Surge in Cybercriminal Activity Redefines Tax Season CX Risks

Surge in Cybercriminal Activity: Proofpoint Research Exposes a New CX Risk Layer in Tax Season

The 2026 tax season is witnessing a significant surge in cybercriminal activity, but what differentiates this year is not just the scale—it is the structural evolution of attacks. According to new threat intelligence from Proofpoint, over 100 tax-themed campaigns have already been identified, revealing a shift toward more persistent, deceptive, and behaviorally targeted attack models.

The research highlights a critical transition: cybercriminals are no longer focused solely on immediate financial theft. Instead, they are engineering sustained access into systems, leveraging trust-based interactions that occur during high-pressure financial workflows like tax filing.

Industry Context: Why Tax Season Has Become a CX Vulnerability Layer

The findings from Proofpoint underscore how tax season has evolved into a high-risk customer experience environment. This period combines urgency, regulatory compliance, and financial sensitivity—conditions that significantly lower user skepticism.

Customers today engage across multiple digital channels—tax platforms, email, HR systems, and financial tools—creating fragmented and complex journeys. Within this environment, the surge in cybercriminal activity exploits not just technical gaps but behavioral patterns.

The expectation of receiving legitimate tax-related communications increases the likelihood of engagement with malicious content. This is particularly relevant for CX leaders, as the challenge is no longer limited to securing systems—it extends to securing interactions.

Strategic Layer: Proofpoint Signals a Shift Toward Persistent Threat Models

The most critical insight from Proofpoint research is the rise of remote monitoring and management (RMM) payloads, which account for 39% of observed campaigns. This is not a marginal trend—it represents a strategic pivot in attacker intent.

RMM tools enable continuous remote access, allowing threat actors to remain embedded within systems long after initial compromise. This fundamentally changes the threat lifecycle.

From a strategic standpoint, this indicates that attackers are aligning their methods with enterprise digital architectures. As organizations adopt cloud-based systems and remote operations, persistent access becomes far more valuable than one-time breaches.

The timing is deliberate. Tax season provides both high engagement rates and reduced user vigilance, making it an optimal entry point for long-term infiltration.

Technology Layer: Inside the Attack Mechanisms Identified by Proofpoint

The surge in cybercriminal activity, as detailed by Proofpoint, is driven by a combination of advanced payloads and sophisticated social engineering techniques.

RMM payloads are particularly concerning because they operate as legitimate administrative tools. Once deployed, they grant attackers ongoing control over systems without triggering conventional security alerts.

Credential phishing campaigns account for 24% of attacks and are increasingly context-aware. Emails impersonate tax authorities, HR departments, or financial institutions, often referencing specific processes such as document submission or compliance deadlines.

Malware, representing 32% of campaigns, typically acts as an entry mechanism, delivered through attachments or embedded links. Meanwhile, impostor threats—though smaller in volume—add another layer of deception.

What differentiates these campaigns is orchestration. They are not isolated tactics but coordinated strategies designed to maximize engagement and persistence.

CX Impact: Trust Degradation Across Critical Financial Journeys

The surge in cybercriminal activity identified by Proofpoint has direct implications for customer experience, particularly in trust-sensitive journeys.

When users receive communications that closely mimic legitimate sources, the distinction between authentic and fraudulent interactions becomes increasingly blurred. This introduces hesitation, delays, and errors into critical processes such as tax filing.

This erosion of trust has cascading effects. Customers may delay actions, seek additional verification, or disengage altogether. For enterprises, this translates into longer processing times, increased support volumes, and reduced satisfaction.

Persistent threats like RMM-based intrusions further amplify the impact. They can disrupt services over extended periods, compromising reliability and consistency—two foundational pillars of customer experience.

Industry Implications: Proofpoint’s Findings Signal a CX-Security Convergence

The research from Proofpoint confirms a broader industry shift toward experience-centric security. Cyber threats are no longer external anomalies—they are embedded within the very channels that define customer interaction.

This has three major implications.

First, security must become a visible component of customer experience. Users need clear signals that interactions are authentic and safe.

Second, organizations must invest in behavioral intelligence. Understanding how users interact under stress is key to mitigating risk.

Third, traditional security models must evolve. Perimeter defenses are insufficient when threats originate within trusted communication channels like email.

Future Outlook: Designing CX for a Persistent Threat Environment

Looking ahead, the surge in cybercriminal activity highlighted by Proofpoint is unlikely to be a seasonal anomaly. Instead, it represents a blueprint for future attack strategies.

As attackers continue to refine their methods, they will increasingly target predictable behavioral patterns and high-engagement lifecycle events. Tax season is just one example.

For CX leaders, this necessitates a shift toward resilience-driven design. Security must be embedded into every interaction, particularly during high-risk moments.

This includes implementing adaptive authentication, contextual verification, and real-time threat detection—all integrated seamlessly into the user journey.

Ultimately, the organizations that succeed will be those that can transform security into a trust-building mechanism. In a landscape defined by uncertainty, trust will become the most valuable currency.

The surge in cybercriminal activity is not just a cybersecurity challenge—it is a defining moment for customer experience strategy.
