centuryaluminum... Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The centuryaluminum... Listed by lockbit2 Ransomware Group (reported March 25, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
Century Aluminum was listed on the LockBit2 ransomware leak site on March 25, 2022. The group claims to have stolen internal data from the organization in a ransomware attack. No further details on the timing of the intrusion, the method of access, or the volume of material involved have been made public.
Who is lockbit2?
LockBit2 is the name used by a ransomware-as-a-service operation that has been active since at least 2019. The group supplies encryption tools to affiliate attackers who deploy the malware against target organizations. Its public activity includes maintaining a leak site where stolen files are posted when ransom demands are not met. The group has been linked to incidents across multiple industries in public reporting by security researchers and law-enforcement agencies.
About centuryaluminum...
Century Aluminum operates in the primary aluminum production sector, with facilities that process raw materials into aluminum products used in manufacturing and construction. Organizations of this type maintain records related to industrial operations, supply chains, personnel, and regulatory compliance. A listing on a ransomware leak site draws attention because such companies hold data that can affect both business continuity and the privacy of employees or business partners.
What was likely exposed
The only information released states that internal files were exfiltrated. The exact categories of data have not been disclosed. Companies in the aluminum manufacturing sector commonly store employee records, operational logs, vendor contracts, and technical documents; however, whether any of these specific types of information were taken in this case is unconfirmed.
Why it matters
Exposure of internal files can create operational risks for the affected organization and potential privacy or security concerns for any individuals whose information appears in those files. When the scale and nature of the data remain unknown, affected parties have limited ability to assess personal exposure. The incident also highlights the continued use of data-leak sites by ransomware groups as a pressure tactic.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
