911 S5 Botnet Dismantled and Its Administrator Arrested in Coordinated International Operation
A court-authorized international law enforcement operation led by the U.S. Justice Department disrupted a botnet used to commit cyber attacks, large-scale fraud, child exploitation, harassment, bomb threats, and export violations.
“This Justice Department-led operation brought together law enforcement partners from around the globe to disrupt 911 S5, a botnet that facilitated cyber-attacks, large-scale fraud, child exploitation, harassment, bomb threats, and export violations,” said Attorney General Merrick B. Garland.
“Working with our international partners, the FBI conducted a joint, sequenced cyber operation to dismantle the 911 S5 Botnet—likely the world’s largest botnet ever,” said FBI Director Christopher Wray.
The Department appreciates the significant assistance provided by the Attorney-General’s Chambers of Singapore, Singapore Police Force (SPF), Royal Thai Police, and the Office of the Attorney General and the Anti-Money Laundering Office of the Kingdom of Thailand. The Justice Department’s Office of International Affairs and Money Laundering and Asset Recovery Section provided crucial support to this operation. The Treasury Department’s OFAC also provided support to this operation. Additionally, the Department offers its thanks to Chainalysis, the Shadowserver Foundation, and Microsoft for the assistance provided by each during the investigation and the operation.
