Description

On December 4, 2022, the Bl00dy ransomware gang publicly claimed responsibility for a cyberattack against Italian metal manufacturing company Lucchini Group through a Telegram channel post. The attackers declared they had compromised the company’s network, encrypted all servers using their ransomware, and implanted backdoors throughout the infrastructure. Their message, written in Italian and English, demanded negotiations within seven days, threatening permanent data loss if victims attempted independent file recovery. The gang instructed Lucchini to contact them via email for decryption tools, which they claimed would be provided upon ransom payment. Bl00dy specifically warned that restoration attempts without their involvement would irrevocably damage files due to the persistent backdoor infections.

Bl00dy, first identified in September 2022, was characterized as a "son of LockBit" due to its use of LockBit’s leaked ransomware builder to develop its own malware variant. The group appended the .bl00dy extension to encrypted files and frequently altered its malware strains to evade detection while retaining functionalities from multiple ransomware families. Lucchini RS S.p.A., the targeted entity, is a major Italian industrial firm specializing in metal production and railway component manufacturing. No technical details regarding Lucchini’s detection methods, containment procedures, or operational/financial impacts were disclosed in the gang’s announcement or subsequent public reporting. The company’s response to the attack and the ultimate resolution of the incident remained unconfirmed in available sources.
