U.S. Seizes NightmareStresser Domains Linked to Hundreds of Thousands of DDoS Attacksnew

The U.S. DoJ seized NightmareStresser DDoS-for-hire domains, disrupting a booter service linked to hundreds of thousands of attacks since 2022.

The U.S. Department of Justice announced a court-authorized seizure of nightmare-stresser[.]com and nightmarestresser[.]org, conducted with the FBI Anchorage Field Office and the Royal Canadian Mounted Police as part of Operation PowerOFF. Searchlight Cyber reported in 2023 that NightmareStresser had over 566,000 registered users and 52 servers, offering Layer 4 amplification and Layer 7 floods against education, government, and gaming victims. The seizure follows earlier actions, including 48 domains seized in December 2022 and 53 domains plus four arrests this April, bringing totals to twelve charged defendants and more than 100 seized domains.

U.S. Sanctions Iran-Linked Hackers Behind Critical Infrastructure Breaches

U.S. Treasury sanctioned nearly 60 Iran-linked entities, including MOIS-affiliated Mabna Institute hackers behind breaches of U.S. critical infrastructure and millions in crypto theft.

The U.S. Treasury launched Operation Economic Outcast, designating nearly 60 Iran-linked entities, individuals, and vessels across nuclear, missile, oil, cyber, and digital asset networks. Five sanctioned individuals are members of the Tehran-based Mabna Institute indicted last week; three allegedly breached and exfiltrated data from U.S. energy, defense, healthcare, IT, and financial organizations since late 2023. TRM Labs traced roughly $16.8 million across 30 wallets tied to the members, and the State Department announced a reward of up to $10 million. The action follows Iranian hacking of FBI Director Kash Patel's email and attacks on over 30 U.S. water and wastewater utilities.
