We’re sharing the statement it sent to clients on Thursday:
"We would like to inform you that a recent security incident has impacted our systems. Corrective action has been taken, and reports indicate that our restoration program is progressing according to plan.
While trading through our platform will remain suspended as we fortify our systems, we hope to resume operations by the end of the week.
Once again, we apologize for the inconvenience and encourage you to contact us should you have any questions or concerns."
