On or around May 15, 2026, SM Energy Company (“SM Energy”) became aware of suspicious activity on its computer network, indicating a data breach. Based on a subsequent forensic investigation, SM Energy determined that cybercriminals infiltrated this inadequately secured network and gained access to its files. The investigation further determined that, through this infiltration, cybercriminals potentially accessed and/or acquired files containing the sensitive personal information of thousands of individuals.
The personal information exposed in the data breach includes:
- Names
- Social Security numbers
- Tax identification numbers
- Addresses
- Phone numbers
- Email addresses
As a result of the SM Energy data breach, these individuals’ personal and highly confidential information may be in the hands of cybercriminals who can place the information for sale on the dark web or use the information to perpetrate identity fraud.
Murphy Law Firm is investigating claims on behalf of all individuals whose personal and confidential information was potentially compromised in the data breach. We are evaluating legal options, including a potential class action lawsuit, to recover damages for individuals who were affected by the SM Energy data breach.
