The US DoJ indicts two Sudanese nationals allegedly behind Anonymous Sudan for over 35,000 DDoS attacks targeting critical infrastructure, hospitals, and major tech firms. The FBI seized a powerful DDoS tool; victims include the DOJ, Microsoft, and Cedars-Sinai.
The United States Department of Justice (DoJ) has indicted two Sudanese nationals for their alleged role in operating the hacktivist group Anonymous Sudan. The group claimed fame for conducting “tens of thousands” of large-scale and crippling Distributed Denial of Service attacks (DDoS attacks) targeting critical infrastructure, corporate networks, and government agencies globally.
The Alleged Masterminds Behind the Attacks
Ahmed Salah Yousif Omer, 22, and Alaa Salah Yusuuf Omer, 27, stand accused of conspiracy to damage protected computers. Ahmed Salah faces additional charges for damaging protected computers.
The duo is believed to have controlled Anonymous Sudan, which, since early 2023, launched attacks on high-profile entities such as ChatGPT, UAE’s Flydubai Airline, London Internet Exchange, Microsoft, and the Israeli BAZAN Group.
The group and its clients also utilized the Distributed Cloud Attack Tool (DCAT) to conduct over 35,000 DDoS attacks. These attacks targeted sensitive government and critical infrastructure in the U.S. and globally, including the Department of Justice, Department of Defense, FBI, State Department, and Cedars-Sinai Medical Center in Los Angeles.
The attacks, which sometimes lasted days, reportedly caused major damage, often crippling websites and networks. For instance, the attack on Cedars-Sinai Medical Center forced the redirection of incoming patients for eight hours, causing over $10 million in damages to U.S. victims.
FBI Seized Anonymous Sudan’s DDoS Tool
For your information, DCAT refers to a type of malicious tool or framework that exploits cloud resources across multiple geographic locations to execute cyberattacks. These tools often take advantage of the scalability, distribution, and on-demand nature of cloud services to create strong attack infrastructures.
According to the DoJ’s press release, in March 2024, the U.S. Attorney’s Office and the FBI, acting on court-authorized seizure warrants, successfully disabled and seized Anonymous Sudan’s “powerful DDoS tool.” This tool, which the group allegedly used to execute attacks and sold as a service to other criminals, was the base of their operations.
The March 2024 operation, which disrupted the DCAT tool (also known as “Godzilla,” “Skynet,” and “InfraShutdown”), involved seizing key components, including servers that launched and controlled attacks and those that relayed commands. The warrants also covered accounts containing the source code for the DDoS tools.
“Anonymous Sudan sought to maximize havoc and destruction against governments and businesses around the world,” stated United States Attorney Martin Estrada. He emphasized the group’s callousness, noting attacks on hospitals providing emergency care. “We are committed to safeguarding our nation’s infrastructure and holding cybercriminals accountable,” he added.
Operation PowerOFF
These actions are part of Operation PowerOFF, an international effort to dismantle DDoS-for-hire infrastructures active since 2018. Private sector entities like Akamai SIRT, Amazon Web Services, Cloudflare, and Microsoft have played a key role in the takedown since.
In its latest blog post shared with Hackread.com, Akamai SIRT expressed gratitude to the FBI, DOJ, and the Big Pipes working group for their commitment to prioritizing DDoS investigations and disrupting these operations.
“Akamai would like to thank the members of the Federal Bureau of Investigation (FBI), the DOJ, and the Big Pipes working group for their commitment to prioritizing DDoS investigations, as well as their investment of time and energy into unravelling these operations and attempting to disrupt them,” the company said.
