eSkimming Q1 2026 Threat Briefing

April 16th at 2:00 PM EST

eSkimming/digital skimming is no longer a niche threat or a one-time incident. It has evolved into a persistent, adaptive, and industrialized attack model that operates entirely in the browser, often bypassing traditional security controls and compliance assumptions.

In this quarterly research update, Source Defense shares key findings from Q1 2026 threat research. You will see how attackers are refining their techniques to evade detection, persist after remediation, and exploit trusted technologies across the digital supply chain.

This session focuses on how attacks are evolving, not just where they are happening. From the abuse of Google Tag Manager and trusted services to silent skimming, modular infrastructure, and persistent reinfection patterns, the data reveals a clear trend: attackers are adapting faster than most defenses. 

Key Takeaways:

• How eSkimming attacks are evolving to evade PCI DSS-aligned controls
• Why “trusted” scripts, services, and first-party code are now primary attack vectors
• How attackers persist, re-enter, and adapt after remediation efforts
• What Q1 2026 research reveals about modular, adaptive skimming techniques
• Why traditional controls (CSP, SRI, WAFs) are increasingly insufficient
• What security and compliance teams should do differently in 2026

Business Outcomes:

• Reduce risk of undetected data theft in the browser
• Strengthen PCI DSS 4.0.1 alignment (6.4.3 and 11.6.1)
• Protect revenue, customer trust, and digital channels

Join us on April 16th to understand how eSkimming is changing and what your organization needs to do to keep up.
