NASCAR, the National Association for Stock Car Racing, experienced a data breach in March 2025 due to a cyberattack. The incident exposed the Social Security numbers of an unknown number of victims. The company identified the attack on April 3 and began an investigation, involving law enforcement and a cybersecurity firm. The breach notification letters were sent out to victims on July 24, offering one year of credit monitoring services. Medusa ransomware gang claimed responsibility, demanding a $4 million ransom and threatening to publish exfiltrated data if not paid by April 19.
