Khader is reportedly assisting the FBI and international law enforcement by walking investigators through his electronic devices and digital communications. 'His cooperation is critical to ongoing efforts to arrest these hackers,' a source told Reuters.
The detention comes amid an FBI crackdown on ShinyHunters following the group's claim that it breached FBI systems in September using an alleged zero-day vulnerability in Oracle PeopleSoft. The group said it stole between 2TB and 3TB of data, including information on current and former FBI employees, job applicants, and medical and psychiatric records. The FBI has said it is investigating the claims but has not confirmed data theft.
Earlier in September, Dutch police arrested a 24-year-old man in Amsterdam in connection with the investigation. That suspect was identified as Pepijn van der Stap, who previously used the alias 'Umbreon'. After that arrest, FBI Cyber Division Assistant Director Brett Leatherman warned other group members to surrender. 'The longer you stay in this, the more we learn about you,' Leatherman said. 'I suggest you reach out first while the choice is still yours.'
The main ShinyHunters representative continued communicating with BleepingComputer after van der Stap's arrest, indicating that he was not the person operating that messaging account. On Tuesday, the same day Khader was reportedly detained, signs of disruption began appearing within the group's operation.
