A Russian cybercrime group known as Lynx has been identified as the perpetrator of a significant data breach against the Dodd Group, a key contractor for the UK Ministry of Defence (MoD). The incident, which occurred on September 23, resulted in the theft and subsequent leakage of hundreds of sensitive files pertaining to eight RAF and Royal Navy bases. The severity of the breach has been described as “catastrophic” by The Daily Mail.
The compromised information is extensive and highly sensitive. It includes personal data such as the names and email addresses of MoD staff, as well as the names, phone numbers, and car details of contractors. Moreover, the leak encompassed MoD staff contacts, with a number of the stolen documents clearly labeled with security classifications like “Controlled” or “Official Sensitive.” This level of detail has raised significant concerns about the potential for exploitation.
The Dodd Group, an engineering and facilities management firm that employs over 1,100 people, provides critical maintenance and construction services across various sectors, including defense, healthcare, and education. It was through its work for the UK Ministry of Defence that the attackers gained access to the sensitive documentation. The firm remains one of Britain’s leading privately owned companies in its field.
The Lynx ransomware gang claimed responsibility for the breach by adding the Dodd Group to its Tor data leak site, alleging the theft of a massive four terabytes of data. Leaking the stolen files commenced, likely following a failed negotiation with the company. The revealed MoD documents contain critical operational details about sensitive bases, including RAF Lakenheath, which hosts US Air Force F-35 stealth jets and is believed to house nuclear weapons. Other exposed sites include RAF Portreath, a top-secret radar station integral to NATO’s air defense network, and RAF Predannack, now the home of the UK’s National Drone Hub.
Among the approximately 1,000 documents already leaked are visitor logs for RAF Portreath and RNAS Culdrose, along with internal emails, security guidance, and construction records for RAF Lakenheath and RAF Mildenhall. While the Dodd Group publicly disclosed the data breach, a company spokesman minimized the impact by stating that only ‘limited data’ had been stolen. However, intelligence experts are warning that the exposed data can be readily leveraged by hostile nation-state actors for intelligence gathering or to launch more sophisticated cyberattacks against the affected UK defense organizations. The MoD has initiated a full investigation into the incident.
