The Lynx ransomware group – widely seen as a successor to the INC criminal operation – posted on its darkweb site samples of what it says is four terabytes of data stolen from the Dodd Group. The Shropshire-based firm provides electrical and mechanical services to British military bases.
A ministry spokesperson on Monday said the agency is investigating the alleged leak. “We take a robust and proactive approach to cyberthreats that could pose risks to national interests,” the spokesperson said. “To safeguard sensitive operational information, we will not comment any further on the details.”
Posted records include contractors’ names, car registrations and mobile numbers, as well as Ministry of Defense personnel names and email addresses, reported The Mail on Sunday, which broke news of the leak. The ransomware operation also posted documents that appear to relate to projects such as the installation of an oil tank or new lighting at various military bases, which The Mail on Sunday said involved British construction group Kier.
A Dodd Group spokesman confirming a “cyber incident,” told The Mail on Sunday that “limited data” had been stolen and the company had “secured and recovered our systems.”
Lynx first emerged in 2024 and primarily relies on double extortion tactics, where hackers steal and encrypt data before proceeding to leak the data if the ransom isn’t paid. Previous victims include medical service provider TriMed and America demolition and excavation company Empire Group.
The Dodd Group breach comes as the U.K. records increased ransomware hacks, with attacks against retailers costing losses worth millions. Between September 2024 and August 2025, the National Cyber Security Center recorded notable 429 incidents, the third consecutive year that number rose (see: UK Cyber Incidents Rise for Third Straight Year).
The U.K. government is reviewing a legislative proposal to put a ban on making ransom payments by critical infrastructure organizations. The government is likely to introduce the Cyber Resilience and Security Bill in November (see: UK Government Previews Cybersecurity Legislation).
