4d722e4d656f77 is an online threat-actor alias associated with a September 2026 public claim of responsibility for stealing customer information from CenterPoint Energy, a United States electricity and natural-gas utility. The alias appeared on a cybercrime forum advertising an alleged customer dataset. CenterPoint Energy confirmed that an unauthorized third party obtained personal information belonging to some customers through an externally facing system, but did not identify the perpetrator. Attribution to this alias, the advertised dataset's scope, and the claimed API exploitation details have not been independently established. The actor's identity, country of origin, organizational affiliations, and motivation are unknown. The incident did not disrupt CenterPoint Energy's electricity or natural-gas delivery services.
