Day 0: Initial breach
9:14 AM — A regulatory affairs employee receives an email apparently from EMA requesting urgent confirmation of registration data. The link leads to a phishing page mimicking the EMA portal.
9:17 AM — The employee logs in on the fake page. Attackers capture credentials for email and Active Directory.
11:30 AM — Attackers gain email access and scan the organization: employee list, network structure, IT systems.
Defense: Security awareness training specific to pharma, MFA on all accounts, email link analysis (mail gateway with sandboxing).
Day 1-5: Lateral movement and reconnaissance
Day 1 — Attackers install a backdoor (Cobalt Strike) on the employee’s workstation. They scan the internal network, identify domain controllers, LIMS servers, and SCADA systems.
Day 3 — Privilege escalation through exploiting an unpatched domain controller vulnerability. Domain Admin privileges obtained.
Day 5 — Complete mapping: clinical data servers, production control systems, backup, and ERP systems located.
Defense: IT/OT network segmentation, EDR with lateral movement detection, regular patching, Active Directory anomaly monitoring by SOC.
Day 6-7: Exfiltration and encryption
Day 6, night — Attackers copy 2 TB of data: drug formulas, Phase III clinical trial results, patient data, patent documentation. Transfer to C2 servers in Asia.
Day 7, Saturday 02:00 — Ransomware launched on 340 systems simultaneously. Encrypted: production servers, LIMS, ERP, online backup. Production lines halted. Screens display $5M Monero ransom demand.
Day 7, 06:00 — Security notices system unavailability. IT confirms ransomware attack. Crisis management plan activated.
Defense: DLP detecting mass exfiltration, offline (air-gapped) backup tested weekly, nighttime network traffic monitoring, 24/7 SOC.
Day 7+: Response and recovery
Hours 0-24: Isolate infected systems, notify CSIRT (NIS2: 24h), board and legal. Engage IR (Incident Response) firm.
Hours 24-72: Detailed CSIRT report (NIS2: 72h), notify DPA about patient data breach (GDPR: 72h), notify regulators about production impact. Forensic analysis.
Week 1-2: System restoration from offline backups. Production resumed in limited mode. GMP data integrity verification for batches produced before the attack.
Week 3-4: Full restoration. Security hardening: segmentation, EDR, MFA, 24/7 SOC. Final report to CSIRT (NIS2: 30 days).
Total cost: ~$12M (ransom unpaid, recovery, lost production, regulatory fines, legal fees, reputation damage).

Why this matters for organizations
A realistic cyberattack scenario on a pharmaceutical company — from initial phishing to production encryption. Step-by-step analysis. 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.
