Today’s guilty plea serves as a reminder to all cybercriminals, regardless of where they live, that they cannot hide behind a wall of anonymity. “Connor Moucka learned that when he was arrested just months after he began targeting U.S. companies, stealing sensitive information, and extorting victims for millions of dollars. In at least one instance, Moucka re-extorted a victim with threats of further disclosure of the victim’s stolen data. In addition to extorting victims, Moucka and his co-conspirators advertised the victims’ data for sale online, including on the cybercrime forums BreachForums, Exploit.in and XSS.is, as well as on Telegram. Moucka pleaded guilty to four counts of the indictment, including computer fraud, wire fraud, aggravated identity theft, and a related conspiracy.
