NightmareStresser DDoS Service Disrupted in International Operation

NightmareStresser, one of the longest-running distributed denial-of-service (DDoS) for-hire services in the world, has been disrupted.

The US Department of Justice announced this week that the FBI has seized the internet domains associated with the booter service.

Visitors to nightmare-stresser[.]com and nightmarestresser[.]org are now served a seizure banner.

Authorities said NightmareStresser had been active since at least 2022 and was used to launch hundreds of thousands of DDoS attacks against victims worldwide.

However, security researcher Alex Carter reported last year that NightmareStresser was likely founded in 2016 and became popular in 2018, after rival services were disrupted, becoming the largest DDoS tool in 2019.

By 2025, it had grown to nearly 1 million users. It could launch between 3,000 and 4,000 attacks per hour, accepted cryptocurrency payments, but avoided government, education, and hospital domains.

The NightmareStresser takedown was part of Operation PowerOFF, a coordinated global effort to dismantle DDoS-for-hire infrastructures globally and hold the individuals behind these services accountable.

DDoS-for-hire services, also referred to as booters or stressers, have been proliferating over the past years, as they represent low-entry barriers for cybercriminal-wannabes, the DoJ notes.

Over the past eight years, the US charged 12 DDoS attack facilitators and seized over 100 domains associated with booter services.

In April, law enforcement agencies in 21 countries disrupted 53 domains associated with DDoS-for-hire services. Last year, the US disrupted the RapperBot DDoS botnet, and 27 websites linked to booter services were seized in 2024.

In addition to disrupting DDoS-for-hire infrastructure, law enforcement agencies have been tracking and charging both the administrators and the users of these services.
