This incident highlights the growing threat of ransomware attacks on the construction sector, emphasizing the need for enhanced cybersecurity measures.
Company Profile: Østerås Bygg AS

The Medusa ransomware group claims to have infiltrated Østerås Bygg's systems, accessing 125.50 GB of sensitive data. The attackers have threatened to release this data publicly within a week if their demands are not met. This breach underscores the vulnerabilities faced by construction companies, which often lack comprehensive cybersecurity defenses, making them attractive targets for cybercriminals.

The group is known for its sophisticated ransomware, which disables recovery efforts and demands substantial ransoms. Medusa's ability to exfiltrate large volumes of data and its willingness to publicly release stolen information if ransoms are not paid make it a formidable adversary.
