layered authentication – MFA, biometrics, and behavioural analytics significantly reduce unauthorised access.
  • Encrypt and tokenise payment data to protect sensitive information both in transit and at rest.
  • Segment networks and limit access to reduce the spread of damage if attackers breach one system.

Manage third-party risks

Treat all vendors and service providers as integral parts of your cybersecurity perimeter. Regular audits, compliance checks, and contractual obligations will ensure third parties meet the standards of payment compliance and data protection.

Before and during any collaboration, conduct continuous due diligence, evaluating each vendor’s security policies, update frequency, and incident-response readiness. Also, establishing strict data-access boundaries and monitoring vendor activity through detailed access logs and automated anomaly alerts helps detect irregular behaviour early and prevent potential breaches.

Invest in continuous monitoring and fraud detection

AI-powered fraud-detection tools identify irregular patterns in real time, stopping fraud before it escalates. This is especially important for high-risk fraud detection scenarios involving cross-border or high-volume merchants.

Integrate real-time monitoring into your payment orchestration layer to instantly flag suspicious activities, and use adaptive authentication to strengthen verification.

Maintain regulatory and compliance readiness

Align with evolving frameworks such as PCI DSS, PSD2, GDPR, and regional data-protection laws. Beyond compliance, these standards serve as a baseline for operational resilience and transaction stability.

  • Map data flows to ensure full visibility into how payment data moves across systems.
  • Conduct regular penetration tests and audits to identify blind spots.
  • Stay informed on evolving regional regulations like the UK’s Payment Services Regulations or Europe’s DORA (Digital Operational Resilience Act).

Educate employees and customers

Human error remains one of the biggest vulnerabilities. Training programs and awareness campaigns on phishing, password hygiene, and social-engineering tactics can drastically lower risk exposure. Also, simulating phishing attacks and measuring the improvement in response over time would be beneficial for the health of your payment setup.

Building a secure future: The role of payment orchestration

Payment orchestration platforms help prevent breaches by reducing system complexity and closing the security gaps that often appear when multiple payment providers and tools operate independently. Orchestrators like Corefy enable businesses to consolidate all their payment gateways in one place, apply unified fraud-detection rules, and route transactions intelligently to ensure uptime and compliance.

By providing white-label payment processing software that integrates encryption, monitoring, and modular architecture, Corefy’s approach helps companies achieve transaction stability and maintain digital trust in payments without compromising operational efficiency.

Conclusion

The breaches of 2025 exposed a clear pattern: most security failures occurred not because defences didn’t exist, but because they weren’t maintained, monitored, or extended to third-party networks.

Rebuilding merchant confidence and ensuring secure online transactions means adopting proactive monitoring and a culture of vigilance. Trust in digital finance is something organisations must continuously earn and protect, transaction by transaction.
