An APT hacking group known as GoldenJackal has successfully breached air-gapped government systems in Europe using two custom toolsets to steal sensitive data, like emails, encryption keys, images, archives, and documents. From a report: According to an ESET report, this happened at least two times, one against the embassy of a South Asian country in Belarus in September 2019 and again in July 2021, and another against a European government organization between May 2022 and March 2024.

Although their use of custom tools spread over USB pen drives, like the 'JackalWorm,' was known, cases of a successful compromise of air-gapped systems were not previously confirmed.
