Greece cybersecurity signals
Follow 1 current cybersecurity signal linked to Greece through an affected location, a profiled company's country, or both, with source reporting.

HARICA Revokes SSL Certificates Due to Policy Non-Compliance and Missing OCSP URI
HARICA, a Greek Certificate Authority, announced further necessary revocations of SSL server certificates scheduled for July 25, 2026. This action affects SSL server certificates issued between March 27, 2026, and July 20, 2026. The primary reason for this renewed revocation is that HARICA removed the AIA OCSP URI access method certificate extension from issued SSL server certificates at the end of March 2026, but the Certificate Policy/Certificate Practice Statement (CP/CPS) document was not updated accordingly. Consequently, certificates were issued without this extension, contrary to the CP/CPS, making their revocation unavoidable to preserve the integrity and trustworthiness of the global certificate ecosystem. This follows an earlier revocation of certificates issued between June 15 and July 15, 2026, which included the Extended Key Usage (EKU) "clientAuth" against HARICA's policy. Affected network contact persons were to be notified by email, and while HARICA announced automatic renewal, proactive renewal via the RA Portal was recommended to avoid potential issues. User certificates are not affected by these revocations.
FAQ
Questions about Greece cybersecurity signals
What is included on the Greece page?
This page brings together current signals connected to Greece through an affected location, a reviewed company profile, or both.
Does a signal prove the attacker is based in Greece?
No. The country connection describes affected locations or profiled company locations. It does not claim actor origin unless a source explicitly establishes that separately.
Why can the number of signals change?
The page follows the rolling current-reporting window. Counts change as new incidents are added, evidence is reviewed, and older signals leave that window.
