Cyber Incident Victim: Rudolf and Stephanie Hospital in Beneov
Date:
Jan 2020
Location:
Czechia
Summary
A Czech hospital was paralyzed by a Ryuk ransomware attack attributed to Russian hackers, disrupting operations for weeks by rendering diagnostic equipment and data exchange systems inaccessible. The incident required around-the-clock efforts to reinstall software across 600 computers and recover encrypted data, with recovery costs estimated at 40 billion crowns. While no ransom was paid and patient data reportedly wasn't compromised, the hospital implemented enhanced security measures including new firewall systems and revised external network protocols. The attackers selectively targeted the institution after covertly analyzing its systems, characteristic of Ryuk's focus on high-value organizations. The incident prompted national discussions about strengthening cybersecurity legislation.

Description
On or around January 16, 2020, the Rudolf and Stephanie Hospital in Benešov, Czech Republic, suffered a cyberattack deploying the Ryuk ransomware virus, attributed by police to Russian hackers. The attack paralyzed hospital operations for weeks, rendering critical medical equipment including x-ray machines, ultrasound devices, and laboratory instruments unusable. Internal systems were encrypted, preventing data exchange with other medical facilities. The Ryuk virus operated stealthily upon infiltration, conducting extensive reconnaissance of hospital networks and documents while disabling antivirus programs before activating its encryption payload. This rendered data inaccessible through conventional means, with decryption keys held exclusively by the attacking group. The hospital received contact instructions via ProtonMail, an encrypted email service, but Central Bohemian Region Governor Jaroslava Pokorná Jermanová confirmed no ransom was paid, denying any formal extortion demands.
Hospital IT personnel worked continuously to restore systems, reinstalling software across more than 600 computers and gradually recovering encrypted data. Patient data backups prevented complete loss, though operational recovery costs reached 40 billion crowns. The National Office for Cyber and Information Security and the Office for Personal Data Protection oversaw remediation efforts, with Governor Jermanová asserting no health record breaches occurred. Security upgrades included new firewall installations and revised external network communication protocols. Hospital Director Roman Mrva emphasized the attack's sophistication, noting hospitals face unique cybersecurity challenges due to mandatory external connections for medical devices. Full operational recovery was projected to take five to six months. The incident mirrored prior Ryuk attacks on Czech coal miner OKD and public institutions in the US and Spain, prompting Czech government discussions on strengthened cybersecurity legislation.
