We continue to work closely with our platform vendor and outside security specialists to fully remediate the unauthorized phone registration activity first reported on August 24. Since our last update, we have closed the vulnerability that allowed the unauthorized access, reset credentials across affected accounts, and deployed additional fraud-detection and call-blocking protections. Fraudulent call volume has dropped substantially, and the large majority of affected accounts have been fully remediated. We are continuing to work through a small number of remaining cases and expect this to be fully resolved shortly.
We appreciate your continued patience and will keep this page updated as our work progresses. If you have questions about your account, please contact our support team at support@atlantech.net or (301) 755-2260.August 25, 2026 7:31PM EDT

We're continuing to work through the remaining steps to fully resolve the phone registration issue. A significant portion of the mitigation work is now complete, and we're focused on closing out the remaining cases.
Some devices may still lose registration during this phase. Most will reconnect automatically after a reboot; for those that don't, our team will reach out directly to affected customers.
If your device loses registration: reboot it first. If that doesn't restore service, contact Atlantech Support at support@atlantech.net or (301) 755-2260 for assistance.

After investigating, Atlantech has identified suspicious outbound call activity affecting a portion of customer calling devices, including reseller devices, that were not initiated by legitimate customers. Affected devices may have placed unexpected outbound calls or auto-answered inbound calls with silence. We have not identified evidence of a broader breach of customer data at this time.
