Colleges and universities have become prime targets for a sophisticated and fast-growing form of cybercrime: e-skimming. As institutions expand online services, from tuition payments and bookstore sales to donations and event registrations, attackers are finding new ways to intercept sensitive information at its most vulnerable point: when users enter it into a web form.
E-skimming, also known as digital skimming or formjacking, is the silent theft of data directly from a browser. A malicious script captures payment details, personal information, and login credentials before the data ever reaches the institution’s secure network.
These attacks often go undetected by traditional security tools, making them especially dangerous for universities that rely on multiple vendors and decentralized web systems.
The Urgency: Real Attacks, Real Consequences
This isn’t theoretical, it’s happening now. According to the latest Verizon Payment Security Report, more than 75% of investigated data breaches involved e-commerce websites, with third- and fourth-party scripts among the top attack vectors. Europol also recently dismantled a global e-skimming network that compromised over 400 merchants across multiple sectors.
Higher education institutions are increasingly appearing in these same data sets. Several U.S. universities have reported incidents where malicious JavaScript injected into payment or donation portals harvested cardholder data for months before discovery. The reputational fallout, combined with regulatory penalties and loss of donor trust, has proven far more costly than the technical remediation.
If your institution processes payments online, attackers are already probing your web environment. The question isn’t if they’ll try to exploit it, it’s whether you can detect and block the attempt in time.
Why Higher Education Is Especially Exposed
Campus payment environments are complex. Tuition and housing portals, athletic ticketing sites, bookstores, and alumni donation pages often run on different systems maintained by separate departments or vendors. That fragmentation creates a lack of visibility into the scripts running on each page.
Modern websites typically load a dozen or more external scripts from analytics platforms, marketing tools, chat widgets, and payment processors. Many have access to form data. When one is compromised, or when a legitimate script loads a malicious fourth-party script, the attacker gains the same privileges as the trusted code. Because this activity occurs within the browser, conventional firewalls and malware tools cannot detect it.
The Compliance Clock Is Ticking
The Payment Card Industry Data Security Standard (PCI DSS) 4.0.1, which took effect in April 2025, directly addresses this threat. Two new requirements, 6.4.3 and 11.6.1, mandate strict control over all scripts that execute on payment pages:
- Requirement 6.4.3 requires a full inventory of every script, verification of its authorization and integrity, and documentation of its purpose.
- Requirement 11.6.1 requires continuous monitoring for unauthorized page or script changes, real-time alerts, and the ability to block malicious activity.
Institutions that fail to comply face increased risk of data theft, regulatory penalties, and loss of trust. Given the scale of campus payment systems, these controls are no longer optional; they are foundational.

A Smarter Defense: CampusGuard ScriptSafe
To meet these challenges, CampusGuard’s ScriptSafe provides a practical, behavior-based solution built specifically for higher education.
ScriptSafe protects sensitive data at the point of entry, isolating and controlling every script running in a student’s or donor’s browser. Unlike static approaches such as Content Security Policy (CSP) or Subresource Integrity (SRI), ScriptSafe continuously analyzes script behavior, automatically blocks unauthorized activity, and alerts teams to suspicious changes. For more on PCI DSS browser-side protection, watch CampusGuard’s webinar, Payment Fraud Trends in Higher Ed & How to Stop Them at the Browser.
With ScriptSafe, universities can:
- Gain complete visibility into all first-, third-, and fourth-party scripts on payment and commerce pages.
- Automatically inventory and authorize scripts to satisfy PCI DSS requirement 6.4.3.
- Monitor and block malicious activity in real time to meet PCI DSS requirement 11.6.1.
- Deploy protection in hours, not weeks, with minimal ongoing management.
- Generate compliance reports instantly during audits.
This low-effort, high-impact approach delivers both security and compliance without adding complexity to IT workloads.
Protecting Students, Donors, and Institutional Trust
E-skimming targets one of the last unprotected layers of the digital campus: the user’s browser. Without visibility and control over the scripts executing there, universities leave an open path for attackers to capture sensitive information and erode public confidence.
ScriptSafe closes that gap. Through real-time monitoring, automated blocking, and built-in compliance reporting, it helps universities secure every online transaction and safeguard every member of their campus community, from applicants paying enrollment fees to alumni making gifts online.
The takeaway for higher education is clear: act now. E-skimming attacks are accelerating, PCI compliance requirements are active, and the reputational damage from a breach can take years to undo. Proactive protection at the browser level isn’t just smart; it’s essential to securing your institution’s financial and digital future.
