Overview
- The Justice Department executed a court-authorized seizure that the FBI Anchorage field office and the Royal Canadian Mounted Police carried out Tuesday as part of Operation PowerOFF.
- Authorities say NightmareStresser was used to launch hundreds of thousands of actual or attempted distributed denial-of-service attacks against schools, government sites, gaming platforms and millions of users since 2022.
- The specific domains taken down are nightmare-stresser[.]com and nightmarestresser[.]org and visitors now see an FBI seizure banner that blocks the service's public storefront.
- The public announcement did not name or report arrests and experts caution that seizing domains stops the public face of a booter but does not by itself remove botnet infrastructure or the malware that powers attacks.
- The action adds to a years-long campaign that has seized 100-plus domains and charged a dozen people and signals more enforcement and technical work will be needed to identify operators and disrupt underlying botnets.
