An as-yet-unidentified group, known only as GoldenJackal with suspected links to the Russian state, is targeting high-security networks that are intentionally isolated from the internet. Confidential data is frequently stored in “air-gapped” computers that do not have an online connection and were, until now, virtually impossible to hack.
But cybersecurity firm ESET now reports that GoldenJackal was deploying “a highly modular toolset” against a government organization in a European Union (EU) country between May 2022 and March 2024. This follows similar ongoing attacks on air-gapped systems in Belarus that began in August 2019.
