Goteborgsregionens Tekniska Gymnasium Listed by The Gentlemen Ransomware Group

If you are a customer of Goteborgsregionens Tekniska Gymnasium, here’s what is being claimed, and what it would mean for you.

gtg.se GTG technical upper-secondary school (gymnasium) owned by 13 Gothenburg-area municipalities (via the Göteborgsregionens kommunalförbund) — founded in 2006 specifically to solve the region's engineering talent shortage, the first inter-municipal school of its kind in Sweden. Located inside Lindholmen Science Park next to Chalmers, Volvo, SKF and Saab — a genuine "school inside an industrial cluster" with guest lectures, real projects, internships and equipment from industry partners. Programs: Teknikprogrammet (design & prod
— from The Gentlemen’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
