Cybercriminals have moved beyond generic ransomware blasts. They now focus on high-payoff, human-led attacks that let them quietly redirect salaries, steal personal data, or impersonate staff to open new fraud channels. The evidence is clear: the human element is present in the majority of breaches (68% in the 2024 Verizon DBIR), making HR and payroll, which hold sensitive PII and control payments, especially attractive.

A few headline numbers set the scene:
- The average cost of a data breach reached USD $4.88M in 2024 (IBM). That figure rises in industries handling financial information. IBM
- Payroll- and employee-related fraud continues to appear in fraud studies: payroll schemes accounted for roughly 10% of occupational fraud cases in recent industry reporting, with average losses often reported in the tens of thousands of dollars. CIPP+1
- Regulators are seeing more employee-data incidents: UK reports to the ICO rose in 2024, underlining growing disclosure of HR-related breaches. People Management
- In 2025, Microsoft warned of targeted “payroll” campaigns that used phishing and multi-factor authentication bypass techniques to infiltrate HR systems and alter payroll settings. These are not hypothetical threats, they’re happening now. IT Pro
What makes HR & payroll different (and harder to defend)
HR systems combine personally identifiable information (names, national IDs, bank details, health and benefits data) with business processes that can move money. That mix creates three big risks: firstly, high-value data for identity theft, secondly, straightforward fraud vectors (change bank details / direct deposit), and finally, trusted access to downstream systems (payroll, benefits vendors, identity providers). Because many attacks begin with social engineering rather than zero-day exploitation, technical controls alone won’t fix the problem. Verizon
Practical, high-impact protections for 2026 and beyond
There are some pragmatic steps that HR and payroll teams should implement immediately; they combine people, process and technology and are realistic for organisations of any size.
- Enforce phishing-resistant multi-factor authentication (MFA)
Move beyond SMS and OTPs to phishing-resistant methods (e.g., FIDO2 hardware tokens or platform authenticators). Attackers increasingly use adversary-in-the-middle (AiTM) techniques to steal OTPs; phishing-resistant MFA significantly reduces that risk. IT Pro - Apply least privilege and separation of duties for payroll changes
Require dual control for changes to bank details or payroll setup; one person to request, another to verify (ideally via an out-of-band check such as a phone call to a verified HR contact). Log and review any changes with automated alerts. - Harden third-party and vendor access (supply-chain risk)
Treat HR SaaS vendors and payroll processors as critical infrastructure: require SOC 2 / ISO 27001 evidence, MFA for admin accounts, least privilege, and contractual right to periodic security assessments. The DBIR highlights third-party compromises as an increasing vector. Verizon - Continuous identity monitoring and anomalous-activity detection
Use tooling that flags unusual payroll edits, new payees, or login anomalies (impossible travel, anomalous device or IP). Pair automated detection with a fast, documented incident cadence involving HR, security, legal and communications. - Data minimisation, encryption and tokenisation
Keep only the employee data you need, encrypt PII at rest and in transit, and consider tokenising bank details so payroll platforms never store raw account numbers. - Regular fraud audits and reconciliation controls
Schedule frequent payroll reconciliations that compare payroll runs to bank transfers and require independent sign-off for any exceptions. Fraud often goes undetected for months, whereas quick detection limits loss. CIPP - Train and simulate (but make training practical)
Phishing simulations should be role-specific for HR and payroll staff and include scenarios like vendor impersonation, payroll diversion requests and MFA-prompting social engineering. Combined with clear reporting channels, these reduce the “human element” risk. - Prepare an HR-centric incident response playbook
HR must be central in any breach that touches employee data: notification templates, remediation steps (credit monitoring, re-issuing credentials), and regulatory reporting processes should be ready and rehearsed. Regulators are increasing scrutiny on how employee data incidents are handled. People Management - Futureproof with Zero Trust and AI governance
Implement Zero Trust network principles around HR systems (continuous verification, micro-segmentation) and adopt controls around any generative AI used in HR (prompt governance, data access controls); both trends are reshaping attack surfaces and defensive options. IBM+1
HR and payroll teams are now frontline defenders of both people and money. The threats are evolving, from credential theft to highly targeted payroll diversion schemes, but so are the defences. By combining phishing-resistant authentication, robust processes (dual control, vendor hardening), continuous monitoring and realistic training, organisations can drastically reduce the probability and impact of HR/payroll incidents in 2026 and beyond.
