Kloeckner Metals Corporation Suffers Data Breach, Exposing Personal Information
On February 23, 2026, Kloeckner Metals Corporation, a U.S.-based distributor of steel and metal materials serving industries like construction, automotive, and energy, detected unusual activity on its computer network. An investigation revealed that an unauthorized third party accessed the network between February 17 and 23, 2026, compromising files containing names and Social Security numbers.
The breach was disclosed in a filing with the Maine Attorney General, though the full scope of affected individuals remains unclear. Edelson Lechtzin LLP, a national class action law firm, has launched an investigation into potential legal claims for those impacted, offering free case evaluations to assess rights and remedies.
Kloeckner Metals has not publicly detailed the attack vector or the number of records exposed. The incident highlights ongoing risks to supply chain and industrial sector entities, where sensitive personal data may be targeted alongside operational systems. Further updates are expected as the investigation progresses.
