On Oct 13, 2026, Femern (Sund & Bælt) confirmed a cyber incident at Femern Link Contractors (FLC), the main contractor on the Denmark–Germany Fehmarnbelt Fixed Link.
• FLC notified the project owner; Femern says it is in dialogue with the contractor and has no further details yet
• Local reporting (Folketidende via Ritzau / CPH Post): central systems were disabled and work on the multibillion-kroner project was significantly disrupted
• Owner has not named affected systems, outage scope, or who is responsible
• The Fehmarnbelt Fixed Link is an ~18 km undersea road-and-rail tunnel between Rødbyhavn (DK) and Puttgarden (DE); construction is ongoing (not an operating tunnel)
No ransomware group claim, data theft, attacker identity, or new completion delay has been confirmed. This affects a construction contractor, not a live tunnel operation. Do not infer a state-backed attack from the project's strategic importance alone — stick to what Femern and local reporting have actually said.
18 km of tunnel and the weak link is somebody's email
