Announcement Concerning the EUCLEAK Security Issue – Security Attack on Private Keys Stored in Hardware Devices

Since approximately September 2024, the cybersecurity community and professional media have been discussing a vulnerability known as "EUCLEAK."

This issue relates to a newly discovered cybersecurity weakness in certain microcontroller and the related firmware used in secure smart cards and tokens.

This security issue was identified and thoroughly described in a report by cybersecurity consultants at NinjaLab. The report demonstrated a specific, highly conditional way in which an attacker could potentially compromise the security of private keys stored within these hardware devices, such as tokens or smart cards.

In collaboration with our primary technology supplier, Giesecke+Devrient GmbH, we have conducted a preventive security review of the hardware technology used in STARCOS smart cards, which we distribute to customers in the Czech Republic and abroad.

We are pleased to announce that STARCOS smart cards are unaffected by this security issue. All security audits and certificates for the issued STARCOS smart cards remain valid.

We will continue to carry out preventive security monitoring of our products to enhance our security standards and solutions.
