The Pittsburgh-based company began notifications in late December, months after stolen data posted on a LockBit site. Wabtec Corp., one of largest freight and transit rail equipment and services providers, disclosed Friday it was the target of a cyberattack discovered in June 2022. The threat actor later posted sensitive data on an online leak site. The Pittsburgh-based company discovered the attack on June 26 and following an internal investigation realized malware was introduced as early as March 15, 2022. The attack impacted the firm’s U.S., U.K. and Brazilian rail operations.
