What the CME called a ‘cyber intrusion’ occurred in July, and is the subject of an ongoing federal criminal investigation.

Derivatives marketplace CME Group (NASDAQ:CME) confirmed in a communication to certain customers last week that its systems had been hacked back in July. Apparently, certain customer information relating to the CME ClearPort platform was compromised. To protect those customers, CME Group forced a change to customer credentials impacted by the incident, and is corresponding directly with the impacted customers.

To date, the CME believes that there is no evidence that trades on CME’s systems were impacted, or that clearing services provided by CME Clearing were disrupted.

The incident is the subject of an ongoing federal criminal investigation and CME Group is cooperating with law enforcement in its investigation into this matter.
