Phase 1: Attack vector — infected resume in response to a job posting
The company publishes a job posting for an IT specialist. The attacker prepares a professional resume in .docx format, tailored to the job requirements. The document contains a hidden macro that installs a backdoor on the recruiter’s computer. The resume looks credible — experience matches requirements. The recruiter opens it as part of daily work. Antivirus does not detect the threat because the macro is obfuscated and communicates with the C2 server through an encrypted channel.
Phase 2: Escalation — from recruiter’s computer to the HR system
The backdoor gives the attacker remote access. It captures passwords entered by the recruiter — including ATS and HR payroll system credentials. The attacker logs into the HR system using stolen credentials. The absence of MFA allows single-factor access. The attacker exports the employee database: names, social security numbers, addresses, salaries, and bank account numbers. The entire operation takes a few hours and generates no alerts.
Phase 3: Consequences — from regulatory notification to trust erosion
After breach detection, the organization faces cascading consequences. Legal: notification to the supervisory authority within 72 hours, notifying affected employees, potential fine up to EUR 20 million, class action lawsuits. Operational: forensic investigation, password reset, review of all HR systems. Reputational: loss of employee trust, recruitment difficulties, negative media coverage. Financial: costs can reach millions.
How to prevent this scenario — safeguards at every stage
Stage 1 — protection against infected resumes: sandbox for attachment analysis, enforced protected view, ATS with built-in attachment security. Stage 2 — preventing escalation: multi-factor authentication on the HR system, network segmentation, activity monitoring. Stage 3 — minimizing impact: encryption of sensitive data in the HR system, incident response plan, cyber insurance. nFlo offers comprehensive HR infrastructure security audits covering all these protection layers.

Why this matters for organizations
How does an employee data breach unfold? A step-by-step analysis — from the attack vector through exfiltration to legal and reputational consequences. In the context of growing cyber threats and tightening regulations (NIS2, DORA), organizations must proactively manage this security area. Failure to implement adequate safeguards can lead to data breaches, financial penalties, and reputational damage.
Best practices for implementation
Effective implementation requires several key steps:
- Risk assessment and inventory — identify assets, threats, and vulnerabilities specific to your organization.
- Policy development — document requirements, roles, and responsibilities.
- Technical controls — deploy tools and configurations proportionate to identified risks.
- Training and awareness — engage employees in protecting organizational security.
- Monitoring and continuous improvement — regularly verify effectiveness and adapt to the evolving threat landscape.
