FBI Cyber Division Assistant Director Brett Leatherman issued a video statement Tuesday warning members of ShinyHunters to surrender, hours after Dutch authorities announced the arrest of a 24-year-old Amsterdam man they say played a leadership role in the hacking group.
“Today, our partners at the Dutch National Police announced the arrest of one of the alleged leaders of ShinyHunters, a group linked to cyberattacks in the United States, the Netherlands, and around the world,” Leatherman said.
Dutch police said the suspect was arrested on September 15 and is suspected of being part of a criminal organization. After his arrest, investigators found a large amount of information on his laptop, including details about two murders that were to be committed abroad. “There are indications that the suspect gave the order for this,” the police said.
The Rotterdam District Court ruled Tuesday that the suspect will remain in pre-trial detention for at least another 90 days. Police said further arrests have not been ruled out.
The FBI says ShinyHunters and its alleged co-conspirators have breached more than 140 organizations since last year and collected at least $70 million in extortion payments. The group frequently targets corporate single sign-on accounts, third-party vendors, and cloud-based SaaS platforms such as Salesforce and Snowflake to steal sensitive data before extorting victims.
The warning comes shortly after ShinyHunters claimed responsibility for a data breach at the FBI itself, telling BleepingComputer that the breach involved exploitation of an Oracle PeopleSoft zero-day. The group claimed to have stolen two to three terabytes of data, including information connected to multiple internal services, and later provided a sample of about 5,000 FBI personnel records to media organizations. 404 Media reported that the stolen information included data belonging to members of the FBI’s Remote Operations Unit.
