Dutch police arrested the suspect in Amsterdam on September 15, before the ShinyHunters group claimed to have breached an FBI recruitment system. He appeared before judges at Rotterdam District Court on Tuesday and has been remanded into custody for at least 90 days.
The arrest was carried out by the Dutch High Tech Crime Unit, which seized his devices. Police said they found "a large amount of information" on his laptop, including "details about two murders that were to be committed abroad" that they suspect he may have ordered. Dutch officials said this investigation is separate from the ShinyHunters probe.
ShinyHunters is a cybercriminal group accused of hacking over 140 organizations worldwide, including Pornhub, Ticketmaster, AT&T, and Dutch telecom Odido. The group claimed responsibility for the Odido breach that affected 6.2 million customers and recently boasted of compromising an FBI system, telling The Register they did it "to protect our business."
Dutch police said the suspect is being investigated for participating in a criminal organization. Media outlets including Bloomberg and KrebsOnSecurity have named the man as Pepijn van der Stap, who was previously convicted of hacking, data theft, and extortion and sentenced to four years in prison. He later returned to legitimate cybersecurity work, with a company identifying him as working as an offensive security lead. The suspect's lawyer could not be reached for comment.
FBI Cyber Division Assistant Director Brett Leatherman said in a video message that Dutch authorities had arrested one of the "alleged leaders of ShinyHunters." He added that the Dutch unit "moved quickly to protect victims and preserve critical evidence" and vowed to pursue remaining members. FBI Director Kash Patel thanked Dutch partners on X, stating that FBI teams are actively working to obtain and execute more leads. Leatherman directly addressed group members: "Other groups believed anonymity or their friends would protect them... but arrests have a way of changing who is willing to talk. The longer you stay in this, the more we learn about you."
Dutch police have not ruled out further arrests. The suspect has been held since his arrest, and police said they received 20 tips following a public appeal earlier this month related to the Odido investigation.
