WISeKey Technologies Mitigate Cybersecurity Risks and Vulnerabilities Related to the Recent U.S. Treasury Department Breach

The recent breach underscores the urgent need for robust security frameworks to safeguard sensitive systems and data.

Geneva, Switzerland – December 31, 2024 - WISeKey International Holding Ltd ("WISeKey" or the "Company") (NASDAQ:WKEY, SIX: WIHN)), a global leader in cybersecurity, AI, blockchain, and IoT technologies, in light of the recent cybersecurity breach involving the U.S. Treasury Department, it emphasizes the critical role its Root of Trust and Public Key Infrastructure (PKI) solutions play in mitigating risks associated with third-party vulnerabilities and privilege escalation. This incident, described as a "major incident" by Treasury officials, underscores the urgent need for robust security frameworks to safeguard sensitive systems and data.

Hackers exploited vulnerabilities in the systems of BeyondTrust, a third-party cybersecurity service provider, to access unclassified Treasury documents. This attack highlights the growing risks of third-party dependencies and privilege escalation, both of which can have devastating consequences for sensitive organizations and critical infrastructure.

WISeKey's Root of Trust technology provides a secure cryptographic foundation that...

• Validates the identities of devices, users, and systems, ensuring only authorized entities have access to sensitive information.
• Secures digital identities and endpoints, and reduces the risk of unauthorized access and tampering, even in complex multi-provider ecosystems.
• Ensures the confidentiality and integrity of sensitive data through strong encryption and authentication protocols.
  
  
  
  

The company's PKI solutions further enhance security by providing robust key management, multi-factor authentication, and tamper-proof access controls. These measures secure communication channels, verify the authenticity of documents, and prevent unauthorized modifications. In the context of recent events, such solutions could have mitigated risks by ensuring that hackers were unable to exploit vulnerabilities or intercept sensitive communications.

WISeKey also addresses third-party risks through its alignment with zero-trust frameworks, assuming no entity is inherently trustworthy. By enforcing the principle of least privilege, real-time monitoring, and continuous validation of access, WISeKey's technologies limit the exposure of sensitive systems to unauthorized actors.

The U.S. Treasury incident demonstrates the increasing sophistication of cyberattacks and the critical need for advanced solutions like those offered by WISeKey. As organizations navigate an evolving cybersecurity landscape, investing in trusted solutions is essential to building resilient and secure digital ecosystems capable of withstanding today's threats.

WISeKey remains committed to enabling organizations worldwide to safeguard their systems and data against cyber threats while ensuring privacy and trust in the digital age.
